Magnuson is the first company to offer a supercharger kit for General Motors’ new line of full-size pickups equipped with the 5.3 liter EcoTec V8 engine. The company needed a way to demonstrate just how much performance a blower adds to the new pickup, so naturally, they lined up a bone stock 2014 Chevrolet Silverado alongside a Magnuson supercharged model on a runway for a drag race.
According to Magnuson, their new MP1900 TVS Supercharger Kit helps the 5.3-liter V8 produce 416 horsepower and 430 lb-ft of torque. Despite the large gains in power, the fuel economy isn’t entirely diminished with the kit. It features an Intergreated Bypass Valve which allows air to escape before it enters the supercharger, so it won’t produce boost unless driving under heavy loads, helping to deliver stock-like fuel economy and driving characteristics when cruising around at low speeds.
To see how much performance the kit really produces, they tasked the two trucks with towing a 4,500 lb Jeep on a flatbed trailer. They then lined the two up side by side for a drag race, were sure you can figure out how these tests turned out, but what matters here is by  just how much the supercharged Silverado beat the bone stock version. Scroll below and watch the video to find out.

So then it’s 5 hp behind the 6.2….. I wonder what the horsepower will be if they supercharged that 6.2 liter
Not only is it down 5 hp but its down 30 ft lbs to the 6.2 which is important for a truck. I’d rather the 6.2 you get more hp torque and equal or better fuel efficiency, but like Vic I too would love to see a supercharged 6.2
If I heard correctly the Magnuson guy stated it made the horsepower and torque numbers at the wheels. I will only take that as speculation since he showed nothing to prove the numbers. However if those numbers are true, the SC’d 5.3 will still be out in front of the 6.2 in stock guise.
That’s right – the numbers we mention in the video are rear-wheel, measured on our Mustang chassis dyno (which typically reads lower than a DynoJet). It put down 416 rwhp and 444 rwtq. If you use a conservative 15% driveline loss, that’s about 490 hp at the crank. It’s a gain of about 110hp, and puts the truck at about 70 hp over the 6.2L L86 (but we think GM underrates the L86 – it’s probably more like 40-50 hp over the L86.
it is funny that the bone stock 5.3 has bigger and heavier aftermarket mud tires on it. well known to rob power from a bone stock truck doesnt look like they comparing apples to apples guess that comparison showed the supercharger was a waist of money hmmmmm
I was thinking the same thing.
True story. The bigger tires would have robbed some horsepower, but not anywhere near enough to close the several car-lengths the supercharged truck pulled on the stocker. This was just for fun, and to give you a sense for how much faster the truck is with the supercharger. We’ll post real quarter mile times soon when we can get out to Fontana.
maybe i was a little harsh. i can see you guys were making a quick informative video. i do believe a super charger would be more fun.
I gotta get one of these 4 my 2014 Silverado!!!! I’ve already added dual exhaust & I am waiting to 4 my K & N cold air filter system 2 come this Thursday! But I’m thinking Super Charger all day right now!!!! How much Matt & when are they gonna be available?!?!?!?!?!
Hi Lyon – these kits are available now, and the retail price is $5960 through any of our dealers.

I have a 2014 silverado ltz crew cab fully loaded,20 inch custom wheels, blue topaz with all the chrome, its the baddest stock truck on the road, we can go at it all day long about aftermarket upgrades but naturally aspirated bone stock its tough&fast, here is the true stock specs for all 2014 trucks(highest motor&trans packages available stock/no turbo or supercharger) 2014 6.2 silverado/gmc sierra =420 hp /460 torque,2014 ford f150/raptor6.2=411hp/434torque,2014dodge ram hemi 5.7= 385 hp/407torque,2014 toyota tundra=381hp/401torque, 2014 nissan titan=317hp/385torque Also the silverado/sierra has better fuel economy At the end of the day its chevy, ford, dodge, toyota, the nissan
I’d like to see a list of your dealers please.
