Any pictures of the bracket and pulley set-up?

I heartily endorse this product or event.

I'm really interested in the pulley set-up. I've got mine about 50% finished but haven't given any real thought to the pulley situation yet. I really wished these cars used a single serpentine belt.

We modified the bottom pulley and added a multi rib pulley to it, then ran a multi rib belt off that to drive the charger, i will get some better pics of it later.

we also machined the bottom pulley on the front to rub a 60-2 trigger wheel using the standard sensor.

Awesome, so this is on a high compression euro motor I'm imagining? I just put a high comp in my car, and although the increase in power is really nice, i want boost. Was wondering how it would go with high compression and boost.....

yes its the standard high comp euro engine, the rotrex chargers work well lowish boost on stock compression ratio.

Nice workmanship. Where does throttle response really show the horse-power?

Ill scan a copy of the graph in now.

flywheel power.

That is a really nice powerband! As expected it looks like a more powerful NA car. It looks like a really clean install. I'd love to see some more pictures of the mounting bracketry and tensioner assembly if you've got them.
