S550 Upside Down and on the Wrong Side Build Thread Profile - S550 Mustangs

I think you are pretty much bang on the typical numbers assuming you do not have headers and Lm intake only cams etc. Headers/LM cam would help the midrange as well. My local shop and AED in the US, say that 500Hp is very normal with Headers, CAI and E85. Since mine is a gen1/2/3 Hybrid, it took all the goodies to get it over 500 rhwp. Don't forget that the Cobrajet manifolds needs porting!! Not a production piece...

My current problem is i have headers, ported Cobra Jet and the L&M intake cams. Fuel is our 98 which is US 93 i think, its our premium.
I expected to loose some to my stock manifold down low but not as much. It should be on the dyno at the moment to have another go at fattening the lower end. Unfortunately they don't have the experience the guys in the US have on this kind of setup. Unfortunately no one in the US wanted to touch a non US spec ecu.

Consider the fact that you really need the Gen 3 bottom end (12:1 compression) and E85 fuel to get to that 500 WHP numbers most of the Gen 3 cars make with all the goodies. In your case I think 440 WHP should be somewhere around the maximum. That lack of tuning options for the non US spec cars was the reason I went with Power Pack 3 setup.
