Excellent! Cant wait for numbers!
I am wondering where/how people are figuring out what pulley sizes nets what RPM your at with the blower. My figures tell me a 3.0 with a 9k rpm will make the blower spin to 56,925 RPM. Which is 4k rpm over the posted limit of the 1200.
Are we al to the point of who cares lets just spin the SHXT out of it?! lol

(crank pulley / compressor pulley)*redline*gear ratio = impeller speed
(5.45/3.0)*8000*3.6=52,320
In my case
(5.45/2.8)*8400*3.6=58,860
I didn't want to overspin the blower but when I called for my new pulley a little birdy told me that the companies de-rate the blowers to keep people from overspinning the blowers....I was told the numbers have been said between 10-20% so I was like what the heck give me the 2.8 instead of the 3.0.
I will always be running this pulley as I cant stand changing the pulley.

Talked to them for ~15mins today about belt sizes
Rain- SOS told me 3.6 and Paxton told me 3.45 I just have it saved as 3.6 and forget to correct it.
