'Atomic' Manual boost controller

[justin911]

Hey Guys

I know this has been asked 1000 times (i've searched and searched ) but i installed my 'Go fast bits - Atomic' manual boost controller. I disconnected the old boost solenoid thing, and hooked up one end of the boost controller to the air intake pipe, and the other end into the actuator pipe (this went into the top plug in the stock controller). The little tube thing goes back into the throttle body?? (it used to sit on the bottom plug on the stock controller..) i plugged that hose up with a screw. A followed a few howto's from the archives and I think ive got it hooked up right. Problem is when I adjust the boost it lower it works.. stays at like 5psi.. but when i try make it higher it doesnt seem to change from when i had the stock solenoid on.. stays at like 8-9psi.. Alltho with the stock solenoid on i'd sometimes see it at 12psi for a little bit.. Im also usin an aftermarker boost guage to check the results.

Anyone have any ideas ??? Or am i missing something.. like i need something else.. to make the car make more turbo goodness ?? hmmm.. ???

my cars a r33 series 2 gtst btw.. 3" exhaust, fmic, safc2 etc..

thanks heaps

a took a pic just now.. u cant realy see it.. but it may help

Also i was looking in the little manual that came with it.. it said if my problem occurs ive got it wrong around the wrong way. It ses make sure the arrows are pointing towards the actuator thingy.. I double checked though and it definetly is.

I just checked it again with the thing fully closed, it doesnt seem to make a differance if its open or closed i thought it did before.... keeps going to like 7-8...

i want 10-12 or something :~(!!!

hmmm i tried it just now with the arrow not pointing towards the actuator.. didnt make a diff at all.. still 7-8.. when it was fully closed/open

here is pic of mine I know its diff type but may help

[justin911]

thanks heaps for that

It looks like its setup the same as mine.. arrows points towards actuator etc..

That pipe that goes to the top plug on the stock solenoid thingy where does that go back to ? Down to some bigger black plastic tube, and then into the intake pipe right ?

and not the actuator ? I plugged mine with a screw..hmm but that shouldnt make a diff ?

thanks again

The pipe off the controller goes into the turbo actuator, so its straight from pipe (as you see it) to boost control to turbo. The other pipe goes to plumback pipe which aint being used.

heres a pic of what it used to look like before.. and what it looks like after..hmmm...

go the mighty paint!!!

???

grr ok i hooked it all up to the stock stuff... and connected the 2 pipes that go into the soilnoid into the boost controller.. i tried it with it both ways around... and its still sitting at like 7-8. its fully closed.. maybe im understanding/testing it wrong.. if its set to be at like 5psi or something... it should never realy get past 5psi right..

I dont wana have to pay for someone to get this going for me grrr !

I'm pretty sure you also gotta disconnect the electrical connector that is attached to the stock boost contorller solenoid. Its a small plug with like 2 wires only. Im guessing its probably because of that.

I have the same bleed valve as you.

Here was my problem. Car would boost up to about 10psi, and then gradually creep up to about 14psi by 7000rpm. Keep in mind this is with aftermarket computer/turbo/cooler etc.

The thing was, I wanted 16psi right from the start. None of this gradual increase crap. What I managed to find out was that someone had fully closed the valve between when it got tuned (at 16psi) and then I picked the car up.

So with NO valve (valve closed), my car was running the minimum boost which was 10psi at 4000rpm up to 14psi at 7000. I opened the valve 1 turn, nothing... 3 turns, nothing... 10 turns, instant 12psi and 15 turns... 16psi at 4000rpm. By turns I could be meaning half turns cause I can't remember but the point is, you really have to wind that thing out many turns before you will notice an increase in boost over stock.

Also as far as I know, the valve does not let you lower your boost. You can't make it run less boost than stock. However, winding it out (if nothing happens just keep winding) should increase your boost to where you want it.

Also, for the GFB Atomic, you need an ALLEN KEY to open it up. Make sure you using one

I think you might be right Dee..

Last night i took out the pipe that connects to the T/air intake originaly (like i should have 3 days ago grr) and it had a bloody restrictor in it.. so i've replaced that cable now.. and had it closed and it didnt seem to go over 8psi.. im going to try the unscrewing it 50 times trick now and see what happens.

I'll unplug the electrical connector going in the stock solenoid first to see if that does anything as well ? I thought that *just* opens it at 4500rpm ?

ooh im so excited, one of these ideas has got to work

thanks heaps

[justin911]

yay thanks heaps Dee!

i turned it back heaps and heaps and it went to like 15-18 for the split second b4 i nearly had a heartattack.. So its definetly working. Gonna take me ages to work out how many turns she needs to get what im after but its working atleast
