[QUOTE="DMotorsports, post: 11224304, member: 113666"] You'll get at least 10 different answers on this one. Here's my 2 cents: just keep in my mind that as compression and boost go up, you'll be flirting more with possible detonation. If I were building an engine primarily for street duty, I would go with something in the 9:1 - 9.5:1 range. On the other hand, if I were building something strictly for track use with race fuel, I would [I]probably[/I] go with something around 10:1. There are guys that run even higher compression than that and put down some very impressive numbers. However, you'll have a difficult time convincing most engine builders to go higher than 10:1 on one of these boosted engines. They have their reasons.... [/QUOTE]
