On October 9th, Clayton L. Neuman (age 73) oldest member of the original Neuman Racing Team of Minnesota, passed away after fighting a battle with cancer for 10 months. Clayton was a drag racing fanatic, and a fantastic engineer. He participated and attended many ISR World Series events, MSDRS events and traveled to Regina, Saskatchewan; Winnipeg, Manitoba; Riverton, Wyoming; Wisconsin; Iowa; and Michigan in support of the Neuman Racing Team.
In the 80’s, he can be remembered for his innovative rotary valved Arctic Cat motors with carburetors mounted on the front of the engine crankcases. Later, he developed his Arctic Cat based lay down, opposed 4 cylinder 800 engine.
Our own Dragcat from the Bull Sessions (AKA Paul James) had this to say about Clayton:
Clay began his racing career in 1972 when he bought a 72 Arctic Cat Puma. He had it modified by Amenrudes Performance, complete with Salisbury clutch and Hooker exhaust. They brought it to a local drag race, and it was driven by smaller and younger Lloyd Neuman. The machine won the race and the Neuman race team was born!
Bitten by the race bug, Clay next bought a 72 ext 650. Unhappy with its performance, he secured a more powerful 73 650 (pictured) and raced it all the way through 1976 against the likes of Marv Jorgenson and Bill Reynolds.
Sometime in the late seventies the engineering bug bit and he designed his own version of the 77z 250 motor. This engine featured crankcase mounted induction on the front of the motor along with special port design and other features I cant mention {wink, wink}. There was people in the shop taking bets that the motor would never run. Well, run it did, driven by Clayton’s son Steve, this little machine dominated the 250 classes for several years. Later a 340 was also built to this design and was driven by Clay.
in 1990 the bug bit again and he designed and built the 800cc opposed 4 cylinder sled that is pictured below. It was driven by Steve the first few years, and then by me for over 10 years to its retirement. This machine was experimental and served as a test bed for many ideas good and of course some not so good!
Clayton along with brothers Lloyd, Gordon and Frank made up the Neuman Race Team – a well known and dominant force in snowmobile racing for over 30 years. Personally I’d like to add that Clayton was a great teacher, boss, and all around great friend to have. I will miss him dearly.
