what size throttle body will i get the best results from70 or 75 mm? i was also thinking about getting a pleunum, which would be best deal for the buck. They all say the same but what do you think is the best. One more thing i noticed is that all the plenum are made for a 75 mm throttle body, will a 70 mm throttle body work with that or do i need to find the same size plenum opening.

news mods coming this week steeda underdrive pullies, and mac prochamber

thanks bro there was alot of good stuff there and basically they are all about the same. So i went with the c & l plenum with the mac 70 mm throttle body.
by next week my prochamber, underdrive pullies and plenum w/70 mm throttle body will be on the car. that should be a nice little extra jump with what i already got

So what's the verdict ?

Greg;

I'm in the same boat you were -- did the 70 mm TB and plenum make a sizeable difference in your response and give you a SOTP boost ?

well honestly, first i went with the c & l plenum and 70 mm tb. I went with that because there is another car just like mine and he was able to run 13.46 in the 1/4 mile with the same bolt ons. so i did and a few people did say that bigger is not always better. and i have stock cam and heads so there was no need for the bigger tb. as far as feeling the difference not really to be honest. but i believe it has helped with tb response and that was what i was basically looking for. i hope that helps. as far as true horsepower to the wheel that set up is like 6 horsepower together. i got my car dynoed like 2 weeks ago and i thought i woulda been a little better than it was but dynos don't lie. hope that helps and let me know if i can help u another way

Trick Flow's plenum is about 20 bucks cheaper than the C&L. As for them all being specifically designed for a 75 mm tbody, I believe actually the accufab is designed for a 70mm, but will work with a 75 mm. Mac has a polished plenum out now, sells for about 179 and looks like a polished C&L. Real pretty! The 75 mm tbody is supposed to net you about 2 more hp, which you can't even feel, and that is a lot more money for a little bit more hp that you can't feel.

I have been running C&L mafs on my GT and my V6 before that, its a good piece, gives you a great hp boost for the money. Pro M does their own electronics, and they aren't known for being consistent at all, C&L uses the Ford electronics, can't get any better than that. I am completely satisfied and my idle is fine. Always has been. :lol:

I know I wish I bought my c&l instead of pro-m. I think mine is defective. :disgust:
