Real world performance comparison

[20Vcqdriver]

Have the CGR 6 speed but with the wheel tyre combo of the series 2 57mph is the max. Still better than the 52mph that was possible with the standard Cq gearbox. 30-70 in 3rd last year with my mild 250bhp upgrade and small boost leak was 6.1secs.
Hopefully Paul's new chip and new hoses + charge cooler will improve things when it comes back on the road 1st May.

Anyone tried using the VAG-COM acceleration tests to produce these numbers?

The digital speed reporting is fairly accurate when compared with GPS and certainly much better than the analogue speedo.

I tried this lunchtime but got an interesting value of 3.6 (+-2.43s) what ever that means See below: -

So it could have been 1.2s then

Even better on the return trip (slightly downhill rather than slightly uphill): -

Does that mean I could do it in 0.3 secs?

0.27s

Peculiar. What size tires and what is the rev limiter at?

The B5 S4 boys use VAGCOM to log the so called FATS times.
4200-6500rpm in 3rd gear:

That translates to roughly 60-90mph

I think 60-90mph in 3rd is the best performance indicator. Would be interesting if some of ya'll good folks had some 60-90mph times to share.

[HPmuirt]

So no one knows what the numbers mean in VAG-COM then?

This is an interesting graph to study, the red line is my standard B5 RS4 and the black is my 450bhp ur quattro.

Cant believe the difference in the 0-100 no wonder the ur sh!ts me up.....

The beauty of power to weight combined with short gearing.

30-60 looks like 2.5s in 1st then 2nd, can you do a 30-60 in 2nd?

You've got rollout on there too, no use for road testing, you can see there is about a 0.5s error. Rollout is for drag racing...

The B5 RS4 looks like 0-100 in 14s, my S2 is just over 13, what's up there?

Come on all you VAG-COM experts out there. Someone must know what the acceleration numbers mean.

For the 60-90MPH 3rd test, VAG-COM reports 6.2 +- 2.44s so if we ignore what the +- means then 6.2 id faily good compared with the sub 300BHP S4's in the MRC table

Through 3500rpm to 7000rpm in 3rd is pretty real world although the speeds aren't. Second or third gear give the most realistic representation of performance for road driving.

IIRC yours is in the 270 to 280bhp region with strong torque? Not sure what mine is, will have to do a run and check...

[GazzaG60]

well i have ordered a gtech pro RR. i never seem to be able to make time to visit a rolling road so thought id get one.

any tips for setup etc for when it arrives.

[Rusty]

Read the instructions? Not got one myself but make sure you understand all the assumptions that they make.
