I got the showplanes cowl when I bought the fastback kit. Can the 390 fit ok with that cowl? Any hiccups?

Default N299AD
I have an Rv8 with the IO390EX up front ... extended cowl ... extended Hartzell hub (2" i believe) ... 190 knts ....

Smoothest 4 cylinder I've sat behind ! ....

If I built a new RV8 project I would not consider any other powerplant ... love it!

Hi Daniel, good to see “Kermit” is still in good flying condition.

Of all my builds, this ship came out the best with, as you point out, an excellent cruise performance of 190kts.

That's a beautiful airplane! I'll bet you could go 191 kts if you remove and stow the tie down rings.
