Unhappy

On Wednesday Smokey Yunick lost his battle with cancer and was laid to rest on Saturday May 12th.
Most of you guys probably affiliate Smokey with just Chevys but he was truly a pioneer in the field of automotive engineering; yet he didn't have a college degree. Unconventional and controversial but many of his innovations are in the cars we buy today.
Probably his greatest innovation was his Hot Air Engine but it was so unconventional but worked perfectly yielding 200+HP and 50 MPG from a 2.2 4 cyl; but none of the automakers would buy the manufacturing rights. In disgust Smokey shelved it and we really lost out on one of the greatest new developments in automotive technology in 100 years.


A legend; gone but never forgotten

Default Smokey Y.

I wholeheartedly agree everyone who loves cars and horse power should be saddened by Smokeys passing. He was always 10 steps ahead of everyone else. If you had to race against something Smokey prepared you were in trouble. A great number of rules in NASCARs rulebook came about because of Smokeys' innovations and craftiness.

He seemed to be a great guy..as far as his hot gas motor. Hotter fuel runs emmisions up..ie thats why higher compression motors usually fair poorly in emmisions test..at least that is my guess as to why they didnt like his engine....A Motoring Great, probably in the top 10 off all time...right next to Carrol Shelby, Tom Hoover, Duntov..

Smokey was one of a kind, many years ago a friend called Smokey to ask him questions about synthetic oils just after he was the first to run Synthetic Oil at Indy. He spend at least an hour of his time on the phone and also sent a case of the Synthetic that he used; as well as the direct phone number to the manufacturer of the oil (the presidents office of the corp). He gave a lot of technical info on the Indy car and the results of the engine wear. I used the oil for years and had excellent results on my hi-rpm engines. He will be missed by a lot of people.

Smokey's studies on how the cooling systems didn't quite work the way the engineers thought is one of his classic contributions:

Read this quote from the grapeaperacing.com website:

begin quote

"Basic Flow Modifications - Most stock systems will have a common outlet for both banks. The outlets of each bank flows directly at each other than must take a 90° turn to return to the radiator. If one side gets hotter (which is sure to happen) the pressure of that side will increase. The increased pressure will increase flow in the hotter bank and decrease flow in the cooler one. The faster moving coolant will cool the hot bank better and the slower moving coolant picks up more heat in the colder side. As you can see, the hot side is getting cooled and the cooler side is heating up. This happens until the banks reverse, the side that was cooler is now hotter and has more pressure. The cyclic flow will continue until the engine is shut off. Smokey Yunick was the first to do studies on the cyclic flow and traced the problem to the outlet. By tapping the front of the heads, and bringing the coolant together in a Y eliminated the cycling. Moroso now sells the Y outlet developed By Smokey Yunick and it is the single best thing that you can do (unless radical changes are made) to help equalize flow."
