The first graph shows electric water pump flow vs press, typically the ratings on these pumps are against free air discharge, once some restriction and therefore pressure differential is present their "advertised" flow numbers diminish.

The cavitation is present on the LT5 pump at high rpm reducing flow, it is actually a pretty efficient pump, even by todays standards, prolonged high rpm use could present problems.

Jerry's recommendations, earlier in the thread have proven to work well for track use.

The pressures are measured on the block side of the system.
