This is from a track that had a brief life out in Boumont California. Moran raceway. RIP
I raced in the Rotax Max series. I've done a bunch of HPDE weekends prior to getting into karting. The karts will teach you much quicker than a car will.
Richard Hearn had a pretty cool thing out here prior to his death. He ran a series that ran on spec briggs & stratton engines and spec brick like tires. It was a 6 hour enduro that would be open to any group that had $600 to spend
You would show up with a rolling chasssis. Pick a poker chip with a # on it and get a engine. The gas tank was good for 20-25 minutes and you needed to change drivers, re-fuel and get out in about 20 seconds. Two times during the race you would do a oil change on the engine, they ran on methonal which ruined the oil pretty quickly. I'm pretty sure that we would do a refuel and oil change in under a minute
The speeds were in the 50-55mph range but since the tires where less than grippy it was a hell of a handfull.
There's another enduro series that's out at Fontana speedway that runs a simelar class but they do the refuel for you as well as the oil change.
Would any of you SoCal guys like to form a team? I'll get info.
