ok my friend gave me a wastegate but the spring is 25 lbs,can i use the wastegate with a boost contoll to lower the boost rate to 7lbs or i can t because the spring rate is to high.


pls dont flame i you cant understand it

 

you have to get a lower spring.. the spring controls the minimum pressure the w/g will open at

 

yea thats wat figured,so if i have a 9lbs spring wats th lowest and highest amount of boost the spring can handle

 

The lowest amount of boost will be 9psi. The highest amount of boost will depend on which wastegate you have.

 

so ben how much would it be if i ned a 7psi spring for my hks wastegate and i need a flange to connest it to mymanifold too

 

WHAT?? i thought the spring on the wastegate dictated the max amount of boost not the minimum.....so if i get a boost controller to boost less than the spring i need to get a new spring?

 

Yep, the spring dictates the MINIMUM boost amount of the wastegate. If you want to boost lower than the spring rating, you have to get a new softer spring. Peace.

 

So why bother with a spring?

 

Because he already has the friggen wastegate! What? You want him to buy a whole new wastegate? Now that would be foolish!

 

Well, when you start boosting high 20-30 psi. running a low psi spring will have more boost fluctuations. You can't really tell by the naked eye, but with data logging you can tell.

 

ok, say i want to boost 9 pounds max....but i want to boost 6 pounds most of the time....i have a boost controller....now should i just get the 6 pound spring?
