2006 Toyota Rav4 V6

[Prey521]

Supposedly does 0-60 in 6.7 (canadiandriver.com) (7.1 on Edmunds.com), has 269 HP and 246 lb's of torque. Friend has one, going to race him, he says he can take my '05 LT with intake and Westers Tune. TB has almost 1000 lbs on his Fag4, but I still think i'll wipe the floor with him.

[ParadoxJr]

Umm, I am thinking that he might just hang you out to dry.

They are half the size, and the TB's aren't exactly quick of the line, it has almost the same hp.

I dunno, i wanna know what happens.

:undecided

[ieatglue]

After he smokes you, drag him home!!! If you wanna, tie your truck to his "SUV" and haul him home :D

[Prey521]

Rav4 is not half the size of the TB, it's only 10"s shorter (2006 is the redesigned Rav4 that's 40% bigger than the previous gens). With all the shifting issues that those Rav4's have, I doubt he can take the TB. The Westers tune will help getting off the line and the low end acceleration, so we'll see.

[Envoy Fan]

:undecided: When's this goin down?

[1BADSS]

That new Rav4 is going to hand you your ass.lol I was going to buy one before my SS. It is a fast ******.In the 14's 1/4

[jimmyjam]

Trailblazer weight: 4417 lbs
Rav4 curb weight: 3527 lbs

not a chance... half a ton is A LOT. rav4s were reviewed as doing low 15s. You'll be lucky to get in the 15s at all. i speak from experience and a similar setup

[TonyGXP]

oh yeah, this will be a good one..RAV should....should smoke you, but I am too old to say for sure, too many variables, good luck, make sure you launch in 4wd at 2500rpm, think if he leaves light, you can take him (up to 80 or so) just don't run him too long, over 90 he'll walk you, pwr/wgt ratio in his favor big time, plus the trans..
you want NO GAS in there, and take your spare, jack and everything else out of it, air up your tires to 44psi all around...sorry, I am competitive!!!

[LAdemetri]

...just get a little 30 shot of nos.....suprise the dude a little bit :crazy:

Trust me Tony..They're quick. It surprised me.lol Toyotas quickest vehicle this year.lol

[Prey521]

Ah damn! It appears that I may have spoken to soon! You guys are right, little bastards are fast! Race is supposed to be next week! So we'll see.....I've been reading that the Rav4's have major shifting issues, lots of complaints about it, so that may help. I will let you guys know how it goes, thanks for the tips Tony!

I'm thinkin of upgrading my westers tune to the 93 Hot, which should help me somewhat.

[LAdemetri]

be sure to let us know what happens

[Braves299]

You're going to get beat. Torque Management and the HUGE subframe kills the Trailblazer / Envoys.

Don't even race him. Racing a regular grocery-getter SUV is dumb anyways... Especially if it's on the street.

What's even dumber though is a GUY that buys a Rav4... Unless he's ___.

I'm submitting my order for the 93 Hot Tune as I speak, I'm a glutton for punishment! :D

[SSmokinTB]

Good luck, you're gonna need it.

I had a 04 Saturn Vue that, for some unknown reason attracted aggressive Trailblazer and Envoy drivers. I couldn't count the number of times that I'd be minding my own business, and suddenly realize the guy beside me in the family SUV was revvin' on me. The Vue never lost (it had the 3.5L V6 Honda engine w/5 spd auto), and in most cases by 80 mph there was a 6 car-length gap. I only ran one Denali, and I pulled one car length when it shifted to 2nd, and then we stayed even. The 5 speed autos keep those small V6s wound up pretty good. The new RAV4 is slightly quicker than the V6 Vue, so you'd better throw out the spare, back seats, etc.

My Father just leased a new Vue and calls me after a trip to NY, telling me how it's faster than his 03 Acura TL!!! I really thought that was funny..why hasn't that powertrain made it into some of the cars in GM's Lineup??

Prob. because it's a Japanese motor.

:undecided I think that Honda V6 engine is made in Ohio. :undecided

[Braves299]

:undecided I think that Honda V6 engine is made in Ohio. :undecided

It's still a very Japanese design and company. A Chevrolet that is made in Europe doesn't justify it as anything other than an American car.

