Turbosmart wastegate installation

[EcoMax]

Orderd the turbosmart wastegate. Installing it requires the turbo heat shield to be removed, anyone have any experience with the process? I can see the top 2 bolts is there more to it? And any tips on setting the actuator arm?

Should have two bolts on the bottom as well. Just keep removing bolts until it comes off, it is pretty straight forward.

Setting the pre-load, just set it to 1/4" shorter than the factory wastegate.

I suggest a re-tune with this if you have the ability to do so, if not don't go anymore preload than 1/4".

I put one on my Fiesta ST, worked out pretty slick. Blog post below.

Thanks for the information, i will post my gain results if any as soon as i get it installed.

Need help please

I got the heat shield loose, I jut can't figure out how to get it out of there. There was 1 hex bolt on the bottom on the side to the rear. That was a little awkward getting out but doable. Can anyone offer any help on getting the heat shield out once it is loose?

Never mind, I got it.... and it will never be the same.. HAHA. I just bent and forced it out of there!

For anyone else that does this, I didn't see a better way than bending the heat shield straighter to slide it out. The good news is it went beck in much better than I expected.

Adam if you see this, my factory wastegate was at about 3/8" preload. I couldn't even set the Turbosmart wastegate with as much. I had to turn the end on the rod until it bottomed out and just got 1/4" preload out of it. So actually a little less than the stock one. I'm just saying since you will be doing my tune in a couple days. :clap2:

Good info, need to install mine after I get back from Bowling Green.

Please set per the instructions and only make fine adjustments.
It does not require anywhere near the OEM actuators pre-load by design.

Thanks for the info! I'm a rookie, how can I tell if it is too much or too little preload?

Since this made for the EBM does it need adjusting or is it set to the correct length out of the box?

It definitely needed adjusting. It comes without the rod end screwed onto the arm.

I've been trying to learn about turbos, very new to me. I'm a V8 supercharger guy. It looks like the wastegate opens from pressure to prevent overboost allowing exhaust to be diverted from the turbine. If that's correct, I'm assuming this preload will hold the wastegate open that amount (e.g. 1/4") allowing a small amount of exhaust gas to always slip past the turbine but gradually open further as the spring rate is approached. Does that sound about right? If so, would the indication of the preload being too much be the turbo not building full desired boost?

By the way, if anyone knows any good reading, I'd really appreciate the reference.

Kind of , Ideally you would want a wastegate set that opens just before your max boost and does not allow creep or spikes in the process .
Thats not realistic though , so you have the wastegate valve preloaded enough so anything before the set pressure it is held closed (remember the exhaust manifold side has high pressure to trying to push that valve open).

So you want least preload that holds valve close and when it does open you don't get boost spike. If say you cranked the preload to say a lot it would take a lot to overcome pressure and the amount valve opens, hence boost spikes .
Depending on pressure and how good the bracket is (some flex) i used to set preload to like 3/16 to 1/4" or so . best to go by proven results, mine are generic (what I used to use first) before testing.

There was a book long ago turbochargers by Hugh Maclnnes .

Thats an overall of turbo's, very old, not sure if still in print but goes over many area's of turbo . sizing, intercooling, compound ,wastegates etc .
The applications of course are all old, but basic theory is still valid .

See what others post, I have not looked into books in long time.

Edkiefer, THANKS for the reply and information! That makes a lot of sense. I was thinking incorrectly that the preload holds the wastegate open that amount and I couldn't understand why. So if I understand you correctly, the preload is an amount of force pre-applied to hold the wastegate closed. That would make it so all of the exhaust is used to spool up the turbine until you get up to desired boost pressure. Sound right?

Thanks for the book recommendation! I'd like to first understand the fundamentals and components involved, it sounds like that book would be perfect. Later I can build on advantages of twin vs. single etc.

Have anyone able to put on a blanket without putting alot of stress on the Wastegate?

Yes, the pre-load is making sure enough pressure is holding the wastegate valve closed until preset value is reached .

Here, you might like reading this site first for general engine/turbo stuff .
It gives brief but basic overview on various sections of vehicle .

Hope its ok to post, I have nothing to do with it .
