i have to express some stress!! 
i have just learnt a valuble lesson today..
DO NOT ARGUE WITH A RETARD!!
to give you an idea...
Chris
everyone needs to know that it was not a whp readout but a calculated at the fly readout.. and to work out torque by letting the wheels slow down themselves.
so my 143bhp is not 143whp = 171.6bhp its just 143bhp calculated to flywheel, nice to meet who i met tho.
Stampy
The blokes said it was an at the wheel figure.
Some tidy pics there topless especially the one of mine on the rollers!
Chris
yea the bhp is measured using the wheels, but the power output isnt from the wheels, did you notice how he let it wind down, well thats what calculates the fly power.
Ste2k08
no its definaly at the wheel readings ..... !!!!! 100% sure of that
chris
how can it be a bhp at the wheels result when the standard vx220 2.2 is 145 AT THE FLYWHEEL and i got 143 when its TOTALLY standard!??
the guy was saying that it is measured FROM the wheels but the BHP was calculated as an at the FLYWHEEL result..
are you trying to tell me a standard corsa c 1.2, the silver one made 79 at the wheels?? that would mean its over 95 at the fly.. come on guys.
Lozza
the reading we was given was at the wheels so i believe, my vectra shows 208bhp at wheels standard and i got 202 so dont always beleive what the manufacture says as all r/r readings can be different as it depends on tyre pressure and ambient temperature at the time
chris
3.2 V6 Elite 5d 7.0 s 154 mph 208 bhp (more info)
3.2 V6 Elite 5d Auto 7.0 s 153 mph 208 bhp (more info)
3.2 V6 GSi 5d 7.0 s 154 mph 208 bhp (more info)
http://www.parkers.co.uk/cars/specs/Summary.aspx?model=964
these figures are at the fly.. not at the wheels, i dont think ppl understand that a reading at the wheels is different to a bhp result at the wheels.. you loose on average about 20% of power through your gearbox.
so your 3.2v6 being auto or not produces 208bhp at the FLY.. which would be about 166bhp at the wheels.
ste2k08
he definatly said to me the reading was AT THE WHEELS
chris
he said it was 'measured' at the wheels, as he said it to me aswell, but its impossible for the results to be shown at wheel bhp..
ste2k08
well thier is no way my sisters coupe is pushing 220 or less bhp .. when its meant to be 270 !! yeh its looseing abit of bost .. but not enough to make it loose 50bhp !!!
chris
look m8, im not argueing with you, im stating the bleeding obvious.. how can mine be at the fly correct, the corsa 1.2 at the fly correct and hers be wrong? what exactly has she done to make it 270 bhp?
ste2k08
Ok i asked shell my sister and she has been down befour and it is 100% at the wheel figure ... END OF STORY !!!
Chris, ring hi-tech and ask him and he will tell you its the BHP AT THE WHEELS, NOT CALCULATED FROM THE WHEELS, BUT THE BHP THE CAR HAD AT THE WHEELS
Hope that clears the air
chris
How can a car with 143bhp as standard which is 143bhp at the FLY get 143 at the wheels..
TELL ME HOW!
how can a standard 1.2 corsa get over 94bhp at the fly..
how can them astras be 395 at the wheels that means they would be 493 at the fly..
the cally turbo 220bhp.. that means again 275 at the fly
ive produced facts, i have produced numerous examples of why its at the fly, all you have done is said, so-enso said this so it must be true..
just sit back and think about what you are saying, sit back and look at how its measured..
and to top it off i get the email back from the guy who owned the RR'd said its measured at the wheels aswell..
is it jsut me or is this realy a wheel reading!

