Mustang vs. Dynojet
Re: Mustang vs. Dynojet I read an article lately, and IIRC, the gist of it was that the Mustang dyno has a provisionable parameter to take into account rolling/aerodynamic drag. That is to say that the Mustang drags the brakes on the rollers according to what the variable is set to. I think. 
Anyhoo, the article had a car dyno'd on a DynoJet, a Mustang, and they had an optical 5th wheel as well... they found that actual 50-70 times (as measured by the 5th wheel) were MUCH closer on the Mustang dyno than on the DynoJet. Additionally, IIRC, a DynoJet simulates something like a 2450 pound load (the weight of the drum??); so if your car weighed 2450 pounds, your acceleration times while rolling would be approximately the same as on a DynoJet or a Mustang dyno. I think.

Re: Mustang vs. Dynojet Mustang is better for tuning as the load is programable depending on the type of car.
So you could dyno a 4000 lbs truck and then a 2200 lbs car, and get a better tune as the dyno could be optimized for each.

Re: Mustang vs. Dynojet a mustang dyno is an eddy current dyno. a dynojet is an inertia dyno. most eddy currents dyno lower. besides mustangs are always down on power...

Re: Mustang vs. Dynojet i researched it and i found that it was somthing like 11 percent less then a dynojet.
Check my sig. Mustang dyno numbers, yet i am pulling alot of mph in the quarter.
A general rule
e.t. is a function of traction
mph is a function of hp

I wish I had a 12 bolt! 1/4 mile times suck major, major *** (I've only run 2 passes w/ this setup), as I spin the stock Goodyears F1's 'till deep into 3rd gear! That said, my only traction gear is 4th. Even then I trap @ 111. Er, eh, cough cough, 13.0 w/ 2.2
Nittos anyone?Ain't got no traction baby!!!
