Where's My Actuator Pipe?

I need to disconnect the actuator pipe to run open boost .. I dont have a boost controller yet so apparently this is a good way to see how the car will behave if I did have one installed..

Only thing that controls the boost at the moment is the wastegate spring.. can anyone point me to the right pipe / hose to disconnect to achieve this? Thanks in advance

engine bay pics are as follows:

Find the actuator and pull the vac hose off it? There is only one...

And is the car "stock"? AS it wont behave much at all once it hits boost cut, or the turbo explodes

Its got a few mods, and yeah ill be watching the boost like a hawk.. I dont produce full boost until around 4k, so this test could be interesting to try out

had me confused as hell here sorry, so basically since the external wastegate does what the actuator used to do I'd be right in saying yank that hose of that since the stock actuator / turbo setup is long gone

It will probably BLOW UP judging by the amount oil coming out of you rocker cover vapour hoses

yeah thanks for noticing but its not like I'm gonna be driving it around everywhere like this, I doubt ill go over 3k its just to see if the boost will build quicker since my lag is shocking

just took the hose off and went for a drive, made stuff all difference car is still laggy as hell.. was at about 14psi at 3800ish rpm .. so im highly doubting a new boost controller will make it any better.

I was really hoping to produce my 19 pounds (current spring setup) at a lot lower revs with this td05 but hey, im not really sure what to expect running open boost like that.

I suppose i should mention that its a knock off chinese td05, probably explains a few things.. Although from my experience this turbo produced more hp than a genuine mitsi turbo on my last dyno run @ same boost but they generally dont last as long.

ummm removing the VAC line to an actuator wont do anything (if you still had one)

You need to wire the gate/actuator shut if you want to test if the turbo gate is opening prematurely causing poor response (if you still had one)

And i say - "if you still had one" because fk me...

You have an EXTERNAL WASTEGATE - you do not have an actuator... The gate is the actuator.

So no idea what anyone in this thread has been talking about... look @ the fluro poofter pink thing in the pictures!!!

So... as before - removing the hose, same in this instance, isnt going to do a thing.

If you want to test the GATE spring being the cause, just take the gate off and put a blanking plate on it, you'll soon see if its gate creep causing the problem or not

And get rid of that silly filter thats blowing oil over your engine bay. I kid you not when i say this... that filter will give you a fire in your engine bay when it spits oil when things are hot. I've seen 3 cars catch fire because of those retarded filters that server no purpose other than getting an insurance payout for a burnout car.

Oh, btw - insurance wont payout because that's your own fault for a illegal, and dumb mod :(

wow thanks, kinda.. :thumbsup:

Just so were clear, this is New Zealand .. and its perfectly legal..

I didnt even install the filter thing, it magically appeared after mechanic installed the turbo, if its a stupid mod fine, but I just left it on cos i assumed it did something. Im not a mechanic!!, hence why I use this place to obtain answers, so enough with the flameing.. purple poofter thing??? come on, does it need to be black or something.

but thanks, for your insightful answer I do appreciate it..

btw - the oil all over the place is from a crack in one of those pipes, yes it needs replacing..

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!

      Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !

      By GTSBoy · Posted

      It's almost certainly going to be some amount of pads compound transfer onto the rotors. It will probably go away after you've run them for a bit. If not, pull it all out, lightly sand the rotors, scuff the pads, and rebed.
