Does anyone know how to figure how fast I'm spinning my t trim. I have a 74 lower and a 31 upper. I know that the t trim is rated at 55,000 and I was told that these two pulleys would be okay. I just want someone who knows how to figure clue me in on how to come up with how fast it is spinning. The rpm in which I am shifting is 6800-7000 with a powerglide. Thanks for all your help....

Go to http://www.vortechsuperchargers.com/...pspeedv-1.html and plug in your cogs instead of inches in the pulley diameter spaces and it will calculate it. FYI, with your pulleys, you are spinning it 56001 RPM @ 6800 and 57648 @ 7000.
