Well, this is what I know from the different pumps. The GTiR and Ve pumps are higher flow pumps, with larger pickup tubes. They both have vastly improved flow designs to prevent pump cavitation at higher rpms. The VE is the best design.
There is an oil starvation issues with the SR? I'm not sure I believe this is the #1 cause of failure. These cars have been heavily tracked for 15 years, this weak point would have been sorted out by now?
Has anyone asked questions about which oil was being used at the time of the failures at the convention? Seems like this year there were a lot more failures.
A little bit of this may be attributed to the stock oil pump and higher rpms, but I doubt it was oil starvation from cornering G forces. I could be wrong, but I have taken corners at Gs higher than .95 and have not had an issue with oil pressure dipping AT ALL. Both with a stock DET pump, and on my VE-T with a GTiR pump. Perhaps this is a real issue that needs to be solved, or maybe I am rambling. I just don't get all the failures.
