Throttle Body CFM requirements

foxbodymuscle · 09-23-2008

I am looking to buy a new throttle body but dont know what size to buy. I purchased a vortech v-1 (6psi 1000CFM) and i was looking at flow rates for the TB.

65 MM - 664 CFM
70 MM - 787 CFM
70 MM - 896 CFM (Race version)
75 MM - 924 CFM
75 MM - 1045 CFM (Race version)
80 MM - 1142 CFM

Can I get away with a 70mm, I would do 75mm but thats alot of grinding to do on the stock intake.

Thanks for the advice!

The 70mm would be plenty.
