true?

Blk01ponyGT · August 16th, 2007, 01:13 AM

ive heard that N/A with a CAI that a TB and plenum is worthless and really could hurt you more than help you? i heard it from a really reliable source thats been workin on mustangs for ever...it just seems weird to me

energiesource · August 16th, 2007, 01:15 AM

if you have a stock engine with a 75mm tb and plenum with a cai, then it really wont do anything for hp wise, but to hurt it, never heard that

HMUSN · August 16th, 2007, 01:15 AM

false.

75mm can hurt you
but a 70mm won't

it's not going to see big gains on a n/a motor though

Saleenwolf720 · August 16th, 2007, 01:18 AM

I've heard that putting to large of a TB on a car that is more or less stock will hurt performance. Thats probably what your source was talkin about.

mattstang · August 16th, 2007, 01:26 AM

what if your on the bottle and see the strip eventually but otherwise stock

Hunt_chevs · August 16th, 2007, 01:31 AM

i got a 99,.. i put a bbk 75mm tb/plenum combo, flows, and a fenderwell, aside from my tri-ax thats all i have... and i definitely notice a difference...powerband hits a lil diff. (a lil later) but it pulls harder than stock... my boys got a 02 and he used to take me all day wen i was stock,.. but even when my shifting is worse than his, im always pulling....just my 2 cents

Hunt_chevs · August 16th, 2007, 01:34 AM

nuthin gigantic,... but a difference,.. id say it was worth the 3hundo on he plenum/tb combo

2000stangGT · August 16th, 2007, 02:00 AM

i cant see how those mods could hurt you. they will give you gains but minimal. maybe 10 rwhp on avg.

i went with 75mm and havent had any problems.

every forum you see has a different response for that question lol.

04GTAMPA · August 16th, 2007, 09:52 AM

The only difference I noticed with my 75mm is that it is a little "touchy" to the response. Can get you to jerk a little more. 75mm will help with more aggressive mods, but with just CAI, it won't hurt the engine, it just kills a bit of low end.

MATT02GT · August 16th, 2007, 09:58 AM

I had a decent noticeable difference with the combo. Alot better throttle response too.

neckbonekat · August 16th, 2007, 02:57 PM

Maybe he meant that you'd take in more air than the stock headers and 2 1/4" exhaust can pass. I don't know if it will hurt you, but you won't see much gains from it.
