Ethanol in a VW motor

[1500SBR]

VWDMC,

Yeah it is a tricky header, one which I haven't seen made as an actual kit. Here we have a lot of custom exhaust shops and the one I use has developed this system where the turbo sits right above the left axle. There is a little bit of cutting and fitting. To make space for the turbo in that location. I mentioned it is a nicer location because it does keep the heat out of the bay.

I included a few pictures so you guys have an idea.

Picture of the trick manifold.....

Let me know what you guys think...

Take care

you guys don't have any issues with the #3 exhaust pipe being so short and all unequal? and where does the external oil cooler go, 'cause usually us americans put it where that turbo is

[1500SBR]

No issue with the short 3rd cylinder (it is all under pressure anyhow). It does create some difference while you are off boost (theoretically - but unoticeable on lesser than extreme performance applications). If you still feel this is something you would like to fix. You can always re-route the 3rd cylinder tube.

The oil cooler will still fit next to the trasmission (I don't know wxactly how you guys mount it, but there is enough room for a 72 pass) or you can move it to the other side of the car. The header can also be made to mount the turbo on the right side.

Also, I haven't seen one, but I've taken measured and I'm sure you can make it fit. You run the oil cooler on one side and the charge cooler on the other side....

But you didn't tell me what you thought about the headers and all. Cool, not cool, crappy....I think this way to position the turbo is awesome, no comparison to the other methods...

I like the idea of the turbo over the gearbox, however I was planning to mount mine behind the rear apron (behind the motor, under the tinware). I have seen a few VW's with this set-up and cant imagine the oil return should be too much of a problem, especially since its so close to the where the case is full flowed that the pressure should be there to stop the oil pooling. Be interested to hear if anyone has had experience mounting the turbo in the position.

yeah i like the mounting, it's cool, but accessing it could be a little harder than a turbo undre the apron, but i guess you would'nt need to do much maintance on it, although i don't mind crawling under the car

So i looked up how hard it would be to get/make 180-190 proof fuel, and it would take a $400-500 still and alot of work to constanley make enough fuel, not to mention getting a permit and all that. sso what kinda power do you see possible woth E85 vs. pure alcohol, becuase that would be much easier to get although not cheaper in the long run.

Cam, I don't think you can fit the turbo under the rear tin, without removing it. If the turbo sits too low, you will need a scavenging tank for the oil return line (which has no pressure) and a scavenging pump. For the gravity to take care of the return line, the lowest part turbo has to be mounted above the oil level inside the pump otherwise it smokes under certain situations if not all the time.

VWDMC, I can't give you exact figures since we do not have E85, but from mixing regular Gas and Alcohol, which some people do, the results will probably be the same in terms of power. Less forgiving when it comes to ignition timing and a bit hotter, but nothing too significant. I wasn't suggesting you guys went after pure alcohol of methanol for this use. I was suggesting the use of E85 to begin with. I think it will probably even work better than Brazilian Hidrated alcohol, since water doesn't burn, it simply takes space in the combustion chamber. Gas on the other hand burns hotter than alcohol so a bit combined with alcohol must make a pretty good fuel. Without the hard start and with slight less specific consumption.
