k man im basicly running a stock a6 motor w/ z6 intake manifold and boltons so i'll be at about 8.8:1 compression using the stock p28 pistons so it would be slow as balls with out nitrous and with the pm7s im sitting at 11.4:1 i'd like to have some power off the bottleso youd rather lose 25 whp from spray and gain maybe 5-7 from high comp? your math is backwards
