A written warranty provides benefits for you and your customer. It sets expectations, protects both parties and is a great marketing tool that encourages repeat business.
High-frequency fatigue, also known as harmonics, are a ubiquitous challenge in racing engines and can potentially wreak havoc on the valvetrain if left unchecked. Well-designed valve springs play a pivotal role in managing this, ensuring essential stability, and minimizing wear on valvetrain components.
For racing, a common trend to eliminate the problems associated with hydraulic lifters are the use of limited or short-travel hydraulic lifters. A reduction in plunger travel, which is usually about half that of a traditional full-travel lifter, reduces the amount of oil required to fill the lifter, which in turn reduces the compression of aerated oil.
Determining the correct pushrod length is often regarded as one of the most intricate aspects of the selection process due to the variability in valvetrain geometry and design.
Not only are customers asking for higher quality, they’re also becoming accustomed to having to wait a little while longer to get it. And, on the aluminum rocker side of things, the trend for customers has been a desire for lighter rocker designs.
If you go back to the 1900s to 1940s, the common place to start WAS the camshaft lobe. Engineers and engine designers drew one circle for the base circle, one for the nose, and then connected the two with arcs in-between. Eventually that was improved by shifting their focus to the lifter or tappet rise from the base circle.
Understanding what’s going on in a combustion chamber and how to read what the engine is telling you through the spark plug is of utmost importance. If you can master that, you’ll keep your engine happy.
PPLUS Global Logistics, a freight management provider, recently released a guide outlining the proper steps for crating a performance engine for shipping. Obviously, given the expense and potential for damage to these high-value engines, shipping them requires careful attention to detail to ensure their safe transportation. These engines are not just valuable investments, they are
Not to be confused with twin-turbocharging, twin-charging is the innovative combination of a supercharger and a turbocharger. It’s nothing new – Lancia, Nissan and Volkswagen were among the first to use the combination back in the ‘80s, but it’s hardly common today.
If there’s anything all of us in this industry have come to understand, it’s that you can never be certain someone else did the job correctly – and when it comes to crankshafts and crank kits that you or a customer might purchase, it’s imperative to ensure a proper balance job was performed and not just trust that it was because it says so.
