  Gt500 throttle body upgrade kit for 07Gt

  Everything was great. Had to fab bigger holes in spacer plate. But all bolted on great. Now just waiting on CAL appointment to see how much difference the performance is

  Install is not simple

  I am pleased with the performance! I was not happy with the fact that I had to drill out the adapter/spacer plate and throttle body without a template.(The adapter/spacer that comes with the throttle body should have been predrilled. It was to fit the throttlebody...not the intake.) Also since it is a larger throttlebody...i needed a larger boot that attached the cold air intake! No mention was made from American Muscle! They also don't offer a boot that fits this throttlebody! It takes an afternoon to install IF you have all the parts and drilled out. Otherwise it will take about a week to get a proper size boot! But I am beyond pleased with the performance of this GT500 throttlebody! Much better response, better low end torque! I love it but my tires dont!

  Ford Performance GT500 Throttle Body

  Great Mods as well gain some power. Do need some drilling at back plate to fit on manifold.

  Still waiting

  I haven't installed the throttle body yet. The install does not mention the need for an adaptor to make it fit your existing cai. One should be made available through a.m. to make this an easier install.

  Great product

  Great product! My car responded well to it. Instant torque but you need an adapter for the intake to make it on the throttle body.

  Good Throttle Reaponse

  Fairly easy to install, just follow the template they give and you will have no trouble. just don't forget you will need a 5" couple to reattach your intake. I forgot to order one so my car was down for a couple days while I waited.

  Awesome

  The Gt500 throttle body was a little tough to install. Had to drill out and mill the holes on the throttle body. But overall a great investment.

  fantompony again

  UNFORTUNATELY THIS HAS TO BE A NAGATIVE REVIEW. I PUT THIS TB ON MY 06, AND THE CAR NEVER IDLED PROPERLY. WHEN I WOULD HIT THE ACCELERATOR IT WOULD HANG AT 2500 RPM. I NEVER GOT TO ACTUALLY DRIVE MY CAR EXCEPT UP THE STREET AND BACK. THIS WAS A WASTE OF MONEY FOR ME. I PICKED UP THE GMS 62MM TB AND THE CAR RUNS LIKE A CHAMP

  JUST A LITTLE BIT MORE

  The GT 500 throttle body easily replaces the stock one. With some slight modification to the unit (basically enlarging the bolt holes) it bolts right on. The folks at Bama wrote me up a new tune and we were good to go. The one thing I would mention is if you already have aftermarket breather check the diameter of the rubber boot that connects them you may also need a new boot to connect them together

  Throttle responce

  Didnt really feel a difference in performance maybe a few ponys maybe 5 if that. But did it for the throttle responce. Great for at the track cutting down those reaction times.

  Gives my Bullitt an extra boost

  I was skeptical of the gains from going from 55 - 60mm, but what a difference does it make on my 09 Bullitt (with a custom tune of course) The car is definitely snappier in the lower rpms and you feel the gains with WOT. The only downside is you have to drill holes into your throttle body to make it fit properly. Had a shop do the install for $150. Thanks American Muscle!

  Great part, tricky install

  part is great. Be sure to get an oversize boot for intake throat. It is larger than stock size and American muscle doesn't have them nor will they tell you that it is needed. You will need one that is bigger at throttle body and small enough for intake tube to work.

  Proceed with Caution 2005 GT Owners

  I purchased this throttle body to upgrade my 2005 Mustang GT. The instructions were clear and template provided; however, I overlooked considering a new CAI that would fit this aftermarket product. Upon searching for one, I could neither find a CAI for this size throttle body for my 05 GT platform; nor could I find an adapter for the GT500 throttle body and 05 Rousch CAI (which has an angle and is different in length compared with the subsequent models for which this FTB was designed. I ended up taking it off and will try to sell it on craigslist. I put the old one back on but ordered a procharger which is on its way so ultimately it is irrelevant. While it was on it sounded great, but AM should offer a CAI that is compatible with this item for 05 GT upon checkout as it (CAI) is a necessary part.

