Cool Engines

 

Thats kewl! How much? Where from? What kind of oil/fuel do these require? I'm sure they would be a blast to build and run!

They are pretty expensive, in the neighborhood of $4k. But you've got to admit, it would be a kick ass toy to have and impress people with. Take a look at this site, it has video's of miniature V8 with roots-type superchargers running on a stand. It is amazing how these things sound. I am trying to locate the video of the 1/8th scale cobra with the ford panhead v8. I saw it on TV once and the guy was doing insane burnouts with that car

Cool site to see Model V8s (blown) running

 

That's pretty cool if you have money to burn.

 

There is another place that builds these... I lost the pamphlet tho, I believe it started with a "C" (yeah, alot of help THAT is!) but they were even smaller and funtional!

They sold them as a kit, would've been great to build, about $2.5k
