Today I got my car dynoed at JBA racing in San Diego. I am a little skeptical about the numbers, they seem a little high.
Temp-60.5
RWHP-291.4 at 5965 RPM, Air/Fuel 11.6
TQ-299 at 4474 RPM

The only mods I have are flowmaster mufflers that are designed for the previous gen. mustangs and steeda udp. I told them that I thought 05-08 Mustangs are putting 255-265 RWP. He told me that is about right.

wow sick man thats some nice ponies for minimal mods. Now do long tubes and an o/r h pipe.. Then comes the blower!

JBA uses a dyno dynamics instead of a dynojet. I have read that dyno dynamics read higher and I have also read that they read lower.

 

[leebunnyz]

they read lower, dyno dynamics has more accurate hp numbers.

Dyno Readings are all in the Calibration File.

NICE numbers!!!!
I got 7 RWHP from the UDP . I had it dyno'ed before and after the UDP install! I started out at @ 245 RWHP and 260 RWTQ Stock. I have made nice gains ,check my signature , I am happy

One thing I noticed is according to the A/F numbers, I am running too rich. At WOT I am at 10.0. Wonder if there is indeed something wrong my car or the numbers (RWHP,TQ, A/F) are off.

 

[Trick Tuners]

If anything the hp will be a bit lower with such a fat AF.

 

[gragra73]

There must be something wrong with their system. I will get another dyno at a differnt place this Saturday.

To see if those numbers are accurate, go to the track

I would hold off on that(re-dyno).... if you are going to do something more to affect your HP then wait till you make some changes... who cares if it is a little off for whatever reason... you have a nice dyno from a good shop..

I had my car dynoed again from another shop. They used a dynojet and SAE numbers.

HP: 285.91
TQ: 287.36
Airfuel seems normal now. It read 12.5.

Maybe my car is a factory freak.

JBA always reads high .. the one in SD is known for it.

no that sounds about right on a dynojet. a stock s197 will read 275-280whp on a DJ.

 

[gragra73]

An 05 auto ran 263 HP and I around 265-270 tq.
