tbh your right!! But i can't see why GMC would put this on their site, if its bollocks! its not as if they are ebay sellers is it!? they must have tried and tested this, otherwise they will be offering a service which "doesn't work" and get themelves a bad reputation! im sure the owner of GMC is a member on here, perhaps we should invite him to answer and give him a chance to explain!!

i know its gmc doing it but i thinks its just another money making pointless mod really

i believe mankee did test one on a RR with his s1 rallye 16v.

noticed an improvement but he didnt keep it.

some one pm,ed me and asked me to comment on the posts--when i stop laughing at the lack of physics knowledge --i might .
yes it works -- of course an alternator takes power to make electrical power --,no it does not totally disconnect the alternator thats why the power streering keeps going --it allows enough current to pass to stop any damage to alternaotr controller (1/2amp)- no battery won,t go flat cos it has safety circuits which will not allow it to work if battery violtage is too low .
I know of no std car that does this.--please tell me which car it is--exact model please
power saved will depend on state of battery charge of car at time and total elctrical load required by car at time of operation --so it works better at night on a cold wet day as you will heated rear screen ,fan blower ,wiprers and of course your big ice amp taking power.
proven to work on SAC dyno -- saving up to 11bhp on my xantia diesel -with all electrics turned on,uusual saving will be closer to 4-5 bhp at most times--it is called fre pwr because it frees up normally lost power when you want it most --on acceleration.
as for comment about you can turn aan alternaotr by hane --that is because when you do not "excite the field coils you have no magnetic field --please refer to text book on how and alternator works .
if it didn,t wotk --why is one of the things that is always written in race regs for modifed sallons --charging system must work --cos it saves power by not having one
