2010Black_Stealth

So I just had my car dynoed for the first time since I had all my modifications done and something just isn't adding up.

While doing research, I learned a stock 2010 GT puts down about 276 HP and 281 TQ to the wheels.

So it was quite the surprise to me that with my modifications, I am only putting 310 HP and 304TQ to the wheels using a DynoJet.

List of mods are:
FRPP Cams
FRPP Throttle Body
JLT Series 3
Pacesetter LT with O/R H
Flowmaster Outlaws
Bama 93 tune

Is this normal? I have been in contact with Bama @ American Muscle and they have been great with helping me.

But wanted to get the forums take on all this. Thanks all for any help

That's pretty damn good numbers. BlackSmoke (another member here) made about the same numbers on hi '06 with the same mods minus the throttle body.

My '07 on a Dynojet made 275hp/293tq ot the wheels on a Dynojey with JLT series II/Brenspeed 91/Bassani catted-x. I also have 4.10s so people say that gives a less than true reading of HP on the dyno.

So ignoring that you aren't supposed to compare two cars on a dyno it looks like you're making 40 or so hp maybe more with LTs/throttle body/cams at the flywheel than my car?

To be honest, your TB and flowmasters aren't doing anything and your 2010's additional 15 crank HP (over the 05 thru 09) is from the FRPP Bullitt tune so with your BAMA tune your still only gaining the roughly 20-25 RWHP over the base 265 average RWHP of the 05 thru 09 4.6L. Add to that about 20-30 RWHP for your cams and LT combo and I would have put you at about 315 RWHP; 320 tops. And that's assuming everything is working 100% in concert with one another. Depending on the dyno, the guy on the dyno, the ambient conditions, your fuel quality, yada-yada, numbers can vary. Most importantly, how does it run???

Where in FL? Where was it dyno'd.

Some cars only dyno 260-270 stock.

Those numbers seem low. Can you post the dyno chart? I dyno'ed 270rwhp and 293rwtq stock (except k had 4.10 gears). Your numbers are low for those mods. But, the important thing is how the curve looks. Different mods strengthen and weaken different parts of the RPM range and may make for no peak gains of 40+ but show only peak gains of 20. What correction factor was used?

2010Black_GT1,

I noticed in your profile (on AFM), your GT is an automatic. These numbers are exactly on par with an automatic 3v. Keep in mind that even a fully locked torque converter will roughly have a 10% slip. This is one reason automatics don't make as much power on a dyno as manuals.

Another important thing to note- is dyno numbers are just a reference of power. They can only simulate race conditions and aren't a true way to show how well a car performs. The best way to test that is on the track!

That being said, I think your dyno numbers are awesome for the current mods and automatic transmission! I would be very happy with those dyno results.

Please let me know if you have any other questions or concerns!

I have gotten some great reponses back from Bama @ American Muscle; they continue to surprise me with their great customer service. They have adjusted some of the tunes as it seemed I was running a little lean.

I attached the DynoJet for everyone to see that asked.

Thank again everyone for your responses.

Dyno and Install was done at LaMotta Performance. This is a GREAT shop for install and about everything else related to Mustangs!

Those guys really know their stuff.

Your numbers may actually be lower. The correction factor is standard. When I set my correction factor to standard, on exhaust, 4.10 gears, and 87 octane only, my RWHP goes from 283 to 292 and my RWTQ goes from 296 to 306. I know you have an auto, but I still think there is more power in tuning. Most dynos use SAE corrected numbers.
