how much horsepower do u think i have at the crank and at the wheels. i have a 97 ss with mid tube headers, loudmouth resonator, hypertech power tune, 160 thermostat, msd opti, wires, coil, 58mm throttlebody with coolant bypassed, 1:6 roller rockers, the 90mm granatelli MAF, k&n filter, no cats, electric water pump, 3:73 gears

 

This is SWAG (Scientific Wild *** Guess)
Add them up:
Headers- 15 HP
Hypertech 5-10 HP. You should get the PCM tuned to account for all your mods
160 stat- 2 HP If fans are set up accordingly, otherwise very little
MSD opti- 0 HP no gain over a good opti
1.6 rollers- 15 HP
58mm Th Body 2 HP really does nothing till over 400HP
90mm MAF - 0 HP ditto
K&N filter - 0 HP no gain over a clean filter
No cats - 3-4 HP car had High flow cats already
electric pump - 5 HP at high RPM (0 at low rpm)
3.73 gears 0 HP Gears do not change HP

 

probly around 310RWHP, but it could be less or more, get a good tune and go to the Dyno.
