On Sep 22, a new go-karting circuit will open at Turf City in Bukit Timah. 

The Karting Arena is a 500m circuit consisting of 11 meandering turns. If you're going with a bunch of friends, choose the F1 race format, where only one will emerge champion, or drive at your own pace. Too scared to actually get on the track? Try out the racing simulators that let you choose from actual F1 racetracks around the world, or cruise down a virtual reality version of the Turf City racetrack. 

It's $25 for 15 rounds on the karting racetrack, and $10 for 10 mins on the F1 simulator.
