Any online impeller speed calculators?

My 112 maggie currently has a 3" pulley on it, and I'd like to compare impeller speed differences if I swap different size blower pulleys or crankshaft pulley sizes. I keep hearing about online calculators... but hell if I can't find them.
Also, I think our kits come with .85|1 rear pulley ratio (not 1|1 like some others)... is that right?

Ah, finally found one:
http://www.forcefedperformance.com/T...lowerSpeed.asp
3" pulley + stock 7.25" crank = 13,038 RPM <-- my current setup
2.8" pulley + stock 7.25" crank = 13969 RPM <-- s/c pulley swap
3" pulley + 8" overdrive crank = 14387 RPM <-- oversized crank pulley swap
2.8" pulley + 8" overdrive crank =15414 <-- both s/c and crank pulley swap
Looks like I'll get a little more out of a crank pulley swap... too bad they cost so much more.
