WebAug 31, 2024 · Roots superchargers are "external compression" blowers because the air compression takes place outside of the supercharger. Roots type superchargers first … WebNov 10, 2024 · We’ll assume you are running a 4.030-inch bore. Static compression ratio is affected by multiple variables including crankshaft stroke, piston-to-head clearance, head gasket thickness, and piston valve reliefs (if present) or the presence of a dish or dome in the piston. Here’s an example of a 350 with a 10.1:1 compression ratio:

WebApr 10, 2007 · Sure, just like for N.A. motors there are rules of thumb. Something like: Use 8:1 to 9:1 static compression for low boost non-computer controlled carbureted blower motors. But that doesn't take cam timing into account. Surely cam timing has just as big an affect on optimal static compression ratio on blower motors. WebJul 14, 2009 · Like stated before some of the top modular cars are running compression ratios in the ~11.xx range on twin turbo race car. Let us not forget also back to one of my points that a high C/R isn't a garauntee, A 4.6 3v with the FRPP blower is rated at 550hp on 10-11# 10"1C/R the 5.4 4v is 540hp at 8.5-9. graphic service company
