Icould not ask the complete question above in the title, so I will finish asking my question below.

Would it be possible to get 600 whp and 600 wtq out of a 03 cobra with a ported eaton and mods, not including meth or n20, if so what mods would be necessary to get to my goal if not close to it? If their are any threadswith dyno graphs or information concerning my question above could you please postthe threads thank you? I did some searching but I could not findmuch.

I'm going to say no, not without spray or meth.

no... basically you should leave the eaton alone and add n20... but thats up to you, porting has a nice gain, but i think is hard to get more than 500-530 or so rwhp doing that.. with a half way sane tune

i think it would be possible, but very expensive. i think you would be very close with a stage 5 port, upper and lower pulleys, the right cooling mods, upgraded injectors, BAP, intake full lenght exhaust. ported/ aftermrket heads with an agressive cam set up. you might need to bore and stroke your block as well.

you can get close to 600 tq with ported eaton and 20 psi boost. but you will burn your motor up soon,i had 491/576 with my old eaton set up still wasn't happy so i got the 2.6 k/b. my tq is a little low on the 93 tune, i haven't yet have it checked on a dyno jet yet.
if your goal is to get 600/600 a k/b or whipple isa must. i wasted so much money in the eaton way ,and not to be happy. i should have done it right the 1st time ,jmo.
