UrS4 2.2T Avant project

[prj]

On a UrS4 I have tuned here on gasoline, with standard camshafts and standard head, no methanol injection and 98 RON, we got 350kw at the wheels with 2.3 bar boost to redline. Also HX40 Super.

350kw at the wheel and original head and camshafts are very good I think. What do you have for exhaust gas temperatures?

[Rocco]

490whp?

So flywheel must be like 580hp?

Peak is around 800C after turbo. After that the ECU floods it. The car runs 11.9 on 1/4 mile, which is not bad considering it's weight.
But it is not very fast on a long distance, because it floods to 10-10.5 AFR to prevent the engine from melting.

This season methanol injection and 7A camshafts will be installed, and we will see how it goes.

I had exactly same setup on my urS4 and it did 604hp/758Nm (flywheel). Boost was ~2.1bar.

11.4 1/4mile and 272kmh 1mile

And Thuppu, very promising start with that mild level of boost you got.

Quite difficult to tell real ex temps if it measures after the turbo. The sensor should be in the manifold collector or in the beginning of the turbo hot side. That is propably close to 1000C in the mani.

Testfitted the icewheels. Front fitted well with a 2mm clearance, but in the rear I had to grind off a bit of the calipers. Maybe soon it's time to drive on ice.

nice one thomas.....you must be thrilled at the results.....

Nice. I wish it was possible to do some ice racing here in Holland

[Laaf]

Do you plan on going to Tahkovuori 7.2-8.2?

[Thuppu]

Mike, I was really supriced about the output, and yes, it feels good.

Lars, no, I'm not going there. It's too far away. Nice to blow the engine and be stuck there.

I guess the Frankenstein engine will hold pretty much everything I'm keen on taking the S4 and go have a look on saturday, but I'm attending on that very friday. Guessing that driving for a couple of hours wouldnt be really fun then

New exhaust tip. 2x3,5"

Could not go bigger Tomas?
