sorry this is my first post here, i always look at the board but have never posted anything,
i have an appointment today to dyno on a dynojet
anybody care to take guesses at my numbers, i should be back to post up numbers in a couple hours

99 SS 64000 miles
6 Speed, whisper lid, K&N filter,
not sure on the exact exhuast setup, since i bought it like this
but it looks to me like MAC midlength headers, y-pipe with no cats, and a corsa cat back

this car could have more done to it, and i just simply dont know about it yet, one of the reasons i am dynoing,

so what does everybody think i will put down?

There's no way to even guess since you don't know what mods it has. You could have a baby cam in it for all we know.

I'm going to assume that it only has full exhaust and a lid. My guess is 330rwhp.

does it have an upgraded intake

From what you have told us I would guess anywhere from 330 to 340.

333.5 is my guess.

Given the time of the year, heat, humidity... I'll guess 320.

I'll guess 335 RWHP SAE-Fred

Sounds about right for a 99. You should look into getting the LS6 intake.

I would have thought 320, but it is only a little off for a 99. It may need a tune.
