The worst news is probably climb performance.  The best I can manage now is 1500 fpm, which is still at only 100 mph.  I'm hoping the wheel pants and fairings will improve this, and put it back in the 120 mph range where you would expect it to be.  Either way, it's unlikely that I'll ever make it back to 2700 fpm like it was with the turbo.  It does appear that the turbo was pulling it's own weight, but I'm still happy to be rid of it.   This is another area where the prop pitch baffles me.  You would think that reducing pitch, and increasing rpm would help climb, but that just isn't the case.  At 13 degrees, the best climb was 1000 fpm, at 5400 rpm, and 100 mph.  At 15 degrees, best climb is 1500 fpm, at 5100 rpm, and 100 mph.   I just do NOT understand this, but it also happened back with the turbo.  Is it possible that this is just something goofy about the Warp Drive prop?  I want to run the engine at higher rpms, but neither speed, nor climb improves.  Am I losing all the extra power on the prop?
