Can't really run a cog TPI setup without a bypass valve right?

Running a bypass is a good idea in any supercharged application, And is a must with a cog drive. If you are in need of a cog drive, you are at a point where a bypass should already be in use. Thanks for bringing it to the top!

Don,
What are you going to use instead of the cogs?
What RPM will they be spinning Vortech. I am interested.

The cogs are still up for grabs. The crank pulley is a 75 tooth and the s/c pulley is a 30 tooth. Impeller speed will be...
50025 @ 5800
51750 @ 6000
53475 @ 6200
56062 @ 6500
(These calculations are fot the V1-V9 s/c units)
I have recently had another set of custom pulleys made by ASP that incorperates a vacuum pump, and utilizes a 50mm cog drive, that is the only reason I am selling this setup. I have almost $1000 into the new setup, and need to ofset the price a little. Thanks, Don B.
