For a single turbo road car (450atf) is a Davis Craig water pump a good choice over stock cooling.
I am planning on running one of these in due time, they are apparently very good pump and have the benefit of giving the same flow rate now matter what the revs.
All gallons are US based and not imperial.
The standard pump is good for approx 30 gallons per minute, but played with can be increased to 45 gallons per minute.
The davies craig pump flows 110 litres per minute which is equivalent to 29 gallons per minute.
I have 5 of these pumps in stock if you want one?
That\'s only the larger one though. The small one is 80lt / min
They are great for sitting in traffic but can take an age to warm up !
