2001 SS M6
Mods: Clear Lid, Smooth Bellow, Magna-Flow cat back exhaust.
The dyno was a dynapack chassis dynamometer:
336.6 hp @5199, 369.9 ft-lbs @4175.
The A/f was 14 @3000 to 13 @5500
I have a feeling there is something off, the torque seems really high.
The shop has been open for a year now and specialize in imports; my Camaro got the third highest dyno numbers they have ever had (First Chevy they have done). Not to bad for a mostly stock Camaro with 92xxx miles. The funniest part to me is that they told me their dyno will read 15-25 hp less than a dynojet, seems like ricer math to me.
Let me know what you think, has anyone else on here run their car on a dynapack?
My theories as to why it dynoed so high:
1)Operator Error, something was wrong with their dyno. Does anyone know how much room there is for programming error with the dynapack?
2)Wrong gearing in dyno, the pull was in 4th, car has stock rearend gears (3.42) but the dyno sheet showed a gear ratio of 3.299. The operator told me that that is the gear ratio with the dynapack gearing taken into account.
3) UNLIKELY: My car has a cam that i dont know about, it started "breaking up" above 4500-4800 rpm, maybe there was a cam installed (i just bought the car 5000 miles ago) and the motor started pinging before it made its max hp. I dont think this is the case though, the car feels stock to me. (I also have a 1980 Camaro that puts out just over 400 at the motor and that one feels faster.)
Let me know what you think.
