Just finished my RV8 after 14 years. I have a IO360 A1B6 with single mag and light speed ignition. Engine has 1500 hours on it. I am a aircraft engineer and went to painfull lengths to build it fast.ie no gaps at control horns/well fitted fairiings /clean lines / angles of incidence and rigging done with laser levels. Flys straight, trims in middle. My speeds are low. 5000 ft standard day25 inchs/2500 RPM 165 Knots /23 inches/2300 RPM 152 Knots/full power 171 Knots. I can blame full power speed on tired engine but at 25/2500 I am setting the power so the speed is airframe limited. My prop is a new hartzell constant speed with blended airfoil. Built a little heavy due to Christan inverted oil and large mountaint high oxy.530 KG basic wieght. Can anyone advise. Cant find any threads on it
