Boost level?

[jardz91]

Just brought a boost controller. woundering what levels are safe to use and what level of boost guys are running?

Im running mine at 18psi however thats with a chip, FMIC, exhaust and soon to be water/meth.

 

[Bvandermaat]

I am going to guess you have a ZD30. I have seen people run them at 20psi but the safest bet is 18psi. A lot of guys are running at that.

 

[Lawry]

Yer thats a zd30, I can get to 20psi safely with water meth pre turbo- nozzle.
but 18psi is good enough for now, want reliability rather than all out torque.

I run 17-18psi with big exhaust, water/air cooler and remapped ecu. As far as I am aware the ecu goes into limp mode with boost higher then 20psi.

Will it even make a difference upping boost without a chip?

probably not. not recommended without intercooler either.
ZD30 runs enough boost in stock form, tho reducing boost creep is helpful.

 

[jardz91]

Have a 3 inch exhaust but no chip. Will that help at all?

 

[tweak'e]

help with what ?

 

[jardz91]

gaining more power by winding boost up without a chip

 

[Bvandermaat]

Only to a certain extent. Depending how high you raise it you could damage the pistons from having it to lean.

The best way to get more power out of a diesel is by using more fuel. On DI and CRD the fuel injection is ECU controlled so a chip is needed to boost fuel input.

 

[Lawry]

You can gain more torque but i wouldn't say kw's.
The more pressure forcing the piston down after combustion the more torque.
But as everyone says get a boost, and EGT gauge before you do anything.
hope that helps.
if you want more power just run a chip, then you can go nuts on the boost.

 

[tweak'e]

the problem is they already run 15psi+ boost without an intercooler. increasing boost also increases intake heat and turbo runs less efficiently.
you need to intercool first.

if you want power you need fuel, simple as that.

 

[loveit]

Id be adding fuel definitely not more boost.

 

[jardz91]

just ordered intercooler so when this arives would it be safe or am I better off just waiting till I can afford a chip too?

 

[tweak'e]

chuck the IC on, it will be good even without a chip.

 

[Bvandermaat]

Agreed the intercooler will help a fair bit. But as stated until you can get more fuel into the mixture there won't be that great of an improvement.

 

[jardz91]

chip and intetcooler ordered. lets hope i notice a difference doing both at the same time
