Car Forum / Ford / Ford Mustang / August 2009Throttle Body Size
Can anybody tell me how to measure the throttle body on a 97 Mustang GT, 4.6L.? I am looking to put a 70 or 75 MM Throttle body-- anybody have any suggestions on what one I should go with? Engine is completely stock > Can anybody tell me how to measure the throttle body on a 97 Mustang GT, > 4.6L.?

They have to be calibrated to each other, I think. replacing just the throttle body won't do squat for you. mass air, injectors, upper and lower intakes as well as recalibrating the ecm is what has to be done in order gain any gains. >> Can anybody tell me how to measure the throttle body on a 97 Mustang GT, >> 4.6L.?

Of coarse I went even further eventually. I'm not to familiar with the 4.6l, but by doing what I suggested on my 5.0l improved the et dramatically. >> replacing just the throttle body won't do squat for you. mass air, >> injectors, upper and lower intakes as well as recalibrating the ecm is [quoted text clipped - 10 lines] >> > None of that will do squat.

NPI heads from 96-98 (some 99s?) are major bottle necks. Besides some power adders, the heads are the first and best choice for an upgrade. Trick Flows are looking pretty good to me. ;) |
