Anyone with these installed:

I put these in yesterday, and i have noticed since installing i can hear the turbos whining (what i think it is) a little more now.

Always before, under WOT i could slightly hear them.
But under WOT now, and on over run (off the throttle from high speed), i can hear a whining noise sometimes. Doesnt sound bad or anything, but yeah just want to know if its normal.

I will try get a video of it and post it up, but does anyone know what im talking about?

Is there a chance that i installed them incorrectly?
Also, the car pretty much feels the same (drive wise). Boost goes to 1.1 Bar but even under WOT drops to about .8 Bar (also have IPD Plenum installed)

Thanks

 

Do you have the correct springs installed? The whine may be a leak somewhere.

 

What do you mean by correct springs?

I bought these from Vivid and they knew it was for Pan Turbo.

there are 3 pipes that come off the diverter valves.
2 larger pipes, and one really small pipe off the top.

I put them them in and after a day, the boost pressure under WOT went from the usual 1.2 down to 0.7 and I could feel the car didn't have the same kick it used too.

i was worried but then when I put the car back up on hoist, the valve on the drivers side, the little hose coming off the top of the valve had split.
So I cut the part off that split and then slid the hose back on.

Bingo go back to 1.2bar!
So amazing that a little split like that makes that much difference. And the hose itself is only like 2mm internal diameter. It's very very thin.

 

Do You know ratings of these springs? What setup should be installed for what ??

 

Not a clue.

Though i think the springs that were in mine were silver?

 

.... because you've got genuine product and me... one valve came event without logo; that's OK, but then what I see on aliexpress - exact setup !!! 20$ delivered to US ! vs 275$; and that seller is not providing springs ratings either (sorry couldn't find that DV on English version of aliexpress).
Proper companies providing ratings for springs and besides that they are standard ratings by colors, I just wanted to find out if anybody got the same Agency Power DV's like mine...
And one more thing: mine doesn't have 90 degree removable swivel connection for easy fitting, as the ones from aliexpress - another prove ......


P.S. about spings ratings:

one more question: yours were with 90 degree removable swivel connection for easy fitting or without ? I mean is it needed, this swivel connection ?

 

Does anyone have an install guide for the diverter valves. How easy to get to? Bumper off?

 

no you don’t need to remove the bumper, I would use google or YouTube to see installation.
