I bet he was, here the graph, lets see Don pull that apart

The torque curve looks a bit iffy.

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

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.