[1BADSS]

Prob. because it's a Japanese motor.
What about the Toyota motor in the Pontiac Vibe?

My Father just leased a new Vue and calls me after a trip to NY, telling me how it's faster than his 03 Acura TL!!! I really thought that was funny..why hasn't that powertrain made it into some of the cars in GM's Lineup??I don't remember the exact details, but GM and Honda made a deal where GM provided some diesel engines for use in the European market in exchange for the Honda gas V6 engines for use in the US. I think that part of the deal was that they wouldn't be used in direct competitors to the MDX, Pilot, or Odyssey. Honda's small SUV (CR-V) has never had a V6. Honda has since updated the engine with better VTEC, displacement on demand, etc, but the one in the Vue hasn't changed. I think it is rated 250hp/242 lb-ft torque or thereabouts. The Vue's 4.01:1 axle ratio helps get it into the VTEC powerband fairly quick, and the 5 spd helps keep it there.
The Vue isn't fast, it does 0-60 in the low 7's and mid 15s/~88mph for the 1/4 mi. But that's fast enough to surprise a lot of people who expect a weak 4-banger under the hood. It would also tow 3500 lbs, which isn't bad for a 3450 lb unibody vehicle.

The bottom line is that many of the new small SUV's are starting to pack some muscle. The Toyota RAV4 is quicker than most SUVs, and small doesn't mean wimpy any more. I think the mid-size body-on-frame SUVs have seen their last days, and 07 will probably be their last year.

My heart's with Prey521, but my money would be on the RAV4.:x

[pontiacguy]

It seems that many are predicting the swan song for mid-size body on frame suv's in light of the increasing proliferation of crossovers. Many seem to applaud this scenario. I for one don't get it. Such crossovers will not serve my needs. My Envoy is used off road in snow and mud to get me to hunting camps and to pull a trailer of atv's, as well as getting my wife and I to our winter getaway in upstate New York. Simply could not manage without a transfer case and towing capability. Anybody out there feel the same as me? Or are most of you guys looking forward to the Enlave/Acadia/Outlook?

The Honda Ridgeline would have no problems doing what you need to do.I don't mind if GM kills the Trailblazer. It means I don't have to worry about too many SS's on the road. I like a niche vehicle.I don't tow or go hunting.If I did I'd just buy a truck.

Yeah, I definitely feel the same way. I've always owned at least one S-10 Blazer and I love them, but when I got a wife and we had our second kid, it was starting to feel cramped. So I tried a Tahoe for a couple years, and I didn't like it cuz it was just too big & underpowered ('98 w/vortec 350). So I got the TB and that is perfect for me. My Blazers have frequently been used to tow snowmobiles & 4-wheelers, and then when I got the Tahoe we decided to get a small travel trailer too, so whatever I own NEEDS to be capable of towing at least 6000 lbs. I will be extremely p!ssed if they quit making the TB. I've never owned anything but GM products, but I'm not against looking elsewhere if something fits my needs better.

[Envoy Fan]

The Honda Ridgeline is just a wanna be truck. No 4-Low, no V8, overpriced.

What about the Toyota motor in the Pontiac Vibe?

But the Vibe is practically a Toyota Matrix with a Pontiac badge slapped onto the grill! Comes off the same production line, just like the old Geo lines were nothing more than rebadged Corollas and Sidekicks. - Pontiac was left empty handed when they didn't get a Malibu variant, so they had Toyota make them the Vibe. (Not sure, but I believe its assembled in their joint ventured plant in northern California that previously made the rebadged Corollas).

[LAdemetri]

hey prey521, did you race the rav4 yet............im curious after all this talk..

[kansanpoker]

umm , honestly , i dont care if there fast or not , only people i see drive rav4 are gay guys and girls , there ***** looking suv's to me

[brdnboy77]

It doesnt matter who wins because you will still have a TB and he will still be driving a Rav-4 so we know who really wins:)

[Envoy Fan]

hey prey521, did you race the rav4 yet............im curious after all this talk..

