Toyota’s New Cloaking Device
Did Toyota Really Just Patent a Cloaking Device? The headlines sure suggest they did. Toyota patent reveals ‘Cloaking Device’ for cars Toyota Just Patented a “Cloaking Device” Other outlets were a little more, ahem, transparent about the story Toyota patents a device that could make car pillars transparent The folks […]
Changing Manufacturers: More than just Decals?
I’d Rather Fight Than Switch If you remember what commercial that was from, then congrats. You are — like me — old. It used to be that an owner was loyal to his manufacturer to the death, but the last few years have seen some big switches in manufacturer affiliations. […]
Will Toyota’s New Nose Change the Cup Series Balance?
The unveiling last Monday of Toyota’s new redesigned race car for 2017 got a little lost between Junior’s wedding and Carl Edwards’ surprise ‘stepping back’ from NASCAR. But every time a manufacturer redesigns and engine or a body, it opens up a giant task for NASCAR. The Level Playing Field A […]
Did EFI Make NASCAR Engines More Reliable?
In 2012, NASCAR moved from carburetors to Electronic Fuel Injection (EFI). This made people like me happy because my friends who denigrated NASCAR as hopelessly outdated and behind the times have one less argument to use against me. There were many purposes for the switch to EFI: one was precisely as I note above: to be […]
2015 Rules Changes: Testing
One of the biggest changes NASCAR has instituted for the 2015 season is eliminating individual team testing at any tracks. In 2014, teams were limited to four tests and were not allowed to test at tracks that were included in the schedule. NASCAR may run some limited tests, but they won’t be having the week-long marathon that was Daytona Speedweeks.
Dive! Dive! Dive Planes… on Stock Cars?
A persistent motorsports issue (and not only with stock cars) is the aerodynamic passing problem. You can’t pass without grip. Grip is a direct result of downforce. Downforce comes from two places: the weight of the car (mechanical grip) and the billions and billions of air molecules hitting the car (a.k.a aerogrip).
The Virtual Reality of Racing Simulators
You are hurtling down the frontstretch at Michigan, your speed approaching 215 mph. Your seat moves up and down as you hit the seams, but your focus is squarely on getting into Turn 1 losing as little speed as possible. You squeeze the brakes and feel yourself moving forward, only to realize that you’re still moving too quickly. As the car starts to head toward the wall, you panic and squeeze the brake even harder.
The car snaps loose and the next thing you feel… is an engineer’s hand on your shoulder. You turn around to see her barely suppressing a smile.
Toyota Engines: By The Numbers
There are somewhere in the vicinity of 840 parts in a NASCAR Sprint Cup Engine (at least the Chevy version and yes, I am taking someone’s word for this. I did not have time to sit down and count all the pieces.) The relevance of this is that if any […]
RPM, Roush, Murphey the Mustang and the Pride of Ownership
I was 14 years old the last time I stood in line to get an autograph. It was at the Target store in Brookfield, WI and a chance to have my album cover signed by Boston (the band, not the city). The only reason I went was that a group […]
Engine Blowups: A Consequence of the Testing Ban?
The stock car science blog has been a little behind due to a really big project I’ve been working on that has taken up every spare moment of writing time the last few months. The good news is that there (finally) will be an announcement at Texas Motor Speedway the […]
