East to fit and you could up your boost to about 1.1-1.2 bar

Yes most definatley more bhp.
What year is the car? Different years had different fuel-cut points.

You'll only be able to go to 1 bar then.
The early ones had a low fuel-cut.

bang on olly 1.07bar which is 15.51psi i bought a very acurate gauge from where i work +or- 0.36psi used this to set mine up its now running 14.5-15 and doesnt cut but my god what a difference if 666 wants to borrow this gauge pm me

so is it wise to buy a boost controoler and up the boost yaself or si it worth taking it to a tuner to make sure everything is okay and let him do it?

As long as you don't interfere with the fuel-cut, it will be safe.
Its a factory failsafe to stop the boost getting to a point where it will cause damage.
Any amount under the boost cut has a fuel and ignition map to compensate.

if i wanted to run more boost say 1.1-1.2 bar i will have to buy a fuel cut defencer what else would need doing and would there be much difference in power and would it be safe at this level? what power should i be expecting with the boost upto 1.0bar,arc performance air box,hks exhaust with no center cat? also will the engine with this done to it still be able to take a good thrashing as i believe in driving my car hard alot(what its built for!) cheers your advice is much appreciated
as olly said dont mess with the fuel cut 1bar and those mods should get you 290-300bhp i gat 289 without boost turned up with only decat and panel filter and uprated fuel pump

so i take it its a very good idea to get a uprated fuel pump? how hard are these to fit? also what pump do u recomend? cheers guys

im a bit worried about running the car at 1.o bar boost is it gonna be safe running the upped boost or am i gonna be running to much boost and power for my pistons to take!??
1.0 bar of boost is not a lot for a Scoob. Get it on 1 bar then onto a rolling road to check fueling. Your ECU will handle the mapping. The rr will make sure your fueling is ok and fuel pump can handle the extra fuel needed. An uprated fuel pump is always a good idea when upping the boost. But best get it on RR to check it all out.

This is the type of thing the scoob lads use...:smile: Be sure to have a boost gauge to get the adjustments right.

At the RR day at AP, Boysey had low power and we popped a boost gauge on and found him boosting low he had this type of bleed valve fitted and we adjusted it to about the 1 bar mark... Big smile on Boysey's face on drive home...:hysterical: :hysterical: :hysterical:

:hysterical: :hysterical: i bet i remeber when i upped the boost on my mr2 turbo it just felt ballistic! im sure the scooby will feel awesome when done that extra boost will make it feel soo much better im sure do u do many rolling road meets on this site?
Ihave been to a few in the past year....:wink: Next one is Alan Jefferies early March.

have fitted the uprated pump just finished doing it seems to drive alot smoother and come into boost a bit earlier gonna fit the boost controller i bought had a really quick look and it looks like the pipes i have to connect it too are just metal! help!! as i have to tap into the wasgate feed dont i!?

well fitted and now removed it due to the fact all it did was overboost couldnt even get it to adjust to run lower boost if i winded it in or out it just kept well over the 1.0 bar cut out!! i fitted it after the elecronic boost sensor on the drivers side suspension strut on the pipe going to the actuator tried it both ways of fitment and both did the same! when i took the spring and ball out of the mechanism and put it back on thats the most success i had running near 1.0 bar fluctating in differnet gears but alot of boost cutting cumming in any ideas!! threw me im guessing there is something wrong with the device or did i put it in the wrong place? helpppppppppppp
Make sure the boost controller is round the right way. arrow pointing to actuator, these are tricky things to get right to start off with. if the boost controller is wound open fully you should have the same boost as normal then it should be wound in half a turn at a time untill you get the increase you requie.
Check the boost solinod for right conections two port boost is straight forward 3 port is Top - compressor/turbo Middle - actuator Bottom - Air Inlet from manifold
Also see PM I have sent you...

