Throttle Body & Plenum + pro-m

jersey 00 GT · Jun 6, 2004

Hey, guys
I am planning to have Accufab 75mm Throttle Body & Plenum + pro-m 80mm installed on my 00' GT.
I am wondering how much horse power i can gain with these parts.
So far, i have K&N cold air, Borla exhaust and steed pulleys.

one guy gained 20rwhp and lot more rwtq with C&L 85mm MAF, Accufab 75mm TB, and C&L Plenum.

with the plenum and tb you will see around 8 rwhp. dump the pro-m and get a t/a or a midpipe. the pro m will not give you very much power and you can get alot more power with a midpipe.

Hey, guys

I was told that bigger Throttle Body & Plenum combo works better with bigger MAS, but i guess i gotta start doing a research on a midpipe.
Does midpipe make the car loud???
Also if i wanna quieter midpipe, which company would you recommend?

Thanx!

go with the tb plenum combo, but keep the stock maf. an aftermarket midpipe will make your car alot louder, but is the biggest power adder in terms of bolt ons. I have a mac o/r xpipe, i love it, but my car is very loud. do a search and you will find plenty of info on midpipes.

go with the Accufab 75mm Throttle Body & Plenum.

KJ Hoppus is right, a new MAF meter on a basically stock 99+ GT is a waste. Just my honest opinion. Save the money for something else, like the mid-pipe or gears.

who was that??
i dyno'd 255rwhp SAE with pullies, maf, intake plenum, tb, catted x pipe, cat back

Read Trinity_gt's post, he only got 5HP with Accufab TB & Combo.

Changing the MAS is a waste unless you are S/C'd.

yo jon, it was some guy with a yellow stang i believe. He also had the Pro-M remote optimizer. btw 255rwhp is not bad at all. what was your rwtq??

oh, and GEARS GEARS GEARS!

StangLou · Jun 6, 2004

Yeah I saw a link to that a few months ago. It was a yellow stang they put it all on. By they way, they spent close to $900 on all those parts for their 22hp. It wasnt simply the tb/plenum/pro m combo. If anyone can find the article feel free to post a link again.

Yet, he got 9.3 hp with his K&N FIPK. This makes me wonder if the theory is true when one says "There's only so much air you can flow to the motor with the heads, cams, and displacement being stock despite what mods you do to the intake". I think that applies here.

Hey guy

I will go with Accufab throttle body & plenum combo.
Also, does anyone have Steeda timing adjuster or Hyper tech power programmer III?
Do they really do what they say in the advertisement?
Steeda's timing adjuster - up to 10 horse
Hyper tech - more horse power + better gas milage

IS it really true???

I remember that thread now

I dyno'd 255/284 with $1550 in mods (+ $50 for pulleys install)

twogts4us · Jun 7, 2004

Accufab TB and Accufab Plenum
Steeda TA
Hypertech
Personally I think the SCT kicks azz - ck it out at www.modulardepot.com

VatStang · Jun 7, 2004

I would say 15 rwhp is likely, but it could be more because you've got other complimentary mods as well. Don't be like me...dyno it and let us know! As a test I ran my car with MAF, TB, and PLENUM. Felt good. After hearing some guys here say the MAF was crap, I took off the true flow tube and MAF, and put the stock MAF and inlet tube on. The difference was like night and day when I put those stock pieces on. The MAF will give you the throttle response that the stocker lacks. Some guys are partial to certain mods; I have never dynoed my car, but it hauls.

Thanx guys!
Now i am thinking if i should go with 70mm or 75mm

well, it depends on which plenum you are going to get? Accufab Plenum or C&L Plenum?

70 for accufab

75 for C&L

jersey 00 GT · Jun 7, 2004

Oops i thought Accufab makes both 70mm and 75mm Throttle Body & Plenum combo. I will do the resarch again
