Re: Sean's '12 PBP ltd - Suspension and Rim/Tires upgrades coming soon
Evo's run a 9.0:1 compression ratio. I don't see why we couldn't run it with the same success.Guys, I've been reading through ThunderRobos journal and taking some notes. He made a good case for upgrading from the Manleys to the Carrillos. Also I noticed he's going with the 8.2 vs. 9.1 for 91 pump. What are your thoughts on this? I've read a little about it and the stock ratio is 8.2. Wouldn't bumping it up to 9.1 make it harder to tune etc?
