Now, my 10:1 2.2 MHI red hits like a hammer and will make 480-500 lb ft around 4000-4400 Comparing it to your setup my car is a different animal at 4000 with the red, E85 and proper timing. It snaps on. The clutch in this case is the fuse.

Once I broke in the next 6 puck then ran it harder it was toast at 3K miles. I believe the taller final drive is a factor and the small hard hitting turbo on proper timing is a large factor. I do drive this car very hard but its not launched often. With the setup I had I would run 28-32psi in first and second with very little or no wheelspin.

I moved into the exedy twin for more surface area to handle the power.
