wastegate question
well i just got done putthow in my hx40 on today finally and i have a question.
how necesarry is the waste? should i just wire it shut or open whatever way it goes, or should i need to adjust it? ive never worked on a wastegate before so i dont really know what to do with it. i want to be able to get good boost out of it. by the way its an 18cm housing

The purpose of the wategate is to prevent your over-speeding and grenading the turbo. In order to set it correctly, you need to know the highest pressure within the turbo's MAP that can be produced safely without superheating the air in the process. Check with your turbo's manufacturer.

it is my understanding the wheel on a 40 is big enough that there is a risk of braking the shaft if u go much over 40 psi. ive got pods and a wickedly tuned pump and a 40 with a 14cm non wastegate housing and i only do like 35 psi. i seriously doubt ud ever have any trouble with that big a housing and no gate.

Not sure how many lbs/min I'm actually flowing but I can easily over 55 psi boost with my setup.
I HAD my gate disconnected when I first installed my HX40 with a 17cm3 housing and I connected it REAL quick !!
Now I'm limiting at 47 psi which I do not hit very often. I just don't trust stock head bolts with almost 340K on them.
