Why should I edit my post? It would make me look silly. I expect a message from the moderator if this is nessesary.
The post i refered to stated that stock U return pump flows 2.08 l/min at 2400rpm (messured by Woody). Frankenstein messured his -72 XL supply pump flow to 1 l/min at 2000rrrpm, which equals 1.2 l/min at 2400rrpm. Return pump is then 173% of supply pump with sportypump-conversion.
Look at this Victory-link (credit to Panic who publicated this a while ago): http://victorylibrary.com/tech/OHV-pump-c.htm
This idicates that the factory ment that 143% was a good ratio. This means that supply pump could in fact flow in the region of 1.45 l/min at 2400rpm before return pump is overloaded. Again according to Frankenstein, Jim messured stock U supply pump to 0.08 l/min. So....something is not adding up. Why is there no advantager in increasing supply flow on BTSV?
