I don't post on here much. But I have read a lot and found about 99% of the answers I have searched for. Thanks to all the helpful folks on here. Anyway I ran my truck this weekend here at Caprock motorplex in Penwell Tx
Got there really late. Was only able to get in 1 pass. But my pb so I was very happy.
10.95 at 127.75. Feels great to finally brake them 10s da was around 4500.

Nice! DA has little effect on Forced Induction motors.

Wow great times!

Rowing too... very impressive! Is it a 2wd? I'm surprised youre having such luck with the t56... I didnt think they liked big power and a lot of weight.

Thanks. Yes it is 2wd. T56 has held up for over 2years now. But will be swapping to an 80e soon. I just really wanted to brake 10s with the t56.

Good deal, how much boost?

Normally I run 12 psi. That's a 3" upper pulley But on this pass I installed a 2.5" pegged out the 2 bar map. So 15 16psi. Might try a 2.7" see if it doesn't run the same. I gained 4 tenths and 5 mph swapping to the 2.5".

I'd be willing to bet the pulley swap gave you more than 3 PSI... I'd bet 16-17 PSI.

With a maggie the rule of thumb is 1# of boost for tvery .1 taken off the snout pulley diameter.

Most likely. One thing I was surprised with was the ait temps. They reached 150s. My old mp112 ran a lot hotter with a 2.8pulley.

I can promise you that isn't the case.

Ya I agree. Da does effect times.
