Tom’s Corner – The Technology Behind Smokey Yunick’s Hot Vapor Fiero


After having presented an article on Smokey Yunick’s ‘ hot vapor engine’, I will attempt to explain how this technology works. Normally different parts of a standard non=homogeneous air/fuel mixture burns at different rates within the same cylinder creating turbulence and colliding flame fronts. Under normal running conditions, cooling the intake charge to create higher mixture density is beneficial to keep some of the fuel molecules from undergoing spontaneous combustion or denotation.

Smokey installed a heat exchanger under the carburetor that used hot engine coolant exiting the motor to warm that mixture to around 200 degrees. Then the air/fuel mixture flowed through a second stage generator, an exhaust driven turbine wrapped in exhaust gas ducting. He called this devise a ‘homogenizer’, but it was really a turbocharger underneath that fancy ducting ! Not only did this devise generate boost, it also served as a one way check valve to keep the expanded hot gas from back flowing out of the carburetor. Then from the turbine the mixture flowed through an intake manifold also wrapped by exhaust ducting to reach its final super-hot temperature. Smokey’s engine had all the usual hot rod items of the period such as trick rings, forged pistons, Carillo connecting rods and so forth. One of the key secrets is the exact tune-up or technique used to get the engine past the detonation threshold to the super-hot, super-lean running condition. In short, an engine makes its most power running on the verge of denotation.

The key seems to be getting safely past 2250 degrees so not only is the tune-up critical…some special cam shaft timing is involved as well. Typical small block GM engines run very reliably at 1750 degrees F stabilized exhaust temperature. At 2250 degrees you are definitely in trouble from engine destroying denotation.So if you can get it to 2600 degrees or beyond you can control the burn rate of the hydrogen molecule in the fuel which is the major radical in the gas which causes denotation, you will make more power without denotation. Since the fuel economy standards are to be raised in the next 10 years, the auto makers are getting heavily involved in ‘heat vapor’ technology. Smokey was way ahead of his time and experimenting on a Fiero is another reason why this car is considered a true time capsule by the automotive industry ! I hope you enjoyed this small part of Fiero trivia.

Editors Note: Sorry for the delay in part two of Tom’s series on Smokey Yunik’s Fiero. Entirely my fault as I was busy looking for a new day job. There was lots of debate regarding the Smokey Yunik Fiero when the Tony Allers re-creation was re-discovered. You can read some of that debate at . The car even made an appearance at one of Ed Parks open houses at The Fiero Factory. — Jeff Jones, Editor

Tom’s Corner – Smokey Yunick’s Hot Vapor Fiero

Every year, someone asks about the fate of a potential break through engine technology developed by legendary racing engine builder and high performance tuner, Henry ‘Smokey’ Yunick, with his long time partner, Ralph Johnson. In the June 1984 issue of Hot Rod magazine, there was a report on a ‘hot vapor’ motor that Smokey developed using a 2.5 litre ‘Iron Duke’ 4 cylinder Fiero engine that met all the ‘80’s emission standards, made 250 horsepower and 250 Lbs/foot of torque and went from 0 to 60 in 6.5 seconds and got as high as 51 MPG using premium gas!

The ‘hot vapor’ engine did all of this running unheard of high temperatures at an extremely lean air/fuel fixture ratio, which was seemingly in violation of accepted internal combustion engine physics. Traditional theory was to get rid of or manage heat. Smokey was channeling heat for improved performance, the exact opposite of conventional engineering science. Here is how Smokey did this : A standard four cycle internal combustion engine utilizes only about 25% of its potential energy to make power. The remaining 75% is lost out the exhaust or transferred as heat into the cooling system and radiator. Heat vapor technology attempts to recapture this heat energy using it to super heat the incoming air/fuel mixture to more than 400 degrees F going into the cylinder, thereby achieving a perfectly vaporized condition that it said to prevent denotation while ensuring complete combustion. Smokey was channeling heat from the water in the engine’s cooling system plus exhaust heat to progressively warm the system’s induction flow to the required temperature. He and Ralph Johnson were actually fooling around with this concept for more than 3 decades. Smokey did take out patents on the basic ‘hot vapor’ technology but took much of the knowledge with him to the grave.

As for the fate of the original ‘hot vapor’ engines, his daughter Trish still retains 4 different prototypes in long term storage, one is also in the Smithsonian Institute. A friend of Smokey’s, (Tony Allers) has the only good running engine. He built a Fiero that is identical to the original car, using the original drive train salvaged from the original Hot Rod Fiero by Smokey before Smokey returned it ti Pontiac for crushing. Allers drove his car for 2 and ½ years before donating it to the Don Garlits Museum where it is currently on display. This Fiero can smoke the tires at 60 MPH and passes all Tennesee emission tests. ‘Hot Vapor’ technology will not die. The time will come when engines will be fully adapted as a heat pump.

(editors note: This is the first of a 2 part series on Smokey Yunick’s Hot Vapor Fiero. The next Tom’s Corner will look more into the Hot Vapor technology and some of the debate about the effectiveness)

Tom’s Corner – Cruising

tomscornerA few years ago, our Fiero club (The Fiero Fanatics ) did a car show in Manitowoc Wisconsin and we stayed at a motel on the Saturday before the show. It was a lovely evening so we decided to take a cruise into town to a local drive-in for something to eat. This place turned out to be a local hang-out for the local car clubs to congregate every week-end and we were very surprised to find a huge selection of hot rods, custom cars and sports cars in attendance. I enjoyed this experience very much and it got me to think…why not do this more often ?

As you probably know, there are a myriad of drive-ins around our area in which to do this all summer long. Usually when we do a car show, we get flyers from other car clubs for up-coming events, but lately cruise-in flyers are becoming more prevalent as well. You can go on line to check out an event you may want to do if your time permits and the weather cooperates. All summer, there are cruises planned for other cities and towns in our area. Sometimes, it’s just a spur of the moment decision to hop in your Fiero and go out to eat and see the other cars at these cruise-ins. This can be a wonderful way to break up a week night.

Our Fiero club combined with the GTO club to cruise out to a car show in Madison recently and take the back roads. You should have seen the people look at all our cars as we traveled through the small towns to get to the show. This is another facet of our car that is overlooked and perhaps we can cruise together this summer if time permits to a drive-in near-by and enjoy each other’s company and check out all the other cars that assemble for a night of fun !

Check with your local club and see when their next cruise is, or organize one!

2015 Dells Run

As always the Dells Run provided four days of fun the weekend after Memorial Day!

On Thursday it was great catching up with many friends I had not seen since the previous summer. It was a lovely evening for a nice cruise and stop for dinner

Friday was a fun and busy day, starting with breakfast at Stuffs, then a trip to Baraboo Wisconsin for a private tour of the Ringling House and historic theater. The evening was capped off with a nice dinner followed by socializing at the Chula Vista Resort.

Saturday is show day at the Dells Run. Unfortunately most of the day was spent dodging rain drops. The rain did finally clear and a great show was had. Sunday morning it was time for awards and then goodbyes. The long weekend always goes too fast.
