Product Details

This Stage 1 Water/Methanol injection system from Snow Performance is built around a 4150-style carburetor spacer plate, threaded for 1/8" injection nozzles. It's designed to help naturally aspirated V8 muscle cars run higher compression ratios, even on pump gas. By injecting a water/methanol mix, you can effectively increase your fuel's octane rating by 20-25 points, which allows for more aggressive tuning and cooler intake temperatures. This translates to more power and improved efficiency, all while helping to suppress detonation.

The system activates only when your engine is under full load, thanks to a Wide Open Throttle (WOT) switch. This ensures you're getting the benefits of water/methanol injection when you need it most, without affecting normal driving. The kit includes stainless steel braided lines with 4AN fittings for a durable and clean installation, along with a solenoid valve to prevent any unwanted siphoning when the system isn't active. You also get a 3-quart reservoir to hold your water/methanol mixture and two nozzles that can cover a wide range of horsepower applications. Everything you need for installation is included, along with comprehensive instructions to guide you through the process.

Using this system can allow you to run lower grades of gasoline while still achieving the performance gains associated with higher octane fuels. It's a solid option for modified V8 engines looking to extract more power and keep temperatures in check.
