70mm or 75mm Throttle Body

whitehorse01 · May 12th, 2008, 08:16 PM

I'm getting a full exhaust put on this summer, mac lt's + o/r prochamber + magnapacks..I'm also gettin a JLT ram air and accufab upper plenum and SCT xcal 3..is all of this enough to gain from a 75mm TB or should I just get the 70mm???

honestly i dont think it matters but if your n/a get a 70 mm

CODEBLUE · May 12th, 2008, 09:21 PM

What gains can be made with a TB ?

03TropicGt · May 12th, 2008, 09:25 PM

id really like to get a straight answer on this to get it cleared up, what do you really need to benefit from a 75mm and how much could it actually hurt you?

whitehorse01 · May 12th, 2008, 09:39 PM

yeah..i need more of an answer to my question please!!!

whitehorse01 · May 12th, 2008, 09:39 PM

and what is n/a?

03TropicGt · May 12th, 2008, 09:44 PM

naturally aspirated, meaning no supercharger, turbo, and nitrous if you consider it n/a

Hi! I'm a newbie, but I just posted a reply on a another thread in this forum (TB & plenum flow data) that would fit right along with your question. Sorry, I would quote it but I'm not exactly sure how to do that.............

recently i put a 70 mm and a trick flow upper plenum on my 02 gt and dropped two tenths. most every where you read people claim 70mm is fine for all motor. you do not really benefit from 75mm unless you have head and cam work, or boost. in some cases 75mm may actually hurt you.

yeah I'm just aspiring to be full bolt on..no heads and cams or s/c yet..looks like ill go with the 70mm, thanks guys!

whats the difference between trick flow plenum and regular plenum? or is it just a fancy way of saying it...

Trick flow is a brand... i rocommend C&L plenum or accufab..

I heard that aftermarkit plenums only give you horsepower above 4000 rpm range..so it really doesnt benefit you to get one unless you race
