Test & Tune
These are evenings the track is open to anyone and everyone to race down The Fastest Track in Michigan! It doesn’t matter if you are driving a fast racecar or “mom’s grocery getter”, anyone can drive down the racetrack. These events are offered on specific Wednesdays and Fridays. The open Test & Tune evenings on Wednesdays and Fridays are a fun way to test and tune your vehicle or race against others if you choose. These are throughout the season and once a month during the Test & Tune/Fun ‘n Grudge US 131 features a Venom Midnight Madness.
Participants will not want to miss these bargain nights with lots of track time. The US 131 Motorsports Park staff will be available to assist anyone interested in learning more about drag racing and bracket racing. We will run open time runs for the first part of the event. Drivers will then be able to place a dial-in on their car, if they choose, and run just as if they were running in an actual bracket race. All just for fun to see who can take the win light!
Friday Nights include an open Test & Tune for any and all vehicles, novice or seasoned racer. Similar to Wednesdays, drivers can make unlimited time runs all evening and pair up against other racers for grudge matches. Whether you want to just test your vehicle, run against one another or just hang out with friends this is the place to be on Friday nights.
Venom Midnight Madness
Both the Fun ‘n Grudge and Venom Midnight Madness events are the ideal place to take it off the streets and onto the track in a safe, controlled and accurate environment where racers can battle it out. Who can argue with a win light? Unlike illegal street racing, there’s no room for error with US 131 Motorsports Park’s modern timing system.
