The car hit 48mph today with a medium glowplug. I swapped in the hot glowplug again and it made no difference. In my mind, that means increasing the compression further would have no beneficial effect. Does that sound right?
The engine temperature was cool, around 210F, but I don't want to go higher than that because I've been running in cold air and the engine is going to run much hotter when it's 90F outside instead of 45F.
what pipe and manifold are you using ? do you have any tuning options for manifold ? quite often I have to trim the buttons on the engines I modify just to get them as tight as I need them.
