A lot of my research on afrs lean of 14.7 has sparked an interesting question.

At a recent ricer meet I had an argument with a kid about fuel cut (rev limiter basically). I have my rev limiter set at 8k instead of the stock 8.3k so that in first if I bounce, its safer. Basically he was telling me that fuel cut is bad b/c a little fuel is still burned, thus resulting in a lean condition which is bad. I tried to tell him that fuel cut means no fuel = nothing to burn = not dangerous.

He insisted that there was some fuel, and that Id "blow it up". Which brings me to my next point. I know that nobody is dumb enough to try this, but I'd be willing to bet that if you tuned a car WOT to leaner than 16:1, nothing would blow at all, the car would just run like crap.

My reasoning behind this is simple. People hear lean and automatically think "higher temps", but this is only true to a point. As was proven in another of my posts, EGT's actually go DOWN lean of 14.7:1. Furthermore, in the 16-17:1 range, there is very little fuel as compared to air, making it seemingly impossible for the explosion to be more violent than one closer to 14.7.
