Boost Reference Line!

[SLYLNE]

Where the arrow is, there is a nozzle sorta thing. that leads to the actuator. This isnt how my turbo looks like atm, there is no hose connected.

what does that do? i have seen on some 33 turbos, that has been blocked off?

thanks..

that, my friend, is simply a nipple that lets air flow from the compressor to the wastegate

they are on r32 turbo's but not on r33 turbo's

that picture is a turbo from an r32... (it says 16v10... r33 turbo's say 45v1 or thereabouts)

on the r33 they have a nipple in the intercooler piping somewhere that goes to the wastegate instead

hope that helps,

isnt that the boost reference line on the turbo???? feel free to correct me if im wrong

[WazR32GTSt]

call it what you wish..

its not there on rb25's

is tells the wastegate what the boost is so that the wastegate knows if it should open or not

[SLYLNE]

yeh, ur right..i dun have it..when i checked again.

is tells the wastegate what the boost is so that the wastegate knows if it should open or not

i guess in a way, it could possibly be more accurate than having the 'nipple' on the cooler piping? because its directly from the turbo?

[SLYLNE]

thanks again guys for your help!!

cheers

i have the nipple there on my RB25 turbo (purely because its on an R32 and i had the hole drilled and the nipple fitted, as the 'cooler piping doesn't have the provision for the boost feed, and its more accurate/quicker at the turbo)

[WazR32GTSt]

depends how you look at it...

at the turbo you get exactly the pressure of the intake at the turbo

after the intercooler, and you get it to measure exactly how much boost ets to the engine after the pressure loss of the intercooler...

i think the latter is more beneficial myself personally

Nope you'll find you get alot more responce when it is closest to the compressor housing. Try it and see.

[SLYLNE]

so i drill a nipple on the turbo? :s..

think ill pass on that..btw rumour or not, the r32 wastegate actuator when fitted onto r33 turbo..does boost to 10psi without any boost cuts or spikes..

smooth and solid boost right through out the rev range

i fitted it to mine, i found it runs around 9psi
