Does anyone know the horsepower difference between these two?

We dynoed a 360 rwhp car on a Mustang dyno and I was curious what would its equivalent be on a DynoJet?

Thanks.

 

one of my buddies dynoed 356 rw on a mustang dyno and said it was like 376ish on a dynojet, so i'd like to know also b/c my tuner does tuning on a mustang dyno

 

the mustang dyno puts loads on the car like normal driving around the town would, and the dynojet just has the car spin the rollers.

at least thats what i think! the mustang typically reads 20-30 hp less than dynojet, and the dynojet is the industry standard

 

That makes me feel happy. I dyno around 270 on a Mustang dyno so I guess that puts me around 290 or 300. Not bad. I have a few germlins I need to take care of and should be higher than that and I installed the AFPR. The Mustang dyno is supposed to be better for tuning as it simulates real world driving better than the Dynojet.

 

Here's a link that explains the differences pretty well:

From what I've read, the conversion factor from mustang to dynojet is roughly 12% which seems pretty accurate from the dynojet mustang comparisons I've seen with similar mods.

 

Cool.

I got 268 HP which means if the margin of error is actually 12% I'm at 300 HP baby! My AFPR should knock me up to around 310 hopefully. I've run neck and neck with many a LS1 and actually edge them out slightly.

 

I was with an f-body group that dynoed on a DynoJet 248c and two months later they went to a Mustang dyno. I wasn't there but they all consistently had higher numbers of about 20rwhp on the Mustang!

 

Here's an article from one of the mags including dynographs etc....
