Mustang dyno ? dyno sheet inside
Mustang dyno ? dyno sheet inside what is the standard conversion from Mustang to DynoJet numbers ? I dynoed on a DynoJet in April and got 376 rwhp, I dyno'd today on a Mustang and got 362 rwhp. I know I didnt lose 14 rwhp and my trap speed at the track is between 111.9 - 112.7. The guy at the dyno said there would be a little difference but not much, I told him my dyno numbers didnt jive with my trap speed at the track or my butt, cause I know my car runs way better now than it did in April. thanx

You may get all kinds of estimated # for a conversion but there is NO such thng. Best thing is to stick to the same dyno or get a baseline test before any changes are made.
Don't sweat it, it is just a number!

like I said before track times say 389-394 rwhp....there's absolutley no way my car lost 14 rwhp since April...there has to be some kind of calculation for the offset, I know it's just a number, but the Dynojet is almost an hour away, while the Mustang is 5 minutes away,but the owner of the Mustang is kind of a douche bag...I wanted to get good before and after numbers from the head swap, but the current numbers have me a little down, if they're correct
you know you put down on the mustang dyno so use that one as ur baseline for before and after heads, also from what i hear mustang dynos are more accurate, what times are you running at the track and what mods do you have

In my personal experience, the Dynojet was about 13% higher than the Mustang Dyno. I dynoed on the Mustang dyno and then a week or so later on the Dynojet and they were just about 13% different. But, I think the difference is different for each car. I know that the Mustang dyno is more accurate because it accounts for load, etc. I just got Dynojet numbers because it's easier to spit them off to some people without having to explain why the numbers are so "low".
i think the Mustang Dyno is more dependant with the operator than a Dyno Jet would be, I noticed the load setting was set at 4% grade.....Mustang is better for tuning than a Dyno Jet, because of the loading factor
