First off thanks to everyone for all the help on my new setup. Since I bought the car with a sn92 already installed and no paper work at all for the mods and since I have no experience with SC systems this board has been the greatest tool possible. Anyway I did the math and with the 6" crank pulley and 3 1/4" SC pulley it should be spinning around 46- 47k at the 5600rpm shift point. I was told it was rebuilt but have no paper work proving it. Would Paxton keep records for kits sold if I give them the serial #? Also from what I understand 37k is the absolut max for the sn92 is that true? Thanks again, any info is much appreciated.

I don't think they would have info your looking for.

This is a chart I have that will give you good info on sc speeds etc.

I did the math that put me at the SC rpm I came up with... CP/SCPx4.4x RPM at shift point. Ive heard if the sn series is rebuilt it can take more rpms.
