Banged in a 4 bar fuel regulator liberated from a VR6, checked things over, then put it on the trailer and took it out to the 'Ring at 5AM on Friday.
I did 7 laps in it on Sunday, and a mate did two laps after me.
6 laps on Monday.
It didn't flinch.
Back in the workshop now, ready for over-winter upgrades.
Report and photos to follow in due course.
