Hi,
as many of you know I have a 1987 C900 Aero.  I think my Saab dump valve is
playing up again.  Considering a Bailey or Forge replacement.

I personally love the Pfft sound of an atmospheric dump valve, but I accept
that to many here it would be heresy to fit one.

However, I need two opinions:-

1  Bailey or Forge motorsport.  Anyone tried a Bailey valve?  They do seem
to be cheaper, but still look pretty solid, even if Forge is industry
standard.

2  Atmos or Recirc?  Forget the sound issue, I like it and (no offence
intended here) I don't care whether you do or don't.  The important thing is
does an atmospheric reduce lag, as claimed by one trader at the SOC
National.  (I doubt it)  Also bearing in mind I have an Air Mass Meter,
(which some of you know to be a sore point!)  will an atmospheric cause me
problems?  Read on saabcentral that it can cause stalling problems as the
air measured by the AMM is lost to atmosphere.

Your opinions and help as ever are always appreciated.

Al
