Actually I thought I was posting on the Nitro Engine Off Road forum.(my bad) I started out racing nitro on road. To me turbo plugged engines on-road or off-road have a much smaller tuning window than a standard plugged. A standard plugged engine will run on a sloppy tune, a turbo plugged with the same tune would cut-out. Maybe a hotter turbo plug would have made it run
better, but it was running alittle hot and I think a hotter plug would have made it run too hot. Mostly all todays off-road engines are turbo. I think I seen a dyno test awhile back in a R/C magazine turbo v standard showing a very very slight HP gain in the very extreme top-end, but a slight mid- range lose.
