Probably Jimmy's most famous race ever was the one Indy
race (1955) in which he was supposed to driver the Sumar Streamliner. A
Kurtis-Offy 500D with body panels making it look like a Le Mans style sportscar.
Poor Jimmy felt so claustrofibic within the bubble covered cockpit and so
insecuer that he couldn't see the steering wheels move that he discarded all the
streamlining equipment and ran the car as it was. Not the neatest lookings of
cars anymore but he qualified and raced it. Graham
Clayton from the Nostalgia Forum at AtlasF1.com: "One of the more unusual strange looking cars was the Sumar
Special driven by Jimmy Daywalt in the 1955 Indy 500. The car had a full
streamlined sports-car type body. "The first time out for a practice run Daywalt had the bubble canopy over his head, but it was off Monday when the local driver reeled off a 131-plus practice try. It was explained that the friction on the plastic bubble was causing dust particles to smear and hamper his vision. Daywalt said he also experienced some trouble with the leather padding flapping around in the cockpit. As for the fenders, the biggest problem is how to check the wear and tear of the tires during the race. They say the rubber will be checked by touch rather than the naked eye and this is one big reason why Daywalt will probably spend a lot of time out on the track during the practice period." "Reports from 'Gasoline Alley' are that the new Sumar car is a 'flop,' but Daywalt still thinks the car can go, if the mechanics can get the 'font-end condition' that has given him so much trouble on the turns straighten out. The car Daywalt is to pilot has attracted a great deal of attention with its fenders and bubble canopy. The latter part of the car, probably won't be around Saturday, but the fenders will be there. There was some doubt as to whether he'd be able to get the 'feel' of the car with the wheels covered, but if he qualifies come race time they'll open little windows to expose each tire."
"Most observers and Daywalt himself were of the opinion that the body design of the Kurtis-Kraft car was a little too much 'streamlined.' There was plenty of power in the Meyer-Drake engine under the hood, but the wind conditions in the turns offered plenty of resistance to both the racer and the driver. An airplane designer from the Allison Aircraft company was present at the track last Sunday and Daywalt upon consulting the former was advised that some body and mechanical changes could be made to remedy the situation..... The Sumar Special looks like a fugitive from a jalopy race, but everyone agrees that looks aren't so important, but getting in the 'big' race is."

that it would run an Indy race at the new Daytona speedway. With Marshall as his
test driver, Chapman Root entered the Sumar Special. The goal was to attain a
speed of 180 mph.
