Alternator is now relocated.
This is the adjuster i built. It works kinda like the OEM one, except it pushs the alternator up instead of pulling it up. I used a $2 150mm M8 bolt from bunnings, and welded up a lower knuckle for the bottom pivot, and made it captive on the bolt by welding a collar on. That way the bottom spins freely in the bottom knuckle and the top knuckle has the threaded adjustment. Seams to work mint. But real test will be at the track at 7k rpms.
And here it is assembled. Used a common (cheap size) belt from repco. Had to make 2 trips to get the right size. First belt i got was smaller and cost $11 more. This one must be vheaper because a common sizing? (Yes used trade pricing on both belts too so its not that.) Phitos doesnt show it, but it leaves ample space for the IC piping to come across and meet the throttle body.
