When last we met, Thunderhill Park was about to open its doors, participating in the birth of a race track and joining the harsh reality in motorsports venue operations. Like most new parents of a neonate, we weren’t exactly sure what we were doing. The track was done as far as we could go. We had a trailer for timing and scoring and another trailer which was basically a place for the stewards and for Pauline Laskin and her race central crew at the grand opening. The track had no curbs and remarkably few walls. The chosen weekend was Halloween and the San Francisco Region of the SCCA was ready. Since 1988 the Club had, in varying degrees, anticipated this event. The buzz within the road racing world and the local community was at an all-time high.

Toyo Tires will offer a new open tire contingency program to all Enduro classes during the 2013 regional racing season. The new contingency program will be available immediately and like all Toyo contingencies, it will be available to Enduro entrants competing on the Proxes® line of Toyo tires.

This new offering to the expansive Toyo contingency program in 2013 increases the available contingency from Toyo Tires to a whopping $10,000,000 in contingency value to NASA racers. One very important note about this new program is its availability to current Toyo contingency participants in other classes. Product awards are available to competitors in addition to any regional Toyo contingency they may have qualified for during the same day. This program is separate in nature and eligible for contingency awards even if a competitor may have already qualified for “Toyo bucks” during the same day. Simply put, if you usually run in a regional sprint racing class on a Toyo tire and collect contingency, you are now eligible to join the ranks of the Enduro competitors and vie for contingency in those classes as well!

If you have been reading the story of Thunderhill you know we are up to the part where we start construction. We had just gotten permission to build the track and the period of notification to the local area had passed with nary a single complaint. The next step before construction was to announce the successful status of the  track effort. We did this through a video and a site visit plus Wheel press. The  video was made using a helicopter to fly over a track carved into the landscape that sort of replicated the design created by Steve Crawford. We shot the video by hanging off the runner of the helicopter as it followed the path of the track plowed into the earth by our new neighbor Thor Oden. We still have that video. We showed the video at the SCCA banquet in 1992 and we issued press in the Wheel. I think Club members were pleased with what they saw and heard but there were still those folks who thought that Willows was too far away and that this would be the death knell of the project. The original parameter for location was one hour from the intersection of 580 and 680 in Pleasanton.  It had to do with travel time.

Be advised Thunderhil Raceway has a 103 sound limit and mufflers are required. We wanted to remind you of these requirements and let you know they will be strictly enforced. This means anyone attending events at Thunderhill should be fully prepared to follow these requirements. If you are over the 103 limit, you will be blacked flagged. Thunderhill will then give you an opportunity to correct the problem. Once you are back out on track, if you are still over the 103 limit you will be asked to trailer the car or motorcycle for the rest of the day.

We wanted to give you this friendly reminder so you can come prepared and are not caught off guard by sound issues. As always we want you to have a great experience whenever you attend events at Thunderhill Raceway!

Thank you,

Thunderhill Management

Willows, Ca. February 14, 2013….. Alternative Energy Systems [AES] a Chico based solar company is ensconced at the local Thunderhill Raceway Park in the process of installing 314 solar panels to the already diverse energy program at the Willows road race track. The $336,824 project began just a week ago and is schedule to bring the facility to a point nearing grid-neutral status when combined with the track’s three wind generators and the pending solar field to be located on 133 acres of property north of the raceway. “We are very excited about this project and what it means to the image and energy use of Thunderhill Park,”  noted track energy expert Stuart Seitz.  Seitz is a 2010 graduate of Chico State and three-year employee of the raceway located at 5250 Hwy 162 in Willows.
