Message: [QUOTE="Wayne, post: 499615, member: 863"] We have a fully functioning twin HPOP kit available. It's actually a very nice kit. With proper tuning, you won't bend spool valves. The problem with a lot of the most aggressive custom tunes, including our conventional insanity tunes, is that they lie to the pcm, making it think there's not enough HPO, maxing out the system. This is good for a single pump, but with twins, pressures get too high. Our system also has a safety blow off valve, so it shouldn't get destructively high. The only disadvantage with our twin pumps is that the low pressure oiling system needs to be upgraded to properly take advantage ot the twin pumps. Every truck we've had with twin pumps over 4500 rpm's has burned rod bearings because the low pressure oil pressure was sucked too low to protect the engine. On the upside, we're not near maximizing the pumps on the 430 cc injectors. You'll never run out of high pressure oil with these. Shawn's right though, no real "need" for twin pumps below 600 hp fuel only. Not too many 6.0's ever cross that line so they haven't been a hot seller for us. [/QUOTE]
