I use a meziere on a high revving 1.8L JDM modded "r" honda. I have a friend who has been running a meziere water pump with mega track miles on it on his C5 modded Z06 (right at 450lb.ft. torque) and he drives the piss out of the car (I think he is "slowz06" on here. His brother (who is banned here, LOL, where are you Rob?) has a very modded 500+hp mustang that he had a meziere but now runs some other electric pump (why am I thinking Stewart?) http://store.summitracing.com/partdetail.asp?part=emp-e558ar
and he has been happy with it (flows 55 gph). Some will tell you no it is meant for drag racing. Now how does the engine know the difference? You look at cooling capacity. The stewart pump keeps Rob's nasty fast mustang which shakes the whole car at idle nice and cool on hot days. Rob would tell you that if he was not banned. Hey Rob!!
