That would be one of the best written articles I have seen on the subject, might have to make that compulsory reading for a few people I know who refuse to believe detonation or pre ignition exists...unfortunately because they have to actually read it it will probably be beyond their respective intelligence levels...

Yes they are a little off on their tuning, but I do like your coyote overtaking of that sheep!!! Like a GT on a Corvette...

A very enlightening article. One thing that I hoped he would address, but did not, is the phenomena of an engine at idle that "runs on" after the ignition is turned off. I assume this is "pre-ignition" from hot spots, but it doesn't destroy the engine, as he says pre-ignition will do almost instantly. I further assume this is because the load is so low, but I'm just guessing. What's going on here?

I think I suffered intracranial detonation reading that article:laugh:

Seriously though, thanks for the link.

Thanks very much; really good article. I particularly like the 14-degree "magic number." I'd love to hear a deeper explanation of "why that particular geometry regardless of any other design attributes" but have no idea where to look.

Ha Ha, probably, but they know enough to avoid admitting that their problems were their own doing, the Unicorns horn stuck in the right place might be a useful persuader!
