Nice, thanks for clarification Sounds like the 7064 is a neat unit! So compared to a .82 GT30R it sounds like it feels torquier and more responsive and makes a bit more power?

Right now the EFR7670 is back in place. I have been testing the Push/pull WG actuator i made, and also some BOV stuff. New springs, new caps, bigger BOV hole.. Things like that.
Sorry .... what I meant was, is the turbo on a subaru? what's the model, and does it have any resemblance to a stock engine bay fitment wisE?

Please. We mod our cars. That means we are always messing with everything, regardless of whether it is already "perfect" or not. you should know this LOL

It should work as advertised though
I agree with Ron

I wonder if the wastegate actuated issue may also have something to do with the delay also.

Unfortunately this type of thing happens more often than you would think in the specialty equipment segment.

Well I did happen to see this: http://www.treadstoneperformance.com...m.phtml?nik=52

I really do like the idea that the EFRs fit between GT and GTX. That's better for us. I also think that the compressor cover BPV is huge for the aftermarket, especially for those of us still running MAF based. It makes reversed manifold setups a cake, as you don't have to worry about recirculating the BPV on the cold side.

But it only makes sense to release a standard t3 turbine housing. We'll just have to see what the price reduction is from the IWG version.

I completely understand that not everything works as advertised, and that IWG can be made to work. But for me, the advertising was that it works as well as an EWG, and right now that's not true because with an EWG you can use a simple MBC to regulate boost to desired pressure pretty easily. It seems that this is less likely with the current canisters on the EFR, and yes it comes down to price point. It's not that I don't think the design isn't cool. It's really that I'd rather go with what's simpler and more effective right now, and that's with an EFR for the price of GTX to allow me to run a tried and true EWG.
I don't want to be locked into something because the cost was added in, if that makes sense.

But I'm liking the 7064 right now. We'll see

Do you think the actuator you made will fit the TS EFRs? I don't know how different the exhaust housings are between the 2. Will you also be selling the push/pull actuator? Why use 2 EBCS? Did you really see much benefit to this?

Other cars such as the srt4 use more than one, its alot more effective at controlling boost, will also help with per gear so you don't run higher boost in say 5th than 3rd

Maybe I misread, but where did Jeff say that the wastegate does not work as advertised once the proper canister is installed?

Agreed. I'm expecting all of the features to work as intended.

When you are dropping $2k on a turbo because of the feature set, you expect those features to work. Period. I ordered the high boost canister with my 7064. If it doesn't get me to the 25 psi I want to run and stay shut until I tell it to open, I'm not going to be a happy camper...

Best I could tell without going back through every single post, the high boost canister from BW still wasn't providing the results that are expected. I hope BW is listening or planning to make revisions. Or perhaps there are many mislabeled boxes. We'll find out in time...

It was working fine. The canister it came with(mid spring) has the problems holding shut.

First up, this is by far the funnest turbo i have had on my car in a long time!
Back on the dyno today and i was testing the high pressure canister a bit more. Last weekend i was seeing issues with exhaust pressure pushing it open at higher RPM. Before i give up i did some testing making 100% sure the high pressure canister will or wont work. Too bad i am not going to give you the full run down, on that just yet!!

The boost curves below match the dyno graphs below. So This is a bunch of runs shown while i was messing with WGDC and the preload on the WG canister. One was a pretty hot header (done 10-15 seconds after a run) the others were typical cool-ish header runs.

I think what you can see from all this is that this turbo loves a hot header. 20psi by 3350 is amazing feeling on the road. Now 435WHP isn't something new, but what is awesome is that 435WHP was made with only 22.7psi at 6200. Once the boost control is sorted out, i think there is 450WHP on tap and with full boost reachable at 3500-ish, this is very good.

How does this compare to a GT or GTX 30R?? If i give you all the data now, that wouldn't be any fun right??

One of the most significant things is TQ in the area below 3000. There is much more TQ here compared to the GT or GTX stuff, which is what makes these turbos feel so good.

There is for sure more HP on tap, and with a bit more testing on this actuator and then the PERRIN Prototype, i think that worries about the WG mechanism working are going to be gone. Its all a matter of keeping it closed and there are ways to do that!

So take that yellow line, blend it with the red and add 2-3psi from 6000 on up and i think you have a winner!
Is this not the high pressure canister?

I interpreted the move to the push pull was because the high pressure was blowing open

Just for the record, when I say works as advertised, bw made the comparison to an ewg. To me an ewg can control boost without preload adjustments and with a simple mbc without fear of it opening early.

I still like the performance of the turbo, however.

reid install 5 psi spring in your ewg you will have same problem,

Jeff does the high pressure BW WG canister works or not?

Never used the BW part. If setup properly it should work like ours. But in order for it to work to its fullest, you will need to set it up so when it turns on, it blocks boost going to the solenoid and bleeds the pressure from the WG canister.

Any news on your push/pull actuator and if it'll work with TS housing? Also how did you wire up the dual EBCS? Could you possibly extend your great article about WGs to include dual EBCS?

If you have a look at Perrins last post

"Before i give up i did some testing making 100% sure the high pressure canister will or wont work. Too bad i am not going to give you the full run down, on that just yet!!"

It sounds like he never said it didn't or how well it did work. None of the turbos are out yet either by the sounds of it, so maybe if there was an issue, it has been fixed, or BW has asked people to say nothing while they fix the issue.
