Default RV-8R second test flight prelim data.

We had a successful and event free test flight number two today!!! Prelim numbers show a cruise speed of 155mph at 23" of mp and 3000 engine rpm. This is 15 mph faster than my initial design goal. This is also only 15 mph slower then my fathers 200hp RV-8. These speeds would not have been possible without the use of the GT electric prop. After shutdown I laser checked the cylinder head temps. None of them were over 200f. The baffling is doing its job quite well! Time to de cowl and do a visual inspection and filter check. Video is posted below.

My only beef with these videos is that it was -12C here this morning and seeing those palm trees and sunshine is annoying

I love the look and sound of that airplane! I'm jealous...

155 MPH, or 155 knots?

Default Radial benefits...

all cylinders should theoretically get equal and instant cooling when airborne if baffling is working properly...they just like to leak a "little oil" in the bottom cylinders...I miss the Wright radials we had on the S2F,Wright R-1820-82WA radial piston engines developing 1,525 horsepower each...

I am not seeing a lot of 200hp RV8's cruising at 3000 rpm and only hitting 170 mph. Just sayin'. The -8 you are comparing to must be a monster dog. Not taking anything away from your radial - that thing looks awesome!
