Hi Comp Motors

How much Compression are the fast nitrous Iorn Block ls1's running....

My motor is currently being machined and pistons are a 13cc dome and 65cc head. Iwas planning to do a dual stage nitrous setup for a total of 300-400hp

anyone running 15:1 compression or more on that much nitrous?

Good luck

I've followed your build for a long time on CF, Since you've done it before would you recomend lowering the compression to mid to low 13's?

I would if you were running N/A I could see you running 15:1 but on spray that's a lot.

Just my 2 cents Other may feel differently did you post in the nitrous section

Not an LS motor, but we have sprayed at 15.8-1. All parts were best of the best and it was a old N2O tune up that was used many many times. Good luck.
