Did you plug that big old hole in your intercooler yet? BTW I forgot to ask and I assume the awns is yes, but are you running water to the turbo? I'm also shopping for a new prop. Thinking about a warp drive ground adjustable. Anyone have any experience (I already read what I could find on the RV list) Dave Leonard G'day Mick > I must say you did a good job on the turbine or what was left anyway!!!. Thank you, thank you. I try hard to please. :) Thanks for the update. It's a little scary dealing with a company so far away, but Max seems like a straight up guy so I never really had any doubt he'd come through. Just took a little longer than I'd hoped. 400HP. Yes. he mentioned that. A bit lower at my max rpm of 6300, but still - plenty of grunt. :) > From what he explained to me was that you will get more boost for a slower turbine rpm, I thought it was less boost for the same airflow. > He did mention something about throwing in a couple of peacock feathers just incase you blow it again. Oh! Nice touch. > Now im thinking of changing prop size. ( currently ivo 70" variable high pitch 3 blade ) can you make any suggestions. Well mines a wood 68 three blade with 314 blade area from Performance. It'll accelerate the plane to take off in 1000 - 1500 feet at 4300 rpm and climb quickly at 5000. It'll even climb at 2300 rpm. Should be ideal for about 280 hp in cruise and should get me a better top speed than a variable pitch. Given that you need 2000ft to land I'm not sure a variable pitch prop will buy you anything on a Cozy, and it'll probably cost you at the top end. Are you building a Cozy or an RV? I forget.
