2011 Diesel UREA Exhaust and High Water.

Hi Andrew,

Inside a typical cast turbo outlet

Plate protruding out into the turbo housing to split the turbo discharged gas and the wastegated gas.

A split dump pipe.

And ... Sure. Like this would be legal. Once a wastegate opens the noise level shoots up. Since the turbine slices up the sound waves, the turbo discharge is never really what you could call loud. But wastegate discharge is a different story. If I was doing a split system, I'd run a muffler of some sort on both or join both pipes back into one before a single muffler.

darn it cant work out this multiquote thing...
anyways

yeah trust me i know all about this! Because mine has no muffler, for some reason the 3" pipe seems to amplify this REALLY loud rasp at high rpm- with the boost guage you can see it must be the wastegate, it only happens at over 8psi, or when the gate is really opening... hoping more boost (or no wastegate...) will get rid of this, as it is seriously LOUD. And that comes from someone who thinks his mates' 1HZ-T straight pipe is quiet....

So you think that there is serious potential in this split-dump setup? i mean compared to say a 3 or 3.5" dump pipe into a full system? i can definetly see where your coming from in that you could leave the exhaust from the turbo to the brake alone.

I dont think anyone's tried it yet.

BTW Just click the little yellow text icon (next to the mountain icon in the toolbar) and then cut'n'paste your quote

while we're on turbos and related, you know that the new MAN TGMs (and i think the TGS/TGX also) run a Borg Warner compound turbo setup? if you can see past the myriad of guards and sound baffles, you'll see them.
this, while may not give higher peak torque and power (except for the 240kw/1250nm version), gives the fattest and flattest power curve...
mmm, compound turbo'd fuso...:drool:

kay lets see if this works...

still didnt work- may have better luck next time...

My theory is cool water more than anything would simply prevent the DPF from working correctly, could throw codes etc.. Also food for thought. A chip burn and deletion is an excellent idea and tactic. There should also be little or no issues with 500ppm sulfur fuel then as well...

I'll have a look at the TGM we're working on at the moment. Maybe take some pics tomorrow.

try again...

now theres another vehicle that could benefit from a decantly set up exhaust system, though probably not as critical as the fuso's. Again, thier 'PM KAT' filter/muffler has plenty of wires hanging out of it that dont look like they would like to be hooked to thin air....

dieselcruiserhead, can i ask what makes you think this? im always good for new ways to get rid of unnecessary electronics.
