This is what I got, when I ran my car in a dyno
http://www.hut.fi/~oruosaar/kappyra.jpg
and for you that are not familiar with the metric system
428.9Nm=316.3ft-lb not bad !
My reasons for complaining are not on the values them selves, but on the mixtures. From the dyno sheet we can see that the power output and torque add up with the numbers specified by SpeedParts.
About the mixtures:
Under WOT (wide open throttle), in this at dyno the engine runs extremely lean (co=2 lambda = ~0.98 @ 4500). One can only imagine what happens if the engine is being run this way. I decided to end the dynorun @ 4500 because obviously the engine was on a destruction path. The values are not based upon one run, we tried several times, with both cold and warm engine. All the runs were identical, when the throttle is fully opened @ 1000 rpm the mixtures starts to sink from like they are supposed to do.
As rpms rises the CO reaches value 2 @ 4500 (lambda = ~0.98), when it should read around 0.85-0.9.
I have tried and tried and tried to get some answers from SP, but now more than three moths later I'm still stuck with a product that wont work in my car.
Davenew:
Have you had your A/F-ratio checked, if not I strongly recommend you to do so.
The story goes on, but I don’t have the time right now to discuss this matter.
