i have a tranny from SRT but its just the stock tranny with valve body, sprag, TC, and tranny cooler upgrades. are the boost logic ones good? i would rather not go with SRT since they take so long to get anything done.

Yeah, I am constanty hearing that about SRT. I am not sure if Boost Logic specifically builds the A650E, but I know they do the A340E. I would say give them a call and ask them to be sure. I would also be interested in a tranny build from Boost Logic.

Sweet, congrats man. How does it run with 430 rwhp? How well has your tranny held up at that power level? You got any videos?
A built tranny should be able to handle high 5's, it all depends on how much you beat on it and how well it is being cooled. However, some people have broken their built trannys in that power range or less. But it also has to do more with how much rwtq you are making and your redline. If you raise the redline, it puts more stress on the tranny, and that is where most guys have broken their transmisisons. Anymore and I would start looking into atleast R154 swap. Good luck and keep us updated.

It is not so much how much power the transmission will hold, but more importantly for how long? You could push 700rwhp through a built tranny but how long will it hold? Maybe a couple dyno runs? A week? Three months?
So black_gs99, no burnouts or donuts? Do you go to the track?

If it's the SRT race build setup, then it should hold around 500-600rwhp. The main thing that goes out on these tranny is the sprag. I had mine built by PFS initially and it crapped out at around 400-450rwhp. Worst money I've ever spent in my life. I had a transmission builder(he specializes in drag racing transmissions) about 1.5hrs away from me build my trans up for me. So far this thing is works incredibly compared to the PFS one. I was running around 30psi on my PT67 turbo and the transmission had no problem holding it. I'm about to get my car running with the HKS T51R turbo at 30psi+ and really put this thing to the test.