i have a two port tried it both way round with it fully out to the point where the turning head is about to fall out on both occasions is far too much boost! and when wound in all the way is the same also as u would expect even with it fully slacked off it still boosts too much! i cant see why it wont work!unless the spring is too hard for my boost settings

thats the mbc im using.
i have removed it now so cant take pics of it but i have described where i fitted it what makes it even weider is when i took the spring and ball out of the mbc and just put the screw piece back in it still over boosted but not half as bad some gears it didnt over boost but the fuel cut was still coming in!!!
Olly P
10-02-2006, 20:08 31
Thats the same one I had.
With no spring or ball in it you should have only seen actuator pressure (0.7ish bar) as theres nothing stopping the air going past.
If the unit is the wrong way round it will overboost all the time as the air pressure will push the ball into the hole and not allow any air to get past.
I got mine from ebay and it had SRP written on it, is it the same one?
Reason I ask is mine was a bitch to set-up as the spring was too hard which gave me no control over the boost, it was either all or nothing.
What I did was cut a loop off the spring and stretch it out to the same length.
This worked perfectly for quite some time and it then went on a Nissan 200sx which was a doddle to set up (because of the spring mod). It finally let go at a Haynes day when the end fell out and we lost the ball and spring.

It should be spliced into the pipe that comes from the actuator with the arrow pointing AWAY from it.

yep same one as mine thats what i thought i would have to do will cut a coil off the spring thanks alot mate will try it tomorrow and tell ya how it goes

Assuming you got new piping with the controller
find the pipe coming from the Turbo to the elcectronic controller on the wing,
and remove the from the turbo.
Next remove the other pipe from the Actuator to the Electronic controller on the wing.
Fit the new pipe in between the turbo and actuator, then find a suitable location to cut this pipe and insert the controller in here.
I would put a pipe between the two ports on the STD controller, this will prevent dirt and grime getting into the controller and F***ing it up. in case you should need to use it in the future.
I have fitted plenty of these. and they work well.

well wont work for my car!! i cut the spring eventually to only two coils left!! and it was still well over boosting!!!! so i have no idea whats going on and just to make it even better waste of money i have now lost the ball and spring yepee!!:lol: any ideas why this is happening?

mine doesnt look anything like that for a start i dont have a tap off to the turbo like that,mine was connected between the boost solenoid on my wing to the wastegate
Did you not read the link I sent you? Page 3 says...
But how does a MBC open the Wastegate when the desired boost level is obtained? First, lets look at where the MBC is installed. The MBC, which is essentially a valve with an adjustor on it, has two hoses. One hose is installed at a location that provides an accurate boost source. The location that provides an accurate boost source could be any number of places… a nipple on the compressor housing of the turbo, or another place in the intake system between the turbo and the intake manifold (basically, any location in the "charged" portion of the intake system). Different boost sources have different virtues, so turbo enthusiasts choose varying places to tap their boost source… we recommend that enthusiasts of the novice level follow the manufacturer's recommendation as to where to tap an accurate boost source. The other hose is installed at the Wastegate Actuator. In the picture below, the red arrow is pointing to the port on an actuator where the hose is attached. The Wastegate Actuator is the device that opens and closes the Wastegate, typically by means of an internal diaphragm, which cases an arm to move, which opens and closes the Wastegate.
You are trying to control boost with manual boost contoller that has already been controlled.. The boost solenoid should be bypassed.
Read Dereks post again...:rolleyes1:
If you do not have a tap on the turbo the inlet manifold should have the same pressure.

ah i see my bad sorry guys so i have to completly disconnect the one on my wing and tap into the inlet manifold sorry feel like i right idiot now!:lol: :lol:
Broxi
17-02-2006, 17:40 58
No do not tap into the inlet manifold, you should only do that if you are an advanced tuner, or your turbo does not have an accurate boost source. which it does.
look at the picture olly put up.
The pipe comes from the Turbo. (At present it will be connected to the solonoid on the wing.) take a pipe from the turbo. to tht MBC then from the MBC to the Actuator.
Simplest way would be to disconnect the solenoid on the wing and put the MBC in between the two. pipes you just removed.
then clock off the std solenoid, to prevent dirt etc getting in their.
