help on my new throttle body!!

GTracing08 · 04-13-2009

I have a 2000 mustang gt and it just has a cold air intake and a flowmaster exhaust would putting a 75mm throttle body be to much on my new upper intake plenum or should i go with a 70mm one.

usual rule of thumb is 70mm for mild bolt ons/ normally aspirated and 75mm for forced induction or some serious head/cam/nitrous work.

What he said, go with 70 unless you plan to run it on nitrous or boost soon.

I think a set of gears 3.73 or 4.10 will be better than that you will get 5hp for the most...

The gears may do more for get up and go but the throttle body will help a ton with throttle response and getting more oomph in the lower RPMs. Not to mention a bit of help with gas mileage.

I think there's no way you can have more hp and save more fuel that's kinda ironic... Just my thoughts..

This thread makes me wonder if a tb would be a worth it mod.. im doin my gears this weekend (3.73) so hopefully they will keep me happy for a little bit..

^IF they would be cheaper maybe but they're very expensive if you plant to have a car with a lot of horsepower yeah its worth it.. but a bolt on is a bolt on so if you have the money go ahead.. but for me that would be the one of the last things to do there's a lot more things you can do that will give you more gains for the $$$..

Definitely with the pi swap will get you a lot of hp I recommend to do it but don't know how much it costs... don't forget the tune, a cam too, long tube headers (expensive too)
