Mine makes 312 with intake, midpipe, catback and tune. With longtubes probably about 320 or something. Stock maybe 280.

My '99 is making 262 RWHP with cams that aren't degreed/matched and no tune.

It's luck of the draw.....that (degree matching cams) supposedly will net you 20 HP....this makes sense because mine is likely making 300 at the flywheel..

cams degree matched (if needed), LT or ML hreaders, complete March UD pulley set and a BAMA tune should get you in the 300 RWHP range.


comp cams...maybe 340+ ...about 50+ guessing...depends on the cams.


ported intake, 90mm MAF, 39-42# injectors, and fuel pump...???

NASVT is the expert on the NA 4V mods...search his posts...on all the forums....especially stuff about cam selection...

On a dynojet my '99 made 291rwhp with a JLT CAI, SLP catted-X, and Magnaflow exhaust. I never had it dyno'd stock, but the 99/01 Cobra should be in the low to mid 270's. I'm hoping that by adding Mac longtubes, Mac catted-H, intake spacer, and a generic tune that I'll be somewhere around 310ish. Custom tune somewhere in the 320-330 range.

With Mac Long tubes off road h pipe , Mac Catback , JLT Intake and a SCT canned tune mine put down 315 rwhp on a MD. Also was running 12.4s @110 mph in the 1/4 if that helps any.

My 99 with MAC longtubes, O/X, magnapack CB, JLT CIA, with a SRA swap ( eats up about 10 rwhp over IRS) put down 318 rwhp, 310 rwtq with 135,000 miles on the clock. I would say your looking at 300-320ish rwhp depending on can or dyno tune.

SRA stands for solid rear axle...and I thought I had always heard that the IRS would put down less power, not the other way around?

wow, your thriwing down a good track time with that set up... I have ca I throttle body upr x with catback, I was running 14.3 best but it was my first trip to the track, and first stick I have ever raced. did the gears really wake up the car?? I was thinking about 3;73 as opposed to other options.. anyone know what kinda quarter mile time improvements you can see with the diff gears?

They help but it's harder to launch unless you have a tire. For reference I went 13.3 @ 105 bone stock back in 02 and with the 4.30 and cai I did a 13.3 106. But to be fair the 2nd was into a 20 mph headwind.
