That's my guess. I will be dynoing on our Mustang Dyno, probably Tuesday and Wednesday.

A friend with the same mods and an M6 made a little over 390/380 on a SuperFlo....but I know my stall will eat some HP.



What's your guess? Opinions?

my parts list & dyno unlocked. Was expecting less tq more hp but it worked out well, just needed to move to ET's as nitto's didn't work out any more.

My guess on a Mustang Dyno 350/350 range.

Well it did 316hp/302tq, converter unlocked. I honestly though it would do 320.

I think these are pretty accurate numbers. I also did the 1/4 mile run on the dyno....12.33 @ 112 vs a real world time of 12.22 @ 111.



BTW, a friend of mine has a G-Tech so we did the HP test from a 2nd gear roll. It showed 320. I guess those things are more accurate than I thought.

WIth a TR 224 cam I would have expected alot more. Do you have it tuned yet?? Mine dyno's 320's hp and 370's tq in a stock internal car w/ a 3800 stall

No tune. Did you dyno on a Mustang?


Mine did 280 all stock on this same dyno.

ive got the same mods, except a vig3600, and pulled 338hp and 343tq on a dynojet. i was kinda disappointed. But i'd say yours is about right since it was on a mustang dyno.

post up your stock/post-mod overlay dyno sheet, that tells the best story mate.

they did force unlock the tranny in 3rd gear and run it?

dyno's are great for baselines and after mod changes but you just can't compare them esp different brands even on the same day.

I dyno'd it myself and yes, the tranny was unlocked during the runs.

Bone stock it did 280/290...now it did 316/302. The torque curve is flat from 4100 (where I started the pull) to 5300...

This is a very strange thread. One dude's got 481rwtq from a TR224, and another only has 316rwhp?? both those numbers are way off the map of where they should be.

Even on a mustang dyno, with an auto and your converter, you should be in the 340-350rwhp range. Most M6's are in the 370-390rwhp range (dynojet) with a TR224 + all the other bolton's which is appears you have for the most part.

As far as that 481rwtq, something messed up with that dyno, lol.

I'm not too concerned about where it dynos really. Yesterday we had a stock 99 M6 SS on the dyno and it put down 292hp (and the tq was messed up so I dont know what that was). All he had was a lid.

Some will say with all my mods I only dyno'd 24 hp more and that's pathetic. Well, maybe. But I ran a 12.33 @ 112 with a 1.86 60' with Nittos on our dyno compared to my time in the sig. My best 60' in real life is 1.70. He let me run his car and the best was a 13.56 @ 105 with a 2.03 60' on street tires. I think that's about the best that car would do at the track too....I can't see a better 60' than that on street tires especially with an M6 and my mediocre manual tranny skills.

We used the same hp @ 50 (12.4) and weight (3750) for both cars. This information came from a spreadsheet that was supplied with the mustang software I believe. However, the EPA website lists these cars as 8.6 hp @ 50 and 3820 lbs or something like that. ???

Anyhow, I'm happy with how the car runs...low dyno numbers or not.

your friend has 390/380 on a dynojet and with the same mods you have 316/302?? Thats crazy. I would say that the mustang dyno reads really low, but if your other friend hit 292 on a bone stock 99 M6 than it's safe to say if anything it reads high for a mustang dyno. The difference in your track time's is significant. so you obviously have a lot better power under the curve and it almost seems like the dyno is not reading your peak numbers correctly or something is hindering your peak#'s. What does your other friend w/390/380 run at the track?

Considering you slapped a bigger power robbing stall
in your ride and since it is not tuned - 36 HP doesnt
sound horrible. I bet once it is tuned it will pick up
some missing power. Now if an individual is worried about their
gains and since you dynoed before unlocked - a person
could put the stock converter back in and redyno with the
rest of the mods still in place, but that seems drastic. Also just
compare before and after graphs you may have picked up bunches
other than at peak?? Otherwise I think your car is doing just fine.

In comparision
When my A4 was making 345 HP on a Dynojet
It went 12.4x @ 110 - with 221 cam (headers/3500stall...)
U are @ 12.2x @ 111 - with 224 cam (headers/3500stall...)

My car stock did 280, which seems like a reasonable loss going from an M6 to A4 numbers.

The launch with the M6 is the limiting factor...off No2 I have witnessed 12.5s...on No2 I have seen 12.1s. This is on 275 Nittos, full weight, and a lowered car. His numbers came from a SuperFlow dyno.

Yeah, I knew the stall would eat some HP. From evey car I have raced and knowing what they have dynoed, I would have guessed my car would have done 340-350 on a DynoJet.

But either way, a gain is a gain and that's what a dyno is for...a comparison tool. Its nice to see how accurate the dyno reports the 1/4 mile times since I have real timeslips to compare it to. I think the Mustang Dyno is a nice piece of equipment. A lot of people dont want to dyno on them because they know they will read the lowest of all popular dynos...

Also, 316 HP at the wheels, when 25% drivetrain loss is factored in comes out to 421 HP at the engine. I think this is a very accurate number. 25% loss for an auto is not out of the question, especially one with a higher stall.

I agree..... I am at 343/320 with headers/stall and went 12.53 @ 109.xx.
I wish I was that close to the 11's.
