600bhp MRC S2

[Robatron]

I wouldn't call it nice - i would call it scarey.

I wasn't the fastest audi on the dyno yesterday - the RS4 beat me on the road (and smashed my windscreen) and had an extra 90bhp on top of me and loads more torque.

Charlie was very impressed with the results, I think they may have even made the 'wall of fame'.

By all accounts it's a very accurate rolling road too.

It produces some big numbers on the gt35r! It seems to surge quite alot though?

[Doug_RS2]

it does surge - strange how we don't hear or notice it as much on the road though.

how the hell did you manage to smash your windscreen??...

649!!!..thats the same power as 2.8217391 standard S2's...and 2.0603174 RS2's!!!...

(I know I am sad but hey.....)

[Doug_RS2]

the rs4 threw up something off the road and smashed my windscreen in 3 places.

Nice one Doug!

Glad to see that your S2 is back on the road. I had heard some rumors but its good to see that tis back in action.

That power output is most impressive too!!!

Well done.

SMASHED WINDSCREEN!!!!! Oh no, not again.

I remember the last one being replaced!!

@Doug, no need to thank me, I enjoyed doing it, didnt enjoy running it in tho, can i borrow it again now its mapped!?

You need to weigh it now, I may still be able to beat you BHP/ton. LMAO

Is that a stone chip destroying the windscreen or something else?

ETA: Just realised that you answered that question already!

Doh!

[audiman]

These garrets are a PITA for surge. But the surge isnt bad, and isnt there all the time.

Ballistic figures. Didn't realise GT35 was capable (still don't like mine though).
Nice to see both Doug and Tom posting. Be great to see you on here more often though.
Cheers

It is the gt35/40 with large hotside and it has a ported and polished hotside as well. If you want a car to be more drivable you need a smaller hotside and higher compression. I run 7.0:1. The power i have is not all through the turbo, mihnea managed to get the car to run 33 degrees of timing around 7-8k which will make the car much more efficient and produce power without silly boost. The egts are low so a good sign everything is efficient - surprisingly so at he power we are doing but you can see from the rollers that the manifold only goes red at the collector and not on the runners.

I was in Marks a few months ago and i think his a lot more drivebale - seems to kick lower down and harder.

We'll put more miles on it and then we will do a race fuel (109 octane) map and we will see what we can get out of it on pump fuel - tesco99. 700bhp on race fuel?

Doug: did you get the power/torque at the wheels numbers too?

(interested in seeing estimated drivetrain loss on the Dyno Dynamics)

[Doug_RS2]

520bhp at the wheels iirc

[Jamo]

Ballistic Missile! Did I read right 33 degrees of timing at 7-8k???????????

How the hell have you manage that!

[EspenW]

520bhp at the wheels iirc

Sounds about right (and awesome on the lowest reading dyno in existence )
