5.0 Dyno Chart Compilation

I figured it would be up there... are you getting any slip with the griptec?

None at all. It works great. I wouldn't be able to run a standard pulley this small with the 6 rib setup. This pulley at sea level would be making somewhere around 16 psi give or take. But up here, Im maxing out the blower speed at 7,500 rpm engine speed, just to make 12.8 psi. Probably should have gone with a D1x, but its plenty fast for a street car.

That’s good to know... I’m only at about 1200 ft but my 3.4” pulley is only making about 11lbs. I’m thinking it has to be belt slip.

Yeah I would expect to see around 13 or so with that pulley. I'm using the Gates green belt as well. There's a lot of other variables though that contribute to measured boost pressure. You may have a small boost like somewhere and be losing one or two PSI through the system. Look around especially at the supercharger pulley for belt dust. The other advantage to a pulley like the griptech Is it you don't have to put so much tension on all of the pulleys and the belt to make it hook up.

I guess I'm not that smart, because I am not understanding your Dyno graph.

Yes I figured that I was referring more to the graph itself where what appears to be the torque curve has the higher number on it, and the horsepower curve has the lower number.

Well yes the blue is Kilowatts (horsepower) and red is Newton meters (torque). The graph goes from left (2000rpm) to right (8000rpm).

I give um hell. I don't want them to forget about American Muscle

The left and right scales are different ranges. On dyno graphs, the torque curve is always flatter than the HP curve.

It's printed in portrait and not in landscape like most.

That really doesn't matter ... that's what scales and units are for.
