V-band Housings for EFR Turbos
 

Saw this and thought I would share, just in case it hasn't already been posted:

I hope these will fit the Tial v-band flanges, it would give me more turbo options in the future! It also will make the EFR turbos much shorter and easier to package I would think.

It will be a cool product, but it will add a lot of cost. They aren't going to have v band options that keep the internal wastegate, which is a nice feature of the efr.

But for the guys who already may have a complete EWG/tial vband kit, this may be a drop-in option to go BW EFR. I wouldn't necessarily want to redo my downpipe to fit the BW IWG Vband length.

My TiAL buddy says those housings are very tough to cast for some reason and they take a ton of R&D to get production ready. He's also a Garrett super-dealer so he may be biased.

May? :hustler:

In for results.

I desperately want an EFR, but dont want to drop the EWG setup...

The EFR's that we run are not getting the V-Band housings. We have called Treadstone multiple times to ask about it.

BUT IRRC Borg Warner themselves make a v band turbine for it. Only Indy car teams have them, and any questions I've asked them about it fell on deaf ears.

It seems stupid for them not to make different housing for retrofit applications available to the general public.

The turbos may be amazeballs, but the outlay for an entire new setup to suit puts them out of reach for most people.

What makes you say that? The outlay for a genuine garrett in the same relative size is between 800 and 1400, and they you still need to buy a bov and MAYBE and external wastegate and pay more for a mani and dp setup for that wastegate. The turbo itself is expensive, but that price includes a very well throughout waste gate and bpv system.

He's talking about the people who already have a well sorted EWG/Vband setup and may want to just swap out the turbo. For those people, if they want to go EFR, they have to redo their downpipe & plug their EWG port on the manifold. It's be nice to just swap & go, like you can do between Precision's vbands/tial's vbands/ATP's vband inlet T2's/Garrett's new vbands (I assume)/that treadstone piece, etc.

Now you have to outlay someone to shorten your downpipe and plug up the EWG dump if it was blended into the downpipe. Not a big deal for some but a deal breaker for others.

Ah I see what you mean. When I asked treadstone about the housing they told me that they wish they had made it in our size rather than the bigger size since they were seeing more demand for this after they did they already came out with the big housing.

If that is the case then you can only assume that unless they are idiots, they will make a smaller one and all will be right with the world.

They might be idiots, because in the same email they told me they had now plans to make one.

you just ruined my boner.

A bit of a necro, but I'm sure people will be interested.

I've just stumbled upon this and now I need July... It is probably why Treadstone stopped publicising the housings.

SONOFABITCH.


Oh well. But This means the small frame turbine housing is going to be getting made in both t2 sized v-band, and T4 twin scroll. So by calling the correct people I believe you'd be able to get a twin scroll 6758 if you wanted to. Though it looks like the Vband housing is going to be external wastegate. So I'm not too broken up about it coming out like a month after I'll have my turbo in.

am I reading this right?

IWG + v-band inlet + v-band outlet???11

I wish.

Looks like they're gonna make me decide between IWG and V-band inlet. Or just run ALLOFIT all the time :giggle:

Obviously EWG will be more difficult if I end up fabbing my own manifold, but v-bands will be easier to deal with...

I'd rather have TSE Inconel studs and the BW IWG than v-bands and a TiAL EWG.
