Was it cupraK1 who did that at one of the RR days(might have been surrey) when his 360Hp(AMD rollers) stage 2 cupra failed to get those figures on the DD rollers.   :grin:

no one makes good figures on DD rollers though, especially JKM.

CupraK1s car has made up to 379bhp on rollers that didnt belong to AMD, and around 360hp on other dynos aswell.

I had my stage 2+ done at AMD today pulled 334bhp thats stock intake, so if AMD rollers give out higher figures am i supposed to be worried now!

Im not!

But id say my figures are more "real" to what is expected form the mods i have? TB Miltek,HPFP, stock intake,stock intercooler...so with intake id see better side of 350bhp!?

thats why all the willy wavers dont like DD rollers.  doesnt make sense to me. better to say you have less(or more accurately) then its even worse for the car you beat.


there are quite a few cars on here that have made very good figures o DD rollers.  Gazbut abnd PDT to name a few.

dynoing a car in the first place is mostly willy waving though isnt it.

You sorta already know what figures you should be getting by the mods you have fitted so tbh its pointless other than being a sorta health checkup, but then again logging on the road is better still

Evey rolling road day I have carried out has been about the fun the banta and meeting up with keyboard mates. Rolling road days get spoiled when its about having the most power. If a car makes -20bhp then the dyno and OP gets blamed and takes a slating.

The only time a rolling road is good is when you use the same dyno to monitor you tuning power gains vs your stock graphs.

Apart from that its a "lottery" and should be just a bit of fun hearing your pride and joy banging of the rev limiter, and if your lucky you will get nice pop bang and a flame.

Two year back we tested all the dynos in our local area using our 210bhp mk4 Gti, and the results ranged from 195bhp upto 225bhp over four dynos, we found the biggest variation to be the transmission losses.
