what size throttle body ?

cobtc · November 20th, 2008, 04:25 PM

my 90" GT is bone stock. i'm buying parts for my build now. what size TB is recommended for making 260 to 300hp ? (i am using a cobra intake.) thanks

A cobra intake is 70mm, so you realy dont need to go bigger than that if you never plan on changing to a bigger intake.

93mustank · November 20th, 2008, 04:29 PM

Fine with a 65 mm

uprpat · November 20th, 2008, 04:34 PM

70mm

flamestang · November 20th, 2008, 04:35 PM

I recomend 65 or 70 runs beter if TB smaller than MAF

1FastFox · November 20th, 2008, 04:44 PM

So get the cobra intake, 70mm TB, and C&Ls 76mm mass air and elbow combo...

flamestang · November 20th, 2008, 04:50 PM

ya C&L kicks ass I had that combo and ran great

Haggis13 · November 20th, 2008, 05:02 PM

65 for mild setup.

70mm in 94 and 95. I dont know about modular ones.

If you want close to 300 rear wheel hp then those stock injectors arent enough, step up to 24s with calibrated MAF. Heres a good chart from Darrells archives, those are flywheel hp.

dont get any bigger than a 65 i guarantee you make more rwhp with a 65 than a 70. guarantee

Thats a bold statement, is this based off of hard data, personal experience or myth?

+1

i would go either 65-70mm depending on supporting mods

tgk · November 21st, 2008, 01:08 PM

No need to go above 65 for that power level.

I've got a 65mm Professional products throttle body that was ran for about 2000 miles. Still got box and all. $75 shipped. Pm if youir interested.

flamestang · November 21st, 2008, 01:49 PM

If your running a 302 with mild boltons(n/a) you want need more than 65mm If you plan for more in the future get a 70mm

He would be referring to "viscosity" and i'd have to agree with him.

With that mild of a build i'd go with the 65mm tb and a proflow 75mm or larger calibrated for your injectors. If you think you'll be in the 290 or 300hp neigbhorhood which is the end of the stock 19lb injectors then go with the 24s and get a 75 or 77 proflow calibrated for them. I've ran a cl meter before and had nothing but problems with it.. ran another on another car and it worked ok but never had a problem with prom/proflow meters which is why I suggested them. Could always pickup a cobra 70mm off ebay for like $50 to run with your stock injectors also

TKOTLARZ · November 21st, 2008, 04:14 PM

look if u plan on getting heads and a manifold get the 70 mm t/b instead of buying a 65 and have to get a bigger one wen u buy the heads..no point in buying the same part twice..u need to set a plan and know what ur gonna do so u can buy the right part the first time..

I was looking for an educated reply, not a sarcastic unintelligent remark.

BTW according to some interweb reading the world is going to end in 2012.
Will it? probablly not

Will a 65mm make more power than a 70mm? probably not.

I suggest you get off the interweb once in a while and go experience the real world. Cause as of right now I dont know of anybody who is taking off their 70 or 75mm units and replacing them with 65mm. I guess I could be wrong especiallly if it comes with a guarantee from grnstang.

Well i better go I need to swap out my 70mm tbody today its to big and I heard on the internet a 65mm is gaurantueed to make more power.
