      Review & Installation Video

      Hey, guys, it's Joe from AmericanMuscle. And today, we're gonna be taking a closer look at the SR Performance 62-millimeter twin throttle body, fitting all '05 to '10 3-valve GTs. Now, this is gonna be the perfect option for you if you're looking for a solid supporting mod that's gonna add a little bit of horsepower by freeing up the airflow just a little bit at a reasonable price.So, what do we have going on here from SR Performance? Well, first thing's first, bigger diameter bore on the throttle body, twin 62s going off from twin 65s, that's going to allow you to push a bigger volume of air through the throttle body, and in theory, eliminating a little bit of the restriction that the throttle body may hold. This guy is made out of 356 aluminum, just like the factory stuff. Speaking about factory stuff, you can also see that this lip here is nailed down to the factory size, and that's going to allow you to retain your factory intake. If you have any cold air intakes and you have them attached to the factory throttle body, those, in theory, should also work.To run this, there's no tune required, again, just drops right in place of that factory throttle body. One thing I do wanna note, as you can see, there are no electronics on the sides here, we will be transferring those over from our old throttle body. So, if for any reason those don't work on your factory throttle body, you will need to pick those up in order to run something like this. We're gonna show you how to transfer those over in just a second.So, now let's talk a little bit about horsepower numbers. I'd call this right here a supporting mod. If this is the only thing you have done your 3-valve, you're not gonna be taking down any Z06s, Hellcats, or Vipers, that is for sure. But if you have a bolt-up 3-valve that's just missing a throttle body, SR claims 15 to 20 horsepower, 20 to 25 torque at the rear wheels. If you're going for that bolt-up build, you're looking for the last piece to put it over the edge, you think you're throttle body might be a restriction on airflow, this is gonna be a great budget-friendly option. However, as a first mod, you probably won't feel any gains from a good old butt dyno.Pricing for this throttle body, gonna drop in right around 300 bucks, definitely more toward the budget-friendly side. Again, if you have that bolt-on 3-valve, this is all you're missing, this is a no-brainer as far as the next mod goes. Install is gonna be relatively simple, like I said earlier, no tunes. We are gonna be swapping over the electronics, again, we'll show you how that works in just a second. Easy two out of three wrenches on our difficulty meter, should take you, at most, about two to three hours in the driveway with nothing but a basic set of hand tools. So, without any further ado, let me show you what tools you'll need and how it's done.Tools we used for this install are going to include an impact, few extensions, ratchets, T20 Torx bit, 5-millimeter Allen key, 8 and 10-millimeter sockets, as well as a flat-head screwdriver.Now, we can actually start work on our throttle body. First thing's first though, we're gonna continue by disconnecting the electronics, you need to slide these red clips back, and push down on the release tab, and they should pull right off. Now, we can actually get this off of our intake. And what we're gonna do is use an 8-millimeter socket to remove these two guys up here. You wanna be gentle with these as it looks like they're just threaded into plastic, and you really don't wanna mess up those threads. So, we're gonna go old school with the ratchet. We're just gonna switch over to the 10-millimeter socket, and we're gonna put this small extension to use, and we're gonna get the bottom two here. That's a nut, but you should be able to get to it just fine. Have the other one off. Now, we're just gonna pull the throttle body away. And there's actually a nice insert here, so you don't really have to worry about the threads, you could use an impact to get those out if you wanted to.So, now that we have our factory throttle body off of our 3-valve, I figure now would be the perfect time to sit it down next to our SR throttle body, point out some key differences between the two, and basically, what is gonna make this a little bit better than that old factory throttle body. Now, obviously, with the two next to each other, really really small differences, they're both made out of aluminum, they both feature that twin butterfly valve design, they're both gonna fit that factory intake and filter, you can see this milled edge here is designed to allow that to happen. The only, and really, the biggest difference between these two, it's gonna be the diameter of each of the bores, 55 for a stock one, 62 with our SR Performance. And having a larger diameter is going to allow you to push, exponentially, more air through. So, if you have a restriction in your throttle body, the 62-millimeter SR Performance twin throttle body will definitely help you out.So, without any further ado, couple things I wanna go over here. If this seal came off with your throttle body, we're gonna go put that back into the intake manifold when we go back to the Mustang. And the new SR doesn't come with any electronics, so we're gonna use a Torx bit to transfer over, basically, this guy right here, and this guy on the other side to allow this thing to open and close when we press down on the throttle.So, we're just gonna take a T20, I have mine on a ratchet just to speed things up a little bit. We're gonna loosen up a bunch of these T20 bolts here just to get the electronics off. All right. So, that's one. Surprisingly, little bit tough to turn, you can see there's a little bit of Loctite on there, and these threads are really fine. We're just gonna slowly do that same thing for the rest of the T20s on here as well.Now, I'm gonna bring out the air ratchet just to speed things up just a little bit more. That is gonna pop off just like so. And there's a little bit of a seal in here as well just like the other one I pointed out. If that pops out at all for you, just push it right back into it's cutout so it makes a nice seal or our new throttle body.So, now, in order to transfer this over, we're gonna need that spring. It has that little catch there on the end, this is just gonna go on this gear right here, and that catch is gonna sit in a hole on this piece of the gearing in the throttle body. Now, on top of that, we do have two teeth, you can see the larger one on this side, smaller one on this side, those need to mate up with the cutouts in this portion. So, as we put this on, we're gonna make sure those are seated, and then we're gonna twist this in place so we can lock it in with those T20 bolts from earlier. And we're gonna do the same thing over on the other side for our position sensor. And we're just gonna put that into the same exact spot on our new throttle body.After that, we have everything we need transferred over, so we're just gonna grab our throttle body and head back to the Mustang, we're gonna need a few more things as well. These two bolts right here, they take a 5-millimeter Allen key, I have that right here, we're gonna take that with us as well, as well as that seal that came off with our old throttle body, we're just gonna plop that back in place, and then we'll be good to install this. I'm gonna start off with our seal, just gonna work that in. And after that, gonna make sure everything is out of the way. We're just gonna come in and get our new throttle body seated on those bottom studs, and then we're gonna start that new hardware on top, and then tighten all this up. For the bottom, we're just going to reinstall those two 10-millimeter nuts we removed from earlier.Now, we have our new throttle body pretty much installed, the rest of this is just gonna be the rebuild portion, we're just gonna plug in our electronics, and then we can put the intake back on. Now that we have this in place, we're just gonna tighten back down our clamp, you could use the 8-millimeter socket or a flat-head, and then we could reinstall our breather hose, that's just gonna click right into place. Now we're just gonna lock back down the airbox with the 10-mill, and we're gonna call this one a wrap after we plug in the MAF sensor.Guys, that is gonna do it for me, it's also gonna do it for the SR Performance 62-millimeter twin throttle body, fitting all '05 to '10 3-valve GTs. Thank you guys so much for watching, subscribe for more like this one. Keep it right here at AmericanMuscle for all things Mustang.

