Default cam and nitrous numbers for 04 GTO

just had my car tuned by speed inc right after i got my tr224 cam in the goat and it is a world of difference. all motor i dynoed 392.55rwhp and 372.82 torque and on the bottle i dynoed 451.20rwhp and 460.56 torque. i was told the nitrous numbers were low because of bottle pressure but the n/a numbers were very good! what do you guys think?? here is the graph mods are in sig

dont forget that zex kits are flywheel rated(100 shot is prolly 80rw), and lower bottle pressure deffinitly affects power. get a nx bottle heater to keep it at 1050psi

it was about 800-850 psi, certainly not high enough

Nice numbers.

800-850 is def. a little low. If you have the Zex heater, I suggest getting different heater. It will only keep the bottle pressure around 800-950.

I am getting dynoed on Wed. and I will post up the results. I have the same cam as you but I am an auto. Same headers too. Just no ported TB or pulley.

cool man, i was thinking of getting a different bottle heater. you will love the cam by the way, very nice powerband. if you can i would suggest getting a pully as it does free up some hp, otherwise good luck with the tune and numbers. but ive always heard not to get too caught up in the #s
