[QUOTE="superpsd, post: 1041370, member: 15821"] The way it is driven currently is staying. I may also look at building a pulley system to drive the blower faster. Currently my 2.7:1 ratio pushes 1312.5L of air @ idle and 6450L @ 3500. When I had the larger pulley it was a 2.25:1 driven setup. I picked up 292.5 blower rpm @ idle or 650 rpm. At 3500 rpms it picked up 1575 rpms to a maximum blower speed of 9450 rpm. however the maximum safe speed of the blower in oem form is 14,000 rpms. I would need to spin the blower with a 4:1 ratio which I may go down that road. The other option like I said which will happen either way is a larger Whipple. A larger blower with push more cfm at the same blower ratio. Not to mention more efficiently. Twin screws actually have internal compression a roots does not. Next step will be to install a free floating bypass to allow the turbo to pull from atmosphere when the blower is not pushing enough air. This blower alone has a lot more room to spin it faster for more performance. I may mess with it or just wait to buy a Whipple. [/QUOTE]
