Ducati V-One – Twin to Supercharged Single Conversion

Ducati V-One - Supercharged single conversion

Some guys come up with really interesting engine modifications and Bart Crauwels is one of those guys. Bart is currently working on a project that converts a Ducati 1000 DS, a 2 valve air cooled twin, into a supercharged single, using the rear cylinder as the blower. The 498cc single has 15 HP more than the original twin putting out 102 HP at the rear wheel, torque is increased and it runs fine to 10,000 rpm, 2500 rpm over stock. It's about 30 HP more than the well known Ducati Supermono. The Ducati V-One, as he calls it, is for racetrack use only and when things get sorted out he plans to build 40 of them for customers.

In recent years there have been some custom builders, Roger Goldammer comes to mind, who have replaced the rear cylinder on a V-Twin with a supercharger. Since the cylinder is already an air pump, Bart just used what was already there. Of course, the first question before doing this is whether the blown single will have more power than the twin it's derived from and the answer, in this case, is yes.

Another cool feature is the air tank under the seat, limited to 40 bars, which is good for a 10 second burst of compressed air when acceleration begins after which the blower's output kicks in. On deceleration, the tank is recharged. It's hard to see everything that Bart has done by looking at the photos, I notice an intercooler in the plumbing, too, but overall, I like this a lot.

Big thanks to Hugo for the tip!

Makes me wish I had the sweet Bridgeport mill that the old man used to own. It was only a two-axis CNC, but it was sweet!
 
hey you cant get mad becuase hes a dork and reposted... hes a ginger that, like, you know, makes it okay :p
 
just a thought... how well does CF "tube" hold up to the engine vibrations and heat?

thats something that i haven't seen much of and I assume there is another reason besides cost.

I know some F1 cars use CF intakes.. but I also know that alot of what they run is only good for a single race :p

Yes, it has been done. Very similar things used to be done to old vw motors too... hell there were some motorcycles in the 60's that came with a somewhat similar motor from the factory. Never claimed it was an original idea.

Holds up fine. The resin I'm using doesn't start to break down until it's way hot... 3-400 degrees F iirc. You don't see much as far as cf pipes go because they're expensive and very labor intensive to make typically. Much faster to just bend a pipe up out of metal.

I was wondering about this, when you said you were working small sections at a time, what kind of resin is it? Similar to the stuff they use for preperg cf? By the way this project is pure awesome:thumbup