My god the fucking spoons 
The best, 'Ok i asked shell my sister and she has been down befour and it is 100% at the wheel figure ... END OF STORY !!!'
Yeah ok that bit of science clearly ends the story

its got to be this:
all chassis dynos (drive on dyno type) do measure the power at the wheels, theres no other way that they can measure power as opposed to:
hub dyno which measures power at the hubs, you remove the wheels and bolt the dyno unit to the hubs. It then gives 2 readings, power at the hubs and calculated power at the flywheel.
engine dyno which calculates power with the engine out of the car and measures the power at the flywheel, no gearbox etc... gives a true flywheel power.
Now when you take those facts into account there is no way that the chassis dyno you used could take real measurments from the fly, so the confusion that has arisen is due to the fact that the dyno used DOES measure the power at the wheels but it is likely that the computer then calculates the estimated flywheel power. So when you ask the dyno operator: "does your dyno measure the power at the wheels or the fly?" his only answer he can give is that its measured at the wheels, then its up to the operator to explain how they calculate the flywheel power and that the fly power is printed on the graph, which many dyno operators dont do because its a confusing process to explain it to people.
So their answer "it measures the power at the wheels" is 100% correct. what you need to ask them is "how do you calculate the flywheel power for the graphs?"
hope this helps.

Well summed up Dave! You can see how the 'uneducated' to the area could make the confusion.

yae dave i agree, but as i said about they have taken the measurement from the wheels, but then as the graph prints out etc, its worked out the fly bhp for you..
it doesnt stay at the 'at the wheels' bhp.

i just got this PM from the lad..
Hi chris,
Not to start an argument, but i am quight anoyed with the fact you are not listning to what i am TELLING you ... The figures from that rolling road day are AT THE WHEELS, not mesured from or callibrated from the wheels .. but the power at the wheels
If you do not want to belive this, ring MICK at hi-tech and he will tell you exactly that !!!!!
I have multiple examples that prove that its at the wheels .. IE my sisters coupe turbo, and the VXR astra has a stage 2 remap and exhaust and it mean to be pushing 280-290 break ... which is rite when u take 261 and add 30 for the loss of the gearbox
JUST BLODDY TAKE THE FACT ITS AT THE WHEELS !!!!!!!!!!!!!
And i was me deleteing your posts because you are giving people false pretenses about thier cars and its not on
Thanks
Ste

wait m8, ive had replies... they are hilarious. .
Ste2k08
i shouldent need to, if you ring mick at hi-tech and ask the question .. you will know then what ive been trying to bang into you from the start and quight frankly im fed up of saying it !!
I dont know why yours and mikeys were more than standerd, but like i have said i have 3 cars that prove that its read at the wheels ...
My sisters coupe turbo
Ment to be 270 bhp at the wheels ... was 255bhp at the wheels at hi-tech it wasent boosting at 20 but 16 .. which makes it right
The Astra VXR ... had a stange 2 re-map on it meant to be puching 280-290 at the fly ... meaning 261 reading at the wheels is about right when calculated to the fly ....
Most of the V6 vectra's were roughly about rite on the day to what they are meant to be read at the wheels ...
Just either explain to me why u cant be arsed to phone up and ask .. or why you wont accept what i am telling you ??
who organised the rolling road day ... me and my sis or you ??? i think we know what the BHP readings were ..
and dont forget the 2 mark 3 astras pushing well over 300bhp .. which they said was rite ... at the wheels !!!!!!!!
either drop it and accept its at the wheels .. or ring mick tuesday

What website is this?
Just direct them to this post, they've clearly been bambooseled with whatever words the RR operator has been throwing around. Its clear how these works & you cant ignore the fact all these standard cars are making what they should. His argument of a modded car should be making whatever is just pointless! MUG?

I just sent him this.
''The Astra VXR ... had a stange 2 re-map on it meant to be puching 280-290 at the fly ... meaning 261 reading at the wheels is about right when calculated to the fly ....''
lets do the math shall we.. (20% loss from gearbox ok?)
261 + 20% = 313.2bhp
or if you want to work it out the other way
261 / 80 * 100 = 326.25
so if its at the wheels.. your telling me the astra has over 310 at the fly..... i think you just proved yourself wrong.
\edit: the website is www.vauxonline.co.uk
if it makes a difference.. the lad is 18 and owns the site.
