Interesting commentary on spark/boost/etc....

Boost and timing, how low to go?

Does, or should, the reduction in timing based on boost ever get to the point where I need to stop reducing the timing? For example, I'm at 15 degrees at 29psi (plugs look good) and 20 degrees at 19 psi. Does that ratio of 1 degree for every 2 psi carry on at 39 psi and 44 psi? Or is there a...

If that cylinder exceeds your maximum pressure, the plunger moves, completes a circuit, and you know to back off that cylinder. Someone get to work and make some bucks.

How funny that people are now realizing boost is better than timing. I was saying that 30 years ago and people looked at me like I was stupid.

I used to know the Keen brothers. They had a Pro 5.0 car and won a lot races. Their engine builder lived next to a friend of mine so we would be over there sometimes, and I told them, "You guys should switch to turbos and dont look back." They both laughed at me. Now who's laughing?
