D&M Racing built this 950 cc Rotax 900ACE inline-three capable of 650 whp on methanol for Side-by-side (SxS) drag racing. The little motor features a WSI 900ACE billet block with a BC 73.5 mm crankshaft, BC I-beam rods, and CP pistons. On top sits a Total Performance Racing Industry head and BC solid bucket camshafts. Boost is generated by D&M Racing’s Xona Rotor turbocharger kit and sent directly through a Whalen Speed R&D Ghost billet intake manifold with six ID 2600 cc injectors.

I bet you can put this engine in a small car.
We hope someone does.
Oh man, this thing in a Honda Beat or Suzuki Cappuccino, or Autozam AZ-1 would be the stuff dreams are made of.
What transmission they they connect it to? I assume they had to make a custom bellhousing for it.
I’m going to sound dumb asking this but, is this engine 4-stroke or 2-stroke. It looks like a 4-stroke and the power levels wouldn’t be as high if it were a 2-stroke. Correct me if I’m wrong.
Hi Don. The Rotex 900 ACE is a 4-stroke engine.
