Taking it for a dyno run tomorrow. Stock specs have the 98 at 225HP and 290 ft lbs. Lets see who can guess the closest numbers it will come in at.
Car has BBK CAI, 75mm BBK throttle body, C&L Plenum, Diablo custom 93 octane perforance tune, Steeda Pulleys, Screamin Demon coil packs with Live Wires, PI Intake (without PI heads), MAC Offroad H pipe, Flowmaster 40 series mufflers, aluminum drive shaft, 3:73 gears?
Also wondering what it would do for me to add MAC Long Tune headers.
Guy's got quite a bit to only be getting 225......come on now
But doesn't have anything that adds much horsepower besides the PI intake and midpipe. Given that NPI cars typically dyno around 190 stock (some don't even get close to that though, I'm being nice there), I think 225 is very reasonable for the mods.

If it weren't for physics and law enforcement, I'd be unstoppable.
