Please advise, I have had a look through previous threads and can't find the info I am after.
I got this info off a mate
My advises would be to stay away from a flow off valve as it will just cause more problems then give you any type of hp gain. This is because it will vent out air into the atmosphere that the engine ECU already calculated would go into the combustion camber so you might run to rich.
then this
Your mate is exactly right with what he is saying re the air being
calculated by the airflow meter. We can get around this by using a dump
valve that has a secondary spring to stop the piston opening at idle.
This is the main complaint with std dump valves as it lets in unmetered
air which makes the car run roughly or stall.
What would you all advise???
what type???
where from???
what about a fitting kit???
really it is for the sound not a bhp gain!!!!! :slap:
