My plan was to go with the Silver Hawk injector, mostly because that is what everyone offered if FI. Reason for going FI was here in the UK carb ice is frequent and I presume the injected engine is smoother and more frugal on fuel. However the things stacking up the other way are: - I really prefer the look of the O-320 cowl - the air inlet is presumably matched to the engine - VANS can supply the brackets for the carb but not FI and the O-320 FAB will fit - there are not so many aircraft to copy how things are done near me. I have built a carb -9A before and feel more confident. - there was also an interesting old post at Vans Airforce "Carb vs Fuel Injection" by Stein Bruch which go me thinking that perhaps the money is better in my pocket. Feel free to tell me I am making a mistake if you feel strongly. If I go back to a carb I guess I have to understand if I want a Marvel or someting else. Is there any other carb I should consider? If so what does it offer? Cheers, Steve. ----- Original Message ----- From: "rob ray" Sent: Wednesday, January 25, 2006 1:38 PM Subject: RV4-List: Re: RV4-List Digest: 1 Msgs - 01/24/06 > --> RV4-List message posted by: rob ray > > Steve, I didn't use the FAB on my RV4 as I built my own tunnel ram > equipped with Ram air for normal flight and a K&N filter by-pass for > ground operations.
