Of course it's a safe way of adjusting boost. All he's doing is removing the notoriously unreliable amal valve. Some of the people above have just shown their lack of knowledge about how things work. But I reckon they book their car in for a spark plug change, too so fair play to that...

If you run a hose straight from the compressor housing to the actuator your car will hardly boost at all. Be lucky if it does 2 - 3 PSI so I don't see why it should be dangerous.

However, if you decide to up the boost by including a bleed valve later on you have to make sure that the fuel mixture is still OK.



I set all my cars up by myself. I have 3 engines in spare so I couldn't care less about a meltdown. Haven't needed any of the 3 in 4 years now though so I must do something right.
