I have built several blower motors in the past. The gentleman that taught me was a retired nitro racer. His view was, for a street blower engine, you wanted to actually use the blower. He said since they were so expensive, he liked spinning them. All of the engines we built had between 6 and 7:1 compression. His opinion was with SCR that low, there was no need for boost retard, water injection or any of that stuff, plus you could run the blower either at 1:1 or overdrive it a tad. He always said why retard the timing or spray water in it? Doing those things effectively puts the fire out. All of the engines we built ran very well. Those on the lower SCR side could run on regular, but the 7:1 motors needed premium. I guess he figured if you're gonna pay 5K for something, use the hell out of it. I like how he thought. May he RIP.
