Jellybean Posted January 16, 2017 Share Posted January 16, 2017 Anybody come across any dyno plots? From what I can see all Tial Vband housings are Single scroll and Garrett do a twin Scroll Vband housing I cannot find any twin Scroll Vband setups to compare Link to comment Share on other sites More sharing options...
JackyBoi Posted January 16, 2017 Share Posted January 16, 2017 I think vband manifolds are supposed to spool slightly faster, but I've never seen any dyno graphs relating to this Link to comment Share on other sites More sharing options...
j_jza80 Posted January 16, 2017 Share Posted January 16, 2017 (edited) Why would it make any difference? Surely the only advantage of v band is the ease of removal? And possibly a potentially better seal? Edited January 16, 2017 by j_jza80 (see edit history) Link to comment Share on other sites More sharing options...
Frank Bullitt Posted January 16, 2017 Share Posted January 16, 2017 (edited) I think vband manifolds are supposed to spool slightly faster, but I've never seen any dyno graphs relating to this Are you not getting mixed up between single and twin scroll?

JackyBoi Posted January 16, 2017 Share Posted January 16, 2017 Are you not getting mixed up between single and twin scroll? No, the boys at 6boost said their vband's spool faster than T4 twin scroll Link to comment Share on other sites More sharing options...
Jellybean Posted January 16, 2017 Author Share Posted January 16, 2017 I think vband manifolds are supposed to spool slightly faster, but I've never seen any dyno graphs relating to this This was my understanding too, but lack of Vband configurations or the need to buy an additional housing like the Tial curtailed demand Link to comment Share on other sites More sharing options...

Style Posted November 11, 2017 Share Posted November 11, 2017 Anyone find out anymore info on this? I’m wondering if V-Band is going to be the new way forward if it outperforms a T4 twin scroll setup in spooling faster. I can’t think how it would make a difference tbh but wanted to check anyway.

j_jza80 Posted November 11, 2017 Share Posted November 11, 2017 IMO any performance loss/gain over a conventional flange (t3/t4 etc) will be marginal, the advantages and disadvantages lie in the way both types fit and seal, vband being easier to fit and remove, and having a more consistent seal with no need for a potentially troublesome gasket, but a little bulkier so may be more difficult to fit in some instances. You would need a decent divided V band manifold in order to use one of those turbos though. Link to comment Share on other sites More sharing options...

You would need a decent divided V band manifold in order to use one of those turbos though. Its the manifolds I’m looking into with Black Friday approaching y’see. There’s no price difference between a T4 twin scroll and a V-band (single scroll) one. Obviously that means needing a turbo to match so I was wanting to know if it would be worth my while to convert to V-band and sell my T4 Link to comment Share on other sites More sharing options...
Wez Posted November 12, 2017 Share Posted November 12, 2017 If your T4 setup is divided / twin scroll and the new V band setup isn't then I would say stick with what you got Link to comment Share on other sites More sharing options...
