Prm, rath, jetblast, and another guy that i saw post em on ebay. But from experience with the rath scoops(thats what i have) i can only tell you that i think they are sitting on my quad for looks because I havnt noticed a difference really. It seems the fan turns on at about the same amount of time.
Prm has top and bottom fins too, Jetblastgear.com bolt right up and are aluminum, Rath has longer side fins that "protect" the side of radiator, but I think you need to remove the radiator overflow.........
Jetblast has some of the "cooler" (heh heh heh) graphics if you ask me, and I run that set too.........never argue with a Boeing Engineer......
And yeah the fan doesn't come on as much with the fins installed........only pops on after 3-4 back to back comp hill runs up the little 200' tall Oregon dunes.........
Thanks Dave. Rob, along with running Redline's Water Wetter, my fan hardly ever ran at all during a two hour harescramble. I think there were 8-10 Predators, myself and a "sponsored" racer were the only ones with scoops...by the end of the day, they ALL wanted scoops.
How thick is the al you're making these out of? Do they mount in front or behind the rad guard? Mine fit behind with a .6 whole in each to go over the guard mounting hole. Basically clamped on by the rad guard.
I'm just curious what other people have done. I made some this past weekend while visiting family in S. Fl. I made them out of some scrap 6160 T-6 that mother bother uses to make grill doors. It worked out well because he cuts the exact same amount off each door as the rad hight. The scap has a slight curve to it that looks pretty good. I'm all about sparkly bits and all, but I opted to bead balst them for a mat finish. They match the frame and rad well that way. I'll post a pic or two tonight.
I'm not looking for info to sell my own or anything. Just curious how others are made.
The T-6 you bent your's out of is already very hard and subject to cracking when worked with. I use 2024 T-3 aviation grade, cut, drilled and worked according to approved aviation standards. You have to be careful not to induce "stress riser" points, otherwise the structure won't last. I've only had one fail, and that was smashed when a quad was spun and hit a log. I never promised they'd hold up to that... I gave him a new one anyway.
Great....thanks for the info modquad....I was opting for the free sheets that I had to work w/. I've used it for pipe brackets on sportbikes w/ no issues. I bent it w/ break and didn't need to bend it far w/ the gentle curve it already had. However, if I have an issue I think I'll take your advise and use the t-3.
