Lowest stock GT dyno yet! 299whp/309wtq

15 Magnetic Mustang PP GT

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 when it hits the rpm limiter

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.

Something is either wrong with the dyno or the car or he dyno'd in 6th gear lol.

 

[DivineStrike]

haha, 6th gear. Nah I was there it was both 4th and 5th. That would be an interesting dyno though...ya know spinning the wheels to 220mph or whatever 6th theoretically tops out at.

You don't need "wideband". Just datalog it. The on board wideband will give you all the a/f data you need and then some.

I don't have any equipment. How would I go about datalogging it? I'm definitely going to get it dyno'd at a regular dyno jet just to be sure it's not the Mustang Dyno shop being odd.

OP:

a) Immediately go to another dyno and get your car tested again
b) Immediately go to a dealer for a full check up if you get the same results

Yea that's what I'm trying to do. However the shop I called didn't any openings till Wednesday. So I will have to wait till next Monday as I am traveling to Hawaii for a few days.

Ok brother, let us know what happens!

 

[SID297]

That's an import shop with an AWD dyno. It's hard to tell what they had the load on the dyno set to.

 

[dmichaels]

wow that does seem very low, hope it's just an issue with the dyno, it's also a bit strange that the torque is higher than the HP

 

[SID297]

Also, without datalogging you have no idea what the ECU was doing. It could have very easily went into cat protection mode.

 

[Ubergeist]

Wow, surprising.

If it makes you feel better, my 2006 Mazaspeed6 with a catback put down 225whp on a mustang dyno, and my 2001 CLK55, bone stock put down 263whp

 

[manolith]

What I would do.. forget about dynos. Go to the track and look for a 111-112 mph trap speed. If the traps are there I would go home drink a beer and think about what to do to go faster and that 435hp are just not enough.

 

[Blown2004Stang]

Further proof that a chassis dyno is nothing more than a tuning tool..

 

[DivineStrike]

Yea a drag strip is next if the next dyno doesn't show anything more normal. I will try to datalog my dyno if I can.

I did a couple test runs with the track app and my trap speed was 107. That was not giving it a hard launch to make sure I didn't get any wheel spin. No missed shifts

 

[Mystic_Cobra]

You need to put it on an actual Dynojet and post numbers with SAE correction.

 

[Mach828]

Ya, get it on a dynojet and post the SAE numbers.

 

[Sam@Coastal]

Do you have any idea what the operating temp was when you made the pull?

 

[DivineStrike]

Operating temps were normal. Before the dyno I was able to let the car cool down for 45 min or so with the hood open

 

[SCalla1384]

Go to the track. Trap will give you a much better indication of power then a dyno will!
