In any case, he (Yunik) has a Rabbit with a two cylinder engine he built. It gets 60mpg, with no performance degradation. Actually, he claims to not be too proud of that since he has a three cylinder version in a 3100 pound Buick that gets 50mpg. There's also a three cylinder version in a DeLorean that does 0-60 in two seconds less than the stock version. The interview didn't give a great deal of technical information. The air/fuel mixture is preheated to around 450 F (presumably by the exhaust, but it wasn't clear). There is an exhaust driven turbine used to drive the preheating equipment; it was unclear whether or not it's also used to boost the air/fuel mixture itself. A normal carb is used, and it has a standard (i.e. not electronic) ignition system. They drove the Rabbit around some; the interviewer claimed that there was no increase in engine vibration over the normal Rabbit engine (I don't personally know whether or not that's damnation with faint praise, having no experience with Rabbits). Engine weight was claimed to be around 170 pounds (I think). The engine is being developed in conjunction with something called (I believe) "Southwest Research Labs" in San Antonio, Texas. It not only runs, it has actually been certified. Does anyone have any better information on this? Perhaps someone in/from Florida (where Yunik's shop is)? The thing that impressed me was that this wasn't some nut simply making claims. Yunik (it really annoys me that I can't remember whether or not that's the correct spelling - would somebody please let me know?) is *very* respected in racing circles and has been for 30 years or so. The engine exists, runs, and has been certified. Seems to me like there may be a truly significant advancement in engine technology in the works here.
