Whipple Dyno Sheet, Stock Bottom End!
Mods are in sig this was done on 93octane and alky injection on a 3.5pulley...
Sadly I just can't launch well enough with the power. Soon to have a new trans from RPM . Going to the track tonight to see if the extra 50whp sees a gain in et or trap.

If i was you i would lower your rpms .. i think 7200 is overspinning it on a stock bottom end..

But very very impressive nonetheless. In all honesty the stock bottom will die sooner or later at this rate. I say the bearings or con rod will go first

It has been spun to 7400rpm in the past, and has been over 650whp since October of 2009....Time bomb probably. So far so good. I wouldn't recommend this to anyone else clearly.

Haha ...as long as you know. I was doing these high revs all day with a similiar set up, It seemed like it would last forever. Some people are lucky...But then I have heard of people doing just one pull or run, and boooomm..its over...lol

Oh ya i'm aware...this car has been lucky so far haha. I'm sure its bound to run out sooner or later... Hopefully the new motor goes in first or it breaks after LSX Indy.
