Just got back from having the teener run on a Dyno.
Good and not as good as I expected. Was hoping for at least 100 Hp, didn't make it. This run was on a Mustang Dyno, allegedly a Dynojet Dyno reads from 12~15% higher. First the good. Runs were extremely consistent. the three runs printed pretty much right on top of each other. Torque was way up there above 95 tq from 3000 to 4500. with no real dips. HP numbers were very consistent with a nice smooth line from 2000 to over 4500 Now the bad Max HP was only read at 88 Hp and max torque was 100. If I add the 12-15% it comes to 100 Hp. But it is what it is. Build is 2056 D-jet, Heads by HAM RS+, 8.6 comp. Raby 9590 cam, SS HEs with Triad muffler. I Have adjusted the MPS to what seems to run best for this car. This car runs great and I just wanted to know what it was putting out, Not really planning to try to tune it for more power. Reliability is the key. and I am so far happy with that.

I always use Dynapack. It controls the inertia/rate of acceleration, eliminates variances in wheel/tires size/pressure/grip, and measures the torque directly at the driving wheel hubs.
It's the only dyno we use for our racing/tuning programs. |
