since i don't have a scanner, this is the best i can do ;)
in case you can't see it clear, it is 146.1 HP @6400rpm and 140.4 TQ @4400rpm at the wheel. cam gear settings are at -5 INTAKE, and +4 EXHAUST
I forgot to get the baseline print out when the gears were at 0, 0, but it was 139HP peak and 135TQ peak, and now i'm gaining both HP and TQ in all RPM.
I could make it to get 2 more HP at the peak but i would lose a lot TQ and a little HP from idle to 5700RPM that's why i left it like this...
the dyno guy told me that i should be able to get 150HP or higher if i don't have a cat (or a high-flow cat), since now i only have a regular universial cat which is quite restrictive.
ok heres my question, i have crower stage II and early 2000 intake manifold as 2 of my mods, and i saw other ppl are getting power all the way to 7000RPM. i'm just wondering why my power curve starts to go down after 6400RPM? Will this be due to the regular universial cat?? that is restricting my air flow especially at high RPM when it actually needs more flow???
thanks a lot, please help.
