Boost solenoid restrictor

[Sleepyvr4]

Iam guessing its bar not psi ...

 

[Jimmy_EC5W]

Yep sorry just move the dot over one to the right. So basically to round up, just over 1bar first time, 7.4psi second, 5.5 third. Before any of this I was previously running 5.7psi.

So any ideas?

 

[VOLK]

Yah it'll be barometric. Boost cut at 1bar sounds about right on stock rom.

1bar isn't 10psi. 1 bar = ~14.7psi.

If the lines are open you have no pressure to the wastegate so uncontrolled boost till you get boost cut (see thats why it exists). .74 bar is about std and working. 0.55 is not working. Can you say how it was hooked up for this? Possibly you have an intermittent solenoid problem....

 

[Jimmy_EC5W]

Well the car is almost stock as a rock. Had the turbos replaced from 7t to 9t, but it was still doing .57 even before that...

I have an exhaust and blitz pod but doubt that's got to do with anything. Why would my car be running so low boost, taking out that restrictor hasn't done anything for me. Should I reset ecu? I've done it before once a while ago.

There is a slim chance it could be because that boost solenoid is designed for a different system. You could get a three port or a MBC or EBC.

Or it could be a stuffed boost solenoid.

 

[TME_Steve]

Ah yes, different turbos potentially different wastegates and therefore different behaviour.... More likely the solenoid is not working and that can be due to the solenoid itself or almost any of the plumbing not being factory.... Changing a tpiece on one car resulted in a 4psi change.... Given it was 0.57 before, somethings probably wrong. A 3 port and tune is the correct fix, although a $30 mbc would also give you a decent boost increase.

Hey guys, Just wondering if this is the factory boost solenoid or an aftermarket unit?

 

[godzilla]

That's not where the factory one even sits. So yeah, aftermarket it looks,

 

[ConnerS]

isnt that to do with the traction control?

 

[Badger]

Yeah thats the TCL solenoid and I cant remember what the other one is

 

[Anton_Willows]

ok thanks, thought so.. having the mines ecu i didnt think it would be standard, I guess same goes for the fuel pump but will have to have a look and see.. obviously I got more than I bargined for when I bought the car, guy reckon'd it was virtually stock! lol

 

[ConnerS]

If I was to have a guess I would say you'd be running stock pump and stock solenoid. Could be wrong though.

Guys
That's the TCL/ASC solenoid for traction control etc.. in the pic. Found on PFL usually!
Don't touch it. It looks similar to a boost controller!
The boost controller is under the throttle body under the air intake duct above the ttransmission.
You can track the vacuum lines to it.

 

[Anton_Willows]

Thanks.. Will have to have a down there

Is there any way of bypassing the solenoid as I have snap the brown pug. So I can run my car until my new one arrives from Sydney

Hi guys, I've got a Blitz SBC ID I'm looking to hook up.
Someone had installed a piece of crud Atomic Boost controller to the car and made a mess of all the vacuum lines etc, there's not even any connected to the solenoid.
Does anyone have a pic of how all the lines should be in stock trim so I can set it all back up stock before I install the SBC.
Will I need the stock solenoid hooked up at all with the supplied solenoid from the SBC? (Only ask this because the stick solenoid has one of the tips broken off)
Thanks

I know somethings not right as the car is running excessively rich (200-250km/tank) and if you use more than 60% throttle she drowns in uburnt fuel.
I have a Blitz R-FIT to hook up also which will fix this issue as long as everything is set up correctly.

Hi Guys,

Just about to give this a go, it'll be my first power mod to the vehicle, bit of history about the car.

Bought second hand, 140,000k, FMIC, dump back 2.5" exhaust, HKS BOV, gauges (which currently read 10psi in 3rd at full spool).

after pulling the restrictor out should I get an ECU tune done?

I have been looking here http://www.ozvr4.com/threads/tme-introduction-and-tuning-work.11614/ and thought that with $500 to spend that removing the restrictor and a tune would be the most cost effective sensible upgrade.

I'm in Sydney, yet to go to any meets or anything.

Honestly, a $73 3 port makes the factory solenoid look silly. I can't think of an evo, sti, vr4 that we haven't changed the factory solenoid to a 3 port controlled by the ecu or an aftermarket boost controller in the last 18 months or so.
