Sorry to make you guys scroll. I know how annoying it can be.

Lots of fun reading tonight guys https://www.nopistons.com/forums/pub...IR#>/smile.png



I would want a HD valve in the turbo precontrol line though correct as my primary seems to be ok?



And...for my next question:



Would a popoff valve not also solve the spike problem ?

(and yes...i know...is NOT boost control but a safety device etc etc etc).



And if it would indirectly...would it still be prudent to use the HD valve in the turbo precontrol line as well as the popoff valve (for insurance and wastegate failure) or would that be overkill?

Y9ur car already has a blow off and pop off valve on it. Do you not like the stock parts?





I would put the boost controller on the line to the pre control.

Stock BOV is fine. No problem there! (although it would be nice to have a sweet sounding one but priorities demand I keep the car on the road and healthy)



What stock POV? Did I miss something?



I'll look into to the HD mod. BUT....what about the POV plus the HD mod? Overkill? Redundant? Or 2 different purposes?



Anyone?

I checked today.



You will need to put the boost controller into both lines to tune out the boost creep. Yes there is a stock pop off but they call it the charge relief valve. It's the same damn thing though. If you like that loud <<<pshhht>>> sound when you let off the boost. Then take the lines from the charge relief and the blow off valve that go to the back of the airbox off completly. Don't worry they only blow air out and not back in so you need not filter these two.



The charge relief valve is attached to the top of the "y" pipe if you needa reference. Also it is almost identical to the blow off valve. The one on the top and closer to the firewall..

Thanks for the updated info!

Lots of work ahead for lil ole me.

The CRV is not a pop-off valve. It is only open below 4500 rpm to vent boost from the secondary turbo.



A smaller oriface in the precontrol line should help remove the spike. DO NOT REMOVE THE PILL!!! It will make your spike worse.



If you use the Home Depot valve for precontrol, shut it all the way first (you should see a big dip) then SLOWLY open it and check you prespool/transition/spike. Minute changes in the valve position make big changes in prespool.



Good luck.
