BoostdR

Lol, that's also not true either. I had received the turbo already. You really should stop talking. Your credibility was already down to zero, now your at -10

So you post up the apparently old SS2 boost curve which looks like it actually is a GT3071 on an S14....thanks but the relevance?? And a dyno chart without boost plotted that starts at approx 3200rpm and shows peak torque at around 4700rpm.....thankyou that's looks pretty much spot on. I would have expected peak torque to be at 3700-3900rpm if your words lined up. So we are 1000rpm away from what I was promised, brilliant. The above data was not given to me prior to delivery/installation....and certainly not given prior to you getting my money no that it is relevant at all. If you check our facebook messages I commented about the horrible response early in the peace and advised I would not post up my findings until I had completed all mods. Well mods are done plus some additional to claw back response...how about you actually take some responsibility instead of this pitiful display. It's interesting.. all the messages I'm now getting from others who have had hypergear turbo's not align with your promises. I should have known better, being in the racing industry what doesn't live up to promise shows up on the race track very very quickly. Hard data is impossible to ignore...and a dyno is easy to skew. Hell I could get a EFR 7076 to make 30psi at 2750rpm last week by loading it up for a few seconds on the rollers. On the road it makes 30 psi at 3600rpm in 4th.

https://youtu.be/_i4DIADEABc Full throttle from stand still. Granted boost will be later with less load in first but you get the idea. I'll dig up some emu logs later to show higher gears. PS 7 degrees additional timing below 4000rpm

You offered me another option prior to sending the turbo out and prior to sending the dyno curve. Now it's 15psi by 3700rpm?? Should I post your advertisement stating 20psi by 3700rpm up?? I'm done arguing with you Tao, it's like talking to a child and so unprofessional. If you want to compensate for the wasted labour fitting this turbo up on mislead information maybe we can work something out. I won't hold my breath.

This story just gets more and more embellished. You sent me a dyno sheet wheel after I received the turbo We discussed power and response. You quoted it would make 20psi by 3700rpm knowing what ecu I was running. I'm starting to get angry with you which is not in my personality so I'll stop now. Do yourself a favor and stop bending the truth. I don't want to have to start posting up message screen captures. I upload a video after work so all can judge response for themselves. And I will return your call. Make sure your ready to be honest.

So my turbo was 3 weeks late because I was upgraded to a 200rpm laggier turbo? We had lots of discussion because "I" called you several times to try to get a solid story. You told me I was upgraded for "free" to a billet wastegate causing the delay in delivery. Not that I had a bigger-laggier turbined test dummy turbo. Yes you offered to downgrade me to a smaller highflow after all the delay but negated to give me all the information on what I was getting. I also never said I was going to track the car only that it would be pushed to max flow on the dyno for evaluation purpose. Nice that you made all these decisions for me. Let's get the facts right hey. If I knew what decisions you made on my behalf during all this pseudo consultation I would have chosen the min 18psi smaller turbine. Low rpm boost is so critical to these cars. I can confirm my turbo makes power all the way to 8500rpm. Might be a tad overkill for the low rpm trade off.

I found the last pic interesting. The gas is allowed to pass under the turbine wheel.

Hi Scotty, I think your feedback has been addressed and most likely exactly why my response has been effected to the initial M35 SS2 as I may have the GT35 turbine. My minimum boost level is 14psi with 3 washers under the wastegate. The wastegate flap is also a billet enlarged item. I'll screen shot my response curve and post up a picture of the turbine and flap when I'm out of the office this afternoon so we can ascertain exactly what is going on.

Thanks Tao, I plan on uploading my emanage configuration once I'm done which should help members get to the level of tune required much quicker/cheaper if they end up using the SS2. I'm currently running a MAP sensor and 3" intake which made the biggest difference to down low rpm driveability. I also found the new bosch 95lb injectors to be much more linear over a big name injector and atomise properly(multi orifice over single) which also helped hot start, reduce oil dilution and low rpm driveability noticeably. Matt PS. Intake mod is cheap and easy without the MAF. Seach ebay item number 361310205711 Size is perfect for the SS2. buy some 3" silicone brake scat hose and wrap with some fibreglass header wrap(for the close proximity to the header)

looks like the Holset HX35 has decent Surge resistance I wonder if that is with the anti-surge comp cover which will reduce efficiency up top slightly. There are many factors which will make or break the response. I've seen mixed results. I don't have a solid figure for the SS2 yet. Giving It the best chance to perform I can. I'll post up results once I've exhausted its flow capacity. I expect 270-300kw

The higher stall convertor is a band aid solution. I would rather fix the problem rather than the symptom. I don't even think it would slip enough for this turbo whilst still being streetable(shaft speed differential for lock-up)

Review Hypergear SS2-M35 If you are not willing to run E85, aftermarket ECU, upgraded FMIC, brake wire mod, big exhaust(from dump back), big intake pipe(3"), big injectors, kitted transmission, big fuel pump, no cat convertor, modded BOV: ==>DO NOT RUN THIS TURBO<== Without "all" of the above mods the car is an absolute pig to drive below 4000rpm and part throttle. Even with the above mods this turbo will not make 20psi by 3700 as advertised(that was on an Rb25 with different housings and is misleading advertising)...however it will with all mods start to make "some" boost below 4000rpm which makes it bearable in everyday traffic. Is the trade off worth it for the power output ?...no not at all, the problem is package constraints so we are very limited by choice if we want an easier fitment. The only place this turbo would be faster than the smaller high flow is acceleration from 50km/h or higher. A Garrett 3071 or Borg Warner 6258 or 6758 are much better options for average power "if" you are willing to make them fit. I was told on purchase that the SS2-M35 would be reasonably responsive then to be told on delivery it's response would equal a 3076 .82 with the power of close to a 3071 .6 which I would agree with. Matt

Interestingly I found boost cut to be right on max injector duty cycle so if your ever hitting boost cut your running the chance of running lean and knocking. The factory know what they are doing we are all just playing catch up [emoji4]

20x10 all round +35 3mm spacers up front 255/30/20 Not rubbing at all. Needs to be this height for the camber to pull them underish the guards.

The boost valve controls this. Opens up and lets vacuum bleed off some pressure to the wastegate for it to open up later for high boost. If you re-route the line from the intake pipe around the solenoid to the tee piece it will stay high all the time. ie: join the two vac lines going into the solenoid together.

The stock BOV plastic disc is floating on the shaft and starts to leak with age. I replaced mine with a GTR item from my old 33R which doesn't use the bleed hole and has a larger discharge area and metal disc over plastic. Spool up improved. No shudder.

Now that I'm running a MAP sensor I can do cool stuff like video what this brake mod actually does. Enjoy. Matt http://youtu.be/P5ZTIWufwF8 http://youtu.be/dDkkwpAc9pc

That's correct. Check O2 sensor and pipes for leaks

Get a cat back with an oval center and oval rear muffler to be quiet. I run 3 large oval mufflers and it's very quiet. Taking the cats out will make it louder Matt

Sounds like the fueling is off. What part number MAF went in?

Bypass was via the EMU. Speed limit can't be adjusted by the EMU Working on an EMU speed input so I can program launch control with ignition retard. I haven't setup the parameters for fuel consumption. But I imagine the data would be accurate if the input settings are accurate.
