Stop My Bov From Fluttering

[letemlaf]

I have recently got my hands on a blitz bov from a subaru legacy.

obviously it didnt fit so i made a 'go between' flange out of mild steel to make it bolt on where the standard bov used to fit.

It was quiet dirty when i first got it so i cleaned out all the gunk and lubricated it again but when i installed it onto the car it makes a flutter at any rpm and any boost.

im guessing the valve isnt working correctly and wondering if theres anything i can do to make it work as it should?

thanks!

btw ive attached a pic of the bov, what type of blitz valve is this?

[paulr33]

change back to the stock bov

why would u want to change?

[cerci]

i ust 2 have that ezact same bov

sold it and i just use my standard bov wit new intercooler piping

paulr33, i have nothin other than my stock bov on my rb25, there must be another 1 out there that sits in its place that does a better job

[paulr33]

theres nothing wrong with the stock bov

[cerci]

yea i know there is nothing wrong but im sure there is a better 1 to with hold all the extra power u have given ur car

so no need 2 change to a brand name?

I wanted to change the sound and i like the blitz, no other reason, i can always change back if nessesary.

Any ideas how to fix this one?

soften the spring setting if there is any adjustment left.

yeah adjust the bov if you want to make that 'pshh' sound.but honestly if you have a stock one keep it or if you dont. dont use a bov.

dont want to get defected all because of some little anodised gadget in your engine bay that makes turbo noise.

[PANGES]

if it's able to stiffen or soften and it's already at the most soft it can get, then the bov is possibly broken and not opening correctly.

[letemlaf]

yeah i guess just use the standard valve

just out of interest... what model blitz valve is this?

[letemlaf]

i just noticed that the spring is about 6 times as long as the hks sequential, could this mean that the spring is for high boost applications, and seeings im only running 10psi it is way too strong for the application?

First see if you can back off the bolt on top to the loose setting.I'd even say cut a coil or 2 and then see how it goes.

Clean the brass plunger free of any grease/lube as these only cause the plunger to drag.
