I think we all can agree that a stage 2+ golf r running a 13.4@107 is a bit funky...
In contrast I have time slips of other stage 2+ APR golf Rs running low 12s.
Hard to say what exactly happened, isn't it Al?
I have heard about DSG cars doing good times with various flavours of software. Never seen a time slip yet though or a spec sheet of the car right enough.
I guess it is hard to know what happened too - although not having a car at the moment, I don't much care as most standard cars are passing me on my trusty Trek
All Brand A, B or C aside though, the sharper tools in the box will know the plot and area under the graph is more important than the peak numbers and if the logs show the plot comes without the expense of bad things happening in the engine, like timing pull etc, then you are on to a winner especially if it drives nicely and performs better than most.
Regarding that specific Golf and its dyno numbers, it does actually pose a valid question re the dyno run. Forgetting about the whole APR/Revo thing, what I would like to know is how a car driving the 2 front wheels can have lower calculated flywheel hp figures from approx 20 hp higher wheel hp figures than another car driving the 2 front wheels when it would normally drive 4 wheels - both cars back to back on the same dyno on the same day. Cars in question - Leon Cupra R and Golf R both with the CDL engine with similar modifications bar code.
Presumably, with the handbrake disconnected on the Golf, the prop, rear diff, drive shafts, Haldex and rear wheels not doing anything means the calculated losses of a 4 wheel drive car no longer apply and the flywheel hp should have been calculated as a 2 wheel drive car and not a 4 wheel drive car? The basic gearbox is the same on the 4 wheel drive and 2 wheel drive cars as I recall - I know Dan still has his original gearbox despite driving 4 wheels on his Leon instead of driving only the 2 front wheels as it was before.
Fair play if I am mis-guided/wrong/stupid but this is still puzzling me.
