把冷启动问题抛在身后:最好的售后电喷系统

就像其传奇的4150化油器，霍利的狙击手电喷是一个明确的选择，为这么多的构建，没有办法不采取我们的首选。首先，Holley的狙击式电喷系统是一种TBI类型，设计用于螺栓连接到现有的进气歧管上。虽然这一特殊的套件安装在4150个化油器的地方，但版本可用于单管和双管应用。标准的四管化油器选项还包括一个双模式法兰，允许它螺栓取代方形4150或扩孔四管化油器。狙击手EFI的最大原因是我们的首选是简单的安装。虽然这比碳水化合物交换需要更多的时间，但它是你能找到的最接近的一种补充。它只依赖于四个电气连接，并使用了Holley的夹式氧气传感器，无需焊接。它也是一个自我学习系统，这意味着你不需要成为调优专家就能让它运行起来。你只需要遵循一个相当基本的程序后，连接一切，校准向导照顾其余的。不同的套件也可以缩短购物过程。 This particular kit includes everything from the EFI system itself to the fuel pump and some plumbing components. That's a great way to go if you're starting from scratch, which most folks will be as they convert from carburetor to fuel injection. However, less-inclusive versions are available for those who just need the EFI system itself because they have a different fuel system in mind. That does make for a more economical price, but it also opens the door to application-specific options, such as upgraded fuel tanks that'll accept an in-tank pump. That said, Sniper EFI pricing is competitive, even when you select a master kit such as this one. Each Sniper setup will support different power ranges, but this is capable of feeding engines turning out up to 650 horsepower. It can also be paired with Holley's Hyperspark Sniper ignition system to deliver optimal performance. Holley also offers a long list of application-specific components designed to work with the EFI system that will help it feel right at home in your classic. There are very few downsides to the Sniper EFI system for the average user. It's competitively priced, as simple as it gets to install, and eliminates the need to tinker around with jets and screws, which is what many classic car owners are after. However, there are some issues you should be aware of. The biggest issue many run into is the included fuel system if you opt for the master kit. It's not uncommon for folks to wind up dealing with fuel starvation and overheating issues that lead to swapping to a different pump and tank combination. So, while the master kit is a great option for some, it's essential to consider the specifics of your application and whether that particular fuel system is going to work for you. Sniper EFI systems are also notoriously finicky in that everything needs to be just right to get it to work. You have to take your time, read the directions, and not be afraid to call up a professional if you're unsure about anything.
