Default OK guys...here a quick one for ya. (ATP Dump tube Q)

The wastegate that opens and closes the flapper has 2 nipples on it. The way I have my set up now is as follows. Turbo-->boost controller--> turbo wastegate. Now w/dump tube, Turbo--->boost controller (with a T to run a signal to the dump tube wastegate after the boost controller-->from other side of T to the turbo wastegate). I drove the car tonight and the dump tube isn't opening up. Should I run the line from the BC -->dump tube--> from the other nipple on dumptube to turbo wastegate???

Some insight would be coo..thanks guys.

Default stupid question, have you tested the dump tube before installing it?

do you have any idea how much boost it requires to open?

If the other nipple isn't capped on the dump tube, it won't open right? Is the other nipple capped?

Default Thats what logic says..this is WHY I'm asking this question..

It makes sense in my mind...figured I'd ask. Why else would it have 2 nipples on it???

Default I was thinking of running a line from the BC to the dump tube and --->

and from the other nipple on the dump tube back up into the engine bay to the turbo wastegate and make a complete circ.

Default blow into the tube to the dump tube

can you blow through it? I'm wondering if you push boost out of the dump tube back to the wastegate, if it will affect boost. You might have to adjust the MBC if you are going through the dump tube.

Default Hmm..I'll call ATP tomorrow on my lunch and bug the sh*t outta them

I want this thing to work. The FMIC I finished makes a world of difference (it's all of 54degrees out right now.) It pulls like it's on 100 octane...absolutly nuts!

Now..if I can get the DT to open..should be good for 25-30hp more!!
