> looking sick there bud, and good luck with youre goals. depending on how efficent you setup is youll gain anywhere from 20 to 30rwhp per psi. I gained 29rwhp per psi. with that being said you should be around 730 rwhp around 13/14 psi which should easily get youre car into the 9s with a solid 14X mph

think its that high? I was figuring high 600’s with 80-82% loss through the th400 and ptc converter. Still close to 800 hp on 12 psi, abit over that on 13
