Drivability blower vs turbos

if your gonna have a 500 inch motor id use 2 s480s.. it will spool them just fine.. and id go 9.1 or more if i were you.. with a giant motor like that and a single s480 your backpressure in the manifolds will be triple whats going in the motor.. a good ptc or ucc converter is a must have..

guys are having zero problems spooling single s480 on sub 330 inch motors.. with a good converter spoool wont be a problem..

id get a 3.25-3.50 gear depending on your tire hieght..

if your goals are low 9s then a 340 or a 360 inch would be fine.. a 649 dollar base s475 would work fine to..
