* TURBOSMART * Internal Wastegate

[caveman21]

Just wunderin what peoples thoughts were on the turbosmart internal wastegate ? Would it be worth the money to upgrade or is it a wastegage of money lol

This uses boost pressure to actuate. The current setup is vacuum. Looks like you will need a boost controller aswell to control the pressure.
It would be interesting to see if it actually works as claimed.

Iam installing a boost control valve with my dawes valve like a lot of people do but do mean that the turbosmart internal wastegate would need one just to control the boost presure to the wastegate ? My experiance with this stuff is nill.

It basically makes the turbo work off boost, not vacume..

Lots of pros and cons..
Cost, tunability, remote parts stock if needed, 'v' ease of setup, set and forget etc etc..

I personally went dawes / tillix with a needle valve.
Why? In the end it's basically exactly the same just still vacume instead of boost, yet far cheaper...

Being a variable vane turbo, which from my knowledge, works better with a controlled spool up rate, I can't see how this actuator would benefit as it only controls boost pressure and you would lose the ability to control spool up rate. I'm happy to be proven wrong, as I haven't heard a lot at all, if anything, about this setup. Apart from it uses boost not vacuum to control boost. so if you do got this way, your dawes and needle valve will become useless and a conventional boost control valve, like the turbosmart controller is what will be needed.

Thanks for the info MUDSKI and BIGGUWESTY i think i will just stick with the dawes and boost control valve as i have these already to go and it seems to be the best way to go
for me .

Works the same, just uses pressure instead. So when there is no pressure the vanes are closed allowing fast spool up the obviously boost pressure increases so then the actuator starts to open the vanes. Much of a muchness to a dawes and needle valve although once setup a pressure control system can be fine tuned much better than vacuum.

Thanks for the input Mat. It would be great to see if anyone has one of these fitted to see if its worth the coin. If the setup is easy etc etc. I think UFI or one of those mobs are doing bigger or better turbos for these 3ltrs now.

Diesel smart have something similar on the market using pressure instead of vacuum. It has mixed reviews. Turbosmart do tend to make some good gear though and they are australian I believe.

Gturbo have been doing turbos for the crd patrols for quite a while now. UFI are starting to more and more as well. A few guys out there now running 130rwkw daily and a few up at 160rwkw. Even a few di motors starting to push some decent figures

Here is one (not Turbosmart) fitted to my 2009 CRD.
When my 3L got tuned and dynoed to a Unichip setup, they tuned it to a regular needle and dawes valve setup and weren't happy. Then they fitted this Wastegate set at 19PSI and the car went great after it! The best I've had that car go after that was fitted.
Now the downside is, apparently, the turbo was working much more flat out compared to usual as the vanes are open, and once a 19PSI threshold is reached the wastegate opened up so thats how it works o pressure.
That's all I know about it. Car went 10 x better then with any needle and dawes setting i've ever had.
