Whats up everyone, I have a 96 gt that I want to improve a lil, and I have a question about Throttle Bodies. I see sizes from 70mm, to 78mm, and I've heard that unless your engine is really built up that it's actually hurtful to get the bigger throttle bodies (75mm and up) Thoughts?

Some info about my car: CAI, slp Loudmouth 2 cat back, & PI intake manifold.

[96_gt_stanger]

Sorry if its a stupid question... but I looked around with search I swear! Just want to get some professional opinions

[HMUSN]

the general is to go for a 70mm if planing to stay N/A and a 75mm if using forced induction.

[BizCutt]

it doesnt matter how big it is..the plenum will be the restrictor once you go over stock size...for the maoney you get some headers...which are a huge pain in the ace....or some juice...soemthing worth the 3or4 bills....


!!!!!!!!!!!!!!!!DONT GET BBK...THEY SUCK WORSE THAN STOCK!!!!!!!!!!!!!!!!!!!!!!!

[ModMustang97GT]

The 75 or the 70 will be better than stock. On a stock engine the 75 actually flows slightly less than the 70 because the stock engine can't pull in enough air, so the larger inlet causes the air to stall on its way in to the engine. Also, you should do the plenum at the same time, as it is what the air goes in to directly after the TB. And if you open the TB but not the plenum. you are helping the air flow but not by as much as with the new plenum. As for the FI, no FI uses a 75mm TB. Its not enough for FI, you usually move to a 90mm with FI. Only the crappy FI paxton and vortech kits use the stock TB. The 75mm is generally for Nitrous cars and heavily modified N/A cars. Stroker 11.5:1 7.5k rpm kind of cars. Its better than stock by a long shot, but your not going to be using it to its potential any time soon without nitrous or some stroking and worked heads/cams.

Are you sure you are not talking about a 90mm maf? Do you have a link for the 90mm 2V tb?

As far as power gains on a nearly stock Na car, i would save your money.

[96_gt_stanger]

Thanks for all the replies everyone! I really want to add something that will be beneficial to my car, and it sounds like a new throttle body isn't needed yet... I'm guessing when I get the money, either an x-pipe, cams, or the dreaded.... heads! It sounds like after that a throttle body would be more logical to buy.


Btw, has anyone heard of this new BBK Throttle Intake thing? It's different than a normal plenum and throttle body, its kinda like they combined it and made it 78mm. Direct Bolt on! BBK 78mm Mustang Throttle Intake (96-04 GT) at AmericanMuscle.com - Free Shipping!
just figured I'd put it out there.

[BizCutt]

!!!!!!!!!!!!!!!!!!!BBK SUCKS ACE!!!!!!!!!!!!!!!!!!!! Dont do it....if you plan on making any kinda power....

[96_gt_stanger]

Bizcutt do you have any facts to back that up, or are you just ranting..

just about every thread i see him in is "DONT GET BBK IT SUCKS ACE!!" id like to see some facts because i have shit tons of bbk and i have no problem with 5 at the rear wheels.

[DeMello]

OP....not worth it to get a t/b and plenum yet

spend the money on something else like gears

[Ryan Paymaster]

Throttle body is such a minute gain that it should be purchased last. You'll be throwing down $350-$500 on a small horsepower gain. My opinion is use that cash, buy some headers and have them installed.

I think BizCutt said he cracked a BBK putting down power. I've read claims that the BBK actually puts on negative horsepower. Facts? I dunno, just forum posts that I've grazed through over the years.

General thought around 4v is that the best throttle body is made by Accufab. I know GT owners have other options out there, a notable one probably being C&L.

Personally I'd go with Accufab or C&L, but that's your choice. I stick to BBK for reasonably priced headers.

[BizCutt]

!!!!!!!!!!!!!!!!!!BBK SUCKS ACE!!!!!!!!!!!!!!!!! You will see this until they prove to me other wise....generic sheet....
This might be a bit lengthy...but you want facts...here ya go emails and a pic....

Welcome to BBK, home of the OEM performance part. We hope your product doesnt break cause we dont offer a reasonable solution....

[96_gt_stanger]

That pic is a pretty good form of evidence haha. Ya I think I'm just gonna go with something else for power at this point like some ppl are sayin i should. Glad I didn't waste the money on something that would give me hardly any power.

[BizCutt]

!!!!!!!!!!!!!!!!!!BBK SUCKS ACE!!!!!!!!!!!!!!!!! You will see this until they prove to me other wise....generic sheet....
This might be a bit lengthy...but you want facts...here ya go email and a pic.... this is just the last of my dealings with them...dont get me started about the header and h pipe coatings and fitment....thats another post in itself....BBK SUCKS ACE

Welcome to BBK, home of the OEM performance part. We hope your product doesnt break cause we dont offer a reasonable solution....


this email starts at the end of or chatting the beginnig is at the bottom...start there and work your way up.....

This guys an idiot as you will read...HE'S there yes man and defense attorney on the net...also THERE WD COST FOR THE STOCK REPLACEMENT PIECE WAS $325... MORE THAN I COULD BUY A BRAND NEW ACCUFAB WITH THE BILLET THROAT...Accufab has been hold ing just fine the last few months...no complaints at all...BBK SUCKS ACE!!!!!!!!!!!!!!!!


There are 2 possible solutions to this issue.



We can sell you a replacement unit at W.D. cost.
Or

We can make a unit specifically for you where we leave a little more material around the lip area. For this you will need to pre-pay for the unit (again W.D. price) and wait until the 1711/1705 throttle bodies go into a production run again. The CNC shop will not be able to go off schedule to make 1 unit as it takes about 8 hours to set-up the machines for each part we run.


Keep in mind that no matter how thick or what material is used, T-bolt clamps will put all of the clamping force on the “ends” of an oval TB lip and not equally and evenly around the entire lip like on a round TB.



A worm drive clamp would be more appropriate for the application (even if the T-bolt clamp came with your turbo kit).



Also keep in mind that just because there are threads left in the clamp and “it could tighten more”, does not mean that you haven’t over tightened it for the item it’s gripping. A T-bolt clamp can easily crush things like exhaust tubes, throttle body lips, or anything else you use them on.



Consider this; 16psi is the same pressure that the average cooling system uses and you don’t see anything more from the factory than a worm drive, or Fords “auto clamps” that don’t even have a drive. The ones Ford uses are reverse spring loaded.

I didnt hear from you? How are we going to resolve this? Do I need to buy one from a company that can support the power, and provide you with plenty of internet exsposure? Are you guys capable of suppling an item that will with stand the rigors, or if not a refund of sorts for a faulty design?



Thanks again



Tom
