Went to a dynoday yesterday and got a couple pulls done. The printer was down so they couldn't give me my graphs and A/F ratios at the time. I took a couple screen shots and saved them to a USB drive, a graph and peak number window for now. These were done on a Mustang dyno in 5th, temperature outside was around 15 deg C or about 60 deg F. I was told these were SAE corrected nums.


OH...The car wasn't taken to redline cause the operator mistook the shift light in the tach as the redline warning light or something. The graph hasn't taperred off by ~6000 RPM so there must have been some more power left. I hit 255.6 and 253.8 Whp. I had him go up to 6500 on the last pull, the wideband sensor wire got F'd up along the pull and he hesitated as the screen showed I was at 22 A/F, thats why the last graph looks like ****, and shows less power I'm guessing.

I'll be going back sometime to get my A/F graphs and a decent printout.

Tell me what you guys think. I was told these numbers weren't inflated to reflect Dynojet numbers but they are SAE corrected. Does that make sense?

 

Those seem like good numbers considering the situations. What were you expecting to get, higher, lower?

 

Looks like that Mustang dyno wasnt a load base dyno or they had it set up to read like DynoJet numbers . A load based Mustang dyno...set up right . Numbers will come out around 190 to 220whp on a 03 Z or G

 

Good numbers


I dynoed on a mustang dyno with same mods plus crank pully and dynoed 249whp. Some Z's that day where dynoing in the 220 range with intake and exhaust. I dont see how it isn't possible, I dynoed in 90 degree heat. His dyno was in 60 somthig degrees so I dont see anything wrong with the numbers he put out.

 

I believe Mustang makes both load based and DynoJet [TYPE ] dyno's . The load based dyno [ what little I know about it ] can be set up for different ramp up speeds , Wt. can be raised or lowered of the car . Quite a few things can be altered to change the results given .

 

I dynoed before on a different dyno, a dynojet with from what I can remember a stock setup and it put down 246 WHp in 85 deg weather. So I was expecting lower numbers this time around knowing it is a Mustang dyno and from what I've seen on the boards they dyno over 10% lower than the dynojet. I do have a fair amount of breathing mods so who knows, but I seriously doubt I got 25-35 Whp from my mods.

I guess this was pretty inconclusive.

I dynoed higher than a friend's rebuilt 69 comaro so it wasn't a complete loss of $50.

 

To add, they were performing 1/4 mile runs on the dyno so it must be load based, unless they can change it on a whim.