How about an update? :undecided

[gmcman]

I'm going to be a bit optimistic about this one.....what gears do you have? If you have the 3:42 you may have a problem but the 4:10 will help. The thing about the RAV-4 is yes it's light with good power but you have the better motor just more weight to get rolling. The 4.2 has a ruler flat torque curve above about 2500 RPM's and will help you dramatically once your moving. Don't launch in 4WD that will rob your power, power brake it at around 2000-2200 and just mash it when the hottie drops the flag. MAKE SURE you have 93 in the tank and MAKE SURE if you have 87 in beforehand drive easy for about 20 miles before you start romping it or it will go into a low octane map. The computer is a learning ECM so if you lolligag around then line up next to this.......RAV....the brain will still need to adjust, you may lose precious HP:) A little leadfootin' around before the main event won't hurt. I have the 4:10 and it has helped me many times to avoid embarassing kills.

If by chance he takes you on the launch I think you will reel him back in, the 4.2 pulls like a freight train from 50-80. If you lose,........:cry:

The Vibe IS a Matrix. Even though Pontiac designed the interior of both cars. Some people buy the Vibe just because it's a rebadge Toyota that's a Pontiac. Pontiac did get a Malibu variant and it was in the works when the Vibe came out. The Vibe was just something else for Pontiac to get for a small hatch/car.

I agree, but with the Westers tune he (probably) runs 91+ all the time anyway.


And, as for the I6 pulling hard from 50-80, I can attest to that. Racing my friend's XC90 I6 turbo was a challenge as he got a good jump on me, but once I shifted into 2nd, I pulled him back really fast.:yes: Still need to get him again as we ran out of road as there was construction ahead and didnt want a ticket going 20+ over in a construction zone.:no:

Why would he go from 87 to 93? The computer won't advance the timing for you. Why would the ECM cause you to lose hp if you don't drive like a maniac all the time?
If by chance he had regular in the tank for daily driving, the PCM needs time to adjust and choose the higher octane map.

ummmmm????? on a good weather day it would be a race, i am bone stock no tune or nothing and i would not be scared

[jimmyjam]

ummmmm????? on a good weather day it would be a race, i am bone stock no tune or nothing and i would not be scaredhave you ever taken your TB to the track? have you ever gotten into the 15s? because I couldn't. good weather doesn't matter when you're racing head to head, because its good for your competition too

I'd be interested in seeing the slips such a get-together....

[Prey521]

Sorry guys about not updating. He's still waiting for it to "fully breakin" before he runs it hard in a race. He said something about waiting till about 5,000 miles! WTF!!! I told him that it doesn't take that long for a breakin!! Says that he read it on some Rav4 board :crazy:

Either way, he's at 3K now...........

Also, with my Westers tune, I run 87, but would put 91 for the race.

Another thing, ever since my TB rolled over the 11K mark, it has been running like a BEAST!! It's been pulling much harder on the lower end, and I mean HARD!!! It's actually pretty cool I barely tap the gas and the intake is already growling and it pushes you back in your seat, even my wife noticed it! :rotfl:

As soon as this mofo is ready, I'll let you guys know, and no, I'm not scared, even if I do lose to the Fag4, I'm pretty sure that I'll give him a run for his money :D

Saw one at the track this week run a 14.78 @ 95 mph. I don't think even with a tune the 4.2 in the TB or Envoy stands a chance. It may even give some of these guys with the horrible times in there SS a good run.
They scatt real good for a 6 banger.

Yeah i am in the 15's i will scan the slips for you as soon as i can. Weather maters when you are goin for times!!!!!
Reaction time matters when you race head to head!!!!
i have been goin to the track for a while i have about 30 runs in my tb alone, true not all are in the 15's most are low 16's, but regardless it is possible to get into the 15's,

just cause YOU can't drive your tb into the 15's does not mean it ain't possible

[jimmyjam]

thats great and all but you're still not going to beat a rav4
just cause YOU can't drive your tb into the 15's does not mean it ain't possible
you'll note I didn't say 15s weren't possible. please re-read for clarification. what i was trying to get across is that high 15s aren't going to cut it.

How much **** did you take out of your truck to get 15's?

[gmcman]

I wasn't payin attention and didn't notice you have a tune, my bad. But a RAV 4 in the 14's......yikes:eek: That's pretty stinkin good. I wonder if it was modded???? Do they have the dealer option for the SC?

