I have raced my 10.? to 1 (supposidly)408 on pump 93 ,87 with 104 added ,and 110 Sunoco.It runs the same ET's on all three.I use 110 Sunoco now mainly because i like the way it smells over pump gas ,and like was said earlier i dont worry about consistancy of fuel or detonation.Mine is a drag only car that i dont race much and i dont use enough to make much difference in $$.I found a local station here in my town that sells it to the dirt track guys .Its 5.99 a gallon at the station ,lots cheaper than buying it at the track.I dont think you will notice a gain with your compression level either ,but thats not the only reason to run it IMO...
