How many RWHP do you think these bolt-ons would make on a 2012 Mustang GT 6MT on a Dynojet?
- FRPP BOSS intake manifold
- 84.5mm throttle body
- C&L cold air intake
- Accel Super Coils
- 3" cat-back exhaust with x-pipe
- 93 octane tune

Other than nitrous or forced induction, what other engine mods would you add to this list?

With who's tunes or will you be getting a dyno tune?

Scrap the coils. Not only are the gains only minimal on an SC'd engine, they can be problematic. Also, the cat back won't gain much and the x-pipe does very little; maybe a few single-digit RWHP if any. And the TB may also be iffy for gains unless it works well with the BOSS manifold.

All-in-all, assuming a good tune, I'd say about 410-415 RWHP.

Thanks, Nuke!

Assuming 370 RWHP stock, that's like about 40-45 more, which sounds pretty good to me. I want to stay NA, and drive it an hour and a half in traffic to and from work every day, so I'm not building a racer.

I've heard mixed reviews on the coils...just thought I'd throw that in to see what folks on the forum thought. Would probably be better off spending that money on shorter gears for the rear end.

Would that be an off road x pipe?

the exhaust does add some, more than single digits but also not the high amounts advertised. more like 15. You will see a gain in high end hp on the boss intake and throttle body, but a loss in tq. However if untuned now, the tune will negate any losses so you will not feel it. However if you want torque stay away from the boss intake. I have it on mine, but I also rev my car to 7800 rpms. And they are right, the coils will do nothing, the stock units are more than enough and will actually last. when its all said and done on a good tune you should be at 415-420 on a dynojet.

I had cold air, axle backs and tune and made some gain. I just installed Boss Intake and BBK 85 throttle body and oh my. Insane gain low mid and high.
