What is the diff. between a " stage 3 and stage 5 pump? Is there a stage 4? Is there anything above a stage 5?
I am not being sarcastic either. Just courious. Thanks
These are Jim Guthries "stages". The stg5 has the WORKS: hardened (AQ)shaft, inducer impellor, stainless impellor (race spec'd), fully ported bowl, stuffer plate, double bolted, and of course blueprinted
stg3 has fully ported bowl, inducer impellor, prepped aluminum impellor, stuffer plate, blueprinting
The difference is really in the strength
