For anyone interested magnuson said my set-up is currently spinning 17,400 at the rotors so there is still some room. Thinking about running the 15% overdrive with an electric water pump and adjust the snout pulley as needed. Looking fir 12-14 psi

 

What rpm do you shift at. You can calculate it yourself.

 

I had a custom 2.5 pulley made by SmoothFlow pulleys that got me 14psi.

 

I Probally need to do this calculation, I'm sure my 1900 is close to maxed out, but I'd like to know if any is left in it.

 

Divide your crank pulley diameter by your snout pulley diameter then multiply by your highest shift rpm
