At the end of my mini oil temp test post I had just received in the mail a cooling shroud/scoop handmade by ce. I took some pictures and I'll post a few of them today. Tomorrow I'll try to start a few test runs with my high tech thermometer. Here's a direct link to the Photobucket album for your perusal. More pictures will be added as I do the testing. Rich

Does that go over the Flywheel Fan? If so why is the Inlet BENT TOWARD the Front and NOT Straight Across like the OEMs? Is it so it gets more air directed into the fan?.

Yeah, it is oriented up and forward to scoop air when moving but not catch rocks or debris, and not suck in hot air off the exhaust pipe while idling.
There is plenty of room for further modification with a razor knife to allow a greater rake to the scoop, and even open it up some more. Depending on the scooter, the outer edge of the scoop is beyond the fairing about an inch.
Just be careful with that axe, Eugene.

You did a FANTASTIC Job on that Air Scoop to pull in air under the Shroud CE!! Looks really nice.

I got ce's (well.....mine now!) air scoop mounted on my wife's Silver Streak Peace 150 cc. It only took about 10 minutes and popped right into place. I won't be able to do an oil temperature comparison until the weather approximates conditions when I ran the mini oil temp test; that was about 85 degrees. Since winter seems to have returned to the deep South I'll have to table any tests for now.
One thing I didn't realized until I was installing ce's creation is how close the exhaust pipe is to the OEM shroud intake. The scoop does a nice job of getting the shroud off of the muffler. I'm not sure how much it will help at speed but at the very least it's gotta help at a stop light.
ce did a great job constructing this and after putting it on I think it's a heck of an idea. When the weather gets right we'll see how much of a difference it makes. I'm leaving it on regardless....it looks cool.

Thanks for the pics. Great Job! I was sitting here wondering because on another site a fellow had made something like this and was put down that it would never work, his got the scoop a little further out and was designed to ram air into it from normal driving.but then this is a site with open minds. I have to keep in mind that some sites are strange. I was taken to task on another site abrevuation for Bobby Smith. Regardless this has restored my faith in air scoops.

hi 89newbie main stream conscious still that it is an intuitive illusion that it will for example= blow a slow speed fan on a hi speed and watch the hi speed slow down. So what you are saying is when in the air stream if scoop captures too much air flw it will actually slow the engine fan thus resultant would be increased temp instead of decreased. |

Simple physics suggests that the scoop moving through the air will create a vacuum at the fan...
It is like blowing across a Coke bottle...
However, I think if a piece of aluminum dryer vent was added and
run under the scooter...facing directly forward, then you could increase the air pressure at the fan when the scooter was moving and improve cooling

Whether a scoop gets more air in or not, increases cooling capacity or no, despite whatever speed the fan might be turning remains up for debate... However simple physics suggests blowing across the rim of a Coke bottle is far more akin to the fan grill opening moving forward through still air without any scoop, not with one: air is moving across the opening, not directed into it. |

There needs to be a test...to set this to rest

Damn it, Jim, I'm a Doctor, not an aerodynamics engineer!

Bashan is going to do the testing with Ce's Scoop.

>>>"how can more air go through a smaller hole?"
Higher pressure... ?

WOW!! It amazes me that someone has worked in so many fields in the industry and gardened all this knowledge. Maybe the Jets and stuff which have the Air Intakes facing forward have it all wrong, HMMMMMMM food for thought don't you think.
Jr,
Try and be a little more positive will you, we don't tell you your full of it with some of your stuff that we know is all b.s we just go along for the ride.
