Like many people I have my subscription to street machine, and someone wrote in and asked what does 6/71 ment, they replied with 71 cubic inches per cyclinders and the 6 is for how many cyclinders. I asked dad and he said the 6 was for P.S.I, whats going on? can anyone help me? Oh and what do people mean when they say "Earths"
Thanks

Hi Liam.W.

Streetmachine was correct. The number 6/71 doesn't actually refer to the supercharger, it refers to the GM Truck engine it was fitted to.

That particular engine had 6 cylinders & each cylinder was 67 ci in capacity.

It can't be 6 PSI because the PSI (pressure) depends on RPM & the amount the supercharger drive is geared to.

Should that be 71ci Dr Terry?

These superchargers were originally fitted to G.M. (Detroit) diesals as they are 2 stroke. The supercharger fitted for scavenging of the cylinders.

FastEh should know all about these.

Unfortunately yes...we have them in APC's and ASLAV's. 6/53 and 6/92

In a diesel application they are a blower not a supercharger...so they don't really provide boost in a diesel. In a petrol application the rotors are teflon tipped for sealing as the rotor turns around the case.


Earths are referring to the negative side of an electrical circuit.
