I don't think anyone will or even can answer that question until one of these has been tested.

Wastegate placement was a valid concern. It's more about exhaust pressure than velocity or direction of flow, especially in this very low volume manifold. There are dozens and dozens of examples from very sought after manifold manufacturers doing this same thing, we don't expect it to be an issue and truth is, if that's the case, we solve the problem and move on, it will only effect a small part of our production process.

We've finalized the details and attributes that will be offered for the Side Mount EFR Manifold (although nothing is set in stone) and it's live on the site. The first 4 are already sold, there goes our attempt to stock them - so we've prepared for full on production starting next week.

Click Here for the product page

For those who would like to know, the down pipe is going to be a sub $400 solution.

I see there is an internal wastegate. Is that still a v-band?

Yes, a number of the EFR series are offered in an internally gated configuration:

...in the 7xxx series, correct? I've not seen a 6x58 V-band + IWG other than what BW teased us with at SEMA a couple years ago.

Right. It's in the catalog as a housing option, I've never been able to order one so we don't stock it.

Wow. Definitely interested in this. Any plans for downpipes as well?


Edit: Whoops. Reading is fundamental.

Someone asked about how sharp of a turn we're expecting for the DP, here you are:

That's not insane. Very nice

Still interested in MC clearance though.

This turned out to be a really nice, short downpipe configuration, especially for how high the turbo appears to be... as for MC clearance, it's at least a couple of inches, on this car specifically however the bottom brake line is awkwardly bent towards the down pipe for some reason.

Wow that looks great. Amazing how much space is saved by not having a big 5 bolt flange to connect the two.

Is it possible to change the location of the MC? As you said it shouldn't be an issue, and it is a very simple job to cover the MC with a heat shield, would just be a cool solution to mount it farther towards the drivers side.

Man getting the angle correct on the downpipe sure looks like a time consuming job and a lot of wasted pipe getting it just right.

AWESOME clock by the way!

Moving the master cylinder would move the brake pedal too right...?

You could do it without moving the pedal at all. You could put it on a pivot/angled bracket like Ford did on the pre 1974 "early" Bronco. Not the best picture ever, but it gets the idea across.

Looks like it would be a PITA to fabricate and probably not woth the effort.

Or just get a heatshield or heat wrap like everyone else does. No use reinventing the wheel.

You know how many zany ideas I've had. Usually get all amped up to do it then I realize how much unnecessary work it would take for something that has a tiny advantage.

I must be getting lazy...or old...either way, ain't nobody got time for that!