[trailblazingold]

Heres an Idea after he beats you challenge him to a pull off, tie a rope to your rear bumper then to his and hit the throttle and watch his foriegn piece rip apart then walk over and ask if he wants to run again.

Bone stock. They're quick. Don't weigh much. No SC yet since they just came out, but I'm sure TRD will have something for them soon. Quickest SUV in it's class and Toyotas quickest vehicle this year.

What mods do you have and what was removed from the TB for the run?

[vetruck]

If by chance he had regular in the tank for daily driving, the PCM needs time to adjust and choose the higher octane map.

Who ever told you that the ECM will adjust for higher octane fuel by itself? Cause it won't without a tune unless there's something I don't about these TB's. If thats true put some 114 in.


Whens the race gonna be?

[1BADSS]

All his seats were out, other then the drivers, no spare, 2WD:rolleyes:

114 is leaded, and ask any body that tunes, if you flash the computer, and use a higher octane fuel you will get good results, i have personally tried it. and i got into the 15's with just basic race trim no spare tire, no back seat, i removed the pass headlight, air filter and reflashed the computer, with some 100 octane on a good weather day

[jimmyjam]

what do you mean "flash the computer" ? are you talking about resetting ECM, or reprograming the FLASH prom with a different parameters? because thats what we're calling a tune

[vetruck]

Well I don't know what to say to that, sounds like you have it all figured out but in my truck I don't run a higher octane than what it calls for. Plus, no one ever said anything about reflashing anything, someone told him to just drive hard for a while and the computer would learn a new octane map. I don't think so but I've been wrong before :) . Also, I said 114 as an extreme example to make a point.

[gmcman]

From what I understand the ECM will adjust from 2 different maps. I don't think 115 is part of the logarithims but that's a different case. The ECM is a learning computer and constantly makes changes and updates itself, resulting in smooth and efficient engine management. When you start your truck cold or hot, take off from a start cold or hot, steady cruise. cruising with a load, WOT, and the air/fuel mix and spark timing vary epending on barometric conditions, temperature, when the redskins made the playoffs last, etc. The ECM will remember if it gave too much spark advance or fuel in the above conditions and probably has more than I listed, who knows, it senses knock and lean conditions, rich conditions, etc, etc.

When your cruising along at 50 and the explorer pulls along side and you know it's "go time" when you mash the gas the ECM will set fuel delivery, spark advance based on stored averages for that given situation taking into consideration weather conditions and fuel quality (octane). It will give you the most spark advance it can without causing knock, you will get more advance with higher octane. The trick is to have the motor respond as quickly as possible with the appropriate adjustments ready as fast as you hit the gas.

The thing is you can't have all that good advance with 87, so the ECM will work on a different set of values because when towing, climbing big hills, you put more load on the motor and you get different timing and fuel delivery for that.

Now what I heard when you fill the tank up with 1/4 tank or more the ECM will accept the fact you may have added higher octane and will give the ECM a chance to give you the higher map. When you start driving it will look for knock and will increase the spark timing until it senses knock and if it has gone into the range of higher octane it will switch maps and will keep it until another fill-up. Now that you have more advance if you start knocking and pinging alot (you probably would not hear it) it will resort to the lower map and you will be safe from the harmful detonation.

You probably ask why wouldn't it just look for the higher octane constantly and change accordingly? I would think there is too great a range of parameters for the ECM to follow and would cause the motor not to run as smooth. If you had to babysit would you want to watch 2 kids or 8, just easier on the ECM.

For all you ECM guru's out there if this is not the case please correct me or add to it, I didn't write the book just passin' along the info.

[jimmyjam]

I'm pretty sure that only aftermarket tunes have two tables, the ecm code that comes from the factory does not, only 87

Now that you have more advance if you start knocking and pinging alot (you probably would not hear it) it will resort to the lower map and you will be safe from the harmful detonation.

You probably ask why wouldn't it just look for the higher octane constantly and change accordingly? I would think there is too great a range of parameters for the ECM to follow and would cause the motor not to run as smooth. If you had to babysit would you want to watch 2 kids or 8, just easier on the ECM.

