Cheap Supercharger

robertmagni · September 8, 2009

I see alot of used superchargers off of GM cars that are salvage and cheap. How hard would it be to hook one of these up to my 08 4.3 v6? what else would be needed? or would a used turbo be better what do you guys think?

A turbo and supercharger have different results, depends on where you want your power band.

I am not sure that anyone makes a blower for the 4.3L....

I have an idea about the answers to these questions between the two, but maybe some of you can help enlighten me (us):

- Power band onset (seems like it's pretty high for a turbo)?

- Noise (the superchargers I've heard were pretty loud)?

- Efficiency & power production?

- Longevity?

You can barely hear my supercharger until you put the hammer down. Then it's only slightly noisy.

If you do a turbo right, there's virtually no lag. Especially if you go twins.

Power production is rarely a problem with either.

Longevity? Who wants to live forever?

depends on the supercharger, there are 2 types....

...a centrifical which is like a turbo but ran via a belt and pulley and boost rises as rpms go up

...a roots style (positive displacement) which gets full boost down low but looses power, mostly due to heat, at higher rpms.

A turbo is most efficient, as it doesn't cost engine HP to run like a supercharger, but is a bit more complicated to install due the the extra exhaust pipe plumbing.

So it really depends on what purpose and where you want the power. A roots style is good for low end power/torque (good for towing) and a centri or turbo is good for higher rpm HP

so would it be possible to piece together a system from used parts? what all would you need to do it.

First off...how many miles on the motor?

4K easy miles

Cheap and forced induction are two things that do not go together. But if you must, the best deals are for used systems, but that comes with the risk of really not knowing how the system is going to be until its put on and run. On my 1995 Camaro I put on a ATI p600b supercharger that was brand new. It was on my car for several years and ran great. But I upgraded the cooling system, replaced the trans, and rebuilt the motor at about 114k miles (about 80k with the blower on it), as the FMU went bad and leaned out the motor and then cracking the #1 & #7 ringlands. So cheap to me is always a loaded question, because with power adders come extra cost to beef up or replace broken parts. Good luck.

gotta add bottom end beef to reliably have forced induction.. Then you have to address fuel(injectors, fuel pump, ect). Then you have to have the ecm tuned for whatever you install on the engine..

One other thing,, a turbo introduced a ton more of underhood heat unless you wrap everything or install the turbo's down stream..

Hate to say it, but if you want v-8 power,, buy something with a v-8.

He's right about the beefing....it will need to be done for sure. It might cost you more than swapping in a 6.0! Good rule of thumb is to take your current budget for the mods and double it. You will run into many minor roadblocks and all of them cost $$$.

On the good side you won't need a complete rebuild before it goes on.

I bought the truck really cheap, and it is easier to add some power adders than to replace an engine, not trying to get in Pinks all out just want some more power!
