fire slots in piston domes

Post by Troy Patterson »

That would be the one.

Anybody try it or know anything about it??

John conversed with me about the treatment while he was conducting some of his testing.

There was an issue with detonation with as little as 20 degrees total advance on one of the test engines, but I believe he worked this out based on my last conversation with him.

The advantage I have is the dome not hitting the ground strap on the plug.

Here is an idea I'm trying in a Chrysler 2.2 turbo engine. Compression ratio will be about 9.75:1.
