ok i dont know if i ever asked this before but here goes....i have a 4 mil stroked shee, aggressive trail port, case port matched, 35mm air strikers v forces, and curently running about 175psi in 60-80 degree weather @ sea level-800 above.....my questions are 1. what comression would i need to go down to to run straight 93 octane pump gas? 2. what will i be losing going down to that compression? 3. also what would i gain if i went up in compression and how much is the max i should go if i went that route? ..... race gas is getting to dam expensive for me to go ridding for 6 hrs at a time but if its going to cost me major power ill deal with it.......thanks for the info guys
