Well i looked at the intank pump on my MS3 and it looks identical to the SVT Focus. High pressure, high volume 255lph. These pumps put a minimum of 60 PSI, so there has to be variable voltage going to the intank pump pushing it higher than 60. On my truck, ive seen these pumps hit as high as 78psi at 5580 RPM.
So, i think the stocker has no problem keeping up with volume to a modified CDFP at this point. Only time will tell what the intank is maxed at. Im really wondering the program differences between the 6 and 3. It must be substantial enough that Cobb abandoned the MS6 altogether. Food for thought.
The pump recieves 10.2v at idle. Anything other than idle, it recieves 12.3v. These differences are triggered by a relay which is activated by the ecu anytime the rpm goes above 800. The pump itself pushes 71psi. The fpr in the tank brings that down to 65psi constant. I wouldn't be so sure it's the same pump as the svt. Just about every in tank pump walbro sells looks identicle other than very minor differences for fitment. Same goes for Denso and just about every other fuel pump manufacturer. The pumps internals are what makes it what it is. There is a number on the stock pump, but there's really no way to derive anything from that unless there's an insider at Mazda in Japan. Whoosh has a stock pump sent off to Kinsler to be tested. He sent it today, so we'll know exactly how much fuel the stocker is putting out at that 12.3v probably by the end of the week.

So Driver311, you "had" a CDFP from PG, installed it, it cured your cut issue up top, and then you had to remove it? Sounds like some folks have the answers but are being a bit sketchy with posting the results. No offense my man, just getting the feeling you and loosh know more than your posting. Thanks for the info. Eagerly awaiting more data so I can purchase my mbc, map clamp, cdfp, etc. Thanks bros ... Mike
it's my understanding that this PG cam pump locked up while dyno testing on Driver311's car
the incorrect parts were sent to PG which is why there is a problem/delay getting a pump from them at the moment
I'm scared that the pump bench testing didn't or wouldn't reflect incorrect parts before shipping to the end user.
I'll be sporting a CP-E cam pump with confidence
the first batch of parts and pumps we used all worked with flying colors and continue to do so. bad batches or runs of a machined item happen whether i want them to or not. the pumps are not simple pass/fail. i can tell you that you can make nearly a dozen hard pulls or more before the pump even shows a problem. until the pumps are subjected to repeat examples of hard use in a hot engine, the pumps would show as being fine. no bench is going to be able to fully replicate those kind of conditions. the tolerances are really tighter than i can explain.
still, i'm not happy with it at all, which is why i am less inclined to continue working with the people manufacturing these and more inclined to working with another company.
You should always keep your stock parts.so theres no guarantee the pump i got will work without a problem? should i hold onto the stock pump in case anything happened?
this whole pg cam pump thing is a huge let down

are you nuts ?? my stock pump couldnt keep up for s*** ! the pressure would fall below 1000psi ! that is wayy too low for DI. the new pump holds a solid 1800+ psi. i see it pass 1900 sometimes. the pump is a must have for anyone who wants to seriously mod this car. i am very confident my car would have blown up by now without it. the car holds boost longer and has a very safe10:1 AFR even at over 20psi in the cold !

the pump that was originally on your car was trash and thats why mazda recalled them. You fall into that Service Bulliten for a replacement IIRC. Alot of the newer cars dont have the fuel issues that yours and mine did (reason mine blew).
So when some people dissagree..they are not in fact, totally wrong. I noticed a HUGE difference on my recalled pump and should be enough to supply most peoples needs. Now for you and I, along with the big turbo guys (im ordering mine ASAP).. even a 100% working, replacement pump wont be enough. This is when we turn to Ken or Mrlilguy

maybe i am mistaken but i thought along with the replacement pump, there was an ECU reflash as well?
thats what i thought, you aren't getting a new pump per se, but a new solenoid and a reflash. the internals of the recall/TSB pump are the same
