[QUOTE="ja_cain, post: 1254262, member: 11928"] As far as I know, the #1 limitation with the Heui system with regards to rpm is how fast the injectors can refill on the oil side once the nozzle size is increased enough to give the correct PW and fuel delivery vs. RPM. Hybrids decrease the ratio so that you don't need as much oil to displace the same amount of fuel but that only works up to a certain point. There are some individuals around here with some secret squirrel chit that may eventually trickle down to us at some point (modified internals/fast fill). Do some searching on the subject and you will find some good recent cerebral threads. [/QUOTE]
