are these worth it? what do they do exactly?

cheers

 

[frank]

its a controlled leak in the actuator pipe andy, aint we covered this before ?

 

[Andy_S]

this the thing that sends boost down the pipe to actuator to open the wastegate? but i can stop it from sending boost down hence keeping wastegate closed and therefore get more boost?

 

[frank]

it spills/leaks a bit of the pressure out, so that you need more pressure to open the W/G

 

[Andy_S]

effectivley keeping wastegate shut so it spools more boost?

ok cheers i understand..

should i get one? lol

 

[frank]

aye, and only if you want to run more boost

 

[Andy_S]

ok

dump valve next haha.. where does that go?

ok

dump valve next haha.. where does that go?

reason i ask is i had a 207 gti which was turbo'd but that bov was mounted to side of turbo directly onto it.

 

[frank]

dont you have one fitted then andy ?

 

[Andy_S]

no frank. i get chatter back through air filter

 

[frank]

i think i wrecked my 1st TD05 by running no bov (shaft wear) mine has a diesel recirc valve atm, acting as a bov/dump, and just plumbed into the chargepipe

 

[Andy_S]

ok but uve got a small vac pipe coming off it where does that go?

 

[frank]

any vacuum source after the t/b mate, so that when you shut the throttle, it jerks the valve open

 

[Andy_S]

T/b = turbo or throttle body?

[Andy_S]

Ill have to look at diagrams. I don't get it lol

[frank]

if you want it to be neater and simpler, all your vacuums can go into a log andy (boost gauge/actuator pipe/fuel reg etc)

 

[Andy_S]

wheres that from? ive got a boost gauge

 

[frank]

wheres that from? ive got a boost gauge

google images mate

 

[Andy_S]

found them

although this is universal

So the pipe that goes to actuator i can put into this and wherever it was connected to i can connect to this to make a distrubutor..

think i will buy!

any unused ones i can just loop back into it

 

[frank]

a fat pipe goes from the inlet mani to the log, then tap off the log to whatever, but the boost controller is fitted to the actuator pipe only tho eh
4 bungs are included in that kit eh

 

[Andy_S]

yeah i was thinking that so out the log id take a pipe to the dashboard where i will mount the manual boost controller then take the pipe back to the engine bay and connect onto the actuator.



wooo bingo! im getting my head around it

 

[Andy_S]

this has confused me. now i thought u put the "vent into engine bay" bit to the actuator!???!?!?!

 

[frank]

its a controlled leak aint it andy, so the leak has to be vented somewhere, hisssssssss

 

[Andy_S]

ah ok i think i understand again lol.

when the boost controller is shut the boost does not escape and therefore forces the actuator to work. If i turn that controller to open the boost is leaked out into the engine bay and therefore not enough pressure to open the actuator?

so with a block just before the tee peice i have one hose from block to the tea piece and carry on the installation like that?


and the boost source is what ive got on intake pipe a hose coming off that going somewhere lol thats my input source yeah?

 

[Andy_S]

what else can u run from this apart from actuator pipe and boost gauge? you mentioned fuel regulator? what does that thing do? ive got two fuel pumps you see (one feeds the extra two injectors and other is in fuel tank)

just wondering if its worth buying one of those blocks

 

[frank]

the fuel reg should be on the end of the injector rail andy, unless an aftermarket one was fitted ?

 

[Andy_S]

<<<<-------------- this the pipe on bottom right which is attached to the fuel rail?

 

[frank]

looks like a stock reg on the bottom right of the 3rd pic andy

 

[Andy_S]

ok cheers
