High-altitude pulley for NS Supercharger

[647mk4GTI8v]

Hi guys I just bought a mkIV GTI 2L 8v AEG. It is high mileage and plan to replace all the internals with oversized forged goods. I would like to supercharge the car and make atleast 250HP. Is the NS charger the only one that will fit this engine? What kind of power were you making on smaller pulley? My car will only be driven weekends from time to time so I do not mind some limitations if it gives more hp? I appreciate any help as I would like to be able AutoX, Track, and cruise occasionally.

It's doubtful you'll make 250 with the SC, especially since this SC does not have an easy way to intercool it. Also, max boost is around 12 psi with a 2.4" pulley and is way beyond the efficiency threshold. The SC takes about 25 hp to build 12 psi at 6500 rpm--that's a lot. There are some centrifugal chargers around that may work better for what you want. For that kind of HP, you should think about turboing it.

Subscribed. I am not sure if you have been in the thread I have started recently. I am still trying to figure out all the details to add a Lysholm to my ABA swapped mk2.

Just throwing it out there....I wanna buy a 2.6 Pulley if anyone has one lying around..

[unc1185]

Got a 2.4 instead Bye Bye VrWhat?

[supajut]

I have scoured this thread but cannot find out how much oil the supercharger takes on refill. Any help?

[unc1185]

This is " " from JettaRed, the creator of this thread who prob has most of the knowledge on this charger...

Magnuson would not sell me a maintenance kit, but did say I could get supercharger oil from my local Pontiac or GM dealer. The GM part number is #12345982.

Pg 100 I believe.. Altho It does not say how much, IMHO unless you have leaked, you should put around the same amount that comes out, maybe a little more its a tough call..

[McNeil]

Just talked to Magnuson on the phone and the tech guy said it should be just below 4oz. He said when filling it do not let the fluid leak out of the hole, fill it just below that level.

[supajut]

Thanks guys!!!!!!!!!!!!!

[Mr Roo]

figured I would ask. There is no way to adapt a NS supercharger to a 16v head? I like the one piece design and simplicity of the charger, but really like the flow of a 16v.

[andrewduffield23]

does any1 on here know how to get the inner snout bearing of the shaft so i can replace it

[advash]

WOW What a thread...

I have to admit I didn't read every post, seems like a lot of asking of the same Q and updates over the past few years of info... So I apologize for re asking Q but here goes

#1 As far as I can tell nothing needs to be done to the motor other than to install the system. Correct?
#2 I didn't really see any feedback on millage? not that I need TDI numbers but I also don't want to drop insane amounts. Does millage stay similar to stock?
#3 Anybody have a complete system for sale?
#4 I’m just looking for a little more pep, not trying to race every car I see on the road, Other than those who really want 300+ hp happy with their setup? I don’t want to end up with a maintenance nightmare either.

Thanks
Dave

1. The ECU needs to be upgraded with software to adjust timing and fueling. You may need to go with a 4 bar fuel pressure regulator if you decide to go with a smaller pulley. If possible, a boost gauge and an air/fuel gauge should be added.
2. Mileage stays close to stock, but your foot probably won't. Generally, if you increase horsepower, you need more fuel. And, with more hp, you have more aggressive driving.
3. Can't answer that one.
4. Well, the SC will give you noticeable performance improvement. And once bitten, you're infected--there's no cure!

[andrewduffield23]

Well I have a question for someone.. does anyone know how to get ahold of the guy that got the intercooler set up made.. ide like to work something out with him

[JettaRed]

The guy's user name was joeZX6. If you search, he hasn't posted in over seven years, so you may have a hard time reaching him.

Hey jettared i was unable to see the pics of your wmi setup im doing that real soon and also did you end up running a nozzle before and after the charger?

[shane_kid88]

hi i have a mk3 2.0 obd2 aba golf 260 cam, headers, bored throttle body, cold air, stage 3 clutch, recently put mk4 supercharger kit on and i have problems, if i hold throttle steady between 2 and 3000rpms engine misses and goes up and down, as soon as you give it the little extra it will free rev no problem, running 2.6 inch pulley and 1.9td 5 speed trans long gears, first 3 gears work good 4th and 5th buck and go on like crazy, new plugs wires cap, rotor button, tryed different coils, mafs, tryed stock ecu tune and my cam tune and the neuspeed tune all have same low end miss which i never had before car worked great for over a year. im lost running the plugs that came with kit

[_moose_]

Im running a ns charger on my 05.5. It have variable timming on it. Wase able to make the whole set pu work but still want more power. my charge will sit at 5 psi all the way through my rpm band. I start picking boost at 2500 rpm once I passed 3000 it pins 5 psi. I already have the high altitude pulley with the p-flow chip and intake. I'd like to put a solid timing head on but I don't even know if it's possible, haven't done any internal work like a cam or anything but still wondering if that would even be plausible on the fact with variable timing head. if anyone has some info on how to help me out of the really cool for now peace out.

