Well... I'm not thrilled and I'm not upset but it is what it is.

Mustang Dyno
88 degrees (approx)
68% relative humidity (approx)

Baseline w/ Injen CAI, DC Headers, HKS Hyper Exhaust and V-AFC (tuned)

Max Power: 197.1
Max Torque: 132.5

Run @ .5 bar (7.25 psi)

Max Power: 245.7 Increase of: 48.6
@ 8500 rpm
Max Torque: 175.4 Increase of: 42.9
@ 5750 rpm

Run @ .6 bar (8.70 psi)

Max Power: 254.5 Increase of: 57.4
@ 8500 rpm
Max Torque: 170.9 Increase of: 38.4
@ 6500 rpm

From reviewing the data sheets, I believe that the stock clutch is in fact slipping although the tech said he didn't think so. The reason I think it may be, see the below data:

RPM Torque
5700 164.78
6000 157.74
6300 162.60
6600 170.18
6900 166.61
7200 164.12
7500 167.59
7800 166.38
8100 163.72
8400 159.04
8700 151.14
9000 146.50

Now yes, the first drop is right after VTEC engages. But what up with the second? The Boost is constant at that point. Regardless. My pulls were also done with the CEL / MIL light on because my primary HO2 sensor is dead. This is also taking away power. I'll have the new HO2 in within the next week and try to get to a Dynojet just to see what I can put down.

Since I was on the same dyno just before Larry, I would like to throw out my results for speculation. The baseline was just a Comptech CAI. The second run is with a Comptech SC, Neuspeed catback and Denso IK24s. Shouldn't I be seeing bigger numbers than this?





The blue line is boost and it peaked at 6.1 psi



The car does not have a VAFC and I won't put one on until I am sure everything else is working as it should.

TIA for info.

Y'all need to stop using Mustang dyno's...just too hard to compare to the rest of the performance community that is standardized (mostly) on Dynojet. No one will ever truly be able to say what this equates to versus all of the other dynojet dyno's that have been posted.

 

Funny you should mention that. Check this article I found out. Very good tech article!

Not my point. If everyone is comparing oranges to oranges, they can see a 10% gain. If you compare a 10% gain on an apple to a 10% gain on an orange...you've done nothinig. Even if everyone used a dyno that doubled our HP, and gave a completely innacurate reading...at least we'd all be comparing the same things to eachother. That's all. I just don't think Streak's question can be answered unless he compares his car to other dynos on the same dynomometer type.

 

Alright, I'll buy that. I'm heading out to a Dynojet early next week after I replace my HO2 sensor. I'll post those when I get them.

Wes-

I ran on the same dyno for the baseline and the SC. I went from 199 to 229. That's a 15% increase. That seems very low to me.

Actually... My real goal is the speed trial runs. I was able to hit 137.xx on the 1 mile track with 197.1 Mustang Dyno rwhp. Now I'm hoping to hit somewhere in the 160 range with my new numbers.
