Superchargers

[kyhunting]

With all the used and rebuilt superchargers on the market (ebay) it looks like someone would have been daring enough to come up with a kit (brackets, tubes, ect) to bolt onto our 3.X engines. Nothing outrageous, maybe just 40-50 safe hp...

Just a thought for you Senior members.

Already been done by Superchargers of Knoxville, among others. All the ones I've seen haven't been reliable enough on the track.

I was referring to a crossover from a used production unit. Seems there are alot of units taken from production V6's and 4 cylinders. There seems to be alot of them on the market. I heard that the Knoxville Supercharger was no longer in business. Also, I wasn't considering them for track use. Just a thought for the junkyard engineers among us.

been there, done that.
I bought a supercharger, an Albrex unit for the 207hp 3.2L, is supposed to deliver 370-380 hp. Unfortunately the kit was not complete and i don't have the time to sort it.
Now it's just collecting dust.
Have you thought of all the extras that is needed, plumming, fuel, ignition, intercooler aso.
I see yours is a '87 so you'll have the G50 in that case you dont worry about gearbox.
If you buy a too small supercharger it will choke your engine when its sucking more air than the charger can deliver.
There seems to have been a British team that was running 964's with supercharger.

There's an article in Jan 2007 Total 911 about turbo vs supercharger - both on 964s. They do mention it can be fitted to earlier cars. Ninemeister Technic Kompressor Konversion

palle7688,
What is missing from your kit? Just wondering.

intercooler, plumming from charger to cooler and to AFM, 7th fuel injector or other way to provide more fuel, chip. Blowoff valve is also needed I guess.
I'm also missing some info about general installation.
I got the rear engine mount with bracket for charger and belt tensioner, got the belt and tensioner, drive pulley, a fuel rail, chain cover with a welded on stud for oil drain, hoses for oil in and out. There's also some rods probably to support IC.
If anybody have info about Albrex superchargers I'll welcome it in a PM.
Better stop before we hijack his thread, but thanks for asking.

Check this out for the Albrex supercharger. It appears that there is a kit or parts to put this on a 964/993. Doesn't give a lot of info but show pictures of some Porsche installs.Albrex

I run a Paxton unit on my 3.2 that boosts hp to around 350. So far the only problem I've had is a belt slip while racing a vette. That was my fault. the right side bulb on the tach was burned out, rendering the tach useless (couldn't read it) and I think I over rev-ed it which caused the belt to slip. It is a SOK type set-up, but with a v-belt drive. I plan to upgrade to the serpentine belt to eliminate this problem. Thats only happened the one time, but now some smuck in a vette things he beat the p-car. I guess it could have been worse, it could have been an m3 or some other inferior car.

Sweet, vettes are awesome and M3s are inferior...

[Larry_Ratcliff]

I think that super chargers are nice but with all the turbo accessories available for a porsche why not turbo charge?

[Mr Beau]

I've never seen a good write up on a SoK installation and subsequent testing. Has anyone seen one???

Did you install it yourself? Please give me some details. I have searched and can only find supercharge kits for the newer cars.

Thanks...

What's the chance that this could be made to work on a 87 3.2?

It's from a 1997 Boxster.

[palle7688]

everything is possible, a supercharger for boxster has the correct size to work with the "old" 3.2. But do have in mind your compression ratio. The 207 hp 3.2 can accept more boost than the high c/p 231 hp.

[palle7688]

Diamond, thanks. I know their hompage, there's next to nothing about the older 3.2L superchargers. Very stylish page though.

[Rodsrsr]

The Paxton unit is self contained so no oil lines are needed. I fabricated all of the ducting and the mounts. I did have templates from an old SOK kit. Fuel reg, and chip is all you need once you fab up a drive system. The SOK kits were very well designed, as I pretty much just copied theirs. I have been running it for about a year now with no significant problems. Simplicity, and cost vs benefit is the primary reason I chose SC over a turbo set-up.

[palle7688]

In my case I already have the drive system via a toothed belt and tensioner. It's basicly a beltdriven turbo.
Why haven't somebody made a charger that was belt and exhaust gas driven????????
Belt driven to give instant boost and ok, tap some ponies, but when it comes to drive the charger at higher speed you have the exhaust gases to help for free.
Just an idea.

[kyhunting]

Check this out. It's a TPC from a 993.
I know nothing about the 993 engine.
What is the difference in 993 and the 3.2?
Or should I ask is there anything that is the same?
As far as the block and mounting locations?

I am considering these guys for a supercharger. I know it's not exactly what you're asking for, but maybe it can point you in the right direction. You will note that the intercooler is an option, so not something you need necessarily.

I am considering a sc over a turbo because I don't want to mess with the already tight exhaust setup and I would like a more linear throttle response. Turbos are the proven setup, but there are racing teams out there that use superchargers for certain events and tracks as they lend to that application. I believe that applies well to street use and DEs as my limited skills can't put all that peak hp to it's best use.
