With the new head/cam, I am hoping/expecting, about 300 bhp. About the limit of the
M 45 supercharger. Its currently 218whp/183 wtq.
I have a 17% reduced charger pulley. The next step will be larger supercharger or turbo.
Would like to be 350 bhp + I believe in the "Do it once", school of thought.
I want the system to be able to complement my future upgrades.