For all you ECM guru's out there if this is not the case please correct me or add to it, I didn't write the book just passin' along the info.

Where did you get this info your passing along from? If the source is not even reliable enough for you to be confident posting it you should state that instead of just posting stuff and waiting for it to be questioned. I don't think the PCM will adjust for higher octane fuel by itself. It should be set for 87 octane since thats what GM says to run.

You sound about as confident as I am.

Here's a pdf of what is in your truck, there is alot to understand about OBD II. Not much to read but it states that it adapts system to octane levels, if that will satisfy. I felt confident enough to post my explanation, which is why I did. Perhaps I am wrong, my post is as much a statement as it is a question to the experts. If areas need clarification then I will learn from that as well. There are many ins and outs and secrets of the OBD II, looking for a good book myself.

Yeah i am in the 15's i will scan the slips for you as soon as i can. Weather maters when you are goin for times!!!!!
Reaction time matters when you race head to head!!!!
i have been goin to the track for a while i have about 30 runs in my tb alone, true not all are in the 15's most are low 16's, but regardless it is possible to get into the 15's,

just cause YOU can't drive your tb into the 15's does not mean it ain't possible

yeah....umm....I would love to see the slips so I can compare whats going on. I have a tune and CAI and ran 16.1 with a temp of around 45 degrees. It was a crappy launch, and I am confident that it will get into the 15's with some prep. But you did it without a tune? or CAI? In warmer weather? I would like to see the slips so I can figure out where I went wrong.:cool:

[ScarabEpic22]

I'm pretty sure that only aftermarket tunes have two tables, the ecm code that comes from the factory does not, only 87
My stock PCM tune has dual tables according to EFILive, and the values ARE different from each other.


@ vetruck, the ECM will adjust itself to higher octane as it does have 2 tables, one for 87 (low octane) and another for good gas or 91+ octane. In I6 trucks, the PCM does the same thing, just the octane tables are different as 87 is the high one and the low is for lower octane. The ECM and PCM sense if the fuel level rises more than a 1/4 tank, they will try the higher table. If it knocks, it reverts back to the low one.

I see what you mean. It says the EFI commercial ECM has Optimal Spark Control which adjusts for a variety of factors including octane changes. I am shocked, never heard of anything like that before. Now I'm wondering why this isn't common knowledge and why there is so much to be gained from tuning and advancing the timing tables? I'm wondering what parameters it can adjust itself to, whether it can account for 93 octane or just for the minor octane differences in fuel rated at a specific octane. It said the ECM's could have two different tables loaded on them but that the ECM needed to be reflashed to use the other table. Good info to know, thanks for the link.

The reason there is such a tuning gain is from removing the TM to make it use more useable power, tune the A/F ratios more towards stoich, and not have a low octane option.

Mabey, but I don't think Diablo removes the TM, the A/F ratios should be set just about right unless there are modifications (BTW what is stoich?) and the info in the link stated that if the ECM has two octane tables one would have to reflash it in order to use the other table. So I'm still wondering why a tune delivers so much if the ECM will make the proper adjustments itself? As long as it works who cares except the tuners I guess right? :D

Stoich is 14.7:1

I have wondered that as well as my simple playing around in EFILive has yielded some awesome gains on 87 octane, and Im sure if I learned to tune for 91+ I would be getting some more neck injuries!:yes: :cool:

[dntnvme]

Well guys I think prey has a chance. For 2 reason; Reason # 1 is prey is more comfortable with driving his TB. Which gives him a little more confidence, and drive. Reason # 2 is prey has the tune, which gives him the extra power.

Other driver, not comfortable with new car. Will think to highly of new the vehicle to run it hard. Pshycologically will feel like they are doing damage to their new vehicle. Causing them to not drive as well, or push the vehicle to it's full potential. On that note, prey has a chance. I gathered this info when prey mentioned the break in thing. Unless he has a trick up his sleeve then prey needs to watch out.

lol obviously.... Toyota RAV4's are no joke.... I6 GMT360's don't stand a change in hell....:no:

[cresman3]

Sorry guys about not updating. He's still waiting for it to "fully breakin" before he runs it hard in a race. He said something about waiting till about 5,000 miles! WTF!!! I told him that it doesn't take that long for a breakin!! Says that he read it on some Rav4 board :crazy:

Either way, he's at 3K now...........

