Running standard engine, and standard DV........

what does "reversing the DV" mean.......and what affect does it have?

DIY job?

Experiences?

Cheers in advance......

 

[GaryM]

Yes its a DIY job and the only effect it had for me was a silly chirping noise - it lasted all of 5 minutes before being put back the normal way.

 

[Essex Escy]

so what does it mean?

why "chirping"?...obviously a bad thing......

and is that the stock DV?

 

[GaryM]

Its just the piston clanging against the body of my Forge DV007 which causes the "chirping" like noise.

 

[Essex Escy]

so not a stock DV then....

 

[GaryM]

No, a Forge DV007

i have a stock 710N fitteed in reverse on a chipped AGU. It is supposed to hold boost better this way round. It now makes a kind of double dumping noise from time to time.

Its an easy DIY job if you own some pliers and a spanner.

 

[Essex Escy]

do you literally just twist it upside down or what?

 

[blazedoobie]

The thin one stays in the top, and just swap the other two around on the DV itself.

Simple!

It is supposed to hold boost better this way round.

In the link you posted Forge stated that "Reversing the valve changes nothing in the way of the stiffeness of the valve or the amount of boost it will release or hold. Reversing the valve only allows the air to pass though the valve in a different manner."

so its the pipes you swap around, not the actual item itself?

 

[GaryM]

Yes its the pipes which leaves the DV sitting on its side.

There are two large pipes and one small pipe - leave the small one as it is and just swap the two large pipes over.

 

[blazedoobie]

gary-glad to see people read back. This should also help...

i believe, if memory serves, that the 710N in particular holds more boost when reversed.

However, not sure if any benefit other than a prolonged life span of DV, that there will be on a standard engine.

 

[Essex Escy]

ah ha!!....so just swap the large pipes around, and that "reversing" the DV........?

 

[blazedoobie]

pretty much!

 

[Essex Escy]

pretty much...........so no?

 

[GaryM]

Thats exactly what you do!!

 

[Essex Escy]

mind you, if you see my other DV thread......

my DV has just bust, so it'll be pointless anyway!

 

[Essex Escy]

if i reverse my DV.......could that stop my chattering?

 

[blazedoobie]

if its broke, no. go get a new one! Check the classifieds
