Well you can run say 30 or so on but its not efficient at all.

 

For the WR-2 I would still like to see another tuner get their hands on one for tuning. I mean, I really want to see them do the 450hp rating they mentioned. BB, cool, better billet wheels ok, some porting to the housings, alright. They can only do so much though. I mean in those graphs its showing the power flat line at 5800-6k. That is at only 415whp.

 

There's a supposed 12% "difference" between a MD and a DJ. So at 12% you're looking at 437 WHP / 455WTQ on a DJ, which most people utilize. Seem's pretty good to me? Especially considering it peaks at 6K like you mentioned and doesn't drop under 380 all the way to 6500. Not everyone wants to rev to the moon to be able to effectively utilize the power band shift from a larger turbo.

As you said though, I too would like to see this in the hands of another tuner and on a Cobalt.

 

New WR-2 dyno on Sky Redline

 

oh ****...lol
whats the specs of gas and tune on that car???

 

E100 and the tune is from BSR

 

So Aaron, Goin wit the Hahn 20G huh? I hear good stuff about them but everyone says that it's " old tech" so not sure what exactly that means though?

 

Means the R&D that Mitsubishi did started in late 80's and implemented in Early 90's. Since I'm sure that Turbocharger designs have gotten much better. Especially over the past 6 years.

 

simple is better sometimes...plus after i sell my turbo and chargepipe, my outta pocket will be much less if i go with the hahn...im only wanting to be @ 400whp/400wtq, so it fits my wants/needs

 

Doesn't Hahn spool later too. Like 4k or something?

Also if I go better than k04+ it will need to be direct bolt on. No need to get bov etc. I wanna plug and play. So Hahn, BNR, etc is out WR-2 and ZFR are my only options at this point

 

the hassle of those though with having to turn in your turbo for a core really turned me off with the bnr or pwerks..we will see what happens, but the 20g seems to me the best bang for buck...

 

^ u can pick up a used ko4 pretty cheap now to send to bnr or pwerks

 

My BNR is going up for sale tonight as soon as I finish pulling it off the car. No core needed!

 

Once again, turbo looks pretty good to me

 

you may have said why, but why are you pulling it and selling it???

 

The BNR upgrade on the 2871 is pretty much just an insurance policy kinda thing. In Brian's own words he said that it won't make any more power it's just for a bit more reliability not that the turbo isn't reliable in the first place but there's always room for improvement.

Either getting a new car or buying a gtx3076 setup for next year.

Pm me about what your looking to get out of it

 

i wish i had enough money to do a treadstone kit with the gtx3076

 

No way, I'll have fun with the BNR then later get the EFR

 

Not sure if I want to just wait for the EFR or get something like the WR-2, But Is it really feasable to easily see 400WHP on 93 oct pump gas? Anyone know or think that the WR-2 is worth the money?

 

I think with the right tuner you'll surprise everyone on here with it

 

To people wanting the EFR. If you want more than 400 whp with only pump gas on a non aggressive tune I will probably recommend going bigger than the 6758. I would say 7163 is the better, I would want to swap out maybe in the near future if i'm not too satisfied LOL.

 

Really man? I'm a little surprised to see you saying that. What is it about the turbo that you dislike just out of curiosity? Is it not enough power for what you goals were? If not, what are your power goals and how much boost are you pushing at the moment?

I did finally get around to adjusting ixxgh0stxxi's wastegate, and like I suspected, it had almost no preload on it which is why I was only able to get 25.5psi out of it before even with the wgdc maxed out (mind you this is in my logs, not his rpd). After I adjusted his wastegate we got to have a little fun with a nice 27psi pull and god damn this thing moved out! I can absolutely beyond a reasonable doubt feel confident in saying that i can comfortably squeeze 450whp out of this turbo if he ever wanted to do so. In a long winded sort of way, what I'm trying to say is if you can't get the amount of boost out of it that you expected, you may very well need to adjust the wastegate rod a bit to preload actuator a bit more.

After tuning a 6758 I REALLY want one to be perfectly honest. Great spool, great control, and great top end power all while egt's and IATs are kept surprisingly low. The only issue that I do have with it so far, is the internal bpv does not seem to respond as well as the k04's does. They are apparently both the identical bpv, yet for some reason the efr's isn't nearly as responsive nor does it want to blow off as easily. ixxgh0stxxi says they seemed to have the same spring rate when he pulled them both off to compare, but I'm not 100% convinced of that from what I've seen. I may have to see for myself at some point just to be sure though.

 

I do not dislike anything at all! I just expected to have more room to play with than what I currently am at right now. I believe I'm set for 25 PSI. I wanted to play around with 420-450 whp on a slightly aggressive tune with 91. It looks like that is pretty impossible. I'm probably going to be maxed out at around 420 whp on 91 with an aggressive tune and very high psi, both which I did not really want. I would have to switch over to e47/85 or something to get the goals I'd like at a lower PSI or so. James can clarify more with my tune and what he can get out for me, I'm not sure exactly. We're still not finished yet .

I too will have to get my wastegate checked out ASAP. It's hard for me as I work full time morning shift. My mechanic closes when I get off work haha so I have to set something up with him when we are both available. I think maybe tomorrow I can take some pics and see what's going on in there lol.

AFAIK, I asked Matt@zzp what lbs the spring was and he said it should be very close to stock. So it could be but I'm not too sure, I get what your'e saying though with it having trouble getting all the air through.

 

Yeah I'd love to test this turbo on e47 but there really aren't any local e85 stations around for him to run it as a daily driver. I run e47 with my k04, but I also have a large storage tank and a nice fill-rite fuel pump that I use for fuel storage/pumping, but I also don't use my car as a daily driver so a 40gal tank of fuel lasts me quite a while. Plus he would most likely need to install either the zzp cams or a 5th injector setup to get the propper fueling to support e47 with this turbo.
