One thing you can clearly see is that NMS went up through the gears, would that make much of a difference? |

I made the comment at the time that the fueling at NMS was not as good as we had seen on the road. Also, were we still running the dodgy LC-1 at NMS?

Actually, comparing those two logs in detail, you can see why we did not make the power lower down at NMS. Those massive AE spikes and then running lean on the outers would not have produced the torque. Edited by Paul S on 4th Oct, 2010.

Just a note about our rollers that might help you. The power runs are done via an inertia test. I.e. no load was applied to the rollers. The resistance is just the rollers weight. So the load was definitely not changed from one run to the other. Maybe the engines revved up to quickly to produce the best boost? Chris yes i think thats definately right chris . another thought is , with an su ,theres a delay ,therefore a restriction in the rise of the piston ,depending on which oil is in there , it could be that the run time was not long enough for the piston to get to the top ..ergo ,if you have your wastegate boost signal feed from the plenum ,and yuor datalogging from the inlet manifold ,then the boost will drop due to the piston restriction .. this would explain mine dropping to 17.5 psi at the top end ,and may explain others boost drop . Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

Chris, do you think that you may have inadvertantly done run no. 3 in second gear ????

I've made some slight corrections following Roberts de-smoothing operation. It has not made a significant difference, but the SOT looks nice Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."

Ooh, Robert can I have the data from my runs please. In the 13's at last!.. Just |

I have now concluded that the latest RR data is fundamentaly flawed in terms of using it for any scientific/mathematical purposes.
