Original Unrestricted 2019 @ Grattan Raceway

The only race in June for Jenkins racing; we made the 1350 mile round trip to Grattan Raceway Park in Belding, Michigan.

Visiting a track for the first time is always a lesson in execution. Everything needs to go smoothly to get the data flowing in order to get on pace as quickly as possible. This trip went exactly the opposite.

Friday’s testing ended on session two of six with a broken CV axle that couldn’t be readily sourced. Repairs were finally finished at 11 PM, long after the last checkered flag.

Saturday was about collecting data and comparing it with some friendly local drivers. We qualified mid pack which was an achievement considering the previous day’s mechanical problems. The race was an intense mid pack battle on Grattan’s tight and technical turns that really pushed the limits of the number 21 Bühler racecar. Analysis showed several key corners where the minimum speed needed to come up in order to improve for Sunday.

Improvements were made for Sunday and qualifying position improved slightly. Unfortunately a botched start by the group resulted in rough impact. Less than two laps later third gear let go and the transmission was badly damaged. This ended the weekend at Grattan with a DNF.

Grattan Raceway Park is a tight, technical collection of hills and turns that takes a team effort to tame. The data collected by Bühler hardware was critical in enabling a rapid pace improvement despite mechanical setbacks.

Many thanks to Bühler Prince in nearby Holland, MI for the invite to beautiful Michigan. Check them out for all things Die-Casting.
