[s-cars] DahlBack Racing BYpass Valve

[Frederic L'Huillier]

Hi,

The reason I am asking is that I have heard many opiniona on aftermarket
bypass valves.
I heard a very loud Forge Bypas valve last night on a 5 cylinders
engine. I don't know what is the gain in term of performance but in term
of noise, it is definitely impressive ! ! !

On related matter, is this possible to have the same noise as the S1
ByPass Valve ?
I suppose the amount of noise is related to the amount of air released
due to the size of the Turbo ???

Regards,
Frederic

IIRC, You get better throttle response, 50HP (only if
you put the stickers on) and a lighter wallet.  ;-)

FWIW, all of the aftermarket valves are the same, give
or take.  Bailey, Forge, TXS, Turbosmart, etc, no real performance gain
in my book, other than what you may be losing from a leaky stock valve.
