In 2002 Tom and his wife sold their toy company and headed out to tour the USA for a year on a motorcycle with a 22 cubic foot trailer. On July 3rd at 9:00 in the morning with three months, 29 states and 19,000 miles into the trip, the motorcycle was tee-boned in an intersection by a motorist in a hurry. Putting 44 years of motorcycling behind him, Tom went for a 4 wheel replacement. Testing the S-2000 Honda and the Mazda Miata, the choice was easy. The Miata was more fun. Not as fast, but more fun nonetheless.
After a couple months touring with the Miata and towing the motorcycle trailer, it was easy to see that the Miata needed more low RPM torque to climb hills. In 2003, Tom found a company selling a "Hotside" MP62 Eaton supercharger kit and did the deed. It seemed to be a bit temperamental with idle issues and other quirks so it was time to pull out the computer and Solidworks and start over. As most superchargers from his youth were intake mounted and force fed the engine, the Coldside appeared to be the solution. Move the blower onto an efficient, high flow intake manifold, away from the high exhaust heat, and most importantly, eliminate the need for an intercooler.
In 2004, the pieces and parts were drawn, machined parts went out for CNC and molds were constructed for the cast parts. With sample parts in hand, the hotside 1999 10th Anniversary Miata became a Coldside 1999 10th Anniversary Miata. After time messing with Water/Methanol injection and typically having an empty water bottle when the need for speed arose, he decided to try fuel. After all, there was 12.5 gallons of that on board and, if it ran out, the engine would simply stop rather than break. With a lot of EGT, dyno and track testing, a 10 PSI boost kit hit the streets. Prototype kit hit the streets in late 2004 and the production version in early 2005. The kit produced roughly 200 HP at the wheels and a torque "curve" as flat as a table top, producing only slightly less torque at 2500 RPM than 7000 RPM.
The next step was to work on California Air Resource Board Executive Order testing and approval for emissions. We bought a 2005 Miata for the testing in late 2005 and Christmas of 2006 we had our CARB EO# D-617 in hand at 10 PSI on a stock 2005 engine with around 200 HP.
And now, 2013 brings us to 300+HP and 220+ FT-Pounds of torque "Green" setup that you can drive to work 5 days a week; drive to the track, autocross or drags on the weekend and then drive home.
