Nothing too exciting but good to document. The belt I first got for driving the supercharger was the cheapest I could find at the time in case it was the wrong length. It had also had a pretty hard time in the early days of running the supercharger while I got the pulleys lined up […]
I think it might be finished or at least as finished as any project can be. I had a bit of a move around of gauges inside. I found having the wideband gauge low down a bit of a problem when trying to catch a look at it to keep an eye on fueling while […]
When I built the supercharger setup I decided to use a cheap recirculating single piston dump valve to vent boost when coming off the throttle and stop the charger boosting at idle. I chose this over a buttefly valve as fitted to the original Mini supercharger setup for two reasons. Firstly the dump valve was […]
