just got my new engine back in and I've done a few little jobs whilst it's been out. I had a standard recirc valve fitted but have removed it as I suspected it was passing under high boost. I was planning on blanking it off completely but after taking it for a run today I don't like the sound.

What recirculating valves are people running at around 2bar?

Thanks

 

Forge with a stiffer spring?

 

Hks ssqv

 

Can you get them as a recirculation instead of a vta?

 

Yes

 

gfb hybrid

 

Forge with stiffer spring

 

I was running a Forge recirc valve on my last setup Gaz, worked perfectly but sounded more like a vta valve as the noise of the air been dumped back into the inlet tract was pretty loud.

 

What colour spring did you have in it? Thanks

 

Wouldnt fit anything to my car that needed a spring to hold it shut under boost.

The ssqv works opposite to cheap forge stuff, boost actually holds the valve shut. So when running "man boost" it wont leak.

Theres a reason they are cobsiderably more expensive...

 

Thanks. I'd rather spend the money first time and get it right.

 

I purchased a complete spring kit from forge which i sold on here recently. I was using the blue spring and it worked fine

 

I deleted the dump valve when I went to 2bar

 

Turbosmart Plumb Back blow off valve would do the job, as advertised on Turbodynamics website, code TS-0205-1215/1216. It has a soft spring which responds quickly and works through equalistation of pressure, so it wouldn't matter how high the boost was as it's that which keeps it shut. £285.08 though.
