I had told a couple of people that I was going to add scoops to the side of our RTS and would post the results. The scoops that were made were temperary, and more like a deflector than the actuall ones that I am going to permently attatch to the bus. I was worried about wasting a bunch of time building the stainless units and then finding out that they didn't work , so I picked up a piece of scrap that I had and made a temperary scoop to go on the side to try it. It was only 2/3 as tall as the opeing of the rad inlet and open ended, 6inches of sheet metal bent into a C shape, and I stopped at a rest area in the mountains were the engine temp would get up to 210 at the top pulling on the floor in second gear at 50 mph, and put them on( it was split into two peices so I could still open the rad door). Well it dropped the temp down about 5 degrees at the crest, but what I found it did was help it cool down while you were going down the other side, when you were getting close to the bottom of the hill you were at least 8-10 degrees cooler at the bottom. I will make the new ones now to bolt on where I have these now, I am sure its worth it. On the flat level ground it keeps it a little cooler also, it stays right at 180 now instead of 188-190 in the 99 degree heat at 70mph. 35FT RTS 350 hp 6V92TA I am sure differant buses will produce differant relsults, IE: rad placement ,highth, etc. Have fun.

Could you elaborate on how you positioned them on the grill ( inside or out or ??)... I think I have the same problem. I need to get the air into the radiator as much as possible. Did you take off the upper block-off sheet on the pass side of the side door to let more air out? Maybe a reversed scoop set for that side?

I put them at the back of the door on the left side, on the outside of the door starting at the top down 2/3's the way, bottom 1/3 of opeing had no scoop, and the right side is open. I am building a scoop for the left, and a reverse one on the right. When I had the V8 in ours it never ran hot. But with the 6-92 and 350 hp I think I ran out of radiator. |

A friend of mine said they used to take a 3" dia plastic pvc and put a piece of aluminum to create an air ramp in front of the vertical mounted tube and it would create a vacuum behind it in front of the air intake for the radiator besides what you're talking about at the rear of the grill, in Mexico they have sometimes 2 scoops on them one in the middle also very good idea everything helps |

Steve, Gene Rochester put streamers on a scoop attach point at the radiator on his Eagle and drove it down the road. To his surprise the streamers stood straight out because of negative pressure, thus making the scoops useless. You might check yours and post the results. It may be a quirk of an Eagle.

Well I don't have to check my post, or the results as I know what they are, and have them recorded in the vacation log that I keep, its just the facts. Like I said, " I am sure differant buses will produce differant relsults, IE: rad placement ,highth, etc." STeve |
