Hitting the Rollers With Our M235i

Update by Tom Suddard to the BMW M235i project car
Sep 16, 2014

Ah, the dyno. It's the perfect place to objectively measure a car's performance.
We tracked the air/fuel ratio during each pull so we'll have a reference point for future modifications.
And, of course, we tried some of our favorite magic juice: EFS Combust.

Before we did anything else to our Project M235i, we wanted to see what we were starting with. So, we visited the Superchips dyno and made a few pulls. Our only modification (for now) was a fuel additive called EFS Combust.

The result: 306 horsepower and 331 ft.-lbs. of torque. That’s certainly an interesting place to start.
