that should have been .5
> 
> VE can be from .7 up to 1.25 depending on your tuning setup
> average VE is int the .85 range street car
> 1-1.1 range well tuned race car 
> 1.2 + range indy/cart/ etc.
> 
> estimate 11-1200^ ex temp for well tuned street car
> 13-1400^ for race
> 13-1700^ for turbo setup
> 
> optimum is flow rates in the 225 -300 ft/s range
> 
> calculate flow rates from cyl volume/header volume
