Psssh, I have two of them! :P

How does that system actually work? Because looking at it, I actually thought it was a better (i.e, far easier to hide) system than Scotty's "external gate on housing" setup.

Then again, why not just simply make the dump diameter that size?

This isn't an external gate, it's a crappy exhaust bleed off gate.

If your exhaust is building that much pressure then it's simply not flowing enough, and as I would explain to a customer, 3 inch is too small for 400kw. I guess if you researched a little Tao you would have known that, but hey perhaps the carbon monoxide is doing it's job. :P

How are your steering rack boots?

Yes, but an exhaust bleed off gate and an external wastegate/screamer really has the same effect ultimately, which is to reduce pressure in the dump/immediately after the turbo.

This seeeeems like it's easier to hide, easier to setup, etc. Then again, maybe the answer is to run a comically large dump pipe. 3in into 6in on a 45 regree angle anyone?

Would have been nice to see how well my setup actually ran, if it would you know, actually run.

Tao, how about instead of a weird spring flap thing, you put an external gate on it. Yeah. An internal gate turbo, then your weird dump then an external gate on the dump. Gate city.

Use boost applied to bottom port to open the extra external gate. Then can have a solenoid to keep it shut if you want to boost past an rbt or heaps cops.

I might just patent that idea.

More gates equals more better.

Get a JJR bellmouth dump pipe and venom high flow cat

Dump pipes / cats make no different to the noise, only flow. I have the above on the standard catback and it is as quiet as a mouse.

Get a custom catback exhaust made up. DO NOT SKIMP on the catback. My cheap catback is deafening at 2000 RPM which is where a street car spends 90% of its time. It's quieter when you are at 3000+, which is the opposite of what it should be. I went back to the standard catback and the shit exhaust is currently in my garage waiting for me to figure out how to get rid of it (probably to scrap metal recycler).

      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.
