If we’ve learned one thing while we were here for SEMA 2016 it’s that there are a lot of amazing builders out there producing some of the finest machines this little sphere we call Earth has to offer. We also learned that there are a lot of builders out there that are capable of making the C7 Corvette look even more badass than it already does—a feat we thought was damn near impossible. But when we stumbled across the Snow Performance Corvette we couldn’t pull our eyes away—mostly due to the eight (yes you heard that right) nitrous bottles in the rear hatch area.
Matt Snow is known throughout the automotive industry as one of the leading water/methanol experts and proprietor of some of the coolest kits on the market. We can also now safely say that his namesake adorns one of the coolest cars on the block.
You may recognize this particular ‘Vette since it has been making the rounds on social media—mostly because it is lugging around a spectacular amount of laughing gas in an area of the car that most Corvette owners reserve for their golf clubs on the way out to the course. However, we were no different than the rest of you, grinding to a halt in our tracks when we saw what this car was packing under the hood. As we passed the booth we couldn’t believe what we were seeing, so we stopped in to ask Matt just what this brute had to offer.
“The car showcases our new supercharger lid, that we will be offering soon, which is plumed for water/meth injection,” Matt said. “The car belongs to Mike Abney at NX, hence the nitrous, and he built this car for us for SEMA.”
Matt tells us the car was used to develop the lid that they will release in the first quarter of 2017 for any C7Z. The system uses eight individual nozzles, mounted directly in the supercharger’s lid, to cool the air charge after it passes through the stock intercooler system. This provides the LT4 with a dense, cool air charge packed with methanol that in turn also adds combustible fuel to the system and consequently horsepower.
So far the only modifications the car has received is a smaller supercharger pulley, that ups the boost by 2.5 pounds, and the water/meth kit. While that might not seem like a lot, it was enough to bring the car’s overall power output to 648 horsepower and 650 lb-ft of torque, with plenty more to be found once the nitrous system is up and running.
“With the methanol kit on the car we were able to increase the timing by four degrees, even with the added boost,” Matt said. “That was good for another 80 horsepower on top of everything else. The methanol cools the combustion chamber and allows us to keep the timing advanced, allowing the car to make much more power than it otherwise would.”
The conservative goal for now, according to Matt, is to spray the car with a 100 shot of nitrous. And while it might seem simple to just add 100 horse to the current output, it’s not quite as simple as it would seem. The water/meth system actually allows the car to be run with nearly the same timing as before the nitrous, meaning it will make substantially more than the advertised amount—or if it was just running nitrous alone. Not only does the methanol allow the car to retain its aggressive timing, it also cools the intake charge substantially—in some cases by as much as 50 degrees.
The methanol also will help supplement the limits of the LT4’s stock direct injection system by providing additional fuel when the car is pushed to the brink. However, Matt says that this car wasn’t designed to be a full-tilt build.
“It’s more of a subtle, rather than a radical, build,” Matt explained. “It’s just something that a normal guy could do, or would do, to his own car. You put a pulley on, you do a tune, you put this plate on so you don’t have to cut anything, since it’s a made-for-Z06 part, and you get a lot of power.”
This particular car is running Snow Performance’s Platinum system as well. In essence, it is a water/meth controller that can pull in many inputs and allows you to ramp in the water/meth delivery based on a tunable map that you, or the experts at Snow Performance, tune.
And while the car isn’t making record-breaking amounts of horsepower, one thing is for sure: Matt and the guys at Nitrous Express won’t be running out of giggle juice on this bad boy anytime soon.
