taking away fuel for power

[DrLove'sKuDang]

to a point running lean will add power... but what bad can happen if you try and run too lean?

whats the highest you can run and still be safe?

i was looking over all my graphs and previous runs had a 5hp gain in the midrange because it was running more lean.

at 5600, one runs afr was at 13.42 producing 154.02whp. and another was at 14.17 making an even 159. is there any sideaffect to running leaner?

lots, incredibly high combustion temperatures to start out with, pinging and detonation. You can blow a motor very fast running too lean. The key is to run as lean as possible, without risking ANY pinging, detonation or otherwise. You can run a little leaner at the track than around town. Best way to tune for this, is obviously on the dyno

does the safe range change depending on what you have done to the car?

whats the leanest you can run and stay safe?

all i have are cams so it should be much different than stock.
