How much boost with 9.1 CR
I'm building the engine now and what to supercharge next year.I am trying to find the right pistons for my engine without spending a fortune. I also want some power now before I supercharge.All the pistons I find have too high or way low CR.My heads are aluminum with 58cc chambers.Also how much boost can I use with the stock crank(magged and reground)?Is there a way to decrease CR with a gasket(how much)?The rest of my engine appears in sig.Plus maybe Scat rods.
