It’s hard to believe that another week has come and gone. It’s true when they say time flies when you’re having fun. Now that Thursday has hit us straight in the face and the end of the week announcing its arrival, it’s time for another Throwback Thursday.
This week, I decided to take a step back to August 2016, to check out, Quick Lift – What It Is And How It Works With Crane Cams. Way back then, Kyle Kitchen had the chance to speak with Allan Bechtloff of Crane Cams to get a quick history about its “Quick-Lift” design found in its Gold Race-series rocker arms, and how the design was discovered.
“When this style rocker arm was first released and before we had a name for it – whether by accident or design – it was immediately noticed that engines running this style rocker had more pickup and more power than others, but no one really understood why,” Bechtloff continues. “Many people assumed it was just because the new rocker was more rigid. Once people really started to investigate this phenomenon, it was discovered that it wasn’t just its rigidity, but the rate at which the valve moves had been slightly changed as well, and the engine liked it.”
In the original article, Bechtloff explains if you have a rocker arm with a 1.7 ratio, with Quick-Lift, the valves will initially open with an increased ratio of 1.78, and then drop to a 1.7-ratio right around mid-lift. Then, snap shut again at an increased ratio. This quicker valve-opening rate allows more time for air to fill the cylinders, increasing power.
There’s a lot more information to be explained, but the premise of this performance-enhancing product definitely makes it worthy of a second look. For that reason, I selected Quick Lift – What It Is And How It Works With Crane Cams as this week’s Throwback Thursday showcase-article.
