Dump/recirc valves
Turbo Mini Forums

I'm not having much joy with the search function, so I'll ask some dim questions anyway...

With my blow-through supercharger setup, I'm going to need a vacuum operated pressure release valve between the supercharger and the throttle body.
1. Should this go before or after the intercooler ?

I don't really want a gert big Phhhsssshhhtt everytime I lift off, so i'm thinking recirc instead of dump valve.
2. Does the return of a recirc valve get plumbed in to the inlet tract before the 'charger, or to the exhaust pipe ?

Metric is for people who can't do fractions.

2. Between the charger inlet and air filter.

Hi,
I don't know if you can get recirc pressure release valves?
Cheers,
Gavin :)

1. Before the intercooler.

Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."
Stephen Hawking - "The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge."

Much as I thought - thanks chaps !

If the recirced air goes in before the 'charger, does that increase the boost further by effectively making it a two stage supercharger ?
More seriously, does the increased temperature affect anything - the intercooler will never get the charge back down to atmospheric temp, so the overall intake temp must go up a touch.
