Lowest stock GT dyno yet! 299whp/309wtq::updated w/ new dyno typical results

Here is the graph. It was with 93 on a Mustang dyno at 60 degrees ambient. In comparison in 2009 when I dyno'd my GTI, it dyno'd at 233whp/280wtq at the same location but at 50 degrees ambient. Oh yea and 1,550 miles.

Go ahead and discuss lol.

I know the numbers are low. However what concerns me is the hp/tq curve is much different than what i've seen in other dyno's. I will be going to a dyno jet just to compare and see if it gets more "normal" numbers. I asked them to do a wideband however they forgot. Good thing since the place with the dynojet includes it and doesn't give price without it.

Also hp falls off before 6500 as well as 5th gear tops out at 142 before it hits the limiter :shrug: I also can't get the track app 0-60 to complete without a shift to third gear.

They did runs in both 4th and 5th. The hp pretty much stayed the same. I think the graph is of a 5th gear pull but I am unsure, it could be a 4th gear.

Edit:: Ok redyno'd at 4250miles

run 1 4th gear: 377hp/351tq
run 2 4th gear: 379hp/352tq
run 3 5th gear: 387hp/374tq

Correction factor off by 15% or something? lol!

With the PP, I can't get 0 - 60 without a shift to 3rd either. Seems to be perfectly normal for the 3.73's with the aggressive 1st gear ratio. There does seem to be something up with this dyno or something, though. I posted mine in the photos/videos forum and I got 377.83RWHP stock, a very considerable difference.

what the hell? something wrong there.

yea that's what concerns me. Both extremely low, curve is a little screwy, and tq is higher than hp :shrug:

Yeah, something's screwy with your Coyote or they muffed the dyno run.

What are your 0-60 and 1/4 mile times showing on your computer? Or if you have some real runs to compare....

haven't done a 1/4 yet but the 0-60 is skewed due to the extra shift needed. only time I got it to work "right" I had a bit of wheel spin and had to shift into 3rd. but 5.5ish seconds if I remember correctly. I haven't really gone anywhere to solely mess with it yet. Only messed with it for a couple minutes one day.

After the dynojet, I'll take it to a drag strip sometime and see what i can get and maybe let a fast driver take it for a pass as well.

5.5 is pretty slow..You should be around 4.4-4.7 in this season of the year

Yea I know it's slow, initially I blamed the wheel spin and 2nd shift. I'll drive somewhere tomorrow where I can really play with the track apps. Too much traffic around here to even play with the 0 to 60 app

On these pirellis, what psi should I run them at. There at 32 which is the oem pressure if I remember correctly

32 is where I kept mine.

Did you look under the hood? Make sure it's not a v6 with 5.0 badges.

I'd take that car directly back to the dealer. There are issues with cam timing on some cars. Inside source

Mustang Dyno is known for breaking hearts. They always read low I wouldn't be worried at all. Remember they are a tool first and foremost.

Any wheel spin will kill 0-60. The drag strip is the best way to measure power.

Lol, yes but this mustang dyno is 50 less than other mustang dynos haha. Also the tq is higher than the hp for some reason. If you can explain that, I'm all ears

And agreed on the 0 to 60
