looks amazing. will you have it pressure tested before you put fuel in it, where do you get that done at? radiator shop?? i want to build one of these for my gsxr1100 that has room for a ram air underneath including an airbox with ducts from the front of the bike, some day anyway. A ram air would add about 15 to 20 horsepower i am told, and its free boost. without making a recess for it under the tank theres no other way to filter AND duct the air into the carbs without making a custom tank and making a path under said tank.
This is all by hand. Tin Snips and TIG welder. Today I got a bunch more done, but need to post pics. Tomorrow, maybe I'll be finished. I may attempt an in-house pressure test. At least I will fill it with gas and run a torch over the outside...or maybe I'll just do a visual inspection for leaking. Then lay up some hot flecks. Any suggestions on color/color-scheme? I just might go silver, but that is no eye catcher.
Ram air...sorry but I think you'll get more like 3 - 5 HP maybe. I did some heavy reading on it back when I was toying with the idea. It seems to me with every 1 psi increase in intake charge a yield of approximately 5 HP can result. Don't quote me on the last, but I've got a book I can double check those numbers. Ram air is good for those race guys who try to squeeze every last HP. It is a trick thing though. I think it's cool.
the bigger the collection scoop the higher the pressure will be and the smoother the tract of flow too. if you could get as much as a single psi of pressure(70 millibars) into an airbox at 100 mph using smooth ducting and a large scoop, i think the mid range response and torque alone would be worth the hassle. only thirty millibars got this little beauty with 123hp up to 131. my beast has 160 plus horse power to start with and the bigger the engine the bigger the gains from boost will be (that was only a 900, mine is an 1127). i really think a gain of 15 hp would be more reasonable and a stronger bottom end would be apparent too. any help you give the engine to feed air into itself cant hurt.

having a lazer cutter helps i bet :)

i have an interesting article you might find interesting, i was surprized at first. http://www.sportrider.com/tech/146_9508_ram/index.html
