JUST as an FYI, as I do not want to get into another massive magic bean thread..
quite a while ago I had an in depth discussion with Gerry Mallicoat and he reviewed the Vipair concept and compared it to his "race experience" he said that the vipair IF COMBINED with the closure of the NACA duct ie use a black piece of plastic or similar to close so it still looks PRETTY, that the user would see greatly improved ROAD horsepower to the same tune as the increase he saw on teh GTSR race cars (I have a picture of the GTSR airbox up front, it looks alot like a vipair), at the time I pondered creating a spring loaded NACA closure device that would close as the vacuum was starting to be created in the airbox, this way you would still get as much fresh air stop ight to stop light as well as benefit once the car got moving to those "closed course speeds". But, the bottom line is that product develpoment requires lots of investmet in time and $ and then there is the BS of trying to get people to look at the physics vs the BS when it comes to making a buying decision to then compensate one for the trouble. Bottom line is the reward is not there.
BAZ - I made this Carbon Airbox in this thread, it will fit with the ROE, I can help you with how to if you need. I actually gave this airbox to OK after my shipping girl shipped a carbon fiber vipair that he bought to someone else by accident and shipped him a plastic one. The carbon one then ended up on EBAY.
These fit great, especially with a ROE and it will increase HP at speed as the air is venturi fed into the throttle bodies VS the sharp almost 90 degrees of the stock airbox.
