Clutch has now decided after a few launches of dropping the clutch at 5k rpm to start to give up so its engine and box out, new clutch, maybe a OSgiken twin plate, and head gasket change. i got a Cometic metal head gasket and ARP stud/nut to fit, + the head will be completely rebuilt, il re shell the big ends when its out, well why not?
So sometime after Jae il get busy and then i can up the boost to 18 psi, maybe even 20 but will have to see how the fuel system copes
