I THOUGHT OF THAT,BUT MSD SAID 45 TO 50,WHAT WOULD BE THE REASON OF A SMALLER GAP?
High cylinder pressure can "blow out" the spark if the gap is too large....maybe a poor way of wording it.
WHAT CAUSES HIGH CYLINDER PRESSURE?
Higher compression, Nitrous, turbo, blower, cam timing....whatever. That's the whole point. The more air you can pump through the engine the more power it will make..think of an engine as a big air compressor. An engine with 12 to 1 compression has 12 times the amount of air in the cylinder at BDC as it does at TDC..The more air you get into the cylinder on the intake stroke the more cylinder pressure you will have when it's compressed, therefore more power on the power stroke. Again, maybe poor wording because valve timing effects the cylinder pressure too but that's pretty much how I think of it.