[andrewduffield23]

bumping an old thread again but, anyone ever try throwing one on a 16v head by making a custom intake mani ?

[jlee7]

is there any way i can throw this on a BBW engine?

[eurican]

I guess I can throw this up. I recently had the car on the dyno this weekend to see what the numbers were since the last time I was there. Since the last time the changes are: EIP BVH, 30 lbs injectors, Brospeed header, C2 software, P&P lower manifold, and the cam gear set to -2

specs?? Those numbers are pretty good

[eurican]

What do you mean by specs....I listed what I have done in the previous post. I also have the 2.6" pulley, TT exhaust, 256 cam, swiss cheesed airbox...

Specs of the car. cam? exhaust? pulley size? W/M? cold air/ram air/swiss cheese. But you already answered those lol

I figured I would join this never ending forum by saying that I picked up a Used Neuspeed charger about two weeks ago. I installed it on my 95 Jetta and am happy with the results. I believe it has a 2.6 inch Pulley since i hit a solid 9psi at redline and almost 4psi right off. The only thing i noticed was an Increased vibration at 4000rpm, not sure if its due to the supercharger or the new engine mounts. When the charger was installed i took a peak at the oil and the charger rotated nicely, but I was in too much of a hurry to enjoy it. I ordered the maintenance kit but it had not come in at the time of the install. My current setup is;


272 TT cam and valve springs
Techtonics high flow valves (slightly bigger then stock, have to look up the size again)
Mild Port and Polish
Header
2 1/4 TT Cat back exhaust with magnflow muffler
Vr6 Cat
TT adjustable cam gear set at zero.
Neuspeed Supercharger kit (2.6 pulley i think)
K&N drop in filter
Insulated intake gasket from BFI
BFI .5 motor mounts
R32 control arm bushings
80% O2O shim kit
Neuspeed front and rear sway bars, front strut tower brace and soft sport springs.
Converted to OBD II (wiring harness issue when I first had the car!!!!)


Now I just need a better clutch, when i hit 9psi in 3rd,4th and 5th the stock clutch slips! So If any of you know of a good cheap clutch, let me know. Otherwise has anyone else running a 272 cam with this charger? I originally picked it up when the car was running NA with an AEG intake manifold.

[eurican]

How do you like the .5 mounts? I am looking into picking up a set for my car.

[corrado9184]

I like them so far,i have very little vibration below 4000, above that I get a noticeable vibration. Dont know whats causing it. Maybe the charger, I am not sure but the engine does not jump around like it use to. My wife does not like them or the sport springs.

[OMGitsKYLE!]

this has prolly been covered but those of you running the 2.6" pulley did u get a smaller belt too?

[greyhare]

I ran the 2.6 on the standard belt without issue.

[Fast VW]

I ran a 2.4 on the "stock" belt without any issues. The MKIIIs have the advantage of the automatic tensioner. I currently have a shorter belt on but I have noticed no difference.

[eurican]

How do you like the 2.4" pulley? What other mods do you have with it?

[Fast VW]

The 2.4 pulley is pretty cool.

I have:
1. 2.4 pulley
2. AT270 cam
3. Autotech catback SS exhaust (the old single tip design)
4. C2 motorsports 30# injectors and tune
5. Stage 3 Snow Performance MAX-MPG water injection kit
6. Lower temp thermstat and fan switch
7. Vibratechnics motor mounts

Here it is:

[corrado9184]

update... I had my supercharger off the other day and measured the pulley and found the size stamped in it. Impossible to see while it was on the car, I have a 2.8 inch stock pulley. So I am looking for a 2.6 or 2.4 inch pulley for a reasonable price.

[DriveVW4Life]

I ran into this thread while surfing the forum, researching a turbo project I'm doing.
I had a Neuspeed charger several years back. Tons of fun!
