The M&W gear setup was orig. for a jet or I/O and I tried to run it on a v-drive. Had great low/midrange power but was all through at about 5800 and I wanted more. Could have played around with exhaust housings but the blow-thru had its boost limits [9-10 lbs] I ran a Holley 850 C.S. carb on a Offy manifold. It was my first experence with a turboed gasoline engine as I had alot of experence with turboed diesel engines. I now run a Gale Banks setup with a single element intercooler on a 460 BBF, same boat. That setup is alot more compatable with what I want. It makes app. 14 lbs boost and allows the engine to spin over 7200 rpm. The M&W Gear is a good assembly if you don't try to make it do what it wasn't designed for like I did.
