I cant find hardly any info on figuring out what size turbo to run-vs-engine size.I have one from a GPZ750 and most guys say its too big for a single our size.Kinda frustrating since its a big job to plumb one just to find out it doesnt work.

go look up how to read compressor maps for turbos. then calculate what kind of air we need for the dales and find a turbo that may work. all the info is available on the net. if i can find it in my favorites ill post a link.

basic info
http://www.not2fast.com/turbo/glossary/turbo_calc.shtml
a calculator
http://www.turbobygarrett.com/turbobygarre...ech_center.html
lots of info

there are some links that may help out.

by using that calculator you should be able to figure out ALOT. and on garrets site they have some pretty small turbos. one is only good for about 50-130 HP (.4l-1.2l), and thats the smallest one they have so it may be in the correct range. the way to find out would be to look at the compressor map and what kind of air you will be needing. i have a basic knowledge, and dont really know how to do any of this "correctly" lol.

What size is the turbo off of an old Seca 650? I would guess it's smaller than the GPZ unit.

Funny you say plumbing, It makes me think about the oil pressure the C-Dales put out. I am not an expert on this by any means, but I think the oil takes a beetting when it gose thru the turbo and a fair amout is needed to help cool the bearings. I don't think the dale has much to spare.

Yes I think this might be a issue also.They want 40psi for the turbos which use a bushing.The ones that use a bearing would be okay but those are all bigger turbos.Might have to make a tank and pump.Not looking feasible

I don't believe that's quite true. I believe the pressure is low but the volume is high. Try pulling the oil line off the scavenge pump going from the the bottom of the motor near the oil drain plug to the frame. You will lose all your oil in a few moments on a running motor. Wistech had a pic of one of his with a clear glass filter housing so you could see the flow.

Yes plenty of volume but with a bushing type bearing they need pressure.Way more than we have.
