In Reply to: Best Dyno Run Is Usually Not The First Run... posted by dpeete on September 17, 2000 at 23:38:52:

>I have been to DynoSpotRacing as well and have dynoed my car... every dyno I have ever seen for my car or other people from other shops doesn't have the first dyno as the best. The car usually peaks around the 3rd or 4th run on the dyno at which point the heat starts to bring the numbers back down.

Well, put it this way, I've seen other cars on a dyno (mostly Miatas I admit) and run 1 of 3 were the best ones (of course the spread isn't as dramatic as BMWs, maybe 1-3 hp overall). Although I admit, I think the Miatas run way cooler than BMW's on a dyno to begin with.

A guy in this board did an ODB2 car run with the first being the best run before the car got too hot. I'd love to see more dyno charts posted from people on this board.

Am I asking to be proven wrong? Well maybe...

[laughing]

So here's the thing, how does one go about dyno-ing an OBD2 car since it's been shown that the traditional strap the car to a dyno
and run it hard seems to not work so well?

Or is it just OBD2 that sucks for performance overall?

PS going to the next Laguna event?
