Hi everyone, I just bought a Divorced and Transformable 3" Downpipe with Trial 44m wastegate for my Evo X, my car is near stock , just installed a hks cat-back. my question is do I have to hook up the air supply line for the trial 44mm wastegate? (external wastegate to atmosphere) if so, where should I hook up to? the instruction say's connect the air supply to the intake manifold before the throttle body, but i don't see where i can hook up a air supply to? i only see a big pipe coming from my intercooler.

thank you so much, i am new to here,
please help....

 

Do you mean tial?

 

It depends on what kind of boost controller you are running. If you are using a manual controller, the top port is vented and the bottom port runs to your boost controller. If you are running an electronic then both ports run to the selenoid with a T in place to the pressure source.

 

thank you for the reply
i am running stock boost

 

are u running both internal and external wastegate? if not, what are you going to do with the internal wastegate?

 

both

 

you need to tune it if your going to run the Tial external wastegate...

 

You can't run both. One or the other.

What I did, was take the pin out of the stock wastegate arm, and just let the flapper hang open.

 

i have the same dp with external dump and option to add a external wastegate. any benefit running external wastegate on the stock turbo?

 

You can hold more boost in the upper rpm range which means youll make more power up top.

 

how? please more detial ?

 

my car is stock , so i guess electronic boost controller>? T on the wasted gate from top port and side port then........another T on the selenoid where the pressure source?
