Fuel injectors and the rails that hold them are just as susceptible to heat issues as the carburetors they replaced. Located on top of the engine, fuel rails see a lot of heat exposure. On late model vehicles this issue is further compounded by how compact and tight modern engine compartments tend to be, along with the factory engine covers that are all the rage these days, trapping even more heat that can be transferred to the fuel as it flows through the rails on its way to the injectors.
It tells your engine control unit (ECU), or simply “computer” how much air is entering the engine. The ECU uses that data to adjust the amount of fuel to deliver to ensure an optimal air/fuel ratio. Unfortunately, since they’re precision electronic devices, mass airflow sensors also have a reputation for being fragile.
There are several pet trackers on the market that can help you train your hunting dog or keep an eye on any pet that goes “off-leash” from time to time. Into bicycling? Take Patches along for the ride with a pet trailer for your bike. Available in several sizes and styles, they’re a great way to enjoy biking with your furry pal—unless your dog is coordinated enough to pedal a tandem. This is an engine specification guide for General Motors’ fifth-generation L83 and L8B engines that launched in 2014.
Upgrading the camshaft will require the matching valve springs. Titanium retainers are also recommended. They will reduce the valve weight and prevent valve float. The trunnion bearings in the stock rocker arms are a known weak point. We strongly recommend a trunnion upgrade kit. Swapping in a set of full roller rockers is another option.
Got a dog (or well-trained llama) too big to sit in a seat? A good pet barrier can keep them securely in the back—away from your steering wheel and Stray Cats CDs. Most pet barriers offer a universal fit, with adjustable legs that secure to your vehicle’s floor and ceiling. There are larger options available for cargo areas of minivans and SUVs, along with compact barriers designed specifically for the back seat of a car.
The cooler the fuel rails are, the cooler the fuel inside them will stay, which helps to improve injector performance and prevent power loss. With the AutoRama show rolling into Dallas, TX, auto photographers had their cameras ready and we were fortunate to get our hands on some of their work.
“I’ve been dreaming my whole life of winning the Winternationals, and it finally came true,” Gilley said after winning his fourth career Wally. “[In a heads-up], you just let everything hang out on these things. You put the lightweight oil in there, you ice it down, you compensate for your reaction time because you know the car is going to leave harder. You just keep your foot on the floor and hope you’re the first one to the finish line. It was a great day.”
“Words cannot describe this,” Will said, after defeating veteran racer Kyle Seipel in the final, 6.043 (6.01 dial) at 234.13 to 6.862 (6.81), 197.74. “I’m totally excited, and there are so many people to thank for helping me get to this point. I have to thank the fans for showing up. It makes it even more special.”
