Perfectly understandable given your situation. It seems that such behaviour is unavoidable, but its like all things thorough-bred; they are twitchy, tempromental and at times unreasonable, but awesome at full tilt. I'm like that too and as stated by someone else, my car is not modded nearly to the levels you have. I suppose I'm nearer Stephen's level, especially the gearbox. I worry about it breaking, however, I can't see my avoiding track days for too much longer. The thrill is too great and if the car breaks then I'll worry about it then. Hopefully I'll be able to source the cash for a 6-speed in due course, and who knows, if I win the lotto, I'll install some PPG goodies!
I have noticed my oil temps creeping up to 102Degrees under normal use - any ideas why that is?
