Exhaust Manifold.

Yes RP is high, but that is irrelevant.

I dissagree with that...

No pump is going to hold CHRONIC flow AND CHRONIC pressure like that...not without having multiple HP pumps hooked up, and i just dont see the need, if you just ran bigger nozzles and dropped the pressure down, everything would be happy, HP pumps wouyldnt be getting RAPED, fuel wouldnt be being superheated, just less to go wrong, and less upgrades needed for big power....yes 200 hp is possible, but your pushing everything to sky limits on the fuel system, im sure if you just put big nozzles in and dropped the pressure, you could happily run the same 200hp, with way less pressure, and have TONNES of flow overhead for future tuning....

Bear in mind I dont run an XUD, i run a dw10 with a ve on it...hence im comparing the same motor here, 200 bar vs 04309584957834bar CR...dont get me wrong, of course the high pressure will help, it can only make it better...but with the levels your talking, its just insane / pointless IMO from a tuning perspective....

Dont like to mension it...but cough TDI boys cough...pretty much the FIRST thing you do, is change out the nozzles....cummins boys....first thing you do nozzles... I know this isnt always common rail, but its DI, and cr or not, the nozzles are ALWAYS restriction in there stock form as there designed to be as clean as physically possible / most MPG strict at X hp....
