What connects to the wastegate

Silly question but what pipe is meant to connect to the wastegate and where does it come from??

Cheers

 

the pipe on the wastegate should go to the n75 valve if you have one failing that you can run a pipe straight to the t/b for instant boost lol

 

which engine is it on?

the wastegate is part of the turbine housing (usually, unless its an external wastegate)

the wastegate it connected to a shaft, which has the actuator on the end.. the actuator moves the shaft and opens/closes the wastegate

the actuator is conntected to a vac hose, after that, it depends on the car

 

Sorry its the 16vt this is the turbo and waste gate in question cheers

 

the wastegate controls the boost level, it depends on the setup of your engine. ive seen a lot of turbos where the wastegate has a vac hose the connects to the compressor housing and "senses" boost that way

 

i'd agree with that. it's basically measuring boost. so when the boost reaches a level greater than the spring in the wastegate actuator can hold it'll start to open the wastegate thus preventing the boost getting any higher.

a boost controll or bleed vale would bleed off air in this hose to cheat the actuator into thinking it's seeing less boost.

 

Ahh so on the old one the wastegate was connected to the other pipe comming off the turbo




next question what do i use now that the new turbo aint got a outlet for the wastegate

Cheers for the info

 

Add a nipple to at near the start of the boost pipe. Advise to place well before the throttle.

 

so on the boost pipe I will have this end, Where can I get a nipple from ? cheers

 

LMA do them nipples, or merlin motorsport, i saved having to drill mine by tapping onto the silcone hose , with a special hose take off at the boost pipe,

 

20 bloody ell they aint cheap

so what are you going to control boost/engine with?
aftermarket ecu... which should have its own "n75" kind of control output to dial in boost when mapping it

 

not a clue to be honest, Its still running k-jet too

 

actuator only pressure then or bleed valve or external ebc - but you will need to control fueling & spark to suit

standalone is a very good idea @ this juncture me thinks

 

Thanks Bill,

This is the old setup Not a clue what the box does i presume thats the electronic boost controler? There is a switch a 2nd heater button this is the "extra boost" button.

What alternatives have I got at the moment on a budget? non aftermarket ecu at this stage? How would a manual boost controler work?

Cheers

if old TT kit then I think there was a crude driver for 5th injector for additional fueling and some means of clockwork ign advance control.

 

ahh, Shall I invest in a manual boost controller from ebay

 

i think its best to get the non bleed type.
