Author Topic: cant raise boost on KKK24... (Read 7275 times)

hello from Portugal

i bought a MBC to put in my car but the kkk24 as a metal line and i don't know how(on a cheap/ghetto way) to hook up the controller...

i could Skipp the controller... search and saw people just disconnecting the WG and the blow-off valve but wont that put much stress on the engine?
all said is a 1.6 diesel(rebuilt) with 1.6GTD external bits...
i just wanted some more power as i put 15" wheels and it losted the overall performance but don't know how to re-gain hp again...
i have big intercooler on front a removed the center muffler.
temperature is always low(can cruise at 140km/h-straight road-without even go to the middle of the gauge)so i think a little more boost is safe...

what can i do?increase fuel like in french topic and just sell the MBC and unplug the WG and blow off valve?
i will appreciate as much pics as possible as the ones in the archives most are out...

THANK YOU

You should get a exhaust gas temperature guage cause thats the one that tells you if everything is ok or not!!! the coolant temp will not tell you much!!!!

i don't know fo anty who disconnected the waste gate, only people who have them stuck shut, like me, if it would work i would use it lol, and if you did block the line it wouldn't really hurt anything, on stock fueling you'd be lucky to see 15psi haha. what you want to do is disable the bov, then the metal line ont he waste gate, cut an inch or so out, then stick hoses over top and host clamp them down, and run the hoses to the boost controller, may i also suggest that you take the adjustment on the wastegate, and adjust it all the way out until the screw gets all loose, then run it in till it first touches then tighten the lock nut. this will give you the most adjustment from low to high, and the lowest egts, get agt gauge though, the water temperature gauge barely means ***... and responds to slow.

didnt understand all you said but i dont want to spend more money on egt gauges...
this is a daily driver and i just want to have a bit more power to help push the 15" wheels .
can you have pics with a step by step on modding the kkk24 like you did?
if i can have like 90/100hp without smoke i will be very happy

i doubt you could do it with out any smoke, you could do it with out smoke underboost, i know i am in that range currently. theres not complex about it. on the far left side of the wastegate, the top of the car i would call there, there is a stud with a 3mm allen socket hole, and then a 10 mm lock nut, you'll need a deep well 10mm to loosen the locknut, then use the allen wrench to back out the stud/adjustment. it will get real loose, then adjust it in by hand or by allen wrench if the threads are tight on it, until it touches something, then tighten the 10 mm locknut back up. now your boost is set at 10psi on the boost gauge, which is the lowest you can go. then the metal line that goes to the wastegate cut an inch out of it and push a hose on each end. then run the hoses to the mbc. simple, now you can adjust you boost.

it would be hard to get pictures, the wastegate is back behind the motor, it's very simple though...

what do i use to keep the rubber in place?

RabbitJockey · « **Reply #7 on:** December 01, 2006, 04:21:14 pm »

a hose clamp

hello

today i start to increase the performance...
i increase the fuel(+-1500rpm)and went to the WG actuator and put the srew almost to the end.
that should give me a nice amount of boost.
i did the trick of the bolt to block the blow off,put 5the star wheel were lda pin sits 2 turns lower and turn the pin a little.
all that but the boost still wont pass 0.6/0.7 max...
could it be the blowoff still letting boost away?i put the bolt in and torqued but i didnt toque until it wont go more because i thought t could do something bad...should i toque it to the point i can go more(or close?)

if not what could cause only 0.6 pressure?bad lda pin orientation?should i put the starwheel in stock form?
i feel a nice kick in the but as soon the kkk24 spools but it peaks at 0.6 and the fun is over... :?

which way did you turn the screw on the wg? if you turned it ccw, then you loosened it for less boost, which is how i explained it for when you install a boost controller. you should not adjust boost with that screw as it causes a restriction and increases exhaust gas temperatures. you want to loosen it like i said then install a boost controller on the metal line.

the mbc works better on the garrets
you have to adjust the 3mm allen screw in for more boost
you can get it to a point where its turned in(screw),and you can use the mbc to sorta control the rate of how fast the turbo reaches max boost
but the boost is more or less adjusted by the 3mm allen

carrizog60 · « **Reply #11 on:** December 19, 2006, 11:44:44 pm »

the Allen pin is almost all in.
i did this and not installed the MBC as the hose that fits the MB exists is too much big to fit the turbo line...
i am going to try to torque the blow off a little more as it could be jammed to an open position and i stop torquing with it still open. :idea:

another thing...
should i put the star-wheel on stock position or let it sit the way it is now/turn it more?and the pin?
its doesnt have much angle...should i grind it?
what does in fueling/boost the adjustment of the pin?the aggressive side is faced to the driver side right?

sorry for all the questions but i think the pin adjustment and star wheel are a bit confusion and not accessible easy...

carrizog60 · « **Reply #12 on:** December 20, 2006, 04:01:08 am »

ok, this morning i torqued a little more on the blow off and went for a try.still 0.6/0.7bar...
do the broom stick trick and still 0.7 so i think the problem is not on the blow off... :roll:
the car does some smog but nothing crazy but i think it as fuel enough to pass 1 bar...
i feel the power as soon the boost kicks in but then it flats out...

any help? :idea:

edit:should i try to plug the line that goes from de turbo to the waste gate? :idea:

yea seriously... :lol:

just go buy the $80 dollar part and have some peace of mind knowing what is going on inside your motor.

15 psi boost is about as much as you want to run without an intercooler. You can do around 20 psi with an intercooler. you might even just want to increase the fueling and watch the black smoke out your tailpipe. afterall you're just trying to push 15 inch wheels right? you dont really want performance? 90-100hp with an intercooler is very realistic

Either way, get an EGT gauge, or a bigger downpipe, as it will help

Quote from: carrizog60

i have big intercooler on front

as for fuel i dont see that much smoke...i have seen stock cars smoking a lot more than i do now...it only smokes at very low rpm(1500rpm with WOT) but then the turbo stops at 0.6 bar.thats stock pressure...

i cant buy a 80dolar EGT because i am in portugal,shipping and customs will raise that value to almost is double... :roll:

i just want to know how can i raise more the boost and get more kick past 3500 because after that rpm it feels like stock...

another thing.if i raise the starwheel on lda could i add more fuel without more smoke?or down with fuel and more on the starwheel?
