Probably just has to do with what sizes they are using... You can have a SE cylinder that is faster than a DE cylinder of similar size in one direction... but slower than that cylinder in the other direction.

I also think part of it is that people see "2.5 dia ram" and think "OMG that's too big!" but the fact is, it has a very large 1.5" dia rod which takes up 34% of that piston's area(in both directions). So in reality that is like the non-rod side of a 2.0" single ended cylinder... But that same 2.0" SE cylinder will have a shaft on the opposite side... in PSC's case it is 1.125" dia shaft... which actually takes away 30% of the power from the shaft-side of the ram(when contracting).


In a nutshell... get a badass pump(don't skimp here), get an orbital that will give you the correct turns lock to lock based on what you want vs ram size vs pump output, and the ram you can probably go cheap on... just size it correctly! If it stays sealed it will work:beers:

makes sense they also tell me krc is there favorite pump for aetna style buggys do to the high rpm nature! my psc pumps whine loud at wot and it was kit from psc. figured pump and orbital would have more to do with how fast steering is than ram

correct. the ram simply works off how fast you can fill it with fluid. if you have a high GPH pump, then even with a larger cylinder you can have quick steering.
