Does anyone know if anyone has a throttle body out for the GT500. The one we have could be refined more, not sure what performance gains a polished and larger model would do but it couldn't hurt.

Thank you for the info, I will have to add this to my list also, throttle bodies are a very straight forward and simple install for the most part. Ifanyone gets this anytime soon please post up your thoughts.

The only one I have seen was from Kenne Bell, only problem is that it will not fit the oem only his SC. I asked them if there was any kind of adapter for it to work with the oem but they said no.

Whoa.

You guys are really behind the times.

L&M Performance and VMP tuning have the two best-performing units on the market.

http://www.vmptuning.com/store/index.php?p=product&id=298&parent=88

Lethal also carries the VMP unit.

LM does NOT require a PCM recalibration and has seen 15+ RWHP gains on simple upper-pulley only cars; of course more with bigger blowers and other supporting mods.

Call Matt @ Lethal and he'll give you all the details and search around, there are dyno sheets for it on several other sites (www.svtperformance.com)

And btw, someone posted a link to RPM Outlet. Please, take heed and stay away if at all possible. We have too many other dedicated vendors.

Not to start a throttle body battle here, but one of those TB's is $605.00 and the other is $499.99 and requires tuning (mo money).

The one I mentioned above offers the same performance gains, requires no tuning and retails for $285.00 less than one & $180.00 less than the other.

Is there really a $180-$285 difference between the 3?

Lets see some dyno graphs of the BBK unit. I like VMP and theirs is worth the money and if you purchased your GT500 Tuning from VMP, an updated throttle body tune is no charge. And are you serious about no tunning needed for your unit??? If your unit is designed to increase airflow you are going to need a tune or you will be running too lean.

I kinda thought the same thing, but then I figured, "What the hell do I know?" :rofl::rofl::rofl:

Exactly....I wonder why the VMP unit requires a PCM recalibration and the L&M doesn't?

I am using the VMP 67 MM TB on my car with a tune. It seems to be pretty good as far as power and drivability. No complaints about this throttle body. How does it compare to the L and M TB? I do not know. It seems to be vodo or polictically incorrect when you compare these two TB's. I have never seem dyno charts comparing the two. One may be better than the other, but you get good results no matter which one you choose.

Horsepower wise on a stock blower I estimate 8 to 12.

I'll post the TB graph on Monday when I get back tot he office.

Simply put, the MAF will calculate for the change that the throttle body offers.

Not sure why any tuning would be needed on one of the late model Ford TB's. Your average handheld tuner doesn't address anything in the TB circuits or have any options to do so as far as I know.

The only reason I can see would be to either sell a tune, (sure yo get more from a good tune anyways so why not) or due to problems that the manufacturer of the throttle body has run into and cant get right.

I went through hell trying to figure out how the DBW TB's work.

I went at it alone in early 04 on the GT's. I must've spent 3 days figuring out what the computer wanted to see and how it used the part-open function. I even had to custom engineer the brass plunger to make sure it was right.

Yes, I'm serious about it not having to have any specific TB parameters changed from stock.

You don't *have* to retune in most cases simply because the MAF transfer functions take care of the slight increase in airflow. MAF see's more air; adds more fuel; problem solved. This is based on your fuel system being capable of keeping up with the added HP (so if you're maxed out and don't have any capacity for 'excess' fuel delivery; yeah you can go lean. This would only be the case if you weren't planning ahead with your injectors/pumps and trying to do too much on the stock fuel system anyway. Consult your tuner accordingly.)

VMP and LM are on top of each other performance wise with only a *very* slight nod going to LM.

The FRPP CobraJet is made by Accufab. Both VMP and LM make significantly better power all the way through and at peak compared to it.

Call LethalPerformance or Evolution; either can provide you with better details.

Of course, running a TVS or TwinScrew you'll see larger gains with a TB than just a bolt on car, though any pullied/bolt on car will see nice gains.

(btw, I'm just a consumer; no affiliation to any shop or brand. I bought the LM based on results and perceived quality and reputation of the guys that developed it).
