Default Are these reasonable gains?

My 95, with just a corsa exhaust and open lid makes 270hp and 320ftlbs at the rear wheels. It is a 6-speed

From what i can determine, this is possibly a bit above average.

Now, add in headers (+18rwhp, +18rwtq), new 8.5MM wires and new plugs (+5rwhp, +5rwtq), for a gain of +23rwph and tq.

That would be then 293rwhp and 343rw tq. Is this reasonable?
That would give me approx 341hp and 403 ft-lbs at the crank. Crazy am I, or do i just have a very strong motor?? :crazy:

Check my mods (below) and I'm making a solid 300 rwhp. You may have to add a 52 Throttle Body and headers to get you where you want to go.

Good luck! :thumbs:

those numbers fact or predicted figures??? I would guess maybe 12 -15 hp for headers and about 10 tq, maybe 1 with plugs and wires. im jus guessing... but 400tq at the crank does sound a lil high.

Wires will not add a single HP. New plugs can restore lost HP, but not really add HP either.

I think 270 rwhp is about normal. My 95 6 speed base dyno'd 271.
