What a surprise it was to find that my certified H2AD (1200 since major, with log books), would result in a 2 to 4 inch bump on the cowling, require minor modifications to the baffles, special engine mounts, (comes at no extra charge with finishing kit), and a modified exhaust system. I did not like that! Now, I am going to sell this engine, and buy a new one. I have checked with Van's and Vetterman's, they said the engine mount, and exhaust system will fit their new D1A. This is a good thing for me. The message to the group is to think ahead and decide if you can live with these types of modifications. A lot of builders willingly trade the bump on the cowling in order to save thousands of dollars. Nice thing about the RV is you can change your mind.

He removed the engine driven fuel pump and went with 2 electric fuel pumps and does not have the cowl bumps.

I took these yesterday while flying off my 40 hours. The conditions are as follows. RV-9A, O-320 D1A, Hartzell prop, empty weight 1080 3/4 fuel + 210 lbs pilot + 20 pounds of god knows what else = 1472 lbs Main gear pants and fairings installed, nose wheel and leg still bare (to lazy to finish it) At each altitude I paused long enough for the airplane to accelerate and stablized then leaned to ~ 50 deg ROP. 8500 msl 8340 DA 2 deg.

I for one appreciate you taking the time to post these.
