ok, seeing how I ran a bearing at taupo after 4 1/2 laps I'll share my list of mods that I did hoping to make it safe for the track.
Parallel Fuel Rail Setup (aftermarket rails with bigger internal diameter)
Sard fuel pressure regulator, set to 45psi (forcing more fuel in)
Oil Cooler with -8 Lines
5L of castrol edge 10w60
I was driving quite hard in straight lines changing about 7.5k, not pushing it too hard around the corners as still getting used to my suspension setup. I was running RE01R tyres which are ment to be quite sticky but certinaly not as good as semi slicks.
Lost pressure at the same time oil temp started going above 120, I headed back to the pits and as shale says nunganunganunga.
I was running a bigger turbo, a VF36 P20, which flows about the same as a VF22, on a factory computer (V5 sti) using an EBC boost wasn't spiking just hold steady at about 16.5-17 psi.
***modified*** I forgot to mention 138000kms
So when my new engine goes in its getting a Moroso sump, no messing about!
