How much power from these mods

[96z28]

How much power would I get from Hooker long tubes, off road y-pipe, slp loudmouths, slp cold air intake, and polished intake elbow. Right now im bone stock other than flowmasters and they will be no more with this set up.

I've got the same, minus the headers and y-pipe. I would say you're good for about 20-30 just with the CAI and exhaust, so plus the headers and off-road y would probably get you about 35-50 easy. I'm sure Fred could probably give you a better estimate though. Another thing you might want to consider is the SLP throttle body air-foil...it'll add a little extra and its cheap. The 1LE driveshaft would also be good. Also, don't forget to beef up the suspension while you're at it. LCAs and a panhard rod are a good start, sway bars and a torque arm would be the way to top it off. A shift kit for the tranny will also help you get better and quicker shifts.

is that rear wheel or crank horsepower

Crank. Subtract about 20-25% and that will give you wheel. I'm not quite sure, but the shift kit MAY bring that down slightly. One other good thing to invest in...a good set of sub-frame connectors. You car will ride smoother, turn better and hook up much better. Can't forget about the suspension and chassis
