Local club is doing a rolling road day, never been on the rollers before so just wondered if theres anything worth knowing first?
Do they put extra stress on the engine at all? I know they generally go up to the limiter in 4th (im guessing this is due to the 1:1 ratio of 4th?) Only ever hit the limiter a handfull of times and that was in 1st/2nd.

 

lol a rr virgin, you`ll **** yourself, its horrible

 

dont worry pal,, usually 6.5k rpm is where they stop although it sounds a lot more on the outside lol,,,, where you going??

 

Just remember your engine is built to quite happily hit the rev limiter in every gear with no ill effects! That's what it's there for, the limiter is the highest safe limit the engine can run at, probably with a safety margin built in.

It's hard to remember that when your car is having the nads ragged off it and is screaming inside a small workshop though! I always console myself with the knowledge that it gets far worse stick off me out on the road anyway :P

 

Make sure the engine is warm after a drive, just up to operating temps. Gearbox will be nice and warm too. Make sure all tyres are up to the same pressure as normal (amazing how many run with lower pressures).
Apart from that just make sure they blip throttle on the run down as in real life you`d not shut off after a blip but slow down in gear.


And as said your butt will be twitching, as no matter how many times and cars you have on rollers, your ALWAYS worried lol.

 

lol ive got one coming up myself, a club do, tbh i`m nervous not particularly because of i`m worried about the engine or anything but you will understand once youve done one

my old car

 

and 1 that every1 forgets make sure you,ve got plenty of fuel its no good going in there with 1/4 of a tank it will boil

 

Yeah, and make sure its the right fuel. No crappy super cheap Asda stuff lol.
Clean airfilter, is another often missed.

 

Never had a car RR'd, but when I was at college we put my mates car on the RR, I remember the instructor fella a week before telling him to make sure his tracking is bang on.. I guess its to stop the car trying jump off the rollers..

 

Nothing to it

LOL, cheers for that!
Altho iv seen all those vids before, which probs explains a lot.

 

On the rollers your car get no more stick than if on the road (maybe a little less).

Just make sure the following are looked at before hand.

Tyre pressure all OK
Wheel nuts are at the correct torque
Gearbox oil checked
Enough fuel (no less than 3/4 of a tank)
If after market fuel lines make sure they are tight.
The correct fuel is in the car.
Car is up to temps (RR op should do this on the rollers before a run anyway)

And general check over before hand.


Just enjoy it mate. Oh, forgot to add. Take a clean pair of pants with you as the noise will freak you out and your be worrying (most of the time over nothing)

A rolling road is a harsh environment!

 

Its a bit worrying when its on but like priviously said you will have pushed it more yourself on the open road before and who ever puts your car on the rolers would have put plenty of cars on there before and would stop the sesion if there is a problem.

 

when mine went on for the 1st time i walked out on warm up lol, but had to see it, the noise is incredible, watching the tvs showing the info on car is brilliant. i dont know about a rr day but i trusted jgm 100% when he mapped mine on rr.

as for guy doing a power run with little or no engine monitoring i dont know lol

unless they do monitor aswell as a mapper,and il stand corrected.

 

just don't do this

personally I love it on the rollers, you get to hear what the scoob really sounds like

 

Scaremongers!

Take a look at this one, well over 500 bhp and no drama at all.

 

yes, BUT not all rolling roads are equal, some oporators are complete muppets.

The most important issue (besides securing the car well obviously) is getting proper cooling to the car as there is no natural airflow that you would normally get on the road.

 

Boiling fuel????? Wtf????? Sorry guys but i have never heard this and i have had several maps/tweaks on rollers.

 

When I had my cossie on rolling road it was just a bit nerve racking to hear how much noise it makes in an enclosed space, no major dramas though

 

Me neither. The boiling point of petrol is approx 95*c. How petrol could reach this temperature in a vehicle pre combustion is beyond me.

who said boiling petrol?????

god knows but fuel tank by hot exhaust with no cooling - maybe????
