I have just bought this VGS system of triple IDFs as made for the E21 320/6. The only info I can find about it is in the below link:
http://www.bimmerforums.com/forum/showt ... interested
"A small company called VGS racing or VGS performance (something along those lines) teamed up with Alpina and created a manifold, and linkage, and modified the carbs a bit. Apparently 13 of these were made for German hill climb 320/6 e21's". So this is one of 13 in the world."
Does anyone on here know any more about this type of system and its special history?
Can anyone translate the article in the link?
Unfortunately mine is missing the air intake plenum
