swampbrat Posted August 18, 2010 Share Posted August 18, 2010 I just had my memory jarred by a recent issue of HOt ROD magazine. Smokey Yunick died while I still lived in Florida (not far from his shop) .While they were having a big garage sale of performance parts , the newspaper mentioned they would not sell his 80mpg Ford aspire with a hot vapor engine. The new issue of hot rod has an article on a hot vapor fiero a guy put back together. It makes 1.8hp / ci and gets 60mpg. Basically it heats the intake charge until it is 450 deg f entering the cylinder. Actually too hot to cause engine destroying detonation. Anyone trying something like this or just heard about it?

baccaruda Posted August 18, 2010 Share Posted August 18, 2010 I read a little about Smokey a while ago, including the hot vapor stuff. http://en.wikipedia.org/wiki/Smokey_Yunick One of the all-time greats Quote Link to comment Share on other sites More sharing options...
LPGsuperchargedBrumby Posted September 6, 2010 Share Posted September 6, 2010 there was a local here that did a very similar engine a few years back....the engine went well once it was up to operating temperature got around 90mpg in a 4runner....it had two downsides....one it couldn't be driven until it was up to full operating temperature which took about 15-20 mins from a cold start...second downside was the fact that it had to use funny coolant that didn't boil and a lubricating oil normally used in a gas turbine due to the high temperatures that the engine was run at Quote Link to comment Share on other sites More sharing options...
