Building a plug-in hybrid sleeper can be a smart move if you want both efficiency and a comfy spot to camp out in your vehicle. It lets you run quietly and skip the gas station for a while, which is pretty handy for overnight stays. This setup appeals to folks who want electric power for…

When you modify your engine, keeping it cool becomes way more important. Heat soak happens when your engine and intake parts soak up too much heat, which drags down performance and can actually cause damage over time. The best way to prevent heat soak is to improve cooling through better airflow, quality radiators, and heat…

Electric vehicle batteries really thrive when kept cool—think somewhere between 20°C and 25°C. Sticking to this temperature range with the right cooling mods can stretch out your battery’s life and keep your EV running like it should. Cooling mods can be as simple as a few fans or as involved as a full liquid cooling…

Performance tires and wheels can cut your electric vehicle’s driving range by bumping up rolling resistance. Basically, your EV has to work harder to move, so you don’t get as many miles per charge. Switching to performance tires or bigger wheels? You’ll probably see a 5-8% drop in range, depending on the size and design.…

When you modify a vehicle, keeping a detailed logbook of all changes is smart. A well-kept mod logbook gives clear proof of what was done, making your vehicle more appealing to future buyers.

Your schedule should focus on regular checks and services tailored to your car’s modifications and driving style. You’ll need to…

When someone mentions a “built engine,” you’ll probably get a different answer every time. Generally, a built engine means it’s been upgraded or modified beyond what the factory made—usually for more strength, performance, or just to keep it alive under tougher use. This usually means swapping out or beefing up things like pistons, rods, or…

Variable Valve Timing (VVT) is a technology that changes when engine valves open and close. This adjustment helps improve your engine’s power and fuel efficiency across different driving conditions. By altering valve timing, VVT allows your engine to perform better at both low and high speeds, giving you more torque and saving fuel. When the…

When you start modifying your car, it’s easy to get swept up and want to change everything all at once. But honestly, the biggest thing is not making changes that wreck your car’s reliability, safety, or get you in trouble with the law. A lot of common mods can actually cause headaches if you don’t…

Piston coatings matter more than you might think when it comes to how your engine handles heat and friction. These coatings work as thermal barriers and friction reducers, letting pistons run cooler and slide with less effort. That translates to stronger performance, a longer-lasting engine, and sometimes even a little boost in fuel economy. You…

Getting insurance for a modified car can feel like a headache, but it doesn’t have to break the bank. The smartest move is finding an insurance company that actually gets modified vehicles and values your upgrades fairly. Be upfront about every change you’ve made, and get your car properly appraised. That honesty pays off down…

Regenerative braking helps you squeeze more miles out of your electric vehicle by grabbing some of the energy that would otherwise just disappear as heat. If you want to boost regenerative braking efficiency, try slowing down gradually and coasting early—gentle braking beats slamming on the brakes every time. This approach gives your car a better…

Building a high-compression engine can really boost your car’s power and efficiency. But, honestly, it’s not all sunshine—there are some big challenges to watch out for. High compression means the engine squeezes the air-fuel mixture much more than usual. That can crank up horsepower, sure, but it also raises the risk of engine damage if…

Building a budget-friendly home dyno can sound intimidating, but you can actually make a simple setup with stuff like scrap steel, an old electric motor, and some basic car parts. A basic home dyno measures engine power by putting a controlled load on your engine and capturing data with cheap tools, so you can tune…

Starting out as a new tuner means you’ve got to know more than just how to adjust strings or settings. There’s a whole legal side you can’t ignore if you want to dodge expensive headaches. A lot of new tuners slip up on the legal stuff—ignoring product safety rules or signing contracts they don’t really…