Also, with my Westers tune, I run 87, but would put 91 for the race.

Another thing, ever since my TB rolled over the 11K mark, it has been running like a BEAST!! It's been pulling much harder on the lower end, and I mean HARD!!! It's actually pretty cool I barely tap the gas and the intake is already growling and it pushes you back in your seat, even my wife noticed it! :rotfl:

As soon as this mofo is ready, I'll let you guys know, and no, I'm not scared, even if I do lose to the Fag4, I'm pretty sure that I'll give him a run for his money :D



hey i have been reading this for some time. my wife has a new rav4 2007. i had to try this to see what was all the fuzzzz about well i told her to floor it i floor my envoy xl, at first she was pulling away from me then when i hit around 45 50 i started to pull away or should i say catch up. when i hit 90 she was not catching up. when i got home she had told me that she had let go off the gas at 70 75. that means when my bro gets home i will do it one more time see what happens.

Is it a 4-cylinder???


There's no way in hell an I6 Trailvoy can keep or pull on a 2GR-FE 3.5 liter V-6 powered Toyota RAV4.

They do 0-60 in 6.4 seconds and a quarter mile in 14.8@95mph


No way a vehicle (SWB too) that runs low 16's in the quarter is anywhere near it.... :no:

[gmcman]

The power vs. weight is the enemy......shave about 1300 lbs off our midsection and we may have a chance. Them new RAV's haul arse....I wouldn't have thunk them "toys" would put a hurtin on us :hissy:

[NIevo]

Wow, all that reading and no results? Ive got to start skipping to the end of these long threads to make sure something actually happened.

nope its a v-6 but she did say she took her foot off the pedal at 70. till then it was side by side well she was a little ahead but not by a lot. going to do it again i just wanna see for myself if its that fast faster from my envoy. keep in mind its the xl a lot heavier then the rav. i do have the pcm tune and the cool air intake and a nice muffler, its lower for better handling. the rav is stock for now.

something HAS to be wrong with that thing..... They have 269bhp and run 0-60 in 6.5 seconds. Your XL Envoy runs like 8.7-9.1 in the same category.....

:no:

ok i did it again this time i was driving the rav4 and my bro was in my envoy. i have to admit i like the way the rav feel and handles. again i was up with the voy at the end about 75 the voy pulled away not by much, at 90 the voy was on its way. oh it might had been when the gov kicked in on the rav at about 90 on the voy it kicks in at 100. this test cost me a speed ticket well my bro got it but i am going to pay for it @#$#!

[cresman3]

the guys at work were telling me that the rav might be slower b/c it has not been broken in yet. i dont know how true this is but its someting to think about.

[Element207]

My moms new Rav4 beat my TB :o But my TB wasnt shifting right :cool:

[tylerfm]

No doubt gonna start from the end on these long posts to make sure something actually happened!! Prolly did loose and doesn't want to post.

Too funny about the tow challenge. We all know what'd happen there!

[NotForBling]

It's funny on here how some people post times that are from "Car and Driver" or other magazines. My old sunfire was rated from a magazine to run 15.8's bone stock all day yet the best 99% of people could do with them was
16.1's at best. I used to belong to a car club for them and watched in horror so many times at the track. There is a big difference between real world and professional drivers. There are too many factors to consider when these numbers get posted. Temperature, wheelspin, reaction time, weather, location, etc etc.

I laugh when pepole tell me "well the magazines say my car can run this fast" becasue a lot of the time it's the driver not the vehicle that determines who wins. I've seen races where someone has lost to a "faster" car and then the guy who won ran the losers car and still won against his own car.

Times posted in magazines are BS...realworld times are a lot different. When people give me this BS I just say sure buddy...see you at the track and let me know if any of my tail lights are out.

Mine has 270 HP so I will win :D...................i'm kidding.....so dont:p

[cmadams4]

I ran a Rav 4 at the track last Friday. I remember his time was 15.6, can't remember the MPH. DA was 3850 so my rule of thumb is 0.5 seconds for every 2500 ft, seems to work well for me. Works out to about 14.83 at sea level for him.
