If i had time to do this i would have, glad i could help encourage the project. Great job!

And if anyone is thinking "what about cog belts on the supercharger side". DO NOT TRY THIS. I went through 2 belts and 2 weeks of headaches. It will never be reliable enough to run. The setup back there just wont allow the clearances you need. The extra pulley is where we really need to put the grip down anyway. However, i will say the sound that came out of the cog setup was very intoxicating to say the least. Reminded me of my old positive displacement eaton blower on my 350Z. Wish i could have gotten it to work.
