Cowling differences ?
Hi! I'm new to the site, but have admired Van's designs,(and the people who build them) for many years. I'm finally at the point to begin looking to acquire an RV8.
I've noticed that some aircraft have an air scoop on the bottom of the cowling, while others do not. At first, I thought this was a function of whether the engine was carbureted or injected, that the carbed engine would have the scoop, and injected would not.
But I have seen injected RV8's with the bottom scoop too.
I prefer the sleeker look of the "scoopless" cowl, and had the following questions.
1. What factors determine the necessity of the lower scoop?
2. Can a scooped cowl setup be converted to the non-scooped arrangement?
(Depends on the answers to #1, I would presume)
