my dad owned mustang gt's and i rode in a 99 mustang gt stock not long ago and from what i feel is the power of that underrated 260 hp is faster than some people think, it pinned me to the seat from 1-3 gear's, and also i rode in a 1999 svt cobra conv with 2 girl's and they really didnt get down on it and i know what they are capable of lol, and for the new 03 svt cobra i know a person that own's one and i never rode in it but i know they are some serious torque haulers, well i love american muscle

well i dyno'd 215 ( before i get flamed it was on a MUSTANG dyno ) & they told me that where they had they dyno set, you had to add 33% & that would give you your flywheel hp. with that said i should have around 285.95 hp. & the dyno was done with 735 mi on the car, completely bone stock, so it might have opened up a little since then

I'd be willing to be that SAE you would have showed much better than 215. But I'm sorry, but I don't think there's any way that you had 285 at the crank. What's this crap about adding 33%? Typical drivetrain loss is 15% I dunno, maybe I'm just stupid. Somebody please shoot me.

well mustang dyno's read lower because they actually measure a cars hp based on the car weight & other factors. now other dyno's read higher because they use a base inertia, not specified to each car. which inturn, makes it "look" like you have more of a drivetrain loss

EDIT: the guy that installed the dyno from mustang dyno's told the owner to give that figure to me

I have done some research, because I used a Mustang Dyno as well - they figured the weight of the car at about 3500, I believe. From what I've seen if the weight is accurate in the MD the difference is around 15%-17% between a dynojet and MD. I'll try to find the page with the same car on both dynos and post it up. I think the dynojet uses a fixed weight of 2,000 lbs.

Using 15% (215/.85) it would put you around 259 RWHP. What mods did you have at the time of the dyno?

EDIT: ** My mistake - the Mustang Dyno actually continues to apply resistance, while the Dynojet uses a fixed drum weight - apparently, once you overcome the initial resistance there is no more applied.**

Here is one link: CLICK

Here's another: An '01 Saleen 281 on an MD: 199 RWHP!!! I'd be pissed. lol CLICK

no im not weak and yes it pinned me to the seat, i heard it was stock but could've be wrong and torque hauler means lots of torque its carryin, maybe its not that much underrated but from what i know they are
