yes some rollers can do this by converting the mechanical drag as per what sideways danny was on about afew posts above

thought id show you my results mate, i cant see how the traction control makes your torque rise and dip, mine being a ph1 doesnt have traction control and mine did the same, mine was also on a Dastek
mines standard apart from a cat back exhaust
141.6 @ the wheels
173.3 @ the fly
though the following run went up to 143 @ the wheels on the next run(box oil hotter lol)

They had turned the traction control off for all runs.
I was very impressed with the facility. Full of race tuned TVR's!
They did 3 runs:
Corrected power = 189.5 / 141.3 kw
Engine power = 187.8 BHP / 140.0 kw
Wheel power = 140.6 BHP / 104.9 kw
Max power at = 6510 rpm / 110.4 mph
Torque = 163.3 lb.ft
Torque seems quite a good result. How does it compare to the standard 182's?

I've PM'd Henk to ask if the torque figure is what he'd expect on an otherwise standard 182 just with the remap.got to love these "over" reading rollers
378bhp Leon Cupra R
But look where my torque crosses with the power on my graph it should cross at around 5K not at 6.25K
TVR Cerbera
Sorry, but that power graph is false.
The torque and hp curve HAVE to cross at 5252 rpm. FACT.

RB 182 cup
only if both torque and bhp use the same scale as bhp is a calculation of torque and rpm
TVR Cerbera
Only going on what i've been told by various tuners. looking at that graph you could be right as the scales are different, however with the torque all over the place poss due to traction control, why is the power line smooth if it's calculated from torque and rpm?
TVR Cerbera
looks similar to mine and other ive seen
182
i reckon on 166 at the fly for that car
if you have a look mate my bhp and torque do meet at 5252rpm, the reason why the graph shows they dont is the bhp reading on the left goes up to 170 bhp, and the torque readings onthe right only goes up to 150 lbts ft, making the graph look out of place, if you look at the indevidual graphs below you will see the bhp and torque do infact cross at 5252 rpm
see my above post, yours is the same, your bhp and torque do cross at the right time, its just the left side reads up to 190 bhp where as the oposite side reads to 155 lbs ft
TVR Cerbera
So your point is? the graph shown is false. If you have a power graph showing hp and torque, it will look odd if the scales aren't the same. And by the way i wasn't actually talking about your graph as you hijacked the thread, i was trying to help out the originator of the thread
sorry chap i think we are both getting the wrong end of the stick, are you saying mine or his graph is false? false as in made up?
most graphs are shown like this btw, with different scales
also you say if the scales are not the same it will look odd, this is why in my above post i said do not look at it as 1 graph, look at it as two seperate graphs on one page, that is why also i provided in my thread the bhp and torque graphs on seperate paper, so you can see them seperatly
nothing meant nasty chap, dont think im meaning anything personally, because you seem to be taking it to heart
I'd heard a 10 BHP gain was quite usual with RSTuner remap.got to love these "over" reading rollers
If my car was running at high 170's before it, could be the RR results are accurate.
as above matey flywheel power is always a guestimate, always go with wheel hp, for example as a rule of thumb fwd usually loose around 18% power through the drivetrain, if yours had that bhp and 140 at the wheels, thats alot more transmission loss than 18%,best thing is take it with a pinch of salt, the wheel bhp is not bad
B/G 182 + PH1 Track
10BHP at the pub maybe. Recon you would be lucky to see 5BHP increase with a RStuner kit (i have one so yeh)
BHP and torque figures are measured at peak ie the highest point before they tail off.
How can traction control have any effect at the top end of the rev range especially when they run the car in 4th :S ??
The guys at austec said the TC had to be off & I noticed they had turned it off before beginning the dyno runs.

I was saying his graph was false, cos i didn't look at yours. Not false as in made up, just enhananced
a little.I didn't look at your separate thread so wasn't passing comment on it.
I agree that different scales are used but should be kept to different graphs like you said to avoid confusion. if the graph shows hp and torque then i believe the same scale should be used

ah lol ok chap i understand what you mean, i do agree i wish they would be on seperate graphs, to be honest it confused the hell outta me the first time i studied my graphs until i saw the different scales on either side lol
378bhp Leon Cupra R
Well i emailed the graph to a guy i know thats involved with the tuning of the Clio cup racers and told him of the lights on my dash when i left.... and it was him that said the cross between the torque and power cross to late on the rev range and he said that the traction control had not been turned off which cause my loss in power at the wheels( eg much more than 18% lossed )
But if you look at your graph mate they dont cross at different points, they do on the graph because the bhp on the left measured higher than the torque on the right,i keep sayin it, imagine the graph as two different graphs on one piece of paper, it doesnt matter that they cross at higher revs because the scales they are measued on are different , bhp up to 190 odd, torque up to 170 odd
Monaro VXR/Cupra TDi
Agreed.
Mine made 149.4 ATW = 180.0 ATF. This was at RS Tuning. Pauls rollers are spot on, there isn't many others that are.
182
yep - pauls rollers 146 atw 177fly iirc
So if the RR shows 140 bhp atw (and from what people say that seems about right) then you can say 20% max loss atf which means a true engine bhp of 175.
26% transmission loss to generate the 189 bhp atf on a car that's been well looked after & has very low miles seems rather far fetched to me!

Cant be bothered to read all of the guff in here, but id say the tranny loss is way to high on the OPs graph. ATW figure is the only one that should take any interest in, Flywheels figures are only useful down the pub imho

so is your figure quoted in your profile at the wheels or the fly then
:rasp:couldnt agree more AT THE WHEELS ONLY PLEASE

TVR Cerbera
Here's my Dyno printout, atw, at Santa Pod last year. Was tuned at 233bhp at the fly so this looks quite acurate.....
