Re: OBX turbos
Im going external. I need to do this because of the way I want to clock the compressor. The wastegate canister will be where I want the turbo to point. Going external on the crossover. I think Im going to like the sound of an external dump. Should sound like an air compressor at full boost

Re: OBX turbos
Have you had your wastegate done like this before? When I had my PTE-52 turbo on my truck it had a external wastegate mounted on the cross over. When at full booste and it was venting it was loud and droning sounding. I remember the dump tube also being a real pain to make so it was not dumping hot exhaust gas onto something it would melt. I've since had the wastegate mounted on the top of theh downpipe kind of next to the turbo. I wouldn't recommend doing it this way.

Re: OBX turbos
I totally agree with NASTETy92! I have my WG on the cross over and it is annoying as hell! It sounds like a cracked header. I'm building my new turbo setup to tie the WG back into the down pipe. All I need now is a few more hundred miles on the new engine and I'll be ready to mount up my pt6776RSP!!:lol:

Re: OBX turbos
Anyone have video or audio on how this sounds?
I got my refund from OBX today. Seems like a good company to work with atleast. The mitsu 25g is on its way.

Re: OBX turbos
It sounds like A$$.:tdown:
Better to plumb it back into your exhaust system,,,,or have it's own separate muffler & exhaust system for the wastegate..:2cents:

Re: OBX turbos
Thats pretty close. Like a hupty going down the freeway with a broke ass exhaust at the cat..... I put a dump tube on mine and it helped some:lol:

Re: OBX turbos
If you guys would just stop stomping on it everywhere you drive you would not have to worry about the wastegate opening up and sounding like a$$ :rotf:

Re: OBX turbos
I thought so too at first. Then drive the truck like that for a week or two. Mine sounded louder than those cars and deeper.
Good luck,

Re: OBX turbos
that sounds close. The problem with my truck is that the Waller 57mm stock upgrade turbo spools so fast the way I had it tuned that the WG was open a lot!!!
Personal I would rather hear the turbo and not the WG! If you like it do it!! the boost control was much better, just be prepared to be annoyed with it after a while!!
To each his own!!

Re: OBX turbos
OK thanks guys. I dont really see a way around it now. The turbo I have is not internally gated. I bought a spacer for a wastegate and thats not going to work. There were some clearance issues.

Re: OBX turbos
What kind of clearance issues did you run into? I'm just wandering because I am planning to use a spacer too.
Thanks

Re: OBX turbos
The top of the wastegate will hit the turbo compressor if faced forward. If the wastegate is faced to the back it might rub on the manifolds or suspention. A way around this would be to make a pipe come off the spacer and then to the external wastegate. Also on the flange its theaded on both ends. You would will need to take the studs out of the manifolds to bolt it on. You can't use nuts beause there is no room between the 38mm flange and the t3 flange. It can work but you need to mess around with removing the exhaust manifold studs. The T3 spacer with 38mm wastegate flange also does not line up the greatest with the T3 stock exhuast manifold.
