Ramee's Tiguan Build Thread 155KW DSG

[tigger73]

Some data logs of intake air temperatures with stock and S3 intercoolers installed. They logged in nearly similar times of different days with ambient temperatures nearly same on same path from my work to home. Logs show a very clear decrease in intake temps with S3 intercooler even though it is not an ideal intercooler, still heat soak little bit at traffic lights.

Nice work Ramee. Always good to have the hard facts to support spending the time and $.

Today I changed the Tig's rear sway bar with a Whiteline 24mm Heavy duty sway bar. Whiteline sway bar is a solid bar compared to stock hollow one so considerably heavier. Whiteline one comes with two stiffness settings and I first installed it in low stiffness position. During the test drive I could feel considerable improvement in handling even with mild setting and body roll is fairly under control, but you can feel it is still there. There are some favourite spots where I can really see the handling improvement of the Tig such as long curvy downhill road sections and I can safely say there is a significant improvement in body roll.

Some pictures of the install.

Stock vs Whiteline sway bar


New sway bar installed. I had to use M10 and M6 XZN bits for the operation.


I did not have XZN bits in my tool box so had to buy some. Supercheap and local Bunnings did not have them, Total Tools have them as a set with other mixture of bits.

Surprised you didn't go for the stiffest setting first

Oh! You know me well then hahaha .. But I felt I may need adjustable end links for stiffer setting. But not sure? Do you have them?

When you go full stiff, keep in mind who might be driving the car as some vehicles can get a bit tail-happy, especially in the wet.

It's not a bad idea if you go full-stiff to get out on a wet day and go around a full sweeper or a cloverleaf with ESP off & doing about 7/10ths & accelerating & back off the throttle suddenly to see if you get snap-oversteer.

On my Liberty on full-stiff it was fairly easy to invoke oversteer when I had it on full-stiff. You didn't get caught out if you were concentrating but it would catch you if your mind was elsewhere or if somebody was driving that wasn't aware of the handling charateristics. The mid-setting was totally forgiving & the ride was nicer as well as the firmer the setting, the more "coupled" you are making the independant suspension - which kind-of defeats the purpose of IRS.

Yes I will keep the sway bar in current setting ( mid stiffness ) as I am quite happy with it. Still when I go over road humps ( speed breakers) if only one rear wheel goes over the bump I clearly feel the hardness of the sway bar compared to stock one. Stock sway bar is fairly forgiving and allow for more wheel articulation to absorb the impact, while with WLSB one it feels bit rough and a vibration.

I hates speed humps... Some are so unbelievably harsh it isn't funny...

Yes MGV you need better shocks hahahahaa

I've found some of these "traffic calming devices" can turn a boring side streets into a slalom course I'm sure it's not how the original designers intended but it can be a bit of fun.

Also regarding some speed hump designs you can (if you get it right) take them at reasonable speed if you get the weight transfer happening in your car right and can actually be smoother than slowing right down.... I mean what is your suspension for right???

Yeah! One of my mates who hate big SUVs (including mine even though it is not big) asked me why these so called SUVs always go very slowly on speed bumps, aren't they supposed to go off-road and can not even handle a small road hump at reasonable speed?? haha
