Just looking at the turbo chamber and piston using your terms Jmac and from what Ive seen so far so can be wrong! but would you say if someone is looking at under 7500-8000rpm its better to have small capacity David Vizard favored chambers as TK uses but making up for the high comp using dished pistons?. The dished pistons are a little heavier but better for heat dissipation and stay strong at these revs while the inlet valve providing it gets enough lift could be better deeper into the head so it creates a funnel like shape for the mixture rather than level with the exhaust valve? eg. creating less turbulence in the middle of the chamber.
Meaning the seats would need to be cut deeper into the head for the inlet only just enough to get a taper there to help the seat.
Here is a basic cross section of what Im trying to trying to convey
blue is the inlet valve deeper set within the chamber exhaust is red
I know there is more to the chamber but just wondering what if atm
as I understand the need to get the mix towards the centre but also
concerned on the combustion balance for that ball shape at tdc
without resorting to the more ideal hemi chamber.
There would be more bias or guided mixture on the outer edge of the
inlet valve while the centre area only has a taper halve the length.
