Just to clarify:

The SS 7064 has a higher boost threshold then stock. Will it help if it were TS, maybe, not a HUGE difference though.

And boost threshold does not equate to response. It kinda used to when all turbos were constructed the same, but w/ the EFR's lightweight rotating assembly, the SS7064 may in fact be just as responsive as a stock turbo, despite the higher boost threshold.

forgot to post the results of the first dyno session in here:

this is a twin-scroll IWG 7064EFR on an 08 wrx with the full-race kit @ ~17psi peak boost on 93 pump. will be on the dyno again in a couple weeks for a final result @ 26-28psi on 93 pump + meth.

Here's a new Borg-Warner twin scroll setup we've been working on (non-EFR). Straight pump gas, on your typical Mustang heart-breaker dyno:



So far, so good on the s300/s200 hybrid...aka the Cy-Borg™ !!

Updates? Mine put down 365whp @ 25 psi on a 205. Hoping to see better results on a 2.5L....

Okay i know this may not be the best place but my friend ended up with a huge borg warner turbo good for like 800whp turbo and the spool is beyond ****ty for what he wants it for. He has a fullrace twin scroll t4 setup basically. he found a older s200 series turbo with an ar1.22 hotside. the actual compressor size is unknown but its from a johndeere diesel setup i assume. anyone on here have an idea what kinda of spool i will have with this setup? If i need to search elsewhere let me know. i have never looked for a turbo bigger than a dom1.5 so this is all out of my league but he wanted me to check with what you huge turbo guys have in mind.

oh yeah and is there a possibility other hotsides will fit on it from an older s200 BW turbo's? its for his build 2.5L so i am assuming spool will only get better than what this beast is putting down now.

sorry, never got the thread update. hopefully you've already seen the results in my build thread, though. it makes sense to post the final results here as well:

pump @ 20psi peak.
pump + meth @ 29psi peak.

EFR 70/64 IWG, full-race kit on a 08 wrx.

Monki,

How come the meth plot picked up 50tq down low at the beginning of the plot? I'm assuming the meth isnt spraying that early?

i really wish the boost sensor was working on the dyno then i could answer more confidently but meth begins spraying right around 11psi so it's possible with as responsive as this thing has proven.

What I have seen on my car is that even at low rpm, boost builds to 5-10 psi before the natural "spool" rpm. I bet he is spraying meth before the turbo really gets rolling....

If you are talking about the bump up at ~3900rpm, boost builds fast with these wheels, boost has a tendancy to rise quicker than the system can respond to it. With a PID controller, you are normally going to get an overshoot anyway, but even more so with these wheels. I'm assuming that is what happened on this dyno run.

Equilibrium tuning on their Dynocom dyno:

Quote:
This is not from a road dyno. It's from our Dynocom chassis dyno running a .85 correction factor to make it read like my old road dyno software.

Thanks
-- Ed
Their road dyno software ends up about 10-15% higher than GST's heartbreaker Mustang Dyno in terms of HP, and very close to a properly setup airboy plot.

That puts Ed's uncorrected Dynocom right in the ballpark of a typical Dynojet. I don't know how similar the dyno at Maxwell Power is to the Dynocom at Equilibrium, but that gives you some idea anyway.

Just search for threads by mps and u can draw your own conclusions about how it reads. IMO it reads in the Dynojet and dynapack arena.

Ed's reads on the low side.

Well, I received my new turbo today for my full retard project. Just waiting on my engine to be finished then the real project begins... mounting this insane thing. Edit: picture is next to a td04. I need to find a 30R or 35R to compare it to, pictures do not do it justice.





S400SX 67mm FMW 1.25 AR twinscroll. I will probably end up downsizing the hotside but I wanted to see how bad it would really be first. Still undecided if I am going to run it in actual twinscroll configuration or try out a Sound Performance QSV.

Yeah, I knew they were big, but holy cow the size on this thing is ludicrous.

This might be the closest thing I have to a good visual representation of it's size.

Same td04.



I may very well end up stepping down to the 1.1 housing, we will see. I am planning on running a lot of boost, I'm not a lag vagina at all, and it is twinscroll so I will just have to wait and see. Swapping hotsides will be the easiest part of this once everything is together.
