about dumping the excess from the wastegate, do i really need a dump tube?
my a/c lines will prob hate me if i dont get one, just let me know your thoughts and opinions.

 

yes, the wastegate blew a hole in my a/c line when I didn't have one.

Brad

 

my a/c line blew as well

 

nice and quick replys so its a must then

u guys have them now? is there a way i can custom it to go straigtht down to the ground, just a thought

 

mine is being shipped to me now...

 

Yes you can make a custon dumptube down, just get the flange that fits on the wastegate and then some piping and then cut and weld it to where you want it to point.

 

i think im gonna extend mine to just behind my front tire....., what do you guys think? think ill see any flames?

 

hmm will the 90 degree elbow work for the flange? stupid ? im pretty sure though
in matter of fact, can i just use that for the dump tube?

or should it be a little longer

 

I have mine routed to exit out the side of the front bumper on the driver's side.

 

just have it tapped into your down pipe....its the best thing to do.

 

Don't do that you can lose up to like 20+ hp. Best thing is have it routed somewhere under the car 18" or less from the wastegate. That way you won't lose any power or little.

 

thanks for the help guys...

 

If done right having the wastegate dumped into the downpipe wont cost you more than 3 or 4 HP, if that. So if you like it quiet, do that. Personally I just dump mine to the ground and call it a day.

 

I gots mines like dis:

 

That's what mine will look like soon...

 

have you noticed any boost creep with that setup? I think all the outside air rushing past it would cause the WG gas to have to fight its way out instead of just flowing out easily. A simple angled cut would stop boost creep... like how semi trucks have.

 

anyone know exactly how to do this? this is what i'm doing when i go turbo what kind of metal shielding would i need etc.. ?

oh yeah anyone know the legality about doing this in california? and noise levels?

Its illegal.

 

For those who asked for pics. Car's dirty (too cold outside to do a wash), but you get the idea.

 

Yes, you need a dump tube. Nobody likes 1600 degrees temp being dump inside their engine bay. The correct way is to route it into your exhaust. Nice and quiet, almost like factory.

 

God damn, 1600 degrees

My EGTs don't register half that!

 

Uhhhhh, are you sure your gauge isn't in celsius?

 

boostaholic, do you or anyone else have a pic of inside the engine bay so i can see how you routed the dump tube to come out the bumper?

 

Yes a pic from inside the engine bay would be helpful....but isn't that tube coming from the wastegate out to the bumper more than 18 inches?

 

when people say 18 inches with the dumptube they are referring to a closed loop system. supposively according to corky bell, the dump should be put 18 inches down the down pipe as to not interupt flow. but since this is dumping out the bumper it doesnt matter.
