Hey guys,

I'm very happy to announce that our supercharger kit for the 2014 5.3L Direct Injection Silverado and Sierra is ready to ship. We're taking orders this week, and we'll be shipping the first 20 or so kits before the holidays (they make great stocking stuffers). Pricing and kit info available here on our website:
Silverado Sierra 2014 5.3L Direct Injection Radix Supercharger - Magnuson Products, LLC

We're really happy with how this kit turned out. The Direct Injection motors seem to love boost, and the driveability is spot-on. We made 416 HP and 444 lb-ft at the wheels, a 105 hp and 105 lb-ft increase, on our EO tune and 6.5 psi. We've been driving our development truck back and forth 100 miles to meetings, and when we can keep our foot out of it we get 24 mpg.

An added bonus of Direct Injection is that it's a quicker install (no injectors or fuel rail to change). We did our last install in under 4 hours, and that's with taking pictures and coffee breaks.

Here's a picture of the kit, and of our development truck. Plan on ordering new rear tires...





Feel free to reach out here, or by email at sales [at] magnusonproduct [dot] com if you have any questions. The 2014 6.2L DI kit is coming as well - trucks were backordered so we're just getting ours here on the west coast this week.

Do you have a picture of the blower with the manifold sitting on a table? Curious to what the lower manifold looks like. Does your kit provide any modifcations to the fuel system?

 

We'll be posting more detailed pics of the kit in the coming weeks on our site. To answer your question about the fuel system - the fuel system on the 5.3L trucks are set up for e85, so both the fuel system and the injectors have lots of head room. No fuel-system changes are required.
