OK couldn't find anything on here so going to ask what peoples opinions / logic is on this one.
What's best. Dump (to air) valve or recirc valve.
So the sound of an atmospheric dump valve is cool, but is it better for power to run a recirc valve as the boost is leaked back into the inlet pipe before the turbos and some of this air could of course head towards the turbos and keep them spinning a little??
What say you???
