Anyone know whether the new TiAl SS housings will be equivalent to a T4 or a T6 or something else altogether?

Zero? Cris? anyone?

thanks

There approprietly sized for the turbo charger application. In other words, they are the same in size as the turbine they are replacing. So your question would have to be turbocharger specific (EX: GT28, GT30, GT35, Gt40 etc. etc.).

I admit that I am in no way a know it all. . .but I don't think that is correct.

I have a gt42. . . with a T6 turbine housing (1.01 A/R), however that is a not how they tend to come http://www.turbobygarrett.com/turbob...2_731376_2.htm.

The dimensions associated with the CHRA are all the same, only the housing is different. I fail to see (not calling you wrong, just saying that I must misunderstand) how they could accurately provide me with a housing that is being that my turbo has more than one option for turbine housing size. A 1.01 A/R T4 is not the same as a 1.01 A/R T6.

Ok, I'll be more specific. They are sized to replace the most POPULAR sized turbines that come on the turbo chargers, not specialty sizes. Example would be T4 sized turbines for GT35R's. We in the rotary community use these frequently, but theres very little others who use them. The biggest uses are the standard T3 sized which still yet come in many A/R values. So, I'm just speculating here, Tial will size these as a T3, yet if you notice they offer 3 A/R values for every turbo. All or most of the turbo's have one family sized foot print stock, theres just a couple (Gt35R, GT42) that are offered in two family turbine housing sizes. Hense "So your question would have to be turbocharger specific". A clear answer would not to ask in a forum, but asking Tial themselves. Like I said, this is speculation on my part so take my answer with a grain of salt. i concluded with this by reading the link I posted.

I had a good long discussion with them and to put it short they are not a T3 nor a T4 or T6 they are turbine specific. Kinda think of them as frame specific. IE a T6 is not a T4 even though they can fit on the same 42R. So a 1.0 tial is not equavilent to a 1.0 T3 or a 1.0 T4 if that makes sense. I asked specifically because as Mike stated, we prefer the larger T4 1.0 to the smaller T3 1.0 and I didn't want to be stepping down in size if I run them. Hope that helps some.

Minor revival. . .

Zero,
In your discussion with them, did they provide any dimensions on the housing? Specifically, the area (or radius) of the housing inlet. If we had that, we could make an assessment as to whether or not using them would be in fact stepping down.

(ignoring the rounded edges, treating the orifice as a perfect square, undivided)
Flange Size : Square Area : Required TiAl Radius for Equal Area
T3 : ~4.6 sq. in. : ~1.2 in.
T4 : ~5.9 sq. in. : ~1.4 in.
T6 : ~9.2 sq. in. : ~1.7 in.

bumping this thead..What are the dimensions for the vband, meaning the dimeter of the inlet?? I need to start making my manifold and I need an idea of what to order.

just startn

iTrader: (33)

I been wondering about this. i read about them in a magazine and i didnt really understand and i still dont understand about these things. can this thread get some detail about them. they look good when their on a car and say tial thats about all im getting. sorry

It is a V band inlet compared to the traditional t3/t4/t6 frames that are common. These are made of SS with makes them lighter than the original cast iron and they also have better flow.

There cast stainless steel. So, you get great looks that wont rust. Extreme heat resistance. Really light weight compaired to standard cast iron. Easy to rotate vband inlet which is super easy to take the turbo off and/or replace. Never needs gaskets. The inlet scroll has much smoother finish when compaired to cast. hmm the down sides??? Not fully divided. If you have an existing manifold, it wont work due to v-band, and making an adaptor will move the turbo making your downpipe and intake/intercooler tubes move as well.

Really? Have they got back to you on this? I have been pounding away with them on turbine flow and can get no real answer out of them. This is with asking specific comparisons on specific frames and specific platforms.(Not just rotary either) I even in the end said lets make it simple do you have any way to compare turbine maps I'll do the work. I got nothing in return. I am making a few setups with the housings regardless but I feel I am being forced to since no-one there seems to want to answer questions about the characteristics of something they designed.

anyone with any software that allows them to compare the inlet area?



Pictured is the GT42/45 turbine housing, in what looks like a T4 frame to me. For this housing they are only offering a 1.00 A/R as of right now, although they indicate that a 1.15 is in the works as is a 1.xx (whatever that means).

Just what I was told. My tuner has a buddy that used to work for tial during the design process for these housings. He was told they flow better. I have no number comparisons or anything along those lines..just hearsay which isnt very good, i know. Anyways, Sean can you order these in the 1.0 for the 42r? I called ATP and they are currently out of stock but they say they have some coming in.

I was looking at that pic today and thought about trying to compare the inlets. The inlet areas look to be pretty close to the same amount of area.

Just went ahead and did some crappy editing. It will give you a rough idea. But the Tial inlet does appear to be larger.

Well after talking with them I can't get definative answers and while I can't expect them to have tested them on every possible setup. I would at least like a idea of what to compare to. The only answer I get is they flow better. I don't get anything about comparisons in relation to frame. Yes I can probably have a housing here for you rather quickly. But I would need to be paid upfront.

these couldn't POSSIBLY work with a p-trim T4 wheel could they?

Out of the box I don't see how. Could you make it work? Sure how much you want to spend?

Inlet flange fits a 2.75" tube. perfectly. ID of flange is 2.625"

They are rather nice housings. I have a few sitting here (30,42,45s)now to start mocking up kits.(already have orders for!!) Mainly 42R and 20B kits will be upgraded to this. My guess they will flow rather well, only throwing them on a car before and after would we know for sure how much.

And one of those kits are mine! Canīt wait to see it sitting in my engine bay that has been empty for 3 years! See how much it makes with E85, PFC, twinpower, AEM P&H box, 4x1680 2x850. Think the problem, if there is any, would be the twinpower not giving enough spark. Anyway canīt wait to see that lovely Tial housing on my GT42r kit!

Looks sharp.

For your 13B gt42r kits, do you normally go with a T4 or a T6 turbine housing?

My concern is that TiAl says, and likely correctly, that their new housing flows better than the regular garrett housing, and as I'm sure you're well aware, the default garrett supplied housing is a T4. So TiAl is not making a comparison to the T6 housing, which is of interest to many, myself for sure.

Please please please keep us apprised of your findings in this endeavor.

I agree it will flow better than the T4, I'm not sure about the T6 which is what I've always used. But the nice thing is it flows better than the T4 without the size penalty of the T6. I do know after weighing it it weighs 10lbs lighter than the T4 housing and 12lbs lighter than the T6. So it's kinda of a happy medium at this point without hard numbers.

How will spool be effected with the Tial housing being undivided and the other housings being divided?
