XS Wastgate Question.


Tricky-Ricky

Recommended Posts

Ideally i want a 0.7 or 0.8 bar spring if they are available, Jamie, is there only one type of greddy wastegate?

 

Dunno mate, i changed when i was running in the new engine as the Greddy one was to high, with the xs one i was only getting 0.5bar with the nut wound right out, iirc the xs wastegate is not adjustable though.

There's 3 types of XS wastegate I know of, 38mm, 42mmm and 50mm. The one I had was the 42mm and it came with the 1 bar spring, which one do you have Ricky?

 

And Jamie, mine was not adjustable.

 

XS do a 60mm WG also.

My mate has a 0.7 bar spring for a xs power 50mm wastegate.

I will ask him if he wants to get rid of it as it was a spare for his.

 

Thanks mate that could be handy, the reason i want a low spring pressure (assuming an external behaves the same way as an actuator internal one) is that i want to run a quite low boost setting, .6 to .8 bar and then set up the boost controller for two or three boost settings.
