    A few years ago. (about 6) A bloke from Colac had this set up..  But i dont remember his name and so dont know if he is still part of this group .  I would like to ask him for advise or if anyone else has gone this road.     Son bought complete setup just a couple of weeks old from 06 softail and we aim to fit to 2000 softail.  Yes 06 injected /2000 carby. Dont think we have to mod pipes yet but guess all will be revealed when it arrives

    Are you sure you mean Draw Through vs. Blow Through?  99% of turbos nowadays are blow through ie the turbo sucks in air and 'blows' the high pressure air through the carbby/throttle body while a Draw through has the carbby/throttle body as the first item and the turbo 'pulls/draws' the air fuel mix through the turbo and into the engine (draw through turbos MUST have special internal seals to stop the fuel from buggering the unit)
    Yell out if you need any help as I'm very familiar with turbo Harleys (my web site is http://www.turboharley.com.au/)

    Sweet....What unit is it?  I'm Aerocharger.
    5 - 8lbs is a good range for boost.  I have run at 20lbs for about 3 kms and that was just plain freaky!

    Tussuck, just as a matter of curioisity, Ive seen a few guys running around with turbos that look like they've come off cars. I'd make the assumption that something in a similar CC range could be apapted to run on a V Twin....but you know what they say about assumptions! Keen to hear you opinions mate.

    Hi,
    Yes your right about the key thing being CC rating of the host car (bugger all use installing a 5L V8 turbo on a harley as it would NEVER spin up until your red lining).  Having said that its important to note that the entire car 'package' will have been developed with the turbo in mind so you have things like cam, ignition system and compression playing important roles in the car side of things.  

    Once you get to the turbo they are either oil cooled or water cooled so you need the oil cooled for the harley (there is only one oil feed and it both lubes and cools).  Important is the size of the housings which determine how the turbo makes boost - you need to be able to understand and read a compressor map plus know what air flow the engine makes etc.  Its not complicated, but you do need to understand the principles etc.

    Before I went with the Aerocharger unit I had worked out what cars run what brand and spec turbo so knew what to look for when i went out shopping.  Oddly enough the right size for my harley was quite a small unit (it was off a tractor of all things, BUT several Jappa cars have unit very close to whats needed - the thing is they are tend to be water cooled)

    My turbo is oil cooled with an internal oiling system so no external feed needed.  I also had ceramic bearings installed so they handle the heat better and have less resistance.
