My car has a pretty much brand new D&D performance t56 the only have one and its suppose to be the best on the market viper spec with viper gearing witch I think the taller viper gearing is helping with traction. Im keeping the car at a very conservative 700whp at 15 psi THP twin 61mm. Do you guys anticipate transmission failures at this power level? I do drive the car very conservatively.

U sold the auto?
transmission failure no
clutch failure. more often than you'd like
I ran that transmission with a few different clutches and never could get it right. Finally sold it all and went auto. Best decision since the turbos had gone on.

I didn't sell the auto I sold my car and got another one because I wished I didn't sell it... It's actually a car I owned before lol.
what clutches did you go through? at what power?
I blew my T56 after 4 HARD years with the whipple and a 1 year and a bit with the turbo. My input shaft got crewed up on the inside. I am still on the same clutch I had in the old trans and it still grabs great 5 years and counting. It's a early RXT.
Yep my RXT looks perfect after 6k miles and 700+rwhp(it made more on e85 with the prior owner). Like younggun said though my input shaft was FUBAR'd from the excessive heat on long pulls. I replaced that and the rest of the trans looked good. If you have any issues it will be the same thing unless you do a pump to hit the input and cluster gear with fluid directly.
