What's a good place to buy a used supercharger?

More specifically one for a Vortech 5.3 liter V8 in the 2008 GMC sierra. I want to keep my truck completely stock looking and just be able to scare the shit out of people with a monster of an engine! However with only 290HP and 350 ft/lb of torque I think it needs some encuragement. Also do you know if you can put a supercharger on a stock vortech V8? What else do you need to supercharge an engine? Do you need to do an ECU tune?

You will definitely need a ECU tune for any kind of charger. also whipple charger

Supercharger kits from Lingenfelter would be a good thing to look into I believe:

In a big truck that’s not much at all.

Are you serious?

Uh, a tune is required . Hell, plan for a few dyno sessions. No mail order tune for you!

Some other stuff:

1.) What kind of blower? Do you have the clearance to mount it?

2.) Fuel system? What can your current fuel pump handle? Injectors? Plan on replacing both of those.

3.) Intake? What can it flow? If you can get fuel, can you get air?

4.) What are the limitations of your stock short block?

My recommendation?

Spray it.

Joking, but not really.

Most engines will accept forced induction, with the understanding that boost is minimal. In order to get higher levels of boost, the engine needs to be set up for it. Although some engines are overbuilt from the factory and can accept higher levels. For example the Toyota 4.7L V8 was available in many different vehicles. However, only the Land Cruiser variant had forged internals. As a result, when the TRD supercharged designed for the Land Cruiser was put on a Tundra with cast piston rods, they would bend. Same basic engine, same supercharger, but one could handle it and one could not.

If you’re going to increase power, you need to make sure that the rest of the powertrain and cooling system are up to the task as well. No point in putting that supercharger on if it’s going to overheat or blow your transmission.

Not a lot, but should be sufficient.

GM 3.8L is similar.

Whipple makes a kit, as does protech. IT depends on your goals. We had the protech one because the centrifugal charger had less parasitic drag at freeway speeds and a stronger mid/high range punch.

Kinja'd!!!

Plus we could get an intercooler.

Most kits will have either a 9th injector or new injectors plus a pickyback ecu with a new tune.

That having been said, the 5.3 has great NA tuning potential. New cams and an ecu tune go a long way.

If you are looking for budget building it, turbo is the way to go. Though you might have to a little more work if your truck is equipped with AFM.

You will absolutely need a tune. The stock internals should be able to stand up, as long as you don't go too crazy. If you want to keep it stock looking, do an STS turbo instead.

OP says he wants to be able to scare the shit out of people, though.

If he wants to scare people, he hires me to paint the truck.
