I think that's the highest I know of with the cast plenum. Are they 2.5" outlet turbos necked down to the 2" plenum?

No they have 3” in 2” out covers because of the merge size. How much is there to gain with the other merge you are using that jumps to 2.5” right out of the turbo and ys in front of the pan sump?? Really like to be at the 1300 mark. Was making 35ish hp per pound till the jump from 22 (1189) to 25 (1241).

We haven't done a back to back on a bigger turbo necked down but do have a couple guys running that now. (You included)
We do know for sure that at about 1100whp we saw hardly any differance going dual 2" to dual 2.5". Might have to turn it up a hair more to hit your 1300whp. IF your trans will take it.

First time out with the AGP kit. Need to improve my 60 ft but that’ll come with seat time. I had my boost controller set to about 12 lbs. I’m tuned to 15lbs but when I tried setting it at 15 it would overboost.

Nice run man especially for your first time out

Did a 10.00@140.85 mph over the weekend at 12psi, 4200lbs

E85?

turn it up! nice run

Nice JMI... I need a th400 in my life :cry:

No E85 yet, car is setup for it though. Currently we run a 50/50 of pump 91 & FUSE Ignitor 116 fuel.

Thanks,will turn it up a bit next time.

M6 is fun for sure,the auto's are hard to beat at the track(drag racing).
