What Should I Do With This Hose?

[4drftn]

iever since i have owned my car i have always had this hose off the turbo... i think it may have been hooked up to the actulator, anyways.... would it be best to block this off? if so what is the best way?... or should i leave it how it is?

cheers

If you don't have a connection onto the wastegate actuator, then you are lucky you still have an engine! But I think that hose is connected directly to the compressor housing, so it will be venting boost straight out to atmosphere.

is that bad? should i block this off?

[4drftn]

should it be connected to something???

[4drftn]

will it cause any long time effects? or damage?

Without a connection to the actuator, the wastegate never gets a signal to open. So the turbo just keeps building boost, until the engine spits 6 pistons out through the bonnet of the car.

With that hose venting boost to atmosphere, the wastegate doesn't get the full boost signal (it's acting like a bleed valve), so you risk getting same result as above.

In the worst case, that hose should be plugged (a small bolt is sufficient). In the best case, it probably should be connected to the wastegate (or boost controller).

oh ok, i think i will block it off... has anyone ellse had this drama? i just wanna do it right... sounds like it can be rather expensive...

iv blocked it off with a bolt, just before i did i started the car to see if any air came out or anything... nothing so i gave it a few short revs and could feel air coming out... i take it its still the right thing to block it off yeah??

have you got an external wastegate?

if so, block it off, it not, plug that pipe back into the inlet or plenum, there should be another line for it :S

The guy above is right, you could overboost without it connected :S

And not in the cool way like in the movies

The line basically builds up pressure and a certain PSI, if it's R32 - round 9-12psi it opens the wastegate up so your engine doesn't recieve too much boost :S

[4drftn]

its an r33, well i have the boost controller hooked up to the actuator which would stop it from over boost... wouldnt it???

[skybarge]

Is the boost controller tee'd into the actuator and the return line to the inlet somewhere?

if so yeah, should be fine just block that other line off, you'll be losing power from it otherwise
