Yes, it does. I would be happy with 15psi at 3K rpm which from some twin scroll dyno charts I've seen is possible.


Yes, this is my only concern. That the IWG will not be able to keep up. I did speak with the full race guys who have held the twin scroll IWG turbos in their hands though. I asked them if there was a lot of material around the IWG if it needed to be ported. They said YES so even if it does creep, hopefully it can be fixed.




Are you going to get a twinscroll?

I agree. If the turbo is sized correctly for your motor size/power goals/etc...you should see some nice gains in spool, especially with your bigger motor.

Yeah, I was thinking the same thing. But after reading that chart and info that was posted on the Full-Race face book page, I think I am pretty much sold on it. The turbo they tested has a 42mm internal....my external is only 35mm

With the integrated bov and internal waste gate, that is two less things that need lines and two less things that can potentially be a nuisance. My waste gate is in the same spot as yours...you know what a pain the dick it is to work with it.


Not at this point in time. I don't see the need. Would I look to? Yes. But the twin scroll turbos are designed to exceed 600 horsepower and that is just way above what I am looking for this year.

The B series frames are good for over 400 and that is plenty for me. I just want to build my car for consistent passes in the 12.5-12.0 range and daily duty. Will it be perfect? Who knows, maybe not. But I still want to find out and see.

I was going to slap on a 2871 and call it a day, but then I started reading about the EFRs. It would cost me over a grand to buy a new 2871. If I sold my bov and waste gate I could have the difference in money for the EFR.

If you know the story of the princess and the pea, that is what our ewg is. I actually have to remove the damn wg pipe to take my turbo out of the car.

Yes the size of the ewg is a big selling point, from a tehorethtical I mean theoretical perspective. The tial 3xmm gate I have now is indeed frikken smaller.

Oh. Only other consideration is the size of the darn thing. The 7670 is 18fucking inches from compressor inlet to turbine outlet flange!!!!!!!!! That plus bov+wg can = BIG ******* BASTARD.

I may have to trim the rear engine bay frame. This time no sawzall tho. I will use a sledgehammer.

Make me want to sell my HTA3582R for one.

I think it would be worth it, I am selling my billet 5857 for one.

Wut? Which model and type are you thinking of?

My S252 gives me many . It is a crazy turbo!!! At 11psi it pulls and between shifts there is 0 lag. Basically the wastegate stays open! I highly recommend BW. My super 60 was way laggier with a 48AR.

Musanovic, any chance we can get a few pictures of your setup with the S252?

How do you like the quality of the turbo? Any issues at all?

That sucks. I undo two v-band clamps and my turbo is out in about 4 minutes - and the rest of the kit stays in the car, including the downpipe and EWG dump tube.

I'm calling bullshit unless you post a photo of a 7670 with a tape measure next to it. The head flange is only 14-15" long.

How about a technicalish drawing from mama borg:

From the PDF:



Look at that ****!!!!

Woops bad math on my part but it is still 14.7 inches!!!!

musanovic

yes turbo does hit hood just a bit. This exhaust housing makes it sit a bit higher.

bad video included that is 10 psi 0 at 4,000 rpm 10 at 4,500.

Umm, from that picture 6.25+4.79=11.04 not 14.7

I think the Absurdflow setups are still in a different category. But as I've learned on this forum, track car =/= street car. If the EFR came with a v-band inlet that would be ****, but completely overkill for most street cars. Especially with the new Inconel studs from TSE Which I will most certainly have.

This is one of the reasons why I want to make a change on the hot side. All the EFR's are 3"(smaller frames) v-band exhaust housings and.................no more bottom mount external waste gate!!!!!! I've got the construction and tear-down process down to a science but I don't want all the extra **** anymore. Especially when my external is smaller than the new internal

Wow, that is nice. If anything, the EFR is supposed to spool faster the the S-series...but that is just awesome.

Thanks for the post. I have a friend who is going for a S256 on hit 1.8t golf, I'll make sure I forward this video to him.

******* damnit **** on my ****. Well that sizing is good news.

IHI

Where can you get these and what type will compare to a gt2554 or gt2560?

Right.. There is no turbo that small.
Also they aren't that cheap: starting at $1400.

Full-Race is the place to get them. The closest thing to a small frame garrett would be the EFR 6258, and that still blows the 2554, 2560, 2860 and 2871 out the water.

6258 is .64a/r t25 flanged. Full-Race says it's good for 200-440hp

* Compressor Type: Forged-Milled Wheel (FMW) Extended Tip
* Compressor Wheel OD (exducer): 62mm
* Compressor Wheel Inducer: 49.6mm
* Max Flow Rate: 44 lb/min
* Built-in BOV: All EFR compressor housings incorporate an integrated BOV.
* Compressor Housing: 2.5" inlet, 2.0" hose coupler outlet.


You're correct, they are not cheap. But not too much more than a ball bearing garrett and better performance all around. Plus you get the integrated features with the EFR series.

I could maybe possibly get the S252 for 900.

No T2 foot print

Hopefully they will have some nice shiz in the 1 series.

EDIT: This would be awesome.

efr bearing vs gt bearing!
