94BansheeRider Posted April 14, 2004 Report Share Posted April 14, 2004 A while back I had thought of putting shrouds on either side of the fuel tank to funnel air into the air box. The thought was: The faster you go, the more air pressure inside the air box. Has anyone tried this before? I think it would be cool if it works Quote Link to comment Share on other sites More sharing options...
nater006 Posted April 14, 2004 Report Share Posted April 14, 2004 you'd want to seal everything really well. I got a pressurized ram air kit on my 900RR. It uses foam donuts and a foam seal to keep it all nice and sealed. Otherwise it'll never pressurize or make a difference... You can get a cheap roll of the stuff that you put between the topper and bed on a pickup (sticky foam roll) that works the same. Quote Link to comment Share on other sites More sharing options...
Wallrat Posted April 14, 2004 Report Share Posted April 14, 2004 I think the gains would be minimal due to the 2stroke design (no valves to keep the pressure in). I know of people doing this in the 2stroke R/C world and pretty much the outcome was a slight increase in power and a HUGE decrease in reliability. You'd have to jet really fat so that you wouldn't run lean when you got up to speed. Apparently it makes the engine a bear to start and keep running.

sandman121383 Posted April 14, 2004 Report Share Posted April 14, 2004 nice avatar wallrat! uron? or however u spell it Quote Link to comment Share on other sites More sharing options...
blazenlo Posted April 14, 2004 Report Share Posted April 14, 2004 I would think that that would cause your jetting to be off also. Because your always getting a different amount of air. Quote Link to comment Share on other sites More sharing options...
MotulMonsta Posted April 14, 2004 Report Share Posted April 14, 2004 Unless your always running fast and tapped out in 6th gear, I don't think it'll be worth the effort. Besides, you gain big ponies when you simply take the airbox lid off. Quote Link to comment Share on other sites More sharing options...
frocashmoney24 Posted April 15, 2004 Report Share Posted April 15, 2004 if ur really into get a universal cold air intake ofr a car and slap it off ur carb Quote Link to comment Share on other sites More sharing options...
FORMULASPEED Posted April 15, 2004 Report Share Posted April 15, 2004 My buddys 250r has somthing like a ram air set up. It came stock like that. If you were to do this I think it would be better with a car amp fan. By installing longer hoses between the carbs and air box with a fan in each tube, making it revs with the bike. I dont now if it would work though. Quote Link to comment Share on other sites More sharing options...
Wallrat Posted April 15, 2004 Report Share Posted April 15, 2004 Yup, Auron. Good obs Quote Link to comment Share on other sites More sharing options...
MotulMonsta Posted April 16, 2004 Report Share Posted April 16, 2004 Those fans won't be able to move enough air and they would actully impede airflow. You might as well get a turbo kit..that's a proven power increase..shit load of power. Banshee sucks HUGE gobs of air at higher rpms..I'm talkin a shit load of air.

Wallrat Posted April 16, 2004 Report Share Posted April 16, 2004 That whole fan thing is a joke. What kinda boost does your typical turbo put out? 10? 15psi? Those fans would be lucky to push 0.2 psi. Quote Link to comment Share on other sites More sharing options...
banshee tuner Posted April 16, 2004 Report Share Posted April 16, 2004 Yea that's like that tornado fan that is supposed to give you better gas mileage and would probably restrict air flow. Just think someone got rich off that junk. Quote Link to comment Share on other sites More sharing options...
snowprophet1 Posted April 16, 2004 Report Share Posted April 16, 2004 If you ever were going to experiment by making a ram-air setup, you would want to make sure you take your carb vent hoses, and plumb them into your airbox. This would make the pressure in the float bowls go up as the air pressure goes up. BUT, if your carbs are not tied in originally, your jetting would be off (probably too lean) if you don't jet up. Example: Polaris snowmobile...carbs tied into the airbox=difference in underhood air pressure has less effect on performance at changing speeds. Yamaha snowmobiles...carbs vented underhood (not to airbox) the underhood pressure does effect it's performance slightly, but jetted safe from factory so as not to have warranty issues. ATVs don't have hoods like snowmobiles covering their motors, but still would be more consistant if the carb venting was tied into the airbox.

yama-dude Posted April 17, 2004 Report Share Posted April 17, 2004 There is no such thing as RAM AIR. The only way to pressurize an intake track is by means of a turbo or supercharger. The phase "ram air" was coined by the automotive industry in the 60s. It would more accurately be desribed as cold air induction. There is a huge benifit to using air 70 degrees cooler than the air under the hood of a car. The advantage is from the drop in temp. no ramming is going on.

slowpokebanshee Posted April 23, 2004 Report Share Posted April 23, 2004 I used to ride a GSXR 750 (before being hit by a car) and it had "RAM-AIR" but I remember reading a test report in cycle world or one of the other magazines, about ram air, compared on the four big bikes (honda, Yamaha, etc.) and none of them created anymore HP until well into triple digits.....which is good for super bikes, but not banshees, I agree with an earlier post, you will see more benefit from ditching your air box lid, or going to a turbo.....bigger carbs, pipes, boost bottle (ha-ha) porting etc.....
