ok, this is a dumb question, but i just want to make sure. On a tial 35mm wastegate there are two 1/8 npt holes, one on top and one on the lower side. the way i figure it is the top hole is where u run the vaccume hose if you are using the certain ## spring inside the wastegate. And the hole on the side is where u run the vaccume hose if you have a boostcontroller, essentially bypassing the spring. Please let me know if im right or not, i bought it used and dont have the directions. Thanks

you have them switched

are you absolutely sure, the guy i bought it off of was running a boost controller, and the lower hole has the 1/8 fitting in it. Maybe he was running more boost than the spring ##. Im not sure, thanks for the reply

I was wondering the same thing when I put my boost controller on. I ended up putting the boost controller on the top fitting, and it works.

yeah you have it backwards... look on the instructions that came with the wastegate

yea, the top is for the boost controller

You have them switched.


FOR SURE!


You run a line from your intake mani to the side port of the wastegate.
This will only allow you to boost realative to the wastegate spring(i.e. .45 bar)
If you are using a MANUAL boost controler you can run it inline, from the side port to the manifold, but that's a different issue.

To my knowledge you only use the top port if you are using an electronic boost controller.


hope that helps, and watch your gauges!

also, the absolute pressure for an EBC can eb taken right off the compressor, or after the intercooler...ive seen both
