Guys,
Looking to run around 330bhp -350-bhp when mapped on my WRX.

It is possible to run with out a DV, reason I am asking is I have one on the std IC at the moment and hate the whoosh noise! I have decent Sti IC on its way to me soon but doesn't have the standard DV, so will it be OK to go with the chatter and run without it and blank it off?

 

Depends on what turbo you have, more so if you are still running a MAF

 

All depends on what turbo your planning to use

 

Looking at using the Sc36 from SClinic and stillrunning the MAF

 

Running a maf will mean you need a recirc dv won't it?

I run 500+ with a boost controller in line with the dv so it chatters on low boost (less than 2 bar) and high boost it dumps but I am on a map sensor

 

lol low boost 2 bar

 

Yeah it does put a smile on my face when I see the boost gauge light up and go round the maximum :L

 

Less than 2 bar is low boost!? This can't be on a Subaru!

 

Yes on my classic scoob mate.

 

Did it break?? Who mapped it?? What was the spec??

Only reason I ask is because the highest I have heard somebody running was 1.8bar! And even then there was a bit of a worry that the standard headbolts wouldn't be happy.

 

Am running 2.75 on high boost?

 

That's a serious amount of boost!

 

SC36 not reccomended to run DV less as sleeve bearing.

 

Cheers dude. Any one selling a standard DV? 53 plate Sti cooler

 

That turbo would be fine to run without a DV in my opinion, nothing to do with the sleeve bearing, all about quality of components.

The reverberations onto the MAF would be the issue

 

they are not recommended to run with no dump valve, yes it does have to do with the bearings, the SC36/38/40 use sleave bearings and would be less robust then the bigger SC42/SC46 with the garrett BB core which is stronger.

 

Think ill stick to a dv as it came with one out the factory.
Does anyone have a used one for sale?

 

I run DV less and my car makes more noise now than it did before, When lifting off full boost it makes a right scream...
