What you think of these dyno #'s
Went to Balancing Act in St.Catharines on Sat. to use their new Mustang Dyno with a couple of friend's Mustangs.
I made 313hp at 6250rpm and 291tq at 4750 with stock PCM and mods in sig.The torque curve was awsome never going below 272 from 2500 to 6250rpm.
AFR was very rich. Ion (madz28.com) is doing a tune just wanted to give him AFR #'s and see what a tune will give me HP wise.
The number's seemed low but my friend ran a 03 SVT Cobra and made 363hp and 414tq with just a blower pully (15psi ) and chip. Other friend with 01 GT made 192hp and 242 tq with intake full exhaust and programed chip.
The dyno was the eddie current road simmulation one.
I think the numbers are a little low but with no tune and compared to the other guys and dosen't seem bad.
What you think!!

Yeah, it's hard to say, since it was a Mustang Dyno.
On a dynojet, I would expect you to run at least 325rwhp/325rwtq, with a tune.
Running rich is really hurting you.

Any guestimate on what dynojet numbers would be??
My friend ran a 97 ws6 at Agostinos and made 278hp and 305tq
with intake , cat-back and hypertech and couldn't get over 100mph at the track.
I think it has to be between 380-350 hp

My mechanic has a Mustng Dyno, and I also has a friend that has a dyno-jet. After we've made comparison on 3 different cars, they all came out at about 5.5% higher on the dynojet.
So, I think his numbers on a dyno-jet would've been 330rwhp, give or take a couple. If you compute the 20% on his 313rwhp, it would've come up to 375rwhp. I think the 5.5% is more realistic.
Of course, all of this with everything being equal. There's always going to be variables that you have to take into account.

lol. I 01 GT with full and intake only 192 hp? I hope that is a typo.
Anyways, that doesn't sound to far off. On a dyno-jet, like others said, close to 330 rwhp. Thats what a lot of hot cam people are putting down. Although you can up more hp once you get a new tune, if it running rich. I would say with a good tune you could put down 335-340 hp.

"Not quite that high. I have personally estimated the difference to be at around 5.5%"
There could be a difference of 5-6% between a Mustang and Dynojet on an inertia type. (no rolling resistance applied to the rollers).
"My friend ran a 97 ws6 at Agostinos and made 278hp and 305tq
with intake , cat-back and hypertech and couldn't get over 100mph at the track."
I don't think I would only gain 35 hp with my mods. from a stock bolt on car.

Stock I could trap 102mph (3.42's) and with the mods now I trapped a best 112.5mph (4.10's).
I think that would take close to 100hp too do.

Mine dynoed 338rwhp on a dynojet with bolt-ons head and cam, and Mac shorties, a couple of years ago, before I went stroker.

I think I will have to go to a Dynojet dyno and compare the two with corrected numbers after i have the tune done and run again on the Mustang dyno.
The guy that owns the shop has a warmed over 396 in a 70 Chevelle that only made 6hp and 65ft-lbs of more than me.
He was pretty impressed with my #'s and said the motor had to be making over 400hp.
BTW the shop also has a flow bench. (Wish I had known before I put the heads on the car)
