TitaniumTT's I hope I make it to DGRR '09 Build

It's kind of a scary thought but entirely possible that too conservative can pop engines. If exhaust gas is sneaking by through the overlap, the intake port is now open adding more fuel to the fire so to speak. Add the backpressure created by a turbo and exhaust gas is now being forced into the combustion chamber. Personally, I don't think you'll have any problems at 11.5. But there is such a sweetspot where these engines like to run it's frightening. @ 13.5 you can warp Apex seals under high enough boost
