As for those twin scroll turbine housings from ATP , have a look inside them if possible because some people reckon they're a bit dodgy looking . I've no idea who makes them and no ones said they have Garrett markings on them so anyone's guess .

A .

just received myne yesterday. has ATP cast onto the housing so i assume its made by them. some of the machining leaves a little to be desired and the outlet area looks like a choke point but hopefully it'll work a lot better than the IW housing i have at the moment.

some shitty phone pics. thats a 3" v band flange sitting on both sides to give you an idea of the small diameter inside, very different to the garrett housings which are a smooth and progressive opening from the turbine size to the flange size as in the first pic.

found one. anything in particular you want to see? took shitloads of photos anyway. one more thing i noticed is theres no machined area around the bolt holes for a nut to seat, might have to get into it with the grinder.

Is that a twin scroll internally gated turbine housing?

In regards to other questions asked here, the 1.06a/r T4 twin scroll GT3076Rs spool AWESOME in all the cases I have seen - quicker than the .82a/r T3 housing when used with a proper T4 TS manifold. It'd go very very nicely!

Hell, a GT3582R with a 1.06a/r T4 Twin scroll housing spools similar to a .82a/r T3 GT3076 :D

When your fit the CHRA you might want to check how far the CHRA bolts protrude into the volute. Try and grind them back so they are flush with the inner wall if you can.

This is a tip that Full-Race mentions on their web page with regard to the .78 twin scroll housing....it might apply to the 1.06 housing as well.

That's good to hear...

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.

      Duncan's V37.......race car?

      By Duncan · Posted

      Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
