Coyote guys - has anyone swapped out for a larger 85mm throttle body?

BBK MUSTANG GT 85MM THROTTLE BODY ASSEMBLY

yes, it's 10-12HP gain, and 10 ft-lbs

not that anyone 'needs' more power, but because you 'can' add more

Stock throttle body is 80mm for both Gen 2 and Gen 3 Coyote (2015-2020). The GT350 has an 87mm throttle body. With careful tuning and a bolt-on adapter (bolt holes are spaced differently), you can use a GT350 throttle body on any 5.0L Coyote intake. The BBK 85mm is popular too, and seems to work better right out of the box than the GT350 one. There are others, too, but the idle quality will suffer if you go too large here. The ECU tries to meter a small amount of air in, but a small movement of a huge throttle blade will allow a big gulp of air to come in, so getting that idle and low throttle tuning just perfect is critical.

understood, I hear headaches from the 90mm crowd - but 85 seems to brighten the pedal and add some oomph...

assuming this would be dyno tuned, the ECU can be tweaked to allow for the extra air

I'm guessing whatever you're hearing is from the Mustang crowd. Who are dragging around a bunch more weight and the slight added power might be noticeable. Have you actually driven one of these? I don't know how you're planning to use your car, but unless you're putting drag slicks on it, you won't hook up with a heavy dose of the the power from the stock Coyote. And as I recall you did already buy your tires and they're not drag slicks. So you're wasting your time and adding complexity IMO. Not to mention the cost. Build the car, drive it, and do bolt-ons if you still think it matters. That's my advice.

thanks Paul, as always - no nonsense, and appreciated :cool:
