Vortech Supercharger
February 18th, 2008 • Related • Filed Under
The Vortech supercharging system for the 4.8/ 5.3/6.0 GM light truck will impress you with the obvious attention to detail and fully integrated appearance. Increase your horsepower to 391 and torque to 420 ft/lbs (5.3 Engines) to help you pull you, your passengers and your toys over the hill or around the corner.

Nice! but proud of them
Comment by mikeith on 20 February 2008:
is that on the older 5.3 or the new one… the newer trucks has more hp/tq than the older 5.3’s
Comment by Vaquero on 20 February 2008:
are these for the 07+?
Comment by GMnChevy on 20 February 2008:
no, the newer engines have a different intake cover. And they make like 315hp N/A (without supercharger). so if you added a supercharger to the nbs engines, it should make at least 400+hp.

how does a 4L60e hold up to these numbers
Comment by Thomas990 on 21 February 2008:
how much does it cost and what other mods are needed
Comment by new08silverado on 28 February 2008:
what kind of hp should it increase on a new silverado with a 6.0??
Comment by GMnChevy on 29 February 2008:
on their site I read from 300 to 415hp… but I thought they have like 340hp stock?? idk, thats what the site said. and 360lb/ft to 447.

the new 5.3’s only put down 295 at the crank. I heard it’s only like 240 to the wheels

I doubt the 4L60E would hold up to that much HP One would have to have a serious overhaul on the tranny to get tha to last. I have an 06 Classic and the HP rating stock is 315…

My Friends 2005 Chevrolet Silverado 5.3L 2WD 3.42 Put Down 251Hp/293FTLB At The Rear Wheels Bone Stock. After installing the vortec supercharger like a year ago he jumped up to 368Hp, And 417FTLB. Man does that thing run!

I heard you should never supercharge anything with more then 100k on the motor? Your thoughts?
Comment by SPYGUY on 10 April 2008:
I dont know where you guys are getting your information, but here is the specs of the 5.3V8 on the 07/08 models..
“Engine, , Vortec 5.3L V8 SFI, with Active Fuel Management (315 hp [234.9 kW] @ 5200 rpm, 338 lb-ft of torque [456.3 N-m] @ 4400 rpm), iron block (LY5)”
This shows 215hp with 338 lbs of torque. This means with the supercharger you should be able to reach at least 400hp.

I have a Vortech Supercharger on a ‘97 Mustang Cobra (305 HP Stock), and the blower took it to 437 HP. No problems, and the power is great. Go directly to Vortech’s website for info. You can Google it if you can’t find it. The kit for the Cobra was around $3,800.00.
As for supercharging a tired old motor, use common sense and realize that it will definately stress internal engine components, so I would not do a tired old motor. Also, stufflike overdrive pulleys etc., will have to go. The little whitling noise that a blown car makes is cool, since motorheads will recognize it, and know your car/truck is something special.

out here in AZ I have a couple of buddys that have their trucks outfitted with vortech superchargers. John Melvin, owner of JM custom concepts from laveen AZ has a 03 black silverado SS that so far is the fastest SS in the country, running 11.22@120mph! makes about 633rwhp. His truck is in the vortech catalog. His partners in crime, Scott and Kevin Bartling of Bartling Motorsports out of Queen Creek run a pick up using E85 and runs 12.50’s at 115! “Ethyl” as its called makes about 500rwhp and is in the votech catalog as well. Quite impressive stuff!!! Got me thinking if I keep my 06 siverado I might look into a supercharger.

Thats alot of power for a 5.3. I wonder how the trans would hold up.
Comment by Red Pepper on 18 June 2008:
I have a 98 with the 5.7. I have a supper 44 flowmaster exhaust and a cold air K&N intake. The engine only has about 40K on it. Do they make a super charger for the 5.7? What modifications would i have to make if they make one?
