Dyno Jet/Mustang Dyno

[jimberg]

When I took my car to get dynoed, I did 4 or 5 runs. The spread in HP between the different runs was about 20. I don't really see a way that an engine can consistently put down the same amount of HP every time you run it. As Jeff stated, there are a lot of variables.

If you want to compare a bunch of cars ability to spin a drum of a known weight, both the DynoJet and the Mustang dyno should do the trick. Unless the weight of the drums were exactly the same between the DynoJet and the Mustang, I wouldn't try to compare the numbers between the two because the load on the engines would be different and would yield different results. If you want to tune your car against realer world conditions, I'd use a Mustang dyno since it can simulate how your vehicle would truly respond. The load on a DynoJet may not be enough to cause your vehicle to ping, where the load on a Mustang Dyno might, for example.

That's my 2 cents. Hey, Unit, when did you start participating again?
