Watercooled Wastegates

Anyone running a water cooled wastegate?

 

I've got a Tial 44mm MVR and I'm looking for suggestions on how to plumb the waterlines into it. The turbo I'm using (GT30) is also water cooled and I've already used the front of the block to feed the water to the turbo and I've returned it to the bottom of the rad. So I'm limited to what options I have left.

I have the same wastegate I never bothered running the water lines I figured it must be for extreme track days.two years later no problems.i guess if u wanted to u could put a t piece on the inlet rad hose seen them on ebay for next to note they are like a alloy block with a tapped hole for a sensor or water feed u must av seen them then run ur return into ur return of ur turbo?

i wouldnt over complicate your setup. You dont need to run them water cooled under the vast majority of circumstances. I never bothered on mine personally either.

I guess if u was making 1000hp and u was always on the wastegate then stuff might get hot but for a daily 300-400hp motor then im 100% certain you shouldn't need to bother pal.

I would love to avoid running the waterlines as mentioned it over complicates things, however saying that; Tial recommend fitting the water line if the downpipe/exhaust manifold comes close to the top hat of the wastegate and this is the case with my setup unfortunetley

These Tial WGs have worked well without the extra 'water-cooling' for years, so I personally don't think it is required in a majority of setups. But as you have said, if the WG top-hat is in a very hot and precarious position then it would be beneficial to run it lest you damage the WG diaphragm from the extreme heat.

How's it going stranger! :)

 

Yeh this is the thing, leave the waterlines and risk damaging the diaphragm or make use of the waterlines and be safe. I'm not going to be running massive power but I know that the engine bay temps will get very hot.

How you doing! I've been very busy. I only ever come on to reply to PMs and then have a 10 minute scroll through the tech sections lol

 

You could always heat wrap or ceramic coat the manifold. Ceramic coating is excellent! Wrapping is good too but I've seen some heat-wraps cause minor surface rust because they can lock in moisture...

 

On the other hand... Ceramic coating looks cool and can be done in various colours B)

If youre worried about the wastegate sticking with not running water lines, just use boost protect in the map when you get it tuned.

@4dvti I have thought about ceramic coating but thats something for the future, I guess its not a cheap process either?

@Mick I need to look into boost protect and how that works but it could be an option i guess.

Boost protect is easy to setup. You just enter in the table the maximum psi you want the engine to have. If it goes above that threshold, the limiter will kick in. RE water lines, just link the wastegate in on the return line from the turbo.

That's some hot water! Not what I'd use.

I think Mick meant join the wastegate water return to the turbo turbo return?

There is a spare waterport on the back of the skunk2 manifold, which i have blocked off. Would that be good to use for the water feed?

If you have the option to run water lines to the WG then run them. Just "T" off a small hose for the supply. It will help extend the life of the WG. Especially if it has a poor cool air supply.

Zirotec is good for coating, just to put it out there...
