I came across the new V band turbine housings on Tial's site , They are available for the GT 42 and 45 and are only available in 1.0 a/r for now, anyone using them yet ? apart from the obvious (ease of mounting and positioning along with less weight ) , what are the pros and cons ?

 

I believe the price I was quoted for a GT42R hot side last year was around $4,500. Enough said

 

My buddy called on one and it was only a few hundred bucks more, this was a couple weeks ago btw.

 

dam that looks sweet but $4500 god dam

 

Something doesnt sound right there ! My local dealer said that they are about $100 more than an original housing , putting them in the $400 range , and yes you can buy the housings separately . I also believe that a turbo can be bought without the turbine housing .

 

Exactly what I was told . Maybe ill have to change it up again this winter, dammit!

 

I know hks uses this setup on there big turbos, t51r spl etc

But Isn't the standard T4 or T6 fully divided turbine housing with a well matched divided manifold more efficient specially on a 2 rotor ?

And this is better for hard to place turbos ? and maybe some weight and ease of taking off or on

Over all I would think the 13b still is better off with a fully divided manifold to divided turbine housing, no ?

 

I think you guys are confusing the v band option with the s/s turbine housing option.

 

Arent the SS housings Vband on the inlet?

 

I've been waiting for months for TiAL to send me two of their gt30's. I was told that they are working out all the problems before they release any. I might recieve the housings early to mock up a manifold, can't wait- these look awesome. Ordered two bovs, v60 wastegate and couplers from them already. They advertised these in several mags a few months ago as available. Still waiting.

 

Those are perfect for a parallel twin turbo setup. I looked in to those about 6 months ago. My setup would have true dual exhaust though.

 

I have them but they are very slow to getting them up and going. It took forever to get ahold of a few. I needed them for mock up purposes.

 

Sean, how is the quality of the overall product?

 

Sean do you have the housing for the GT45? , is it 1.0 or larger a/r , are you willing to sell it to me and get another for yourself ?


This is true , but there are a lot of people out there who run undivided manifolds and housings and have no problem with spool , The manifold I would make would still be fully divided until the turbos inlet though, so I doubt I'd see any appreciable loss , and I am also going with a bb turbo so that should help improve the response too.

 

i think it will help more for placement and easy of assembly and disassembly sp? alos weight being a key factor i think flow especally for a 2 rotor devided is the way to go

 

From what I understand-

If you do a long runner manifold with a proper collector the undivided is great.

If you have a short manifold the divided will help spool significantly.

The round entrance is especially nice for flow on the V-band housings. This set-up could use one of these turbos

 

I know john shepard and his awd dsm uses that Tial style of turbine housing and he is in the 7's with it....

 

My supplier was also told "off the record" that those housings flow quite a bit more than the equivalent size in the "traditional" housing style , the 1.0 a/r housing on the GT45R is said to be good for up to 1000 ponies !
