Super T10 limitations?

[68byrd]

Hey all, does anybody know what kind of hp/torque a stock super t10 can take? Is there any way to beef them up? Thanks.

The life of the Trans will be extended or decreased by the tire size, driver habits, gear ratio, and trans internals.

I ran the BW Super T10 with a 3.42 first gear and a 2.73 rear gear. First gear was okay but the drop in RPM between gears was noticable. Since I ran a 2.73 rear gear HWY RPMs were reasonable. My motor made 421 RWHP and I ran a 225 55 16 tire (yokohama ~300 tread wear) with no issues.

What I did to make the trans stronger
1. all steel case, and mid plate.
2. I purchased a bearing set from a guy in Long Island names Lenski (last name tried to find info but none on google). If i remember corectly they had a better design to help tolerate more HP.
3. Careful driving habits (no hard launches)

I modified a muncie shifter and Tail housing of the T10 for a shifter (had the shifter already)

Just this summer I upgraded to a mini tubs and a 285 rear tires. Shortly after I lost the input shaft (suspected not inspected yet). I now have a t56.

Good luck

they put them behind 455-SD engines. I 'massaged' my SD and the trans holds so far. I don't beat it though, but do get on it. A good mod is to add t eh steel mid plate as it helps prevent twisting of the case. I'm guessing based on similar builds, my engine has around 500 ft-lbs.

I am told the lower numerical 1st gear sets are stronger. for what that is worth. I had a 2.66 or 2.64 or whatever it was in my 77, not like the 3+ ones you find in TAs, and it worked great. But not high HP.

Thanks guys. We are shooting for around 450+ hp using a Pontiac 400 with a long stroke kit. Other engines with a similar set up and hp were like 500-525 lbft of torque. Does anybody know where to get the steel midplate?

Call Jody Haag (Jody'sTransmissons), a regular at camaros.net and pops into nastyZ once in a while. He was very helpful to me and knows 4 speeds inside-out.

I have 904 iron main cases, and iron mid-plates if you can't find any... Crash
