Will a 75mm Mass Air work with a 70mm Throttle Body?

Mack Daddy · 08-08-2003

Im looking to puchase a 70mm BBK Throttle body soon and I want to know if I purchase a 75mm Mass Air unit that it will work together fine??

Sure will, as long as its calibrated correctly.

Im keeping the same MAF im just looking for a bigger unit. I didnt want a restriction problem....

Yep, that'll be fine. The 70mm tb is the perfect match for your GT40 intake.

ok, thanks everyone.

yes even the c/l 76mm will work but that 70 T/B is a lil big unless there has been many engine upgrades

No, it's not. As long as the tb is no larger than the intake opening it won't hurt power. Throttle response can theoretically be slightly worse with a larger tb, but usually not noticable.

I beg to differ...on his combo a 65 will yeild better throttle reponse and better low/ mid-range hp..the 70 might will lose 3-6 hp in the area but might gain 1-2 hp in the 4000-5500 range...with the 95's a c/l 76mm might work as long as you clock the maf those 94-95 computer are something else
