Have any of you guys calculated your impeller speed? If so what pulleys are you running and the impeller speed? The link below will give you the calculator to figure it out.
Thanks

Spence, have you ever worn out the bearings or anything overspinning the blower?
393 stroker with YS-trim Vortech :-)
nope,
that blower was on the car for 2 years, made close to 200 passes with it, never had a problem.

Thats great. At how much boost did you decide to go with any type of aftercooler. I still have pics of your one install of the intercooler in the front of the car.

I decided to try inter/aftercooling after a few blown head gaskets thinking the discharge temps where the problem, but they werent. I went air to air first, this worked good, then I went to the igloo, also worked good, now I am going in car cooler, will have results soon. without the coolers, I have seen 27psi at 75-7600, with the coolers usually I see 23-25psi depending on the conditions outside.
