23psi tune, not overly aggressive. Keep in mind that it is on a mustang dyno, add 12% to get dynojet numbers (rough estimate anyway)

 

thats a good looking powercurve.

 

I definitely agree that power readings are noticably lower on a mustang, however those do seem a click on the low side. Either way, the power curve is definitely healthy looking..

 

forgot to mention, 92-93*F with 60% or so humidity. Muggy ass south fla weather FTL.

 

When I did my dyno pulls on the mustang dyno it was in the upper 80's - lower 90's and raining.. You can't exactly get much more humid than a rain storm.. Just saying..

 

idk man, I have the same mods you have except I have a K&N SRI instead of a hahn, and vince says the tune looks great, he seemed impressed with the gains. I'd say it's probably the south florida weather.

 

Gotta be a heartbreaker dyno.

 

I'm sure it still pulls like a bat out of hell man! Gotta love those heart breakers! Although it will be great when you smoke someone putting down bigger numbers than you, and you can just shrug your shoulders and say.. IDK man, my car only makes 270whp. You must just suck at driving..

 

yeah that too, lol. It's known for being one of the lowest reading dynos around. I'm gonna take it down to ft lauderdale where another member on here made like 350whp and 390wtq with the same mods. LOL

 

good power band! nice

 

The torque band kinda looks like a boobie... I love boobies so by defaut I love the power haha, nice pull

 

Let me know when your going

When we gonna race

 

i'm guessing those are your stock numbers right below it ? if so .. then thats a 56 wtrq and 39 whp gain.. which is impressive..

the fact that your dynoing 10 whp and about 15 wtrq lower then most people do stock shows you're still putting down great numbers man.. dont be upset by the numbers.. look at the actual gains ..

 

Nice numbers. Mustang dyno's read 11-15% lower than a Dyno jet. Some read lower than others, look at my sig. That was on a heartbreaker.

 

Call this bench racing..whatever...
If that's the stock run he seems to be showing (Dashed blue line), then he appears to around 15 HP less than stock (245 vs 230 here). That's about 6% less than a dynojet.
Torque was 220 vs 245 stock or 8% less. Splitting the difference you have around 7% less than one would expect from a dynojet, not 12%. Mustangs are *hearbreakers* for sure..but not *heart attackers*.

Here I found this on a car tested both ways:

Bimmerforums - The Ultimate BMW Forum - View Single Post - Dyno Correction Factors: Mustang vs DynoJet



When I had my car on the dyno in Feb there was a M5 that got 343 at the wheels on a dynojet but on aa Mustang it comes up as 318hp. There is a difference.

YEP..7%

 

So you're saying you're good for 381 HP on a dynojet?...HMMMMM

 

Yeah, anywhere from 375-400whp with matching torque.

 

good number's but idk with me GMS1 I had 306tq 282hp on zzp's mustang dyno weather mids 80s 75%humidity weird

 

Proof is in the trap speed. Now go to the track and stay away from those worthless dynos.

 

bingo.

my "297whp" trapped 113.

 

Yeah, I know that this particular dyno has been known to read between 8 and 12% low. So call it 10% if you want to average it. I was mostly posting it up to show the gains stock vs trifecta. I'll be hitting the track soon and we will see then.

 

Nice.
Here's an online calculator:
Horsepower Design Equation Formula Calculator - Engine Horsepower Trap Speed Method

If we assume your car was 3200LBS with driver and 113 MPH, we get 360 FLYWHEEL HP. That's about 316 WHP if we use a 12% drive train loss.
Here we go..if your 297 was a MUSTANG #, then that's 6% less than calculated 316 WHP (like dynojet). Pretty close to the 7% factor I've stated here. I know 10-12% less has been thrown around for Mustang Dyno but I really think it's closer to 7%.

 

That was a dynojet though, but I see your logic..

 

I'm sure Vince can get a few more HP our of the car. Just email him your dyno log and he can make some updates

 

I am going to say that it's not a heart breaker and that's the number you will put down on a dynojet as well. Was the dotted lines a stock pull? If so you out down 230 stock which is right in the norm ballpark.
