I am looking at doing a 75mm t/b and larger plenum in the near future and I know that accufab makes quality stuff but their combo on AM is like 425 or something close to that while the stack racing combo is only about 285. I want quality but if they are virtually the same quality product I would obviously rather save 140 dollars. Anyone have the stack racing combo for a while and what your thoughts are on it. Thanks

I'd look into the TRICK FLOW (70mm or 75mm -same price) combo (T/B + Plenum). You can get it through Summit Racing. It's between the two in price & quality. I've had no issues with mine.

The PP 70mm TB and upper plenum got me to 262/305 with minor bolt-ons and a fully tweaked tunes--read more about TBs and plenums here:

I went with the 75mm Accufab tb/plenum mainly just because i wanted a great quality brand. I really didn't do it for the looks either.

I also went with the accufab!

I have the Accufab 75mm unit as well. Looks nice when I clean it and seems to perform well.

I think most mainstream units (BBK, PP, etc) will do the job well.

I'll let you in on a little secret.....The TB/Plenum does very little if anything on a bolt-on only car. If you are supercharged/turbo'd, different story. When I put my tb/plenum on, I wanted my 20 minutes back.

Just being honest lol.

Dragon throttle bodies and plenums are on par/better than accufab, at least in the cobra world they are. And I believe they are cheaper bloom into them.

I agree, but only IF the stock tune is retained--in fact bolt-ons in general, other than opening up the exhaust, are a waste of time and money without a decent tune that bumps the timing and cleans up the pig-rich at WOT fuel mix.

I have loaded "87 octane" custom tunes onto dead stock Mustangs and never had anyone come back without a smile on their face...

This is why I'm currnetly on a mod motor hating spree, every little change has to be optimized by a tune. I'm heavily considering a 427w stroker for my car and it will be carbed.
