Quick update on the supercharger progress…
It also came with a special belt tensioner bracket that mounts onto an existing power steering mount bracket (of which I didn’t have, but was able pick one up 2nd hand for around $50). This all bolts onto the existing engine mount point for power steering and keeps the belt tight for both AC and the charger. Note that the idlers are brand new MX5 cam-belt idlers which apparently work fine.
I had to grab quite a few bolts & fasteners from the local supply shop – a quick 15 min chat had me all the correct lengths, sizes and types. I love the little black hex head threaded screws – looks really pro!
I had to grab a 2nd accelerator cable that runs from the 1st existing throttle-body and heads over to the 2nd throttle-body mounted to the back of the charger. By keeping two throttle-bodies you ensure 1) that the throttle volume of the intake to the engine is small (easier idle and throttle response) and 2) keeps the charger in a vacuum when not needed (off throttle) and so keeps the engine load minimised (the charger doesn’t work so hard when turning blades in a vacuum!).
More updates to follow.
