Does anybody know the hp at the crank for the '03/'04 cobra w/o its supercharger?

Miliock

same as 01 cobra? guess

I was j/w because I was looking at one and want to put a diff s/c on it. So, knowing the actual hp w/o the s/c would help me determine my new s/c.

Probably whatever the Mach puts out.

doubtful the Mach 1 and the Cobra have the same compression ratio...

a high output NA motor v/s a S/C'd motor ???

99 Cobra Had A higher compression. I think it was 9.5:1 and the Terminators had like 8.5:1

it should be around 305-320 hp. but as others have said compression will change this.

LvGordo

so the s/c only added 20-25% more power? I guess they were underrated at 390crank.

alfromcal846

many people have said they are underrated due to insurance reasons. I mean why is it 390 and not 400. Thats a big difference to insurance agencies although u may think not. I just used 305-320 becuase the mach 1 was at 305 and the 9901 cobras are at 320. so its safe to say it should be around that. But also the 03 04 cobras have forged internals.

this is not really a valid question. you can take the belt off, but the motor will not get enough air, if any at all through the non-spinning s/c. the number you would get from a 03/04 cobra without the belt is not useable as a comparison to anything. it's like asking how much HP a motor would make on half the cylinders.
