That is prefect compression for boost.
Because it will make more power! That low compression shit is a myth hell my bikes are over 12.1 and they have no problem with boost.I've been told from just about everyone 9:1 or 8:0:1 is the better compression ratios to go with.
why is it you think 10.2:1 compression is good for 10lbs of boost????
The first one was e85 this one is pump 91Im at 9.8:1 on stock internals and have would have no problem with running 91 if i had a baller ass ignition system. You do need to watch out for detonation. If it does do that you will need to back the timing out like Conner said and use something like E85.
Question for Art though, what fuel do you use in your boosted bikes? Higher than 91, mix or something like methanol?
Why run lower compression to just have to run more boost to make the same power? Boost=heat. Run lower boost with higher compression and make the same power as low compression and high boost. But have way better off boost driveabiltyCall comp tech line and give them your set-up: comp ratio, heads, weight of car, etc.. and they will give you your best options. Go with the bigger head option 210 cc and a 76 cc combustion chamber. If you lower the comp ratio you will have more room for higher boost numbers. Why did u go with a 5/7 rod when you could have gone with the 6 inch rod and had better rod stroke. Are you going to stay hyd roller on the l98?
