Industrial injection has different stages of modding cp3,s ,I was looking at the sidewinder banks project ,they said the cp3 unit is capabel of 800 hp ,don,t believe everything you read,there is no way a stock cp3 can deliver that much fuel,if it was like that ,company,s like industrial injection,and other company,s would never sell any modded cp3 pumps .
the dual fuelers are 2 bosch cp2 pumps with the same output ,combined they deliver fuel up to 1200 hp ,according the manufacturers,I would say 2 x 600 hp =1200 ,if one stock pump was rated for 800 hp ,it would have said 1600 hp,I guess I,m 50 hp off .

Modified or not, it's not worth arguing. The point is that you don't need two pumps for 700hp. You can get there with one.
Without data, it's only speculation. Do you know for a fact you're losing rail pressure, by reading the rail pressure data from the ECU? If so, have you checked the supply pressure and/or tried increasing it? It's an easy test if you have an adjustable regulator.
It's possible that the compressor wheel tips are going supersonic, but if that's true he'll know for sure pretty quickly, because they'll not be attached to the wheel anymore. This is typically the limiting speed of a turbo, and other precautions should be taken from getting to that point. A compressor can reach this speed at many different operating point. If this were truly the source of the noise, one fix could be a different turbine wheel or turbine housing to reduce the drive energy. Or, go to a different compressor with a more appropriate map (it sounds like he wants a higher pressure ratio and mass flow capability).
Industrial injection is making several single pumps that are modded ,and support big horsepower,the dual fueler was my firs option,because the 3000$ price is cheaper than a single 230% more cp3 unit that they sell.
+ that if one fails ,there,s still rail press.
I have a rail press gauge ,and a egt gauge ,I can raise rail press ,timing ,duration ,and monitor whats going on ,and what happens during loading the engine.I can even log data for an half hour .
the blade tips are not overspeeding ,because I can hear the turbo,s inside the cap spinning (very loud) and its easy to hear if I press this unit to more pulsewidth,the engine is holding back during acceleration,especially in overdrive lock up where the load is at its highest point,and the turbo,s are not at max rpm yet.(the unit throw more diesel to spin the turbo faster) at least that is what I.m thinking,but I could be wrong.
Maybe I use the wrong word (popping ) it sounds like the engine is loosing power ,then start making power ,then power loss,power build up,power loss, all happens in a few seconds,so the intermitting is very fast, so on and on until the engine accelerates trough this rpm range up to higher into the powerband ,where its gone ,when this occurs the truck starts shaking a bit .
I know off a lot other guys with these engines that said they have had the same issues like me ,until they modded the cp3 ,or upgrading to a bigger or duals.
Fuel system: He just hasn't given up enough actual info.
Turbo: On going supersonic I've seen some go BOOYAH once and suck all the turbine blades through the motor.You can guess what kind of mayhem followed I've seen some start popping and no damage at all. Also seen lots of things in between like real slight erosion of the trailing corner of the blades.
