What is the draw back of running slightly higher compression with a blower. For instance lets say you had a blown BB with 8:1 running a blower 20% over, how would that differ from a blown BB with 9:1 running 10% over? The reason I ask is I was doing some quick math and I think our new 540 is going to have about 9:1 compression, based on the pistons and heads we are running (SRP -9 dome and Brodix BB2's). We plan running gas, will this cause a problem? Keep in mind this is a dragboat that will get very little use, with no prolonged cruising (how far can you go on 5 gallons of C16)
