Can't seem to find any difinitive word on the HF's particular cycle (Atkinson/Otto) |
This doesn't make sense to me. Why would you have detonation problems at low rpm without a supercharger, but with a supercharger you wouldn't? When you apply higher cylinder pressures is usually when you see more problems with detonation.
I can definitly see why the electric motor works, but why supercharger?