        Not as easy as it says or shown!

        Installing the throttle body can be tricky, I do recommend having professional help, because one misstep and your car will go into limp mode which will basically put your car into a coma and your gonna have to seek either a dealership or your personal mechanic to help you fix your car! You’ll most likely be spending over $100 if you mess up the tps voltage or throttle body motor! And you will wind up spending money not only on the throttle body! So make sure your prepared for the worst when installing this throttle body!

        Video Issue

        Why make such an elaborate video and not show how to install the TPS, notice the video jumps right to being put on when it is taken off the old one ???? Noticed on the reviews that there is a lot of TPS issues, Is that why the video was cut short ? Also why was the car NOT started in Video, really making such a great video and cutting the steps that would sell the part more easily is kind of a waste. Just my opinion

        Definitely happy with this over the stock throttle body. Noticable gains and a little whistle on acceleration as a handy reminder. Install was pretty simple.

        Not Recommended!!

        Bought this in May 2018, installed in June 2018, it has NEVER run correctly. Tried new tunes, took it to a reputable shop who adjusted, retuned, and tried their magic. NOTHING! Still ran poorly, idle flares, CEL's, "LIMP" mode. Eventually installed a stock 13-14 Ford GT500 throttlebody, tuned it, runs like top! Haven't had an issue since! Move on, spend the money for a Ford Performance TB.

        Great product and an easy install!

        My four-year-old daughter and nine-year-old son helped me replace the factory throttle body with the 62 mm SR performance one. I transferred over the sensors but they did the rest. Had a great time with the kids and loving the improvement to my 2008 Mustang GT

        I had the same problem all of you are having. The car would rev up and down all by itself and then would want to stall. 1. Make sure the spring is wound up. 2. Check tps voltage. My stock tps was 1.22. I would set at that but then would go to 1.23. I had to actually set it at 1.21 and it fixed itself. 3. Once installed, start car and let idle until fully warmed up with no accessories on including ac, radio, lights, etc. Once warmed up completely to operating temps, turn the ac on and let it run for another 10 minutes. This relearned the TB. Take a it for a few drives and drive like a normal person without hard accelerating and let the car slow itself down to stops without putting the clutch in. After this I was able to drive the car without any idling problems.

      5 Top Rated Questions

      Can you please explain why this throttle body does not require a tune, but the Ford Performance 62mm throttle body says that it does? Does this really provide the same performance gains as the Ford Performance throttle body with a tune, or not?

      • The SR Performance 62mm Twin Throttle Body will reuse the OEM throttle actuator and TPS sensor, wheras the Ford Perfomance will utilize new electronics, which do require a tune. This makes it more expensive, but easier to setup with no need to measure TPS voltage or make adjustments.

      Helpful (6)

      Installation went good, car runs better can tell small difference. But I was wondering what I could do about the rpm's staying up while shifting gears? When I push the clutch in the rpm's tend to wanna stay up.

      • A hanging idle between gears could be cause by several things when installing the SR Performance 62mm Twin Throttle Body. The most common cause is the TPS voltage set higher than OEM.

      Helpful (5)

      Pardon my ignorance, but when you advertise SR Performance Twin 62mm throttle body, does that mean each of the bores is 62mm making a total of 124mm? I need clarification on 62mm twin trottle body - does that mean 124mm overall combined because each bore is 62mm; or does it mean that each bore is 32mm and the overall is 62mm combined?

      • Each bore is 62mm

      Is the opening compatible with aftermarket CAI's such as K&N? Would like to retain the K&N system as is. Does it fit this throttle body or will it require stretching like the BBK or replacement?

      • I had installed the K&N CAI prior to installing this throttle body and reconnecting it to the SR throttle body was just as easy as the initial install of the CAI system in the first place.

      Is this compatible with the SR Performance throttle body spacer (Item # 80306)? I have seen this question answered with a yes and a no? I just wanted to clarify.

      • The SR Performance 62mm twin throttle body will not work with the SR Performance throttle body spacer as the spacer is designed to work with the factory throttle body only.
