Thank you Panic. I've made some headway in finding out about these blowers. The turbocharged 8v-71 and the 8v-92 both used the same blowers as the turbo made up any differences and a roots blower was needed only to start the engines. These blowers are 83% the size of a normal 8-71. I have ordered a 8v-92 from Deans Blowers with a reversed rotation so the inlet will be on the passengers side and outlet on the drivers where the intake ports are. I also spent some time researching chain couplers and lovejoy's. I decided against the chain coupler because of the RPM and harmonics. A lovejoy L225 with a Hytrel solid center spider. to this a sleeve to cover the spider and prevent it from escaping RPM will be added.
