Rolling road tips

There are ways to cheat on a rolling road to get higher figures. 
R26
Dont expect it to make 182. It will be around 170-175.
Ask the operator to run it in 3rd, fiddle about with the RR to fudge the figures maybe.
As said, dont be surprised if it pulls about 170-175bhp though.

Addz - yeah mate id love for mine to make the '182' but i know its doubtful lol !
Plummer - what would these cheats be ?
A couple to start off, I would advise against them but they work!
On the day replace the air box filter with them ice/cool blocks you can get in the super markets (leave them in the freezer over night), will add a few bhp on the figures.
Another is to pump your tyres to about 40-45psi (I saw someone do it to 50psi!) this will add several bhp to the figure..
Some people do it to have the faster car, and others as they don't want their car under achieving.
I have never used these methods myself, I know others who have though!
(mainly VW owners!)

Change your oil just before you go, will give you a much better reading
It sort of shows how pointless rolling road figures can be, doesn't it !
Pumping up the tyres and running in a lower gear will increase the meaningless "at the wheels" figure. If the run down is done correctly though, these should be should be cancelled out.
Some good pointers on how to prepare, what to expect and what can effect the readings can be found here: http://www.emeraldm3d.com/em_r_road.html (scroll down to 'How rolling roads work'

Just put your car onto the rollers as it is, the bhp reading you get means nothing tbh. My car ran 167.8 and i've played with other clios running 185 bhp and theres been nothing in it even though we were running the same modifications with similar stripped out cars!
The only really good thing I find is that they can tell you what your AFR and inlet temperatures are across the rev range which I find more important.

ha ha, i like that!
I've seen 3 make 197-200.

It's much like fat people breathing in as much as they can when having their waist measured...... You get the result you want but it's far from accurate!!!!

Lucky RR session?
The same session had 172's making 165ish and 182's making 175-180.

Interesting. I would have thought that they would follow the same pattern as the 1*2s.

No two cars are built the same.
Some make book, most dont.
Theres honestly far too many circumstances to put a real figure to it imo
Temperature,tyre pressure,engine age,engine quality etc so on and so forth.
My fairly standard 106 GTi ran 133bhp on what left the factory with an apparent 120bhp, 2 other GTi's ran simillar figures...

I have been up against some rapid 106 Gtis. Stripped out, cams done etc running over 150bhp. Doesn't seem to take a lot to make them quick.

Yeah they seem to respond well compared to simillar mods on a F4R engine for some reason.../
The story goes that Peugeot (when testing) the GTi for insurance purposes i.e 0-60 times and what not were done with 4 people aboard and a full tank of petrol to keep the insurance group down...!
Seemingly for younger drivers so they could afford to insure them without too much drama.
Whether this is actually true or not is very much open to debate lol
It's a widely known fact that 106 gtis respond very well to breathing modifications.

Aye true matey, nippy wee cars.
The fact they weigh the same as an empty shoe box also favours the BHP/Ton

RR runs are like measuring your c**k - classic!!
The results are weather dependent.
The measurement usually produces disappointment.
Those who partake easily succumb to adverts promising enhancement.
The French are prone to exagerate in this area.
But of course, what really matters is what you do with it!

Just stick it on the rolling road no point in trying to artificially inflate the figures. If you really want to do something then give it a service.

remove the filter from the airbox lol, super unleaded, octane booster!
(this isnt why my old car ran big power as standard, it was just a natural!!)

Can you remember what alans R27 ran the last time i'm sure it was 198 one year the next it was 197, he was disappointed iirc.
