I am curios what the air distribution between the cylinders is like with a screw blower compared to a roots type blower, that way I can get an idea of where to start with my port nozzle jetting. With my old roots blower I was richer on #1 and #2 and gradually go leaner towards #7 and #8. So I'm not sure if a screw blower has the same affect. I am not running dribblers, so i am wondering if anyone can help me get an idea of where to start. Thanks.
