Overlap in the low mid-range is your friend, it helps get that turbo spooling several hundred RPM faster, especially given the fact that a turbo will flow enough air to maintain a given PSI in the intake manifold, what happens if some skips the cylinder while both valves are open? It hits the turbine and keeps it spooled, so it will still maintain the PSI, and wow, you don't drop out of boost... What's the downside again?
Do you know what mostly spools the turbo? HEAT! THere are 3 things that show energy in a gas: heat, pressure, and volume.
The turbo's exhaust wheel is specially designed. I will first explain that at the end of the combustion stroke, combustion is still going on which raises pressure as the piston pushes it out. And I would think an exploding gas would have more pressure than say 10psi of boost. Now does exploding/exploded gas have a higher temperature than say compressed ambient air? Now would 0.45L (1 cylinder's displacement) have more energy then a small leaked amount of boost?
With that said, you saying that the comrpessed air will spool the turbo is like saying You can spool a t88 on your teg like it was a t3. That leaked boost will almost do nothing to spool the turbo :fawk:
