Which is a better plan. As usual, Im fighting parts that dont fit. I bolted on the Tial WG and it doesnt come close to lining up to the pipe that runs to the DP. Is there any difference venting to atmosphere or back to the exhaust?

Atomsphere is LOUDER, I know that one. You will know when it opens thats a plus.

OPEN

You can't hear my TC76 spooling anyway so atleast the WG makes some turbo related noise

CHRISPY

Just noise level, no other issue with running it open

Im also thinking that itll help my little 38mm keep the boost down if theres no restriction..

CHRISPY

If the gate is undersized you'll likely get boost creep no matter what unfortunately.

True, I think I am having that issue right now.

Also, as for dumped versus not, where is your WG located and what is your planned exhaust? With my WG dumped underneath on the passenger side and my open exhaust I cannot hear it.

I would also think that you could pick up a bit of power if you have a dumped WG instead of routing it into the dowpipe.

FWIW, I can hear my turbo spooling up very clearly (whistling noise).

the size of your downpipe and exhaust basically grow when you dump the wastegate to atmosphere.

its louder, but you know that the WG opens.

My exhaust is a Hooker CB, but Ill add a cutout down the road...

Here is my car on a short run, my exhaust exit just under the rear passenger seat (right where most cutouts do)

Personally, even if I did not have an open DP I would still run a dumped WG because I like to get max power.

I run mine back into the exhaust, I run mine in at an angle that "May" actually enhance exhaust flow. I'd rather listen to the 70,000rpm turbo over a dumped Wastegate.

What exhaust do you run on your car Ryan?

I only have a 12" down pipe off the turbo, no muffler and the WG's are dumped to the atmosphere. You can hear the WG's over the exhaust and turbo...


I've got a vid. that you can hear when thay open, give it a min. and the car will show up....

the smoke was from needing a oil restrictor, that is taken care of now and doesn't smoke now.

Thats what Im thinkin'. When the WG opens, it would seem like a big exhaust leak coming from a 1.5" pipe. On my kit, it plumbs back in at a 90* to the DP though Im going to fix it and see what it does.

My exhaust Runs like this, the down pipe comes out on the drivers side of the engine at the rear, then goes just behind the transmission and crosses over to meet up with the normal catback. The wastegate is on the passenger's side comes out facing down then turns straight back. It then merges with the rest of the exhaust system at a angle that when the wastegate opens, its flow creates an eductor type of suction on the down pipe. Now, IN THEORY, this may enhance total system flow but its untested definatively.

Here is a S78 at 6psi with a turbosmart 50mm gate open to atmosphere.

Hmm, interesting. What diameter is your WG pipe that meets up with the normal exhaust? Maybe I will try something like this

S78 rocks.....

Ryan K

I "think" its 1.5" or 1.75".

If its a 38mm, then its a 1.5".
