WTF is a 12mm "H" pump?
ahhh so that means VP44 stands for very powerful 44? as in 4400hp??? makes sense to me.
PES6P120 is a 12mm P pump
PES6A950 is a 9.5mm A pump
WTF is a 12mm "H" pump?
P8500 or H1000
According the my Bosch book, there is an H1 and H1000 pump series. Has adjustable control sleeves, so it can vary the timing dynamically. According to the chart, H pumps are good for 100hp/cylinder. P-pumps are in the 75hp/cylinder range, in OEM trim.
