Boost Control setup

[Jay2525]

Ok, so another thread Ive started, i know i sound like a noob, but just want to get this right.
Enclosed some pics, one of under hood, one of kit. I have colour coded parts, just need someone to point me in right direction.
The hood pic, i have ringed the hose i think it is i connect to, on the other pic i have colour coded all the ports on the t peice and the controller, what is confusing is that there is 5 point on the controller and t piece, but only one pipe to connect to, does one get blanked or left open.
So help here guys would be great.5617656177

Just a matter of funds at the moment

green vents to air
white goes to red(controller)
yellow goes to red (towards throttle elbow)
blue? goes to red (pipe circled red)

i had that boost controller and the t-piece jammed and made the boost spike massively, i got round that by removing the ball from the t-piece.
i later got rid of that t-piece completely and joined the red pipe from the controller to the t-piece already on the car instead of the factory controller.

the later method ran fine until i decided to break the car

fair enough but from personal experience they are bad .they spike all the time poorly made.
wind the boost all the way down and still hit fuel cut.
just a heads up .

Have used both TurboSmart "boost tee" MBC and the one featured by the OP and it was complete pants. Had exactly the same problems as Mark.

[Jay2525]

would this be a better one for now.

Also ash, throttle elbow being the black pipe, (noob question again).
So the yellow and blue tap in to the pipe I have put red ring round with the arrow facing away from the big black pipe (cant remember what its called).

It's a few quid more, but I cannot praise this MBC enough: http://www.3barracing.com/product_6.htm

I used it for nearly four years with great results and no problems. In fact, once I've replaced the downpipes and fitted my AFR gauge, this is going back on!

Nope, the controller pipe and the fat pipe(throttle body elbow) need swapping.

Instead of cutting the pipe to the throttle elbow i used a piece of old pipe, so u mean swap the blue pipe coming from elbow with the black pipe that goes to controller.

Get ya now

[Jay2525]

Ok, just gone for a spin, boost turned all the way down (anticlockwise) as far as it will go, basically a slight toe down boost gauge of of the dial and judders like anything, thinking I may have it turned all the way up but looking at it, it looks turned all the way down grrrrr!

[c0xxy]

I would say youv still not quite got it right or the t-piece is sticking, more than likely. If u undo the one side of it then take the gubbins out, put it back together, it should be fine.

Says on this vid that the arrow on the t piece should fave the controller?

[Jay2525]

Whats gubbins, sorry lol

[c0xxy]

Can't watch the vid cos working. The instructions all say arrow faces wastegate.
In the t- piece there is a ball and spring which make the tpiece directional. If u take them out or replace the tpiece it will work however the pipes are attached to it.

And wont do no damage?

[c0xxy]

So long as youve not got your boost to high.
I'll get you a pic tomorrow of how mine is set up. I'm not using that tpiece at all.

Right, gubbins out, completly different this time!!! Started with boost turned down, and have gradually turned it up half a turn at a time, gauge is now hitting 1.5 bar and holding between 0.9 - 1.1, just hit 6.5k revs in 3rd and no fuel cut, bit worried about turning it up anymore incase i do damage, dump valve is much louder now as well.

[c0xxy]

Sounds good, mine used to hit 1.3 then settle at 0.9. I wasn't hitting cut doing 3 rd gear pulls but when dropping a gear or two to overtake it would some times.

Mite do one more turn or so then think will hold it there, thats it for tonight though, missus is starting to moan now lol. Thanks for you help mate, sorry to sound like a noob lol

[c0xxy]

Lol, mine does that too! Don't worry about that, atleast your doing it yourself!

[Jay2525]

Must be a commen thing then with misses and cars lol, so i leave the ball and spring out all the time now then, will stick them somewhere safe incase there ever need.

[c0xxy]

I binned mine... Ball n spring that is. T- piece followed soon after

1.5 bar is quite a spike! I wouldn't be happy with that for too long. I'm surprised you haven't hit fuel cut with a spike like that, but it may also be coming back down just in time to avoid it.

[Jay2525]

It could be my gauge not being 100% accurate nev, im was fuel ct kicks in coz before i took all gubbins out it ran ****e and was studdering, so take it that was fuel cut

[elnevio]

Fuel cut is an instant and sharp loss of power, quite violent really. If it was running poorly before because of the piping, then it could well have just been because of misreading of airflow, similar to having a boost leak.

[c0xxy]

is it hitting 1.5 bar every time?

i had mine set up with the pipe from the controller going straight to this t-piece slightly further down the red tipped pipe. this eliminates the factory boost solenoid from trying to bleed boost at the same time.

and yeah, fuel cuts a nasty sharp horrible thing, S#!te me self first time i felt it.

[Eurospec]

Get an evo scan log on it just to make sure it isnt knocking too.

Cheers,

Ben.

[Jay2525]

Turned it right down now, goes around 1.3 1.4 on a hard acceleration, then hangs at around 1.0. Weds when i set it up the air temp outside was hot so set it up with no fuel cut, last night 1am obviously colder outside hit fuel cut twice, and yer scarred sh*t out of me!! So turned it down slightly.
Yer ive heard of the them running it straight to t peice on car.
What would knock be then?

So now you know what fuel cut actually fuels like! :D You definitely know it if the first thing you think is, "Oh my God what have I just broken?!?".

[Jay2525]

Excactly what I thought Nev, or what did I just hit lol
