Well to add to what Billa said about the BI prime-Just got a D-Tek heater core and had the puter apart so decided to check flow as compared to BIp. With 1048 pump 2 ft of suction hose in a 2 gal bucket, 1 ft of hose to rad, 2 ft. discharge to bucket from rad with 3/8 fittings on pump. Shook everthing to get air out and pull dicharge hose out to 1 gal milk jug--1 min and 15 sec to fill--did this several times . I know thst is not a test procedure like Billa uses but it would show the difference with the core. same test with the core and 55 sec. Had 3/8 fittings on pump as to run vinyl 1/2 od --so put stock fittings on(1/2) and re-tested--no difference on the prime but the core dropped to 50 sec. (on re-test and before used 3/8 silicon so it would fit on core 1/2 fittings.) The 2 gal bucket was below the pump and rad and at start of test water level was equeal to pump in-take but had to go uo about 3 inches to get out of bucket. Did have some times with the Via Aqua 1300 but couldn't get consistent results as via kept getting air and the via would noticeably slow down(flow) as the water level in bucket went down(so won't say now till I re-tape the threads(only place I can think of getting air)but it looks like it might do 2 GPM w/core and 5/8 fittings on block and pump.
And I am not knocking the Prime just sharing what little I have learn --Am follwing the threads about flow and dual Rads as that is what I am putting together and learning as i go along.
thought i might better edit this--these are my results done on my carport and on a rainey wed. afternoon using my Timex and my 1048 and my BI prime and my core- -your results might vary--but I don't think so by much.
