Hi volume oil pump
agreed Fishy
i havent had any problem before.. not with the stock hv pump in my 340's or any of the 318.. no i aint doing any dragracing at all.. so the only difference i have notised is that the 340 engines had higher idle pressure than the 318 with must be that it reach the demands/leaks in the system.. tough i totaly agree in the fact that why the hell pump all the oil u dont need to maintain the preasure trough the regulating valve in the pump... :read2: byt im kinda ok with the hp loss and its only ca 20% more ... who knows.. maybe soon i need oil for some turbos:P:P
