My first dyno run

[gmac708]

I finally got my Z tested on a dyno this week. I had Corey at Slowmotion Motorsports set things up for the pulls.



Dyno attaches to wheel lugs. Pretty slick setup.



Engine is basically a stock RB26 with FMIC and an open 3 inch exhaust. Running on stock ECU, 9PSI boost.

Here is video of the pull on you tube.

It was 359 WHP, 283 WTQ. I am very happy with that.



What concerns me was the AFR. The numbers are too high for my comfort. Here is what we got from the wide band clamped to the tailpipe.
It should be in the 12's.



I was wondering if the tailpipe method of measuring the AFR is fairly accurate. I'm thinking of putting a wide band in the downpipe and seeing if it makes a difference in the AFR numbers.

Nice Gord, I have pretty much the same setup and was putting down 300tq, were loosing the clutch so I have to go back and tweek it. HP was saying 300 too but that doesnt sound right. I have my afr in the 12.3 range. Get you a AEM or a haltech

Stock turbos.

Get you a AEM or a haltech

Or Nistune. I was talking to Alex about fuel pressure as well. I still have the stock fuel pressure regulator in the fuel rail, and I am running another fuel pressure regulator in parallel. I might try and getting rid of the stock one and just go with the remote one on fender and crank up the pressure a little.

Yea i had a hondata on my honda, which is pretty much the same thing as the nistune, or was... It did good. If you track her alot the AEM might be better sooting in the long term. But it takes the long term to pay for it too. lol. If you go that route hit me up i can set ya up with a basemap.
