I am using the 200hp Lycoming IO360 A1B6 in conjunction with the Whirlwind 200RV prop. The first -8 cowl was received 6 months ago and we've just begun the installation. The cowl will not work without a prop extension without extensive fiberglass work. Will James directed me to a company called Sabre Manufacturing that machines a very beautiful prop extension. In speaking with the owner, he assures me that there will be no prop restrictions with the use of this extension and that they have never had a problem with this. I have heard that the heavier Hartzell CS prop could have some restriction with an extension. You should check with Sabre Mfg for their input. The original cowling would not fit the engine and Will James is in the process of redesigning the cowling to fit the RV-8 with the 200hp lyc. He has changed the design, including materials used, to create a lighter and stronger cowling than previously offered. The plenum with baffling has been installed and looks great. At this point I can't answer any of the questions regarding increased speed etc. I chose the SJ products because I like the appearance and wanted something a little different. Hopefully, there will be some speed and/or economy benefits. It will be difficult to quantify without apple to apple comparisons which are hard to come by with all the different ways the RVs are built.

Recall the cracking issues around the lightening holes in the Lyc crank prop flanges when those cranks were used in hard acro. A prop extension will only make that tendency worse. While I'm sure nobody is actually going to do hard acro in an RV, a heavy CS prop on the end of an extension might cause cracking over time with 'light' acro, whatever that is.
