<BR>That bike was at the Moto Show in the BMW booth. Really nice in the flesh. I talked tech with builder Stellan Egeland for over a half hour at the show, he's the genuine article. Check out the BIKES link here: http://www.seservice.se/ He claims the "long cold winters" are his source for inspiration. <BR>
Is he using engine oil to cool the turbo and returning it through the oil cap? I was thinking it would be neat if he could put all the turbo stuff in a hot pannier on the left side.
Stellan Egeland is a cool guy very innovative check out his creation The Hulster http://thekneeslider.com/archives/2007/08/08/hulster-8-valve-2007-amd-world-champion/ I'd like to build a turbo for myself but dealing with Big Brother here in Sweden can be very frustrating. I built one for my Harley Road KIng that worked quite well and it would be fun to do it again ,a turbo and some pipes and bends and an angle grinder and a TIG welding unit is all you need
Maybe...couldn't find any pics showing that part of the oil-return plumbing, but it would work. Turbos actually need a pressurized oil supply more for lubrication than cooling, as the hot side/turbine is designed to run at exhaust temp, and the compressor doesn't get very hot in comparison, as long as the heat shield is installed and you follow proper shutdown procedure. Hot shutdowns do very bad things to the bearings. The oil helps with cooling, but loss of the oil feed will lead to a squeaked bearing long before it overheats. Turbo return oil is a mixture/froth/mousse of air and oil, and requires a much larger line that re-enters the cases above the sump's oil level- it's that water-hose sized plumbing that's partly visible just below the compressor outlet hose. Neat, maybe...but all the extra plumbing to get there and then back to the engine would create a LOT of boost lag. As installed, the plumbing's already about as tidy as you could make it.
That sure does look like an oil return line, but on the 1200 it may be the crankcase vent. On the stock 1200 motor the vent hose fitting is molded into the left side cam sprocket cover. The picture is too dark, but Dacar Motorsport may have removed the cam cover vent fitting and hose to make room for their plumbing. <BR>
Don't think that configuration would work too well...two small turbo's relying on a fairly lazy stroke to spin them up...not nice if one boosts slightly higher than the other!
Ron at Bavarian Motorcycle Workshop in Salt Lake City ( http://bavarianmotorcycleworkshop.com/ ) turbocharged his 1150GS. Sounds like a jet taking off. Supposedly has significantly more power.
Video of the test those who did not know the Italian language: It works above 6000 rpm (the engine is limited to originally specifications bmw) maximum power to the wheel 130 hp Kit price 6.000 :huh Mounting costs 700
