RB26 compression ratios, your opinions sought.

[Chris Wilson]

RB26, Tomei 280 degree cams, 10.8 mm lift. TO4Z turbo. Tomei cooling channel 87.5mm pistons, standard stroke on billet steel crank, Tomei (Carillo) rods. Mildy ported head, chambers as yet untouched, on 50mm GTR throttle bodies, stock GTR plenum. MAP sensor only Motec M800 ecu. Intended usage, track car. Head gasket is 1.3mm multi layer steel. Fuel, well, I will have 2 maps, one for UK super unleaded (98RON) and one for unleaded race fuel (112 RON). Engine will be mapped on proper engine dyno, not rolling road.

Opinions sought on best static CR, and onn squish band removal, if removing or reducing the squish helps STOP det then this is the ONLY piston turbo engine I have ever heard of where this helps. I was intending reducing compression by milling piston tops, and was considering between 7.5 and 8.0 to one CR.

Thanks.
