TB and Plenum

OhhShorty · January 14th, 2008, 12:33 PM

I have no clue what the difference is between the 70mm and th 75mm.. can someone please clue me in and help me figure out which one would be best for my '02 Stang

whtpny · January 14th, 2008, 01:10 PM

the 75mm has more potential to flow in the long run obviously but it all depends on what your goals for your car is.. alot of ppl will say that 70mm is good enough though.. fill us in on ur ideas

They don't add much to a n/a motor. I've read independent test that say 2-3 rwhp. But, if you buy one I'd go with the 75mm TB/Plenum. If you buy a centrifical supercharger or turbo later they get you 18-20 rwhp.

and for an n/a with n2o?

I always use the 70MM Accufab products on NA setups and have had nothing but good luck with their products.

Sorry I've been gone for a while.. But my plans is to eventually get the 'Vert to at least 400rwhp with bolt-on mods and a turbo..

75...if your planing turbo

ModMustang97GT · January 31st, 2008, 01:06 PM

If you have aftermarket heads and cam, go 75 otherwise go 70. The 75 actually flows less air on a stock engine, because it is too large. The Air flow stalls on its way in to the engine so it actually flows less than the 70mm. On a modded engine, it will flow more than the 70mm. Either way, they both outflow the stock one by something like 50%, so its going to be worth it.

If your planning turbo, get a dual 65mm or a 90mm. FI requires WAY more air than any n/a.

75mm is just simply THE WAY to go. which one of us owns a mustang and have left it somewhat stock. i have a 75mm on my 03 GT and it runs great man. not many of us can simply own a stock GT. sooner or later that itch begins and you cant help yourself.
