I have a 91 Century with a 3.3L and i want to supercharge it and am not sure what brand or size, i know there are not any kits for this particular vehicle, and i wish to at least get a supercharger and build it up. anyways i am not sure if i should upgrade the fuel and ignition. i know i need to only run around 4 PSI or less. to keep it from blowing up. any help on brands would be nice. thank you

Forget a supercharger. As far as I know there aren't any supercharger kits for this particular vehicle or engine. You may be able to get a turbo but that is doubtful too.

i know there are no kits, thats why im asking about what brand to get, and if i need to upgrade the fuel or ignition, besides if i wanted to do something weird i would turbo it, wouldnt be hard, but i want a small supercharger

Unfortunately, there aren't any superchargers available to fit this particular car. The engine isn't made to handle it and it would take a great deal of fabrication to even try to fit one to the engine. The Superchargers on E-bay are junk. Not the Eatons or roots style but the ones that look like a fan motor don't work so don't waste your time or money.

but 4 PSI wont blow the engine, i am wondering about what brand of a centrifigul supercharger would be best, and if i needed to upgrade the fuel/ignition

The engine in your car is externally similar to the 3800, but isn't designed to take any mods. If you put even a small blower on it, it will be just that, an engine blower. You will smoke the lower end bearings and grenade the engine. If you really have to have a supercharger, you might be albe to swap in a supercharged 3800 from a 92-94 Park Ave Ultra or Bonneville iwth a bunch of fabricaiton, but you will need a complete donor car that includes the PCM/ECM, wiring harness, motor mounts, etc... The resulting car isn't worth the expense and time it will take.

Your all wrong there is a "super charger" made for a 1995 Buick Century 3.1L find it here http://www.superchargerswarehouse.com/ granted its a electric super charger that only pushes 2.5 to 3 psi but it does work I have it on my 1995 Buick Century. Its been on there for almost 3 years no without any problems. Also if you're looking for internal performance parts for a 3.1L (Cam ect) look here http://www.mantapart.com/2831v6.html you can also find a Throttle Body Spacer by Stillen here http://www.stillen.com/product.asp?id=EVETBS01&c=PE&m=all many of the parts available for a 1995 Pontiac Grand Am/ Grand Prix fit on Buicks. And if you're looking for a Cold Air intake you can find it here http://www.streetbeatcustoms.com/Performance/Air-Intakes/Performance-Intake-Kit/17796/

I love it when people talk about things they have no idea about :sarcasm1:

:confused:

That isn't a supercharger. Just a worthless gimmick. :screwy:

Rather than the air blower shown in the link, it would be better to run a duct from your AC blower to the intake! :rofl:

Good one Bo! :thumbsup:

I guess then you can call it a cold air intake (CAI).

HAS YOUR BLOWER BEEN BEAT?
by the guy down the street?
with Nitrus under his seat?

Funny he references parts for a 3100 when the OP was asking about supercharging a 3.3 V6. (two completly different motors).

As Rich stated, the 3.3 is very similar to the 3.8, but I am not sure if many parts could interchange. Would the LIM's be swapable? What vehicles were the Eaton M62's used in?

Blackrosetiger,

You state "I love it when people talk about things they have no idea about", and yet everything you listed is for a 3.1L which is a 60-degree GM V-6 where the OP's car is a 3.3L which is based on the 3.8L's 90-degree V-6. So nothing you rambled on about would even fit the OP's car, as these engines share no parts, other than maybe an oil filter...:rofl:

Lastly, do you even know how a supercharger boosts performance? Obvioulsy not, or you wouldn't have bought that POS fan you put on your car and actually believe it's doing anything.

Hi, I've got a 2000 Buick Century in great shape. So, is their no true supercharger for the 3.1 GM v6? The tranny is quite weak in this year. Was rebuilt by GM at 35000. How much gain can you get grom one of these "electric blower deals"?. Would it be best for me to just by a later model Regal GS with blower? THanks

I placed this reply somewhere else also. ThX

Paxton?

An electric supper charger just cant be large enough to do more than 5 HP Max at the bottom end and almost nothing at high RPM. That is not enough to get a seat of the pants feel out of the darn thing. The current draw would be so high you would have to have an alternator and electric motor the size of the engine to power the blower. Pumping air is a taxing endeavor at best. In a top fuel drag car, the Hp requirement to run the blower is around 750 HP. For that 3.1 you are still talking about a hefty 15-30 Hp at 5000 RPM.
(Ever see a 15 HP 12 volt electric motor? It is the size of your car engine)

I still don’t know why you don’t opt for an engine swap.

There is no replacement for displacement.

How are your shade tree engineering skills? You can stick a Paxton on just about anything if you can build your own “kit”. You could under drive the Paxton LS (Little Shit) By the time you finish with that, your are looking at $4K

But!

Has your blower been beat by the guy down the street with nitrous under his seat? I know that the belt noise is kinda cool at first but it does get on your nerves after a while. A $400 35-75 Hp NOS bump kit will make you go “Holley Christina”

Would it be best for me to just by a later model Regal GS with blower? THanks

Yes. :grinyes:

If you do anything with those old GM V6's its like throwing money in the trash. You would get the same hp tq result if you just bought a 2nd generation 3800 powered W-body. Which is alot more refined than the old body styles. And for cheap too I've seen decent intrigues impalas regals grand prixs for under 2500.
