Check Out That Glow! The Brakes Get Hot When A 3,300 Pound Nova Lost It’s Chutes On A 200 MPH Pass
Sometimes bad things happen, no matter how prepared you are. Limited Drag Radial record holder Justin Martin learned that lesson last fall at No Mercy 8, and the guys at Motion Raceworks just happened to have a camera under the car to show what happens when you have the best components on your car in case of disaster.
Martin lost the chutes on his car after laying down a pass in the 4.teen range at over 185 MPH. While there is quite a bit of shutdown at South Georgia Motorsports Park, when you’re behind the wheel of a 3,300 pound car traveling at nearly 190 MPH, things get hairy pretty quickly. Martin jumped all over the brake pedal, expecting the brakes to slow the car, then fade and leave him with little in the way of stopping power.
Thankfully, he installed brakes from TBM, which just happen to have a “state of the art design that allows thermal efficiency and the incredible clamping force of the TBM calipers created no brake fade and allowed this car to race another day” according to the caption on this video, posted to the Motion Raceworks Facebook page.
“On a traditional round steel plate rotor, the heat differential from top to bottom on the rotor face under braking causes them to bevel over and/or warp,” the caption continues. “The shape of TBM’s revolution rotor is designed to have a consistent thermal cross section as you can see in this video (there are no hot spots), equalizing the temperature as the rotors heat up. This is what allows their rotors to stay flat (not taper or curl) and live longer than a tradition round plate rotor.”
What all this means is, despite the tremendous strain put on the brakes by the loss of the chutes, Martin was able to get the car stopped safely and come back to continue his run through eliminations. That, my friends, is some cool science!
WHOAA!!! The Science behind TBM Brakes
This is insane!! Want to learn more about why TBM brakes are able to stop A 3300 lb radial car that loses its chutes at 190 on a short track and keep going? Watch this video and read the description below the video! Link in comments below!When Justin Martin lost the chutes on his 4.1x @ 188 mph 3300 lb Nova on a short track last fall he thought he was going in the weeds without a doubt. We have all seen these stories play out with racers doing a donut to stop or simply going off the back of the track. What he didn't count on was just how good the TBM brakes that he installed earlier that year really were. The state of the art design that allows thermal efficiency and the incredible clamping force of the TBM calipers created no brake fade and allowed this car to race another day. Please read on for the science behind them. TBM Revolution Rotors don’t just look cool but they can handle the heat. Originally designed for use in the dirt circle track world, almost 30 years later, these eye catching components are now taking the drag racing market by stormOn a traditional round steel plate rotor, the heat differential from top to bottom on the rotor face under braking causes them to bevel over and/or warp. The shape of TBM’s revolution rotor is designed to have a consistant thermal cross section as you can see in this video (there are no hot spots), equalizing the temperature as the rotors heat up. This is what allows their rotors to stay flat (not taper or curl) and live longer than a tradition round plate rotor. TBM rotors endure a week long thermal process to stabilize the molecular structure of the material thus preventing too much material movement during temperature change. With this unique rotor design there is always at least 2/3 pad rotor contact, so the effective radius of the rotor stays in tact. Giving you the same leverage as a round rotor of equal diameter. Being able to remove weight with the convoluted design allows TBM to go thicker and larger in diameter in certain applications, all while giving you a lighter option than their competitors.Pairing these rotors with TBM’s rigid steel insert caliper design not only gives you an extremely lightweight system with high performance stopping power and durability, but are sure to compliment your wheels perfectly.
