So prior to my engine build I was making 430rwhp (Dynapak) at 10psi on 91 octane.
Then the engine KABOOM'd (which I was already financially and mentally prepared for having dealt with pushing other car projects to their limits).
After the engine was built and the compression ratio lowered a full point I was making the 430rwhp (Dynojet) with 91 octane at 13psi.
Added the Flex Fuel with supporting mods and gained almost 70rwhp with the same psi.
I have busted the tranny and an axle from going WOT over a 2" drop where the overpass and asphalt meets (aka - freeway joint). Insurance paid $12k for those repairs and that was when i learned that there is only 1 brand new 5 speed left in the world as of 2012.
Yeah, mines on a built DA motor. With insane shafts. You can just feel the tranny barely hold. Did you upgrade any transmission stuff? Sorry for the thread derailment folks.
