Default Dyno numbers sound right?

Hows it going guys. A while back my girlfriend bought a modded 00' GT for $5k. The mods that we can tell that came with it is a MAC intake, Trick Flow plenum, Pullies(brand not yet known), BBK long tubes, BBK h-pipe, Ravin mufflers, 3.73 gears, short throw, lowered. And well we finally took my girlfriend's car to get dynoed. The numbers were 239hp and 280trq. I dont know if thats good for this car with the mods that it has or what. I dont even know what these cars put down stock. We were at an elevation of 7,000 + ft. I dont know if that has to do with the numbers either? Let me know what you guys think. All I can say is it sounded GOOD up there on the dyno!

Seems a little low to me. What kind of dyno was it? With those mods I would expect around 250 rwhp or so and a lil' more torque as well. Maybe it was the altitude though.

It does seem kinda low so its probably the altitude.

And of course it sounded good compared to your fire chicken

hmm, does seem kinda low. I made comparable numbers with just an no name x-pipe and flowmater mufflers. I out down 230hp on a dyno jet before I did any serious mods. I don't recall how much torque at the time. How many miles does the car have? It could probably use a tune up and a tune.

Do the altitude math and convert the #s for us. Then you won't get so many "dunno" responses.

Sounds low but up here at that altitude they automatically correct it for you to sea level. Where do you live? I live at 8500 ft. . .

well saeis already corrected for altitude on the dyno jet, soo it is way lower than it should be, i would think. SAE" horsepower is corrected for temp, humidity, and elevation.
