UrS4 2.2T Avant project

[Thuppu]

~ 220km on track and 120 lliters of burnt fuel... was a funny day on track. We had our club trackday, and the car worked without issues. Will put up some more pics and vids soon...

My friends 510hp S2 on the left.

220km 120 litres of fuel?! WOW!

Nice car. How much oil?

[Thuppu]

Didn't have to fill up ones, so zero liters of oil. Front brake pads did totaly worn out though, only iron left anymore. Need also to change the discs.

Can you tell us more about the intake manifold on the UrS4? At this point, I don't understand the smaller "tube" on the outside side.

[Majorcina]

Can u tell me what size of IC u use since u still have stock bumper? Did u cut something on bumper or...?

Amazing that the hp2 works in the circuit. Bigger rear brake disc has an big impact?

I went to the track to have a look as I anyhow don't have a long trip. Met up with Thomas and he took me for a couple of laps There were a lot of nice Audis and some Porches. I didn't even bother looking at the couple of BMWs there. Also the ffp cup were there with a bunch of VW Golf MKII racing.
There were also a VW LT 45, an ex service car for Audi Sport in the 80's. It was more exciting than the Audi Coupe it was towing

Thanks Lars. You got much more pics than I. Yes, the HB Audi Team track car was funny, FWD and 4cyl engine with dual carburettors.

I have tried to do a dual plenum design manifold like the Audi sport have used for example on their LeMans cars. http://www.bufkinengineering.com/intake%20manifolds.htm

It's a 300x450x76mm core, and yes I had to cut the bumper some. I also moved the radiator 20mm more backwards.

I had no issues at all with the brakes. Only when the pads was gone they started to warm up and soften the pedal. But that doesn't mean the brakes are bad. Should have changed new pads earlier, but I wan't also to put new discs, so I will do a full overhaul now... I'll guess the calipers would need real heat resistant color.

Maybe the bigger rear discs help some, difficult to say..? But there is no problems with locking rear wheels like the old farts on quattroworld was claiming, and why almost no one from US hasn't bought adapters for the mod, lol.





The front tyres look funny

[Error404]

Haha, you got your money's worth out of those pads Thomas
You need more tyre pressure

[Thuppu]

Alex, I don't know..? Had 3,2bar, and who knows how much it increased when the tyre was warm..? Feels like too much, but maybe the tyre is just too loose for track use. Quite good grip though for cheap china tyres, and they didn't melt down.

And for next track day maybe we get a stiffer suspension...
