Could my prop be bogging down the motor? I am running a MA14X8 so maybe I am running a too large of diameter prop? I guess I could go with an APC 13X9 or 10 or something, but I was just paranoid that the radial cowl of the 190 would affect the thrust since it is like a big salad bowl behind the prop. Should I just prop this sucker down and get the rpm up? This is where those with the experience and "know how" chime in....

Jake,
I run anAPC 12x 12N on my YS .91FZ. That is what has been powering my P-47 all year, and it has a radial cowl, too. Back in the day when the .91AC was the main motor used for racing, Sweeney, Sullivan, and others, found that it gave the best performance forthe purpose of racing. Jim has always used the APC12 x 12N on his YS.91-powered Fw 190Ds. I recommend giving this prop a shot.
