Mach 1/Bullitt intake manifold

[ice445]

I'm curious if anyone knows if these manifolds are plug and play on the 18-23 GT? I know it's basically the gt350 manifold but I'm pretty sure that has different electrical connectors or something else that has to be adapted, so I'm curious if these get around that.

Member Flyhalf might have an answer for you.

If you can give me a VIN for a Bullit or a mach1 I will look at the tune and that will tell me which IMRC system they use.

Thanks, I'm glad it works but I was hoping to avoid all those extra steps.

Maybe he can give one? Or I can look around when I get home. Thank you though.

there are differences in the Mach1/bullitt tune related to the manifold, so i suspect a tune update is required.

@junits15

DO you have a Bullit/Mach 1 tune?

If so look at the slope and voltage for the IMRC. Post them and I can answer OP's question.

or Post the OSID

IMO it may or may not work.
BTW, the GT350 Intake is only marginally better than yours.

Yeah, I know it's not better performing by much or at all, I want to do the swap more for packaging reasons so I don't need the 87mm throttle body adapter anymore. But it's not worth it if I have to do a bunch of extra work to get it to work with the car haha

I do actually i'll send it to you this afternoon.

Looking at a Mach 1 tune it uses the IMRC settings from Gen 3. This leads me to believe it would be a plug and play manifold on 18 up.

That's awesome to hear, thanks for checking into that

It unfortunately is not plug and play. I installed a mach one manifold on my 21 gt that already had the ford performance tune/ throttle body etc. The imrc plugs are different, and when I did the swap there were no adapters available. I had to splice the correct connectors on. The imrc's did not work with the ford tune. I ended up going with a wengerd e85 tune and the imrc function needed to be modified in the tune. It did work flawlessly once tuned. Since have gone ess supercharged and still tuned with wengerd, with functional imrc's

Damn, well thanks for clearing that up. I hadn't seen anyone else try so that's good info.

Are you sure that is a Mach 1/Bullit manifold? It looks to be a GT350 due to the gen 2 IMRC controls on the rear.
