Mustang dyno vs. Dynojet
 

Ok, I had my first dyno done yesterday. I'll admit, I'm not very knowledgable about these dyno machines and such. So I have to ask, what is the difference between a Mustang dynamometer (which is what my car was done on) and a Dynojet? I know the mustang dyno's readout less than the dynojet, but what are each of these test machines measuring? And typically how much above a mustang dyno readout will a dynojet readout be?

And just to ask yet one more question....what do most of you guys quote for your hp ratings: mustang dyno numbers or dynojet?

there is an article in the new modified mustang magazine about this but i havent read that far into it yet, just read the first articles so far, c if u can find that mag

RE: Mustang dyno vs. Dynojet
 

i think the mustang dyno reads around 10% less because it takes vehicle weight and some other factors into consideration.
I go by the dynoject numbers because around here that seems to be what everybody uses.

RE: Mustang dyno vs. Dynojet
 

They take into account weight? I know that affects 1/4 mile time, but that has nothing to do with horsepower. That is stupid. Maybe I am wrong, I dunno.

Lets say a honda with dynos 250 HP and weighs 2000 lbs.
now a mustang dynos and makes 300 on a regular dyno.
it would dyno on a mustang dyno at 270 because it takes into consideration the weight of the car so you can see what your cars compare as.

can anybody help, is this true?

RE: Mustang dyno vs. Dynojet
 

Yeah, but that would only work if everyone used that kind of dyno. If I show a friend my dyno sheet and it says 300hp and I tell him I really have 400, but the dyno does some math and lowers your horsepower, they would all just laugh and tell me I was a liar.

RE: Mustang dyno vs. Dynojet
 

Weight really has no affect on how much HP a car puts down. The reason the two dynos will show different numbers is because of how they are loaded. Check out the web sites for a better explination, I am too lazy to type it all out, but basicly Mustang Dynos are better for tuning a car as they simulate the real world better, if all you care about is braging about numbers go to a Dynojet.

Thanks JD.........so I'm to assume that many of the ppl on this forum quote dynojet numbers for their power output estimates?[8D]

RE: Mustang dyno vs. Dynojet
 

LOL I am not sure about that one:D Actually I think that the Mustang dyno is becoming more and more wide spread.
