VW AMR 500 Supercharger in 1970 Bay - Second Idler pulley / Stalling on boost
Stock 1600 twin port supercharger conversion in my early VW bay bus that I am developing as a kit.
In this video I've added a second idler pulley to help with the belt slipping. Whilst the belt is not as wobbly as without it - it's still not a great fix. I will need to look into a spring loaded pulley arrangement to make sure the slack is kept out of the belt
Another thing to note is that the engine seems to want to stall when it comes on boost, not too sure what the cause is. You can see it in this video when I open the throttle fast - the boost increases and then the engine wants to stall. If I open the throttle slowly the engine will pick up speed no issue.
