OcUK Rolling Road 9: Photos + Graphs

Must have missed your car up on the rollers Darryn, I think thats when I ran off to get my egg and sausage roll :D Missed out on the vtec (y0) :p

Looking forward to the video, I couldn't stay in for too long because my ears felt like they were going to explode!
 
My Ears were saying 'Seriously.. GTFO now, its too noisy in here' But I stayed :D

I did have to put my fingers in my ears a few times though, The mustang though (you all buggered off to pub at this point) was mental, as soon as Nokin touched the pedal I had to plug my ears up, it was just insanely loud.

Thats why i left the room when i heard it going up in revs slightly :p

Great pics looks like people had fun

Powerstations "quote me happy" figures as usual though :rolleyes:

Funny how a couple of the cars that were totally standard were within 6 bhp and similar torque of manufacturers specs..
You get a couple of high readings on some others and all of a sudden everyone starting playing the "optimistic rollers" card.:mad:

I should also point out that my car consistently gets lower readings there than anywhere. And doesn't it get calibrated fairly frequently? There are RRs that read high, but that's not one of them (more's the pity...)

For those of you wondering what caused the traffic that caused all the breakdowns that caused all the traffic on the way back to the pub, this is what me and Fox passed on our way to the RR...

One C5, lightly grilled, with a side order of Caravan.
 
...imagine what would have happened if he had put that C5 on the RR ..and we moan about Rover's build quality and reliability. Could have been a Power Station Apocalypse!

I don't get it either they were not optimistic at all really, all the stock cars (bar mine) got 3-6bhp different readings, most high, some low. I think mine was the only one that read 'too high' but I'm going to look into that at some point, see if it does have any mods or not. :)

You only have to look at the quoted at the wheels figures and compare them to the fly figures to see they are a joke.

For example Mondeo ST220


Wheels - 156bhp
Flywheel - 241 bhp

Anyone can see those figures are a joke. A fwd car will not lose nearly 90bhp through the transmission lol!!


My integra roaded at 214bhp on powerstations maha rolling road

On surrey rolling roads dyno dynamics (Best rolling road about) it made 181bhp Which is more reasonable for an integra

Theres no way a dc2 teg will road 214bhp without major work i.e cams


Powerstations rolling road calculates drivetrain losses too high. The wheel figures are correct. The fly figures are way overinflated.

Using the mondeo as an example the rolling road is adding 60% to the wheel figure for drivetrain losses.

Drivetrain losses on a fwd car is meant to be about 15%

If you want to think the cars are putting out their quoted "quote me happy" figure then go ahead.

I'd happily show an st220 what an 181bhp integra would do to its 241bhp :o

Are you saying Moek's ST220 is making 180bhp at the fly then? As that is what 15% drivetrain loss would equate to.

Ohh and it has been said numerous times already this thread that the wheel figure is inaccurate due to how it is measured.
 
How can the wheel figure be inaccurate all a rolling road does is measure WHEEL POWER

If your saying the wheel figure is inaccuraste then you are saying powerstations rolling road is rubbish.

Thats all a rolling road does then it adds a percentage based on drivetrain loss and adds it to wheel figure to give the fly figure


Go ahead and believe powerstations rolling road if you wish, top tuners wont go near a maha rolling road because there not accurate you will find all the top tuners in the uk and america swear by dyno dynamics rolling roads.

Some people go on a dyno dynamics rolling road and come away unhappy because there 400bhp monster is only 350bhp. Truth hurts ;)
 
Oi, steady on now :o ..that's my ST220 you're aiming your lasers at. I have no doubt that an Integra would show me a clean pair of heels in a standing start drag race, it weighs a lot less (about 400kg less) than at ST220 and it has a short ratio gear box. I'm not so sure there would be much in it from a rolling start, from about 30mph though, I could be wrong, but once the ST's weight is moving and it's out of the torque limited 1st/2nd gear it can really shift, but that's beside the point.

If your figure of about 15% power loss from fly to wheels is correct for a front wheel drive vehicle, then if the ST220 had 'only' 220bhp, as it says on the tin (reality is, they all do seem to have more) it would still have 187bhp at the wheels.

And if you're wheel figures are correct, and I add 15% to 156.8bhp the rr says I have at the wheel, I would have only 180.32bhp ...I have driven enough other cars with power outputs in the 200-250 range to know that really isn't true.

Have a look on the net for how a rolling road works mate and what expected losses are for a fwd car.

Like i say if you want to think your st220 is 240bhp go ahead :)

Just never take it near a dyno dynamics rolling road because you will be gutted and walk away unhappy :)
 
Oh FFS, just leave the thread, seriously, I'm all for opinions, but to just constantly bash a company and say it's all completely wrong is not on.

Fine, you don't believe it, get over yourself and get out the thread.

What you are saying is EVERYONE is seriously under powered, which is bull, most people have hit stock or thereabouts with their standard cars, ST220s are KNOWN to get in excess of stock power even at standard. As for the modified ones, they've all seen pretty much what they were expecting too, so how you can say they are wrong I don't know.

And no, I don't want a high horse Dyno Dynamics rave about this post, we get it, you don't like Powerstation, move on. :rolleyes:
 
Heres another problem with maha rolling road and the incaccuray

S2000.jpg


Max attained rpm 9335


hmmmm thats interesting as the rev limiter on an s2000 is 9000 :confused:

Powerstation are a good company the fault lies with the maha rolling road and how it calculates losses.

Freedom of speech and all that dont drop the dummy
