So I'm looking to buy a 2012 mustang gt after I build my cobra, because I'd like to use it as a daily driver due to the better gas milage, and better daily drivability compared to the 700 rwhp cobra im planning So what mods am I missing, and how much power do you think I can make without boost? I am unfamiliar with the coyote 5.0 motor. Not really sure what n/a mods are out there... NO NOS
Currently I'm thinking I'll get:
-BAMA custom tune (of course)
-Boss 302 intake with CAI
-Long tube headers
-o/r x pipe
-high flow catback
-bigger throttle body
-Boss 302 cnc machined heads?
-higher lift cams & valve springs?
Any changes or additions? THANKS!

it really sounds good. i heard the max rwhp 5.0 could get is around 465rwhp without poweradder(like turbo or supercharger)

You might want to do some research first. It seems that these engines are breaking with mods as simple as a tune. There's a recent Ford TSB out there about this. The stock 5.0 may be maxed out about as far as it will go without some serious internal mods to help with the extra power (such as what Ford did to the Boss).

Ditch the throttle body..There have been no shown gains (maybe +2) with a larger throttle body until you go forced induction. The build you are showing should put you somewhere in the 550 at the crank 660 to 460 to 470 on the dyno. Just remember(sure you know since your building a cobra) with the boss and the cams you are really changing your car to a higher powerband. Though a full exhaust and headers will help balance the bottom. As for as the car breaking there have been VERY FEW CASES of cylinder 8 failure in this car! Can't imagine buying a mustang and being afraid to mod it screw that. Bama from what I understand are the only guys giving a warranty against #8 failure. And to my knowledge steeda tunes have never had one go bad..good look looks like a great build!
