Cam and blower combo My friend has a Vortec YSI running 22-24lbs of boost. His current cam is not ideal at 248/252 .558/.575 on 110LS.
His question is how much power do you guys think is being left on the table vs. picking a cam with say a 114 or better LSA or something more ideal to his setup?
I dont think this matters to much but just in case this is a Ford 306.
Thanks,

Possibly none. Consider this, as rpm increases the time for charge short circuiting decreases. There is more power to be had from purging the cylinder/chamber of exhaust than a little bleed off of airflow which diminishes with rpm. What kind of power/performance does he have?
With 21 psi I made 754rwhp. But when I last dynoed I made 680rwhp on 18 psi and went 144mph. I went 9.4@144 with no changes. I have been running a 236/246//114 cam and shifting at 7000. I'd hope with that much boost that he would run more like 145-150mph with a "full drag" setup. Renegade YSi guys run 150-157mph all the time at 3200 raceweight.
I have pretty much been the only YSi LS1 guy running at the moment.
