throttle bodies......

Dino · 02-11-2000, 06:22 PM

I thought that by putting on a larger t/b, that you'd lose hp and torque unless your motor was modified. But in the Jan 2000 issue of MM&FF, they added a 70mm t/b to a 99GT and picked up 3.8 hp and 3.4 lbs-ft. Would I notice similar gains by adding a 70mm t/b to my 96 GT? Thanks!

That's a good question. If I'm not mistaken, the heads are quite a bit different (on the inside), but I'm not sure. The '99 GTs are really stout bone-stock. I'm not sure you'd see much if you haven't done any exhaust work, pulleys, etc. If I see anything in my back issues of MMFF, I'll make a post to that effect, and/or email you.

My mods right now are limited. So far I have cold air induction, Dynomax Super Turbo mufflers. Pretty soon though I'll be getting a catalytic H-pipe, pullies, gears, and lower control arms. Thanks for the info 4cammer, let me know if you find anything.

Dino,

Dug out my back issues of MMFF magazine (yeah, I'm sittin' at home on a Friday night!). In the December 1996 issue they test all of the 4.6 bolt-ons on a '96 GT. As I suspected, they got only a 1 horsepower increase with the 70mm throttle body. They say that the stock 65mm unit will be plenty sufficient unless you are going with a supercharger, then you'll need to upgrade. I say don't spend the money.

So, if you can get your hands on a December 1996 issue, you can read their results. Hope that helps.

I agree with 4cammer,
Unless you are planning on some stout engine mods, the throttle body just isn't worth the cash for 96-98 modular engines.

Thanks for the info 4cammer. My MMFF issues only go back to 98. If you or anyone else has a scanner, could you please scan and email me that article for the 4.6L Bolt-ons from the December 96 issue. Thanks!

Take it from someone that put one on, don't waste your money! I can think of a lot of other things that the $190 could have got.

hmm....i was thinking about adding a 70mm tb to my '95 GT. any suggestions on that? would there be any gains/losses? just curious cuz you guys were talkin about the 4.6 engine and mine's the 5.0. (i've already put pulley's and cat-back system on it, and i wanna put ram air kit on in about a month).

Back before this project began to spin out of control the first mod I made was a 70mm BBK TB and the MAF post removal modification. While I would agree that ther was no really noticeable HP gain it did seem to make the car breathe much better a higher RPM - seemed to make power a little higher in the RPM range - which is one of this cars problems. Stock it seemed to stop making HP after about 4600 RPM - Worth every penny if you plan to continue to Mod. as I did. Without a doubt, gears will give you the most bang for your buck right now. Good luck & keep the shiny side up!
