my bleed valve has three legs, i bought it 2nd hand and this is it...

does anyone know why one of the legs is blocked off? It has a grub screw in it! Whats the best way to have it in-car?

The places to connect it to i have is two places on the actuator. Someone on here said to leave one of them on the actuator unblocked and just use the other one.

If i do that, how do i connect up my bleed valve?

as far as i know there are 2 ways to install a bleed valve (Dave will correct me!)

1 the 2 angled stubs on the bleed valve go inline with the pipe from the turbo to the actuator. the centre stub goes out of the car as the bled off air comes out here, you will need to remove the screw from the stub first!

option 2 fit a "T" piece in the pipe from the turbo to the actuator and run to the centre stub. leave the other one blocked and run the other to outside the car.

Extra

if you block the outlet pipe with a solenoid valve you can switch from standard boost to what ever you set the bleed valve to in the flick of a switch. (no more twist and hope when racing chavs of the lights)

also keep the pipes as short as possible

dont forget to fit a flow regulator inline feebs

this is to go in the signal line from the turbo side to the bleed valve

Does this mean i have to set the boost on just the actuator arm?

well fit a fitting in the pressure side from the turbo

oh is that all the pipe that comes out of a T3 turbo does? Is it just the boost that the turbo is producing? does this mean i can just take this pressure from the plenum outlet?

Am i right in thinking that just under my air intake on my turbo, its something to do with that small round thing, dont know waht it is now the engines in but i think there was a screw there. Is that where there should be something? Look just under the air intake...

If it is, theres nothing i can do now :( Is it ok to set my boost on my actuator?

yes i think so, if your thinkinbg what im thinking, you need to get that screw out and find a pipe fitting that, and then link it to the actuator

if your planning on running high boost in the future you may want to make the hole larger with a drill as i had to do this

Argh wish i knew :(

im not planning on running high boost, just something arround 9 or 10 psi

i went round to jimmys last nigth and the only option i can see is to take the signal from the plenum to the actuator, does anyone see why this wouldent work as effectivly as it would from the compressor housing?

i have never tried it but it should work. the only possible problems could be fluctuating boost pressure due to a delayed reaction caused by the air between the turbo and plenum compressing. however as there is no intercooler this possible/theoretical problem should not occur.

i see in the photos that it is a T2 actuator. i use the T2 but with a T3 actuator, i could give you a load of bull about the T3 actuator being better but i never bothered investigating how the T2 actuator was fitted. my point is i see a pipe already fitted to the actuator, and wondered where does the other end go? if this is going to the plenum then what are you doing with the other pipe on the actuator?

yeah nowhere at the moment.

Ill block one of the outlets on the actuator, and connect my bleed valve inline with the plenum then.

Im interested in your idea about the T3 actuator though! if it makes a difference i might try that!

jimmy dont block the other outlet on the actuator, it need to go to atmosphere so that the diaphragm can move.

i used the T3 actuator for several reasons.

1 i had some in the garden shed
2 i know the operating pressure of the T3 one
3 i had no info on pumbing etc for the T2 one
4 i had to make a bracket in any case so chose the T3 actator

good luck and if you have other questions just ask as normal. its better to ask and get the car running well, than to find a mistake the hard way

This is infact the best place to take the signal from, especially if you have an intercooler.
