ZD30 Boost low under load

[rochjas]

Thanks rochjas,
I blocked the egr pipe today. Just waiting for the Dawes to turn up now.

Hey CrossCountry,

Well now your on your way. I did my EGR the same time I did my dawes and needle valve... was told that you might throw a few error codes if you do the EGR before hand.... could be wrong :-)....
But a least you have made a start.... well done

Have you done an exhaust upgrade yet???
On the Di motors you'll go into limp mode,
from over boosting

Hey 3dogs
I have not done mine yet as the exhaust is in newish condition in mine.... Its on the list to be done but not yet... I have not had any limp mode issues... I am guessing thats because I did my EGR block and dawes at the same time...

The gauges is the best mod IMO lets you know
whats going on so you can adjust your driving style to suit.
I would say mine would have blown up with no NADS.
now I'll put it against anyone with confidence

I done the gauges already they had been in for 2 months now.... Very true about telling you know what your engine is doing.... It's actually forced me to modify my driving style a little.... Then done Dawes and EGR block yesterday. About to order provent and will have that installed in a few weeks.... Love to be doing the Zorst but $$$ are a little tight ATM.... Might have to hit up the minister of finance for a loan...

Hey Threedogs,
Where do you get the Zorst exhaust from?

[CrossCountry]

I got my injectors and new glow plugs back in today with the EGR blocked. The blocking certainly made a difference to how much more boost I can get. Going much better.

I have a Redback 3inch system on my Di. Hi flow metallic cat and one rear muffler, soon to be removed. There is a massive choice is exhaust systems, prices to suit too. In my personal opinion, you don't need to spend the cash for the top end systems which are $1200 plus. I paid $900 for my Redback system and I fitted it myself. As long as the cat is hi flow and has the metallic filter, not the ceramic type, apparently metalic is better for performance and filtering and doesn't block up as much as ceramic, and it has mandrel bends in the elbows of the pipe. Mandrel bends on exhaust is when where the pipe is bent the diameter of the pipe does not change through the bend, on the other type of bend, mental blank *insert name here*, the bend in the pipe reduces in diameter, caused by the machine that bends the pipe.
Then you got the material the pipe is made from, in my opinion again, stainless is a waste on a diesel, unless your going for the look. Mild steel will do the exact same thing.

Cheers.

Zorst is just short for exhaust,
@ rochjas if you don't drive your Patrol hard you may not go into lime mode.
My exhaust is 3" all the way no noise what's so ever, combined with chip
gives pretty spritely performance. I have heaps of boost which doesn't bring on
limp mode. Fuel economy is 12.5/100 around town on 305 MTZs muddies,


X2 with Mudski shop around for the bigger items like bigger exhaust and tigged
intercoolers, I've found Diesel Smart to have best value for money C/O intercooler.
I have nothing to do with them, I just added up what they offered and compared to others.
The others only pressure tested to 30psi not 60psi like DS, 33% bigger like most others,
5 yr warranty beat that, and priced so its very affordable check their vendor page
