3.0 paxton supercharger info

[angelny911]

Hi I bought this kit from another pelican S.O.K kit with a paxton supercharger for a 3.0 motor just trying to figure out what else is needed and if it needs a relief gate or waste gate .I see one the cap that goes on throttle body has a vent pipe coming out of the side just want to know what gets attached to it ...they gave me some info on one guy doc who made the kit get any other info other than this 4 page booklet and he mentioned another guy mike in Kentucky ...but I haven't been able other info I know not too many of these survived because then came the 3.2 kits and help would be appreciated

A waste gate is for turbochargers, it controls the speed of the turbo by diverting excess exhaust away from the turbocharger.

I think a bypass or "blow-off" valve is what you are looking for. This is vacuum operated, so when you close the throttle, it opens and allows pressurized air to be vented to atmostphere (blow-off valve) or be redirected to the intake tract between the filter air box and supercharger inlet. This valve prevents the engine from surging/jolting.

The easiest way to tune is to size your pulley for the maximum compressor speed you want to run, there are compressor maps and custom sized pulleys available online, but since this was a "kit" it should be figured out for you.

SOK made two units. One was the centrifugal Paxton and the other was the roots whipple type. The Paxton kit did not use any type of blow-off valve.

Here are the plumbing that came with it .if you look on one of them there's a vent pipe sticking out want to know does in get attached to vent of oil tank ...

[Robbbyg]

That is nice!!
Looks Retro , i wonder how they compare performance wise against a k27?

The vent pipe goes here:



That feeds metered air to the aux air regulator and aux air valve in the CIS. It helps the car at cold start.

If you need a manual, I can send to you. Send me a PM with your email.

Thanks for any info or help the second picture is the one I'm talking about ...if you look on the top pipe you'll see on right side a vent pipe ..thanks. Angelny911at aol.com

LMFT4U...

Thanks for the fix JJ 911 SC. It looked normal in my tablet. Anyway..,

AngelNY911 the pipe in your picture next to the MSD replaces the elbow I am pointing at. The large round component of that same part replaces the rubber hat that the elbow is connected to in my pic.

They always do but the fix is to open them, rotate 360 degrees and save them, then post.

I'm following your thread as I got a 3.2 SOK kit that sooner are later will be installed.

I like the idea of these kits. maybe someday...gotta get a motor first though

[Dr J]

JJ. Do it. The supercharger definitely wakes these motors up. Particularly the 3.2.

AngelNY911 I sent you an email.

thanks to all replies

anyone know of adding an intercooler to this setup to cool incoming air ..see a couple of inexpensive unit on e-bay

[Mick_D]

If you have the room under the decklid it's probably a good idea. I think methanol/water injection is a good idea too.

[Rodsrsr]

Intercooler with a Paxton unit is counter-productive. That unit will only put out around 6 maybe 7 psi max, so with an intercooler, even a very small one you will end up with 3-4. What needs a cooler is the unit itself. It is self contained using only Ford type F transmission fluid to cool it. There is a small cooler that requires an electric pump to run the fluid through the cooler. If you plan on driving a lot this is mandatory. Without the oil cooler, the unit will get extremely hot and I have seen some seize up due to overheating. This is one of the drawbacks of a self contained unit. You also have to change the fluid on a regular basis. The oil cooler is very effective though. The company below bought the Paxton SN2000 line. He repairs them and sells the oil cooler kit.

Use a water-to-air. Flow very well while being in a very small package.

Drawback is extra weight and plumbing over an air-to-air unit and additional cost.

[angelny911]

Rodsrsr. I have a unit with oil cooler and pump so then I'm fine ...just thought if air was cooler going lower temps

Although some may disagree, I have had my setup for 15years. I have spoken to Paxton folks and SOK folks and both say that an intercooler is a waste of money and will not help with the Low boost of the Paxton sc. the whipper is a different animal. No cooler needed for the Paxton. I have been advised to use the oil cooler for the Paxton to extend it life between rebuilds.
