Here is my ?
I know that the max impeller speed for a Novi is 55,000 rpm. I also know that Iit is caplable of 27 psi. It is pullied for 8psi of boost from the factory. If someone is to change to a smaller head unit pulley this will also increase the psi. To obtain higher boost levels, Must the head unit be sent back to Paxton to be "tuned" or what. Once it is " tuned" what is the max impeller speed? Once it is "tuned" I know that the internal parts are different, but what parts? And does anyone know how much it cost to "tune" one for higher psi. I''m in the process of converting to the 2000. I really want to run 12-15 psi of boost, if I pulley the factory "non-tuned" head unit will it last? or should I go a head and have it "tuned"?
Thanks, Rusty
