I have plans of purchasing the 185 pulley this March with tax return. So as for now, have we definately concluded we need to keep the stock 90MM idler pully to keep the bearing RPM's safely under the max spin? Are there any other pulleys (other than super charger)with this 185 set up spinning any faster than the origional factory setup? With 35,000 miles I don't have any problems with purchasing a longer new belt. I realise it may still be in testing,but has anyone mached up the ultimate supercharger pulley to bring out the NeedsWings manifolds full performance potential? Thanks... Don
