70 Mm Tb Vs. 75 Mm

[BLOWNo2]

I have an 02 SC gt with the paxton novi 1000. I want to do the accufab tb/plenum combo. is it better to go with the 75 mm for supercharged cars, or stay with 70mm? thanks!

I would think the 75 mm would be better for a blown application because it allows more flow, kinda the 'bigger is better' saying. On NA, it might hurt air velocity at lower RPMs, but I'd go with the 75mm anyway, especially since you're boosted.

Agreed.

75mm.

75mm > 70mm Hands down...ESPECIALLY since you are blown...and I am jealous...

 

[RedBullitt]

bigger is better blown

yes 75 is better for blower car. i got the 70 because it actually was supposed to be better on na, but that was a mistake, cause now im gonna get blown and i want a 75.

most people stick to 70mm for N/A and 75mm for F/I
