How different is it running an auto on a rolling road?

 

My brother tried to run his granada cossie on Engine Advantages rollers but couldn't get an accurate reading and was told that you won't ever get a proper reading something to do with the car always changing up.

 

why cant u lock it in 3rd or something, do they not usually have that option or does it still change up?

you cant get at at the flywheel figure i dont think,, but you should have no problem with an at the wheel figure

 

i put a v8 lexus on the rollers at power engineering and they said the figure will read higher than it actualy was due to the torque converter. the car showed just shy of 300bhp which is about 20 higher than o.e spec.

 

run it up in top gear....


make sure you can knock it from drive to netural easily thou, its a nightmare if it jumps the rollers and you can wack it in neutral!

Other than that it like any othere car!!

Cheers Alex!

 

do you run it in sports mode btw?

150mph in top on the rollers in an Omega LOL

 

dont think it makes a difference to power output. just holds the revs longer.
