How much power is likely added by increasing a motor 1 point of compression? I went 500rwhp at 11:1 SCR and now have 12.5:1. Just curious what you guys think. I just havent been able to dyno it yet.

 

not much peak but it will pull harder down low in the rpm's.

 

anybody else?

 

On DynoSim I changed the compression from 9.8:1 to 10.75:1 and it went up 20 horsepower. Not sure how that correlates to your motor.

 

general rule of thumb is 4% for each point of compression. Engine Masters did a test of this on a GenI and it pretty much held firm. So 500 x .04 is about 20hp for each point of SCR higher. That is not scientific of course.

thanks guys
