Rolling Road session 6th Feb 2005 Well Lane Turbos

[volvotuning]

In what way mate ?


What should it look like ?

All T5s (even with RICA) should start producing the max torque of about 420 Nm from around 3500 rpm and hold it to around 5500 rpm. This one, along with many others, seems down on low and mid range torque. Yet the car is quicker in the mid range (timed) on the road than stock, therefore it must have more torque! Go figure.

Should be atleast 240 lbft @ 2100rpm rising to around 315 at 3500 rpm and holding that till about 6k.
Im not sure but thats what I would imagine would be about right.

I know mine feels a lot more torque than standard as she will pull from 35mph in 5th without hesitation, standard she wouldnt do that!

Well i think we all know why the plots are not as they should be, but lets just wait and see when you have your own installed Adam, ill be first on the list.


Cue Duane.......

lol glad to see i have a use

1 = J
2 = Pedro (depending on the date)

I have a theory, and it is just a theory since I wasn't there...

If everyone's torque was much lower than it should have been until the higher rpm, then it's possible that the dyno was not loading the cars up until the higher rpm. This mean that the cars may have simply been spinning up the rollers with zero or little load applied until a predetermined rpm set by the operator, and only then would the eddy current retarder start to load up the cars, hence only then would the cars start producing the correct torque figures.

It's just a theory, but it's definately possible since it does depend on how the operator sets up the rolling road.

Still, a good day it seems and everyone had fun!

Any chance i can be 3 please!


Yeah the operator was sometimes loading it as he often was in neutrol

3 = Lance

[GuyD5]

Number 4 please Pedro

[Wobbly Dave]

I should like to see if better operation could improve my 264bhp. So book me up for no 5. Plus I agree with Hamish the fan seemed very small and badly positioned

[JackT5]

Well i finally made it to a meet up if only as a spectator and enjoyed putting faces to names, even if it was bl**dy cold and had to leave before seeing all the runs. Cheers guys for an interesting and informative morning out.

Sound like it was better for some than others but that’s Dyno days for ya

Dave if you want to get the real figures out your motor, book it in for a 1 on 1 session and allow most of a day to ensure you have plenty of time for half a dozen runs and plenty of cool down time.

Most will charge around £150 - £200 for a full days running but it the only way to get the TRUE figures out your car

2nd actually (ladies first see!)

So it seems the RICA is a bit crap then. Those results are very disapointing, esspecially as a standard car can mix it with the rica boys and girls......


now where did i put that number for upsolute !!

One car did manage the 310 bhp, i was expecting 270-290bhp out of my car due to worn turbo so 266bhp wasnt to bad , + the fan was small ,and I dont think the tourque measurments were accurate in any way.
I dont think rolling roads give autos a true reading,
Hamishs car was in a kind of limp home mode on the rollers with all them ABS lights on and doors open which isnt supprising of newer generation computer controlled vehicles.
The standard 850 was in good order,low miles and had the horns relocated and dirty air filter removed which belive it or not helped it gain over stock bhp.
There was only one vehicle with under 100k and a lot of ex police vehicles ,Im, sure and know mine wasnt the only vehicle with running issues.

[Mrsmopp]

I am reserving all judgement until I get on VT's rollers.............

[Bracer]

The only other Dyno I would use is Adam's.

But I still wouldn't expect him to come up with the goods within a 20 min time slot for my car.

[monsterdark]

Well I was pleasantly surprised with the output from mine 155,0000+miles & produced 238 BHP for a v70 me7, book says 240 & auto standard apart from exhaust & air cone so I seem happy. Nice to put some names to faces hope to see you all again soon
Cheers Steve

1 = J
2 = Pedro (depending on the date)
3 = Lance
4 = Guy (& Pammy i assume)
5 = Dave850R

[Andrew]

Go on then stick me down too

[Wobbly Dave]

I am a little bothered as both myself and Andrew seemed to get relatively low figures both on almost identical cars.

I too await the install at VT with baited breath and reserve judgement on the figures until people I really trust have had a go.
