Performance mods
I know this topic was dicussed a lot of times, but i couldnt find the straight answer. can anyone tell me, is it possible, without supercharging 97 max, to bring it to 250s hoprsepower level. Basically, add 70 horses w/o supercharging it
thanx

To the wheels, no without spending large quantities of cash. anything is possible. It would be far cheaper to SC
To the crank. possibly, but will still cost ya. The parts are available to hit that. Check out Ironlung's post, he's got cams, headers, mevi, and some other stuff and is pushing in the neighborhood of 250 at the crank.

you would need mevi and ecu, new cams, pistons, valves and springs, intake, high flow exhaust...and probably still not get 250wheel horse power, crank...maybe. Nos would get you there, but the power would be in a bottle, not on tap at all times. I seriously think supercharging would be a smarter option. If you can get a turbo, even better

Iron Lung has 215 WHP N/A, and this without the raised rev-limiter. If he could somehow find a way to get the limiter removed on his '99, he would be looking at well over 220 WHP because as is, his HP curve keeps going up to redline...

what do you mean it wouldnt do anything? you smoke the rock, and your sig has been used by several different org members 
You can gain up to 30 horsepower at the peak with a mevi, and lose like 8-16 across the band. doesnt just magically move the power around. read up about the mevi

you are contradicting yourself with what you're saying anyway. Usually about 8-18 hp and torque across the band is what you lose. across the band is everywhere. could be down low, could be mid range. peak is where you gain it back. smarty pants? .....anyway
not the loses ACROSS THE BAND? its especially worse midranger instead of low end

In a way he's right SXN, because users (5-speed anyway) that installed the MEVI without the JWT ECU didn't see gains in the 1/4 mile because the gains up top basically equaled the losses down low. So essenially the power is basically cut and pasted up top...

If you're making that much NA hp you might oughtta consider getting larger injectors.

True. But there are gains, and then there are gains in peak power. The MEVI will give about 30 hp to everybody at redline. For NA people, the power at redline has dropped significantly so that peak gains are small. Supercharged people enjoy a monotonically (if you ignore minor variations) rising power curve all the way to redline, so that extra 30 hp does translate to a 30 hp gain in peak power.
