All,
Just wanted to give you some feedback on the Rod Bower http://www.ramairforhomebuilts.com/contactus.htm. I contacted him and told him I was interested on fitting his system on my RV-4 (narrow deck IO-320). He said we could give it a try. I drove 3.5 hours to Visalia, CA to see him. I took my FM-100 fuel meter, my lower SJ cowling and my Superior cold air sump. I met Rod and a couple of his buds (good guys). We started looking at possibilities for the installation. Some of the existing parts he had would not work with my fuel meter. After unsuccessfully trying to find an air filter that would work without mods he decided the best thing to do would be to make an adapter. The adapter fits the current filter then reduces the ID to fit the fuel servo. We cut the cowling then he gave me 2 different units so I could play with them at home. BTW he did not take a dime. Then I drove 3.5 hours back home.
Yesterday, the adaptor showed up (he had to fabricate it). I fitted the system in about 4 hours (still have lots of glass work on the cowl). The only thing that did not go as plan was the bracket that holds the alternator. It was just a bit too long and kept the induction system from fitting nicely in its location. I called Rod and told him about it. He told me the same thing happen with his RV-8. So I carefully filled the alternator bracket. Here are some pics of the current installation. The system in these pictures is missing a couple of parts. I am really excited about this mod. I hope between the cold air sump and this induction system, I get better performance. I am trying to figure out how far forward to mount the intake ring. I think if I move it flush with the front of the cowling, I will get better MP. Figure that out later.
