80q b4 2.2 20vt project

Hmm, I'm not sure. 33 teeth spline, propably 75mm if you mean bearing size..?

[M2ki]

75 or 82mm?

Seems that the shaft itself was ok, but the outer joint was broken.

Yesturday we had West Coast Street Cup 1/4 mile challenge here locally. The car hold up for 4 launches.



Quite long time since last 1/4 mile dragrace and different car than last time so it was a little bit difficult to get a good launch. Was also nervous of what will break. 60ft times was very poor 2.145s, 2.308 and the best 2,053 which also gave the best total 12,415s. Some guy from the audience told that it was just spinning the wheels to the 60ft marker, so no suprice the times was so bad.. Even tried to warm up the wheels a bit with small burnout before the launch. Good thing is the 01A gearbox did take the abuse, it held up. But in the last launch left rear driveshaft snapped so had to end it there.

Would easily manage to get 11.xxx times with it if the traction would be better.

Stock engine with I-beam rods and 7A cams. 5462 comp turbo with .48 hot side. 3" exhaust and Vems ecu.

The engine clearances are on the bigger side so it can be that there is little extra blowby, but compared to other audi builds(on youtube) the vapor amount doesn't seem to be so strange.. Not very many have the breather outlet in a visible place like that.

Yes it makes a nice driving car having a power graph like that. Similar graph to my urs4 with efr6758

Do you have dynosheet with this turbo?

[david1980]

Whats the final spec of the engine and what management if you don't mind me asking?

Also quite a lot of vapor out the breather system is that normal?

Very nice Thomas, to me it looks perfect for an aggressive road car.
Now then, 1/4 mile with 600nm will surely be the final straw for the 01A

Filip, yea, next weekend 1/4 mile drag race. Also Botniaring audifinns track day is planned if the car is fine.

Des, boost tapers down quite a lot, keeps the curve flat. The extra torque is nice compared to previous result.

[diesel des]

Very nice flat power curve

Looking good any plans of going any circuit driving or drag?

To keep the promise of destroying the 01A() I had some dyno mapping today. Car worked fine without any faults or issues, but the 500hp level seem to be hard for this small a/r .48 turbine housing. Best result was 496hp, but it was on the knock limit so the tuner reduced the timing a bit. Safe result is 488hp/621Nm.

[Henkjan]

Now just waiting to break the 01A
