this guy with a 05 5 speed said this:
I went to the Dyno stock and ran 263.67 RWHP 284.31 RWTQ. She was running off the chart rich though. Installed a Steeda CAI, w/ Diablo Predator Tune...played around for a bit....282.67 RWHP 302.40 RWTQ and the A/F is much much better about 12.1
sn95 5 speed is like 3250
05+ 5 speed 3450
200 pounds is a pretty good differance....enought to make up for 30-40 hp I would say.
Im sorry to say it, but 200 pounds is NOT enough to make up for 30-40 horsepower, maybe 10 if youre lucky. If that were the case, you could take out your upholstry and spare tire, run on an empty tank, and run 11s !!!! Also, I have done the pi swap, with ALL the bolt ons, headers, coil packs, wires, tune, gears, intake tb, plenum, pullies........... and these cars are just not as fast as the 3v cars. If you are lucky, the guy you are racing sucks, you'll win. My buddy has an 06 with some bolt-ons, and he walks guys with built 302's that lay down 20 more hp at the wheels. He only makes about 290, but the newer engines are just efficient and fast
