Im running a T88H-SPL on fully-built engine, compression set at 7.5:1, GarageGT 272 Prototype Cams

What would be an optimum comp. ratio to run higher boost levels without sacrificing low-end power and spool?

Thanks

It depends on the fuel you are going to be running.

Will be running race gas..104 or higher. We'll be able to boost higher than a 8.5:1 ratio engine at the same octane, but how much sacrifice? how much do you lose from lowering the compression and how much do you gain from increased boost?
any dyno results anybody???
