Devils Lake, ND | Forced induction motors, especially gassers, don't like a lot of intake/exhaust overlap; you just blow your boost out the back. Detroits are different, in that they need the boost to push the exhaust out of the cylinders. Their "overlap" is determined by the position of the exhaust ports in the sleeves.
More boost should help a 318, as you can still pack the cylinders after the piston gets above the exhaust ports. On a puller, I would prefer to speed up the blower (if that's possible) rather than add a turbo. The turbo will slow down exhaust scavenging. (I know the xV92's have turbos) maybe jerry-rig an aftercooler of some kind? | |
