I have one in my buggy. It is second hand, but I'm amazed at how good this engine is performing so far compared to my previous (HB .26). It starts so easily. Idles perfectly and is insanely powered for bashing. I don't know how good it would be in a truggy though, which is a lot heavier.
As for the comments on engine temps. I thought that engines run hot when there is more friction due to them running leaner with less oil passing through.
I'm not convinced that running with a cool temp of say 190 F would cause excessive wear. If you run it in the freezing snow though that's a different story.
I am not going to rebut that comment. I will just highlight and let some other racers chime in on it. Somehow I doubt anyone would agree with you but sometimes its best to just sit back. Let others prove or disprove my comment on running your engine below temp.
Can someone convince me then. Has a proper study or research article ever been published on this? I would like to see it. Isn't it the case that friction wears the engine out? Is there more of this at a higher temp (i.e. less oil lubricating a leaner engine and so more heat generated by friction) or is there less friction at the higher temp due to the piston liner expanding.
One thing I've found is that glow plugs seem to last much longer for me at lower temps (190F), which is adding up to a significant cost saving.
