Rudezon 2 stroke V8 (Page 2 of 2)

We're running a Mountain Max 700.

The hot ticket would be a fuel-injected liter twin, preferably direct-injected.  I like (well, in theory anyway) the sound of our triple, but I do get tired of jetting all the damn carbs, and the twins make their power lower down, which would better suit our final drive ratio.  We're geared to like 183 MPH at the moment.

Another nice thing about triples: when you drop a cylinder you can just re-clutch for the lower horsepower and keep racing.  Not that we've had to do that more than twice.

There's a build thread around here someplace.  I think John called it something like "How we built Balto the wonder Miata".  I don't recall whether it has been updated for the Yamaha re-power or not.  The car originally (well, not _originally_ originally) had a Polaris 600XLT in it.  Interesting engine, very kerplodey.

The car will spin the tires from a dead stop.  We autocrossed it once and it was launching harder than the Z06 that was right ahead of it in line.  Yeah, I had to trim the kevlar "hairs" off the sides of the belt after every run, but that's beside the point

An underdrive unit would be nice just to let us use more of the available range of the clutch.  Right now we live in a very narrow part of the range and it wears stuff out.  Also, the snowmobile belt drives are most efficient just below 1:1, so having that be a little below our practical top speed would be cool.  It maths out to 135mph at 1:1 as it stands.

But, you know, weight.
