Compression Check

[project13nsx]

I am going turbo really soon with a high boost application. Can anyone tell me how to calculate what compression pistions i need for running 12psi about 500 hp to the crank. Give or take 30 hp.

Thanks in advance!!!!

You can run 12 psi on the 9.6:1 JE's if your fuel and timing curves are correct. Dad's been running a full bar using them for years without a glitch.

Best regards,

Thanx for the reply.

What do u think if i run about 20-25 psi???

What size pistons and what else i have to do to the motor to make it reliable?
