Latest developments on the car front. I was hoping it would be a dyno success, but it turns out there is still some work to do. Anyway, it sounds nice with the headphones on! Edit:- When I’m using the O2 sensor I put an extension pipe on. I know it wouldn’t work very well without it ALSO, I've found a serious restriction in the intake system, so I've sorted that, so just need to do something with the slipping clutch.
