912is Sport Cold Air Intake

[Jcard]

Did the lift strut fairings, covered the gear legs with leading and trailing edges, fairings on the shockmonster shocks.
Went from 90 to 105 cruise, less map and 7 gallons per hour to 6

What engine are you running that was burning 7gph? got any pics of the fairings for the shockmonster?

Do you have an air filter?

[rocketman2tm]

Yes, the stock rotax 912is sport air filter is located in the side NACA intake. I believe the 915 has the filter located in the side NACA as well.

What kind of climb performance are you seeing with your 912iS? about to pull the trigger on this engine but I read recently that if you are close to gross weight climb performance is about 300pfm...if that.

I'm not sure that I've ever seen it quite that low. 500 fpm is probably the lowest I've seen it at gross on a hot day. Keep in mind though that there are not a lot of mountains in southeast Wisconsin where I fly.

On a cold day when I'm by myself, I've seen well over 1600 fpm.

Thanks! This is what I was hoping to hear!

Couple pictures. rotax 912ULS with aftermarket fuel injection and turbo.

Wow, those shockmonster fairings are beautiful! What wing do you have?

I'm curious if the intake box has holes in the bottom to release the increased air pressure (if there were none) from constantly having the rammed in there from the naca duct. If there is increased pressure wouldn't that be akin to flying with higher air density than the altitude you are at and possibly improving performance?
