Yes. Edge is getting it handled.

I just looked up the turbo, any reason you wanted the IWG over an EWG?

 

[Enki]

The EFR IWG flows better than most larger EWG. Why wouldn't I?
Pics of my turbo attached; you'll notice that WG flow is pretty much a straight shot from the turbo inlet flange to the downpipe when the WGA is fully open; this means the amount of flow for this size flapper is superior to a 90 degree turbulent shitstorm that is a standard EWG. As it sits, even with the T25 flange, this turbo will flow in excess of 500 to the wheels on a genwon 3.

When I grow up I wanna be just like you with all your knowledge

 

[Enki]

That's easy. Just read more.

When I grow up I want to have your modding budget

That's easy; live with your parents and work from home.

Lol no. As far as I know CPE doesn't make a T25 flange mani.

Probably not. But I don't know all of the EFR hotside options either (if any). The EM sort-of looks cast in that pic, so I wasn't sure its type

Resistance to being pulled is futile!

The EM looks bad ass. Can shed more details?

 

[Enki]

Oh, it is.

Basically this one with 2000 degree silver/titanium coating:

Edit: It comes pre-gasket matched to our head as well.
Edit2: It also has a stock flange option and will work with TMICs:

I see full-race kit only offered till 7163. Any idea why it can't go any larger? I guess it was due to limited space near firewall to fit in large EFR housing.

 

[Enki]

Won't fit. All A-Frame EFRs (up to 7163) come with a shorty WGA bracket so you can actually install it. If it didn't, you can't get it in the car with the engine installed.

Edit:
Second gen cars and MS6 can probably top mount a larger turbo, but that would require a custom manifold and downpipe to be made (downpipe is easy, since It's just a simple vband outlet).

If you do that, get one twin scroll and at least a 7670, which I think is ideal for our cars from a response to top end perspective; the 8374 will be a little laggy and it will be hard to not blow the tires off in 3rd (maybe even 4th) unless MS6.

IMO I think the 8374 would perform awesome on our cars with a twinscroll setup. My 362 is pretty much the same size and I don't have that magical titanium turbine wheel and am still spooled up a bit north of 3500RPM.

Do you have any concerns about surge?

 

[Enki]

On the 7163?

Edit: I tested this on Matchbot and the consensus is that I can run a 15 psi spring no problem at 2500 RPM. From there, 20 PSI @ 3k and 25 @ 4k, then a whopping 40 PSI @ 5k resulting in 475 WTQ and 450 WHP. Yahtzee.

 

[AYOUSTIN]

Yes on your new setup. In my experience matchbot gives very typical on paper answers, doesn't really reflect real world results all that much. I'd bet you could run more boost than that at a lower RPM, that is a good baseline though. Also, I haven't looked at the comp map for the 7163 but 40psi seems pretty far towards the top of map, no?

 

[Enki]

Basically just below the surge line all the way up.

awesome progress and very sexy pics!

How was that your first post over here? You need to catch up noob.

It's Dano, the man-o! Anyways, back on topic... You going to tune for this now, Enki, and just redo the whole process after you de-stroke?

I don't know what you mean...The car is on jack stands, and the wiring harness is in a box on my bed so there's literally no way I could tune it right now.
