Astra Turbo Dump Valve Installation - standard OEM plenum

Time lapse installation of Dump Valve and intake pipes.

[chrispix]

P1dge Courtenay Sport installation guidelines don't recommend blanking off the original recirculation valve. The recirc valve does more than just release pressure on gear changes. On small turbos it can operate in the same way that a waste gate on the exhaust side does to control the pressure. Blocking the valve with the standard ecu map will likely throw an error.

Now this is a good video to show how to do installation. really fun to watch also :D

lol I love the sound of the cars whizzing past in the background.

Quick question: I have a Fiat Bravo 1.4 Turbo (tuned with 200bhp) it has a dump valve as standard but I think it's leaking a bit, what can you expect from a Fiat eh? :P but was just wondering if replacing the dump valve with a different make will require as much work as in this video or whether I can just take the dump valve off and fling the new one in place?

Do you have any videos if removing the recirculation valve on the turbo and fitting a blanking plate?/

Promotes flow away from the turbo when you close the throttle. It continues to draw cool air through the intercooler and should prevent the turbo from slowing down.

Disadvantage is you are wasting cool air and the computer doesn't know where it's gone. Sometimes causing the mixture to momentarily run rich and in some instances causes a backfire.

@1308lee
it makes your car sound nice, and lets the compressed air out of the turbo :)

@chrispix I have written a couple of questions that a well educated bloke in the area of Astra turbo mechanics may have the answers to. Car running really badly spluttering and loss of power. Will only drive at barely above idle revs otherwise engine light appears flashing and car shutters even worse sounding like an out of tune 60's beetle( not normal obviously) any idea of what it could be?? I kno it's kind of broad! BTW enjoyed your vids. Thnx m8

This is so freeking cool i new there would be a vid here.. cheers buddy thats great stuff..!! a vid is so much better than reading instructions..!! thanks a million..!! ;o)

[lkj]

the main advantage is that it sounds freaking cool

[Baynham]

so aswell as a sweet hissing sound you get a nice pop from the exhaust? doesnt sound like a disadvantage to me :P

[edvinkalda]

Can I do the same on Zafira opc with z20let since the engine is same? Is there any suggestions about bov choice? I was thinking about HKS ssqv4 but now Im abit confused.

[ULSTERISBRITISH]

I have installed Rss ind kit. would this cause any differences in the install ? also does the dump valve have any negative impact on performance? my last 5 cars have been turbos . a4, a3, Leon cuppa and scirocco tsi. I had a dump valve on the a4 and later removed it after endless reports that the dump valves on the tfsi engines caused performance reduction? I don't really know enough about the astra j vxr engine to even hazard a guess if it would reduce performance, ??

Hi ajneeves, pipes are from Courtenay sport. About £100 for the standard plenum kit. :)

Do you have a problem with a check or. Something? I eveven Heard ir you put another valve the ecu send Message.

Sorry for my english im latín

hello, chris, how much Milimeter the dump valve hose? 4mm or 3mm? And the little "T"piece? 3mm or 4mm?
thank you

timelapse? lol i can tell when your just going really fast. :P

great vid!

@AdzNSV
1. Get in the car with the ignition off.
2. Press the throttle pedal AND brake pedal down and hold them down.
3. Turn the ignition key to position 1 and then onto position 2.
4. The EML will begin to flash, it should flash 10 times initially and then pause then flash a certain ammount of times, pause, flash a few times again etc etc

10 x flash (pause) 1 x flash (pause) 7 x flash (pause) 10 x flash (pause) = 0 1 7 0 which would be: P0170 Then enter the code in google

@chrispix i have after market bov on my sri turbo astra but it turns my engine light on. kno how to make it no turn it on?

[AdzNSV]

BTW really overdue for a service and timing belt change if that helps you diagnose. Pls answer if you or anybody knows and has the time.

[chrispix]

They probably changed the intercooler or something as well as changing the hoses. I find it hard to believe you could get a 30hp power gain from just replacing a hose.

Zero KW at the wheels seems like an accurate assumption from my butt dyno ;)

People install these hoses to customise the appearance of their engine bay and/or to add a dump valve.
There is a chance of affecting throttle response, thus creating a possible improvement. But it's more about looks I think :)
