Ah, the AAN manifold looks more suited in some ways.

What I mean is... like, a hypothetical box that could contain an intake manifold without hitting anything important - hood, radiator, brake booster, stuff like that. Someone on grabcad actually did a model of the flange side, but it's not too useful to make a manifold that doesn't fit in the car, you know?

This is at least partially a... stretching my reach to improve my ability to design and make stuff, if you get what I mean, I appreciate your indulgence.

So, what I know has been done on some cars is rotating the Radiator to provide more clearance for the Intake Manifold:



This will let you clear a AAN intake manifold, of course you have other manifolds that are more forgiving of space:

Hmmm. Well, I'll try something, if it doesn't fit it'll at least look cool.

In other news, I put a chipped ECU in the 4kq 20vT, its running awesome but I've maxxed out the stock K24, so I'll put the RS2 turbo on it, but I'm getting binding in either the rear or center diff, likes its locked but the lockers are disengaged.

One of them may be damaged, and I suspect it might be the rear.

So what sort of power output are we talking about with the RS2 turbo + 2bar map?

I assume the drive line is sufficiently over-engineered to handle that?

Yes, Audi 016s and the rear diff/driveshaft will handle well over stock power.

With the RS2 components we can easily do ~300 HP

Peak HP for the RS2 setup is roughly 380.

Took the Audi to the shop to check suspension, need to do the strut mounts on the front, smoked the car and found my boost leak source: a 1 inch tear in the boot from the intercooler piping to the intake. Now it boosts like a demon again, spiking on the crappy Bosch boost/vacuum gauge all the way to 25 PSI.

Its good to be back.

Not that I know: Haldex is way past my prime, the furthest I go is Torsen or Locking Center Diff. I know the Haldex limits total power transfer to 50% to the rear and no more.

What sort of issues are you having? The shop I work at would be able to answer your question, they service Haldex regularly.

I swapped a V8 200 Hood onto my Wagon. I like it better, I need the matching lights for it, but it looks fine for now:

I think his video describes it. Front wheels spinning and rears not doing poo poo.

I have always heard that Haldex systems are garbage, but that's just like my opinion, man.

Are you doing this on jack stands? Because I don't think it'll lock up the controller on the rear diff if its setup like that.

Nevermind, they should spin. Find someone who has VAGCOM and see if you can check the Haldex controller's status.

quote:

How to Check if your 4Motion/Quattro is working:

This applies to the following cars: VW MKIV Golf R32, VW MKIV Golf V6 4Motion, Audi TT 225 Quattro, Audi A3 1.8t Quattro, Audi S3 1.8t Quattro, Skoda Octavia 4wd. This will also apply to other cars that use the Haldex 4 Wheel Drive system.



The following items can cause your Haldex All Wheel Drive to be not working. Double check all these. Some require the car to be lifted off the ground.

1: Fuse 31, 5amp
2: Earth on Differential
3: 0.7 amps of Power to the Controller
4: Brake Light Switch
5: Handbrake Switch
6: Haldex Oil and Filter
7: Differential Oil
8: ABS Sensors
9: ABS Master Control
10: Haldex Controller
11: Haldex PreCharge Pump
12: Differential


As you can see, theres a lot of factors involved with the 4motion working or not.

With Car on Ground:

Check the fuse first its the top middle fuse (large blade fuses) should be 5amps, if its higher then replace with 5amp blade fuse.

Connect up VAG-COM and using the measuring blocks you can see if certain things are working for the controller. Temps should be room temperature to start off with. The Power should be 0.7 watts or apps or volts, not sure but that figure which ever it is. Its been a while

Also, with vag-com, you can check the pump with output tests. This is better doing with the car off the ground.

Do a hard launch, if you get front wheel spin, then no power is being delivered to the rear

If you get a grinding noise, then the differential is at fault, where the pinion has moved and locked both the rear wheels.



With Car off Ground (All 4 wheels):

With vag-com, you can check the pump with output tests. This is better doing with the car off the ground.

Can you hear the pump/controller activate once you start the car? if not, then its the controller/precharge pump.

Check that the propellor shaft is moving. This way you can eliminate the front differential.

Start car, put it in 1st, then second like you normally do while driving and let the wheels spin, If all 4 wheels spin, then something is wrong with the differential/precharge pump. Not enough pressure/lock is being applied. This can also be the controller. With this, change the filter/oil for the haldex and the differential. This may solve the problem.

If just the fronts spin or 3 wheels spin, double check that the drive shafts are moving or not. If the prop shaft is moving and the driveshafts are moving but not the wheels, then your drive shaft is buggered.

I Want To Believe.
Based on the video in the snow, Haldex shouldn't be doing that. I don't know how much slip they have in the system at whatever the nominally full lockup front to rear is, but I'm going to say "not that much".

I agree it probably won't do anything if you have all four wheels in the air (so no speed/torque discrepancy), but lighting up the fronts like that should almost certainly make it engage the drive to the rear.

Edit: Just seen your post, CommieGIR - careful, that looks like genIV info, and his car will be genV without the precharging, unless I'm mistaken. I don't know if that affects how you can diagnose it jacked up.

It won't on old Quattros like the Gen 1 or Gen 2 (Torsen), Haldex I'm not so sure about.

One of these turbos is less Alt-Right than the others.

Working on a possible turbo upgrade for the 3B 4kq, want to possibly go with a Volvo K24-7400, which will let me keep my precious low end boost.

Replaced a brake light lens on the TDI that had a hole in it, and hauled the engine hoist over to the 200 parts car to prepare to remove the transmission.

You could probably look through it in a hex editor and figure out at least where some of the tables would be. I assume they'd be contiguous in ROM and look like your average load/rpm 3D table.

How many tables are there? I assume it's a Z80 or something because Germans love those, so you should be able to also chuck it through a disassembler and see what parts of it seem like an actual program and not line noise. Unfortunately a Z80 is not a fixed-length instruction set :(

The program you want is TunerPro http://tunerpro.net/

Doesn't look like they have any bin files for it, though, but you may be able to find some on the gargler. I used this the other day to get the stock ignition advance tables for an m20 to plug into my megasquirt as a baseline.
