Cranking up the boost on the 4D56TDIC

[OTEP]

I read back then that this could be done using washers/spacers on the wastegate. Can anyone elaborate on this? I'm looking for a cheap way to boost my rig's output.

How does one do this?
Is this safe?

Salamat.

otep,

i've heard about that and am planning to do it, too. the advice given to me was to make sure i have it calibrated using a boost guage and an EGT. these are the two most important readings to look at when cranking your boost. nice meeting you earlier

ferdi,

Tataas ang cost kung hahanap pa ko ng EGT at gauge, eh. Kaya plano ko na lang sana itanong sa kanila kung ilang washer ang ginamit nila sa set-ups nila. Hehehe.

Nice meeting you too ser. Nag-off roading kami after. Akala ko tataob yung Safari. Baka mamaya may pics na si Glenn for viewing.

putting a boost gauge is important if you want to increase boost. to lower cost you can buy vacuum gauge they are just the same.

what we did to increase boost is look for the rod that connects to the wastegate. put a spring to increase tension, thereby delaying or making it hard for the wastegate to open. this is where you will need the gauge so that you will know how much tension the spring will delay the opening of the wastegate.

if you are getting 8psi stock you can maybe increase it to 10-11psi. just watch your temp gauge that it stays normal if it increases then you are over boosted. IMHO.

Or you could just get a cheap Man Boost Control from 2211. Php3000+. I-PM mo si Yellow. siya yung gumawa nito.

OT:: Otep: IMO, kaya ng Paje yung obstacle kahapon, but you have to risk some body damage. Kung tipong life or death situation or patapon na ang auto, oks sana isabak dun sa course. Nanghihinayang ako kse mamaya magasgasan :D

[OTEP]

pajerokid,

Kung may rock skis lang ako hindi ko uurungan yung moguls. Bad trip lang iyong plastic side sills, eh. Mukhang hindi kakayanin full weight ng Pajero.

Pero ang sarap sa hill! I'm on top of the world! Wohooo!

Your manual boost control advice has been noted.

[pajerokid]

Pare, i hope Glenn gets the pics posted! Oks yung kuha ninyo pareho, with the rear wheels lifted! :D The pajero looked very impressive going up that steep hill!!!! :mrgreen: :mrgreen::mrgreen: I think mga 35-40 degree incline din yun! Sana binaba mo na dun sa boulders hehehehe :twisted: There's always next time!

Your running boards will definitely get crushed if you attempted the moguls.

Nawala sa isip ko yang boost control, when i got into other stuff. I'll probably get one next payday, budget willing. Si KC interested din e.

Sabi ni Mr. Woodfire, nag increase yung output ng strada nya from 75(?) at the wheels to around 90+, a very good increase for the price.

Pare, do you think lalakas ang consumo?

[OTEP]

Pare, do you think lalakas ang consumo?

That would depend on your right foot siguro.

Hindi pala gumagana yung handbrake with one rear tire lifted. Walanjo, montik na gumulong pababa ng bundok yung Pajero ko ng hindi ako kasama. hehehe.
I was in 2nd gear Low during the ascent.

NYEEEEKKK!!!! GANUN!!! 8O 8O 8O 8O :lol: :lol: :lol:

If you plan to rise the boost, why not try first doing some intake and exhaust mods? Turbo engines are more responsive to such (bigger and straighter exhaust piping, and free-flow intake box).

Should you raise the boost, do get a boost gauge to keep you from blowing up your engine. You may also want to put a hood vent for your intercooler to make cooling more efficient. What you should keep in mind is that you'll want to keep your engine/turbo internal temperature at bay and running efficiently should you crank up the boost a bit.

What's the stock boost of the 4D56? Make sure also that your fuel system is up to the task of the amount of boost that you'll be upping from stock, i'm assuming that around 2-3psi is still a safe level (please correct me if i'm wrong).

Sayang di ako nakahabol yesterday... naipit yung car ko sa registrations sa village namin... bwiset na emissions testing, di dumating yung tester.

[OTEP]

vinj,

I can't do intake mods. My water fording capability will be compromised. I don't know about the exhaust. The current one is pretty well designed for off-roading.

I'm just looking for a few more horses. Just in case I add some weight on the truck soon.

OTEP,

magpapataba po kayo? :mrgreen:

[OTEP]

mbt,

Oo, sana. Saka dumadami ang chicks ko, eh. (joke lang, baka matepok ako kay mommy Yoli nito). :mrgreen:

incidentally, i still have my old hood (with provision for scoop) in my garage! Im willing to let go at a very very very very cheap price. Tipong enough for a boost controller :lol: :lol: :lol:

[vinj]

Pajerokid, this hood of yours is OEM type complete with the duct? For intercooler body Pajero? If you want to dispose it at a good price I'm kinda interested in that if a deal my dad and i are trying to work out pushes through (give me a couple of weeks)...

Otep, the exhaust pipe upgrades should help then. Tapos lagyan mo ng racing muffler at corvis wing para mas astig ca sa tsiks. :P

Yep you can increase the boost of the turbo by adding spacers or washers to the wastgate actautor can, Increasing the tension of the spring inside. I had a boost gauge installed and added about 2psi of boost, acceleration improved, consumptions of fuel depends on your foot :D

[OTEP]

Yellow,

Detailed instructions naman. Saan ka kumuha ng materyales? Salamat. Might be a good weekend project.

[Yellow]

OTEP,
All you need is a socket wrench #12 and a couple of washers.

The washers were bought sa hardware ordinary washers lang, I bought 10 pcs for 5 pesos, choose washers that can fit the bolts of the actuator, all you do is take off your actuator can, there are two bolts the secures your actuator can on the intake manifold, just place the washers in between the actuator can and the intake manifold, then screw it back on.

Two washers can add about 1 psi to maximum boost, to be able to install the washers easily you can super glue the washers together.

Be careful not to tighthen the bolt to much, the intake manifold can get loose thread easily.

If you go beyond 2 washers you need a longer bolt, i added only 3 washers the stock maximum boost of my engine was at 10 psi now its around 12 psi.

I wanted to go to around 14 psi but i was afraid the engine couldn't take it so i set it at 12 psi, I think a +2psi wouldnt be too much for the engine.

It would help also if you installed an open type filter and larger exhuast pipes and a free flow muffler.

If I had a digital camera I could take pictures of a step by step guide.

The mod helps in low end acceleration as the actuator doesn't open too early, it doesn't let boost escape too early, so it helps in spooling the turbo faster.

I hope this help just drop me a line if you have any other questions.

[OTEP]

Yellow,

Hindi ko maimagine. Sana may picture. Pero I will try to visualize it in my mind. Hehehe.

So in essence, I am lifting my actuator can?

[Yellow]

OTEP,
Yes you got it, so when you lift the actuator can the tension on the spring inside the can increases, so you need a higher air pressure to push the spring, to open the wastegate.
