Hello again
I've just got details from Scat Pistons in their kit.
KB 718 are Flat Top listed with 4.9cc volume
This will bump up my CR a little more... Will I still be OK with this ???
Using CC XFI 280 Cam (69 ABDC) gives
12.42 w 0.040 gasket - DynCR= 9.56 199.89 psi
IF i thicken the gasket I get the following
12.24 w 0.045 gasket DynCR= 9.42 196.16 psi
12.07 w 0.050 gasket DynCR= 9.30 192.98 psi
Is increasing gasket thickness a sensible option or is reducing quench making things worse ?
Thanks
Mitch