  Silicone coupling fitment

  Note that the 4-1/2" silicon coupler that currently ships with JLT Series-3 CAI will _not_ fit to the GT500 TB, which requires a 5" coupler (6.2" x 3.5") even with stretching. Some reviews have said that JLT will fit up but this is not the case.

  looks and Performance

  The throttle body is not bad American Muscle delivered it a day sooner than I thought only thing that I can say about the throttle body as a negative thing is are you also going to have to upgrade your rubber coupling that connects to the cold air intake to the throttle body it will not fit it is an inch and a half off so on your rubber coupling you will need to go by A 5 inch on one side and 5 and a half inches on the other side you will have to look online to order it could not find it nowhere else because it is too big that and the throttle body does not line up with the hose on a Ford Racing intake manifold you have to grind out hold out a little wider for it to match up but just the only one hold but it did create a better for throttle response then with the Ford Racing intake manifold it is breathing a whole lot better

  Not for Whipple Supercharged Applications

  First, this would have received all 5s if it worked on my car. However, not listed on this site, but found elsewhere this item DOES NOT fit those cars with the Whipple 2.3L (140ax) Supercharger. The 180* inlet doesnt have enough tolerance between the S/C housing and the inlet to allow it to fit. The TB physically cannot fit on the inlet. AM did a great job in RMA and I've since purchased the FRPP 62mm one... Just a word to the wise for those with the Whipple S/C

  Shelby GT500 Ford Racing Throttle Body with Adpater Plate

  My car is a 2006 Mustang GT. I installed this Shelby GT500 Throttle Body with Adapter Plate ( already correctly machined for correct fit ) in about 25 minutes and it is a true bolt on, plug in, and go part ! Excellent fit and finish and looks great in place of the stock throttle body. I also installed the Airiad Race CAI along with the SCT Bama Tuner and installed the performance tune ( it's idiot proof ) by simply following the screen prompts. This is the best combo of parts along with the tune to get the most bang for you hard earned dollars outside of getting into new heads, cams, or a turbocharger. I would recommend these parts and tuner to everyone with a 4.6L 3V engine. More sensitive throttle response and no lag between shifts in my automatic and it wants to spin the tires even with the TCB on and not even at WOT ! Best money I have spent for performance yet and I am still acquiring other parts for future install and tuner upgrade as well.

  Not a big improvement in performance.

  Ok let's talk about the sales pitch. To be honest all this part even though it's larger has done is bolt onto the original intake manifold which reduces the TB size back down to stock. And I would recommend that you change the intake too. Unfortunately once you drill the huge holes in the GT500 TB you have ruined your part. The nice cover I have on top of the motor had to be modified too. I hated to hack up brand new parts. I am a master craftsman in the best Aerospace company in the world so this was very simple to do. I did notice a small boost in performance. Just didn't like to modify new parts. I used the adapter plate as a template and had a 1/2 inch counterbore bit used in the sheet metal fabrication industry manufacturer is Craig tools. Made for a perfect match on installation. You will need to heat the rubber sleeve on your existing cold air intake in boiling water to stretch it over the larger new TB. I knotched the stock decorative cover and slid it behind the top mouts on the new TB. I will attach pics to show the bit and how I clamped the adapter plate in place.

  GT500 Throttle Body

  I purchased a used GT500 throttle body and purchased the adapter plate new. Modifying the throttle body is easy took about 10 minutes to drill the holes. It took a buddy and me less than three hours to install my lowering springs, pan hard bar, and throttle body. I did purchase the new larger Silicone adapter to fit the throttle body and intake. I'm running a Spectre intake so I had to cut the spectre silicone adapter to take up the extra room since the oversize adapter is too large for the round intake. Overall good performance gain. I can really hear the intake sucking now. I am impressed with this mod!!
