Did 3 pulls today on a DynoJet with the following #'s:

1) 420hp/476tq
2) 424hp/441tq
3) 437hp/457tq

62 degrees, 39% humidty, car pulled a solid 1 bar and peaked at 1.2 bar

Cars AFR from 3500 to 6500rpm was pretty much 11.9-12 AFR

I will try to post the graph later

Car has the following:

1) UMW Stage 2 Turbos 16/24 Hybrids
2) UMW DV's
3) UMW WasteGates
4) UMW Tune
5) OEM Ported Headers
6) SpeedTech Exhaust
7) 5 Bar FPR
8) Vivid AirBox

Is that low or am I mistaken?

 

Dunno, it pulls very hard and runs great.

Christian

 

At one bar thats pretty normal... had he been at 1.2 bars constant then the numbers may have been better.
was it RWD or AWD dyno

 

RWD^^

Christian

 

Are the 16/24 hybrids supposed to make more power than k24's, or do they just reduce lag?

 

Sounds low for those mods on a Dynojet RWD. Did you dyno before the mods?

 

I would expect higher numbers

 

Christian,

You are on the right track with some good "goods".
Hook up with Whoosh, he is a gem.
How does it compare with your 92 turbo? RWHP?
Side by side pulls?

Christian,

I would like to see your dyno charts before jumping to any conclusions. I can tell you that cooling is an issue sitting static on a dyno. We use SEVERAL fans. Also my guess in your UMW programming is pulling back timing, especially if you are not getting enough air to the intercoolers and intake. Mine would do it on the Dyno and not on the street. I added 104 unleaded (about 2 -3 gallons) on the dyno and what a difference. My runs went from about 428 rwhp with pump gas to 458 after adding a little race gas, repeatable over and over. There is no way to replicate the airflow available at even 40 mph on the street in a typical dyno shop. This is why your car runs better on the street and feels strong. You should also check to make sure the "Premium " which I am guessing is 93 since you are here in TN, is not a Ethanol blend. If you asked for a 93 flash from Kevin, that is exactly what you will get. His software immediately pulls about 10 degrees of timing out if it detects any condition that could lead to detonation. Static air on a dyno and gas with ethanol are two sure fire ways to get your timing retarded quickly, and safely by Kevins flash.

With your K16/24s, aftermarket exhaust, and intake, I would expect higher numbers than you are getting. My car has the stock K16s, UMW Flash, and my slightly modded stock exhaust and it pulls 459 as mentioned above on our Dynojet.

Please post your chart so we all can see what is going on.

Here is the fan set-up we use.


or like this without the stools on the side for the intercoolers, both showed the same approx hp



Cool down for 5 min after every run.

Your other option is to cruise on up here to Nashville and we can do some side by side pulls (on the closed off track of course) since we both have UMW and some exhaust mod, the K16/24's should be the difference. Would be fun to see. I recently ran the 60-130 (mid 9 sec only tried twice) in Houston and your time for that would be interesting also.

You also did not mention if you still have a stock clutch, surprised it is not slipping yet which would also show up in your dyno charts.....

Christian, Your build is identical to mine, except for the vivid box. The numbers seem very low to me. I'd have expected numbers above 500WHP.

Mike

 

The dyno doesn't seem to be doing your setup any justice. Perhaps you can log some 60-130 runs?

 

I will post the graph later today.

Christian

 

I agree with Mikelly if everything is working properly. (Holding boost, no slipping of the clutch, enough cooling fans, no timing being pulled, and enough fresh air circulating around the intake area)

 

You should solid 1.2 most of the way. I think you'll see MUCH better numbers with a wastegate upgrade or adjustment if you have the upgrade.
