Magnacharger/torque converter question

[forcefedjunkie]

For those with Magnachargers, what torque converter are you using? If stock, is the stall speed good enough? I have a 3600 stall and am sure it will be too much for a roots blower. Just wondering what I should look into if/when I get the Maggie. Thanks.

Off the top of my head I dont know anyone who is running a verter and a maggie (yet) a 3600 yank would likely become a 3800-4000 with the extra torque. a 2800-3000 would likely be perfect for the blower; we'll find out soon!

Dave from Yank recommends the SC3000. I have one sitting at home, just need to find some time to get the install done. My maggie has been installed and running for about 3 weeks now.

With so much low-end torque available from the Magnacharger, is a Converter even really necessary?

Altho' I do understand how the 'verter would get it into the HP/TQ band quicker (and also have the shift RPMs improved)....

Without a converter you won't be able to make good use of that extra power.

02redhawk, have you installed your maggie yet? (I think I remember you saying you were getting one on the VMS forum.)

The maggie was certainly a nice boost in low-end torque on my AWD. But with just the stock maggie setup, I don't feel that I've reached "enough" torque... and certainly not "too much" torque.

I'm hoping to get a good boost from the SC3000... but hopefully not so much where I start to have major traction problems on the street. I guess I'll find out soon enough...

EDIT: Looking back, I may have misunderstood your original point. Are you saying that with the flatter torque curve of the maggie, there's less benefit to launching at a higher RPM? I guess that could be true. Although with the 2.4 STR of the SC3000, I think you should still see more torque off the line. In any case, I should be finding out first hand in a couple weeks. I'll report back with my impressions, good or bad.

If your going to do a converter swap I'd go with something in the 2800-3000 RPM range. This will give you good driveability and get into the power curve quicker when coming off the line.

No not installed yet. Going to wait until the Springtime...no real need for an extra 100+hp/tq in the forthcoming snow. In the meantime, its collecting dust in the basement, alongside the headers, special CAI, and a few other tricks.

Interesting....There's roughly 400tq at the wheels by 3k, isn't there? Altho' with AWD we will have a much harder time having traction issues (hee hee!). I'm postulating that we'll have to be beyond ~450awhp/tq before we start seeing sustained tire-shredding smoking AWD burnouts on the street... "Barking" them on a hard launch (or a shift with no TM) is still a bit far from having traction issues.

Yes, correct, that was my original point / question. Outside of the benefits of shift-extension, I normally associate the *need* for a higher stall to go hand-in-hand with a big cam that inherently has a lousy low-end, but a solid midrange and a monster top-end. Thus to offset the cam's lack of low-end torque, a higher stall converter is required to get the car past that laziness. We need torque in this truck, not a 500hp @ 7k rpm Supra.

Slapping in a converter along with a SC that already provides some serious low-end grunt & carries it all the way thru to redline is a new concept for me to consider..... That "need" for a 'verter seems much less of a necessity.

I think 400tq by 3k is about right. Currently, if I disable TC/ST and brake stall to around 2k, the tires will momentarily break free on the street. It still hooks very quickly, to the point where I would consider this to be "no traction issues".

There is a vendor on the other site who had several SSR customers go with the maggie + SC3000 combo. He said that his customers thought that the converter made almost as much of a difference as the supercharger. I don't have my hopes set that high, but I am hoping for a nice gain off the line. Hopefully I'll get this installed in the next couple weeks!
