Here is a site I came across and wanted to share with the tilted motor folks......1/4 scale V8 engines. One with overhead cams, another with a mini blower, and one hell of a price tag!! All in all very cool, from reading the stats I assumed more HP(1/4 scale 1/4 the horsepower?). The first link has a video with it running, it sounds I think really cool just like the big one , but smaller.
Now I think they use these in 1/4 scale remote control cars which is shown on the second site
Well check it out let me know what you think!!!
