95 Max SE 130,000 (hard miles) Stillen pop and Warpspeed Y pipe. 5 speed. Dyno was taken w/ car in 3rd on a Dynojet 248C
71.4 degress 29.36-0.44 in.Hg.
The numbers
Max Horsepower 177.4 at 5180 rpm
Max Torque 186.3 at 4490 rpm
I don't have a way to scan this in yet but my torque curve is fairly flat 2-3 k rpm then spikes to 184 at 3300 then drops at similar rate back to pre 3300 #'s at 3600 then produces a much broader curve that peaks at 4490 and then drops like an anvil after 5300. SO my torque curve is flat,spike,gradual curve.
Horsepower curve is fairly linear w/ a slight increase from 3100 - 3300 rpm then falls back a bit and then climbs again (linearly) 3800 to 5300 where it hangs flat until about 5700 where it starts to slowly drop.
I'd like to see more of these posts. When I get a chance I'll try to edit all me text w/ a graph.

Maybe it's the Cattman Y pipe. Gotta check it.

Good luck. I'd figure it out before I put the S/C on it or you might be disappointed w/ that.

Only buy Texaco 92 or 93, depending on where I get gas
Plugs are brand new NGK Plats (3k on them)
No oil loss whatsover, had it changed a week before the Dyno.
Compression is 10:1...perfect.
Altitude is 200 feet.
My car also feels perfectly fine.
It could still be the Dyno. On another run at another place, I got the same numbers, but then the guy mentioned that the way they were doing it is the "more correct" reading and not the way "most" people do it.
We re-did the Dyno the "usual" way and it came out to 169hp and 185tq.
So maybe it was the Dyno....still worries me, that's all, because I don't know what to believe.
