Wastges: Tial 38Mm Mvs Vs Turbosmat 45Mm Hypergate

[stocker]

looking for some feed back/opinions on these wastegates................as ive always run the old school garrett 32mm and 42mm gates............never used tial or turbosmart gates before........i have 2 38mm mvs gates and 2 45mm hypergates

any info be a real help

im not interested in sizes i know how gate work the smalller the gate the less gas it let 'sso theres more gas to spin the turbine ie high boost and big gate let out more gas for less turbine speed ie low boost ...........im more interested how they perform,hold boost,longevity of the gate in question,issues with the two brands etc

[DVS JEZ]

Both are very high quality gates. I havent ha a gate "wear out" only the cheap evay gates are a little dodgy as the valves dont seat 100% and theres too much play in the valve guide

Not sure bout turbosmart but the Tial allows coolant to run thru the top, does anyone run coolant thru or not worth it?

Ive been told all the Tials are just cheaply made in china? is this right or are they made in US?

[stocker]

i was planning on running the coolant if i end up using the tials

hi you find the real tials are us made but there are a whole heap of china tial knock off getting about.................before you buy a tial gate get the s/n and email it ti tial they tell you if its legit or not ...............but funny thing is turbosmart are made in china or what ever,yrs ago turbosmart use to have a hughe yearly sale of 2nds at wetherill park..........but there moved there manufacturing plants o/s

wtf happened there?

[AngryRB]

lol, well personally i think the Tial looks the goods, i have a 44mm Tial and its a large unit, looks pretty hardcore compared to turbo smart. I havnt seen it work yet though and a newbee with this

[stocker]

i sold my tial 38mm gates i go buy some tial 44mm cause they use same flange as the turbosmart and do some back to back r&d/testing

[stocker]

any of you guys with the tial gates run the coolant thru them.............and do you think it is actually needed

[scotty nm35]

There is no need unless its mounted close to the turbo or manifold. Even then you can shield it rather than run the coolant lines. Its for race use mainly.

[WMDC35]

I'm running 38mm tial v band, no complaints

[femno]

Yep, we have a Tial 38mm running straight off a turbo housing in a low mount application...which would get mega hot compared to having it off the manifold at the collector. It runs the coolant through it and the boost curve is straighter than a ruler.

Under racing conditions where everything gets super hot and the metals and welding are under most strain, the coolant helps lower temps down and prolong the life of the wastegate. The diaphram's life will be extended, as rubber perishes from heat over time.

I prefer TIAL gates as weve had ONE genuine TS gate jam. Theyre both good designs and nice and compact. The feature of the coolant cooling is favourable if youre racing it, but whether you have room for the lines (assuming twin scroll since youre using 2) or not is another thing to consider.

[stocker]

i flog off the turbosmart 45mm gates once they come and just go the tial 44mm mvr...............got plently of fittings ans braided hose to go around

[AngryRB]

where would you tap into the coolant for the Tial, would you put a T piece in the turbo coolant line or somwhere else?

[stocker]

i got a 2jzgte aristo champ i would run them off the top water neck i would just get some alloy weld on 3/8th bungs to feed the gates the cool coolant and feed them back in to the alloy radiator to cool the colant exiting the gates opinions ?

[Bsa]

You can run it that way but might look nicer having them hooked up to turbo feeds less clutter

[zebra]

from memory OP is going TD06's

so the factory water feeds/returns will just be sitting there doing nothing anyway

[Bsa]

He got some hks units I think been chatting to Dave over the weeks

[stocker]

i got some hks 2jzgte twin turbo manifolds with t3 flanges welded to them works out good for my twin td06's........is that a bad idea to feed the hot coolant out of the gates into the turbo'sor vise versa blake...............ive hidden the fusebox in the clovebox etc,deleted alot of stuff..........blake is going to be welding me in a custom tunnel
