    From watching this series and looking at the rules
    some of the specs on this thread are not adding up.

    R/p is 7:31
    Internals are regulated
    Rods have to be 550 g or higher
    Crank has to be 13.3 kg so basically a cw 66
    No titanium of any kind, including valves and springs.
    Porting of heads is minimal.
    Looks like flywheel, clutch assembly is free.
    Cams are free.
    Pistons free but compression is limited by fuel and single plug ignition. So what 10.5:1??

    With all that said I can't see 9k rpm and in videos I only see 7500-8000 rpm. I heard 220-250 hp but with these specs I can't imagine much over 200 hp mark.
    Also remember you are limited as ignition is stock.

    Anyone have any insight into these cars. Also suspension set ups? There is not much you can do. All spherical bush but even spring plates are stock. Not much camber adjustment on early cars (Late 65 build would be ideal for front camber adjustment) so it leaves you with sway bars (solid non adjustable) and Torsion bars?
    Anyone have thoughts?

    Cheers
