Racers are a punishing lot, right? During competition they are using their machines to go as fast and as hard as possible, pushing the bounds of physical and mechanical endurance. What do they do when it is over? They go even harder! Drag racers will rip the throttle in celebration, stock car racers will blow donuts while clipping the rev limiter, and the dirt bike guys? Hell, they just straight up try killing their stuff on purpose. It’s the hot new thing to turn burnouts run their engines to death in a free-wheel fashion, and generally finish the job on a bike that has bene ridden half to death in a race already. Well, in the case of this video these dudes tried and failed to kill their bike. Why? Because JE Pistons, that’s why.
It’s amazing to see how nice this piston is after the wanton hatred thrown at it by the team. 10 straight minutes of running full throttle and the thing could be used in a race motor again tomorrow. That’s quality materials, amazing engineering, and the fact that severe duty is the only duty that JE designers and engineers plan for their product to see.
This is not the type of test anyone conducts themselves in the industry but it is the kind of test that JE Pistons can pass because they’re constructed to last and to win. This is wild!
Underachiever. With my N2O tuning skills I could blow a hole in that slug in less than 8 seconds!
Meh.
Back in 2005 we where at Yamaha’s racing test facility and saw many things one of was a 450 cc dirtbike engine on the dyno. It was on the second part of their test to certification of an OEM high compression ‘racing only’ piston. They had already run it for 24 hours @ 75% load @ 8000 rpm and now it was the 24 hours @ 100% load and 10k rpm..!
It passed and was later available at all Yamaha motorcycle dealers.
