I vote for FI
Today, I mean TODAY...When you look at the real price difference of AFP fuel injection and a carb installation, you will see that the gap has narrowed quite a bit. A NEW carb is nearly 2 grand now!! Yikes..Yes, there is the fuel pump that fits in the mix, as well as a couple of extra hoses, and a bit more work for installation in the RV, but that price delta has indeed shrunk a lot these last couple of years. Fuel is also more expensive, and I suspect will rise in price even further. That makes the meager fuel savings that the FI system can offer an issue worth considering. Not to mention the SNORKLE!!!!Using AFP will allow you to eliminate the intake bulge from the cowl, (10 Knots?) and draw air from the lower cooling ramp. LOP operation is now possible, Maintenance is in reality, no issue, a touch more horsepower, and no carb ice. The downside is learning the hot start trick.
Absolutely nothing wrong with a carb or Ellison installation, but I tell you, I've built my last carbureted airplane.....
