    The wastegate has been bored out to suit the disc. I have slotted where the bracket is bolted onto the compressor housing, so if you lose up that two bolts you will find it can move up and down. It looks like its been preloaded already so no need to touch that. In this case you might just need to get the car tuned with timing and fuel adjusted. I can supply an adaptronic ecu at a cheap price since you've purchased the high flow service from us. Please PM for additional information.

    In theory low ramp rate should give higher out put as things are colder. My R33's pulled higher numbers with better response on paper at higher ramp rate, that applies to pretty much all turbochargers that I've trailed, specially to turbos with larger turbines such as the G3 and SS2. I guess you can do few runs with different ramp sittings and find out wither if its only applying to Dynapack dynos. Trent usually uses 12 secs ramp for tuning, all results posted are based on 12 sec runs. Hy_rpm, please keep us updated. Cheers. Also for the 20 customers whom bought the promotional SS2s. Please post up some updates and results when ready. Thank you.

    My car made more power and better response on paper with higher ramp load. Green is 9sec ramp, Blue is 16sec ramp. All the current runs are based on 12sec ramp.

    I have slotted the actuator bracket, preload the actuator and see if that helps. Factory 21U turbine ended high flow has similar response to stock turbo with a manual, but I'm not sure what its like on Autos. If it is an OP6 then it can make a lot of power, but will be down on response.

    I run E85 with those only. Probably is the reason they worked. The older injectors I used was Deatchwerks 550ccs which worked fine on P98, Next size up was the 800cc Power enterpise injectors. Very good, worked fine on P98 and E85. How ever maxed out at 430rwkws on E85 Then was the 1200cc 5xOs, that I got it up to 490rwkws. Didn't last too long how ever, and I had to pay for warranty. So lol.

    The 1200cc on E85 worked fine on my car, apart from one seized up. Alternatively check out Deschwerks 1000ccs. I've used three sets of their injectors and sold many with the KIA kits to China, no issues so far.

    No worries. Personal opinion that is one of the best turbochargers I've trailed so far on the S14. Had another customer with a 180sx reported 280rwkws on P98 fuel with full boost by 4300RPMs. Will post result once its emailed through. Some footages from John Reco. That is the World time attach, fastest lap of 1.05 sec. Running 700cc injectors, PFC, Our high flowed 21U R33 turbo internally gated, E85 fuel, Tuned by Chequrered tuning, Making 310rwkws @ 20psi.

    Did that have a OP6 mark on the rear housing?

    VNT systems are not yet the main stream performance turbochargers because the years in practice of the ideology by OEM manufactures is not in high performance field. So it comes down to who made it for what purposes. The most important engineering element of ours is reliability, In which you find all sorts of reported turbo failures except ours. The development of VNT turbine system has been welly documented, Starting from: http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-390 Check thread index for final outputs. This covered three types with peek power rating from 380rwkws to 490rwkws. Most of evaluations was carried out based on a Rb25det motor, I'll be more then happy to offer free trails if you are in Melbourne.

    Just run a SS Alpha Variable geometry turbo. That will gives you both down low and up top. Use it on stock engine, factory cams and factory cam gears. Saves heaps of marking around also.
  11. hypergear
    I can swap your current dump assembly with a Blanking plate for external gating. Just unbolt it and send it in when ready. The oil line if its for a high mount you will need it to be in a meter long, the length will be a dash 4, no restrictors.

    Been quite busy lately, posting up some dates. This is an other result from an ATR28SS2, Customer reported initial run of 279rwkws @ 22psi, out of a factory SR20det motor with Tomei step 1 drop in cams. Final result is 261rwkws @ 21psi and 273rwkws @ 23psi retarded 3 degrees for the longevity of the motor. Dynoed on pump 98 fuel, 20psi was reached @ 3900RPMs.

    The wastegate flapper has a smaller tolerance of play that is to compensate for any changes might be during heat expansion and contraction of the turbine housing. beside Jay, your rear housing was cut and welded to suit an external gate. This particular car has an external screamer. For 1000RPMs difference, The take would be half of the 38mm gate. It will be making a very noticeable sound. OP have replied on an earlier post as the screamer does not make any noises till the gate opens. Plus this behavior was not present after the new engine was assembled. In my opinion The waste gate assembly on this turbocharger is unrelated. I'm not sure how bad the older engine was damaged. If bit of failed engine ended up in the turbine housing, then it might be accounted for a damaged turbine wheel. It could rise the lag issue also, how ever on the same time it is not capable of making any power. I have experienced similar issues in the past when my VCT was dis-engaged, since it has been previously burnt, functionality of the part might be questionable. Simply unplug the solenoid and feel for the changes in drive ability. No differences usually means malfunction in the VCT assembly. The adjustable exhaust gear makes pretty much no differences working with stock cams, It was the first thing I've tried improving boost response and that was a waste of dyno time.
  14. hypergear
    As mentioned above. Check VCT, and Actuator preload.

    To high flow it will cost you $850 including braided oil line. I do have a couple of different combinations, smaller profiles is more relatively more responsive then bigger combinations. Power wise smallest profile can support 210rwkws with full boost around 3800RPMs, while the larger profiles can handle 240rwkws with full boost around 4500RPMs. The adjustable cam gears helps a tinny bit of mid range. But not a very tangible amount using stock cam shafts.

    VCT enabled SR20dets are surprisingly good, the ATR28SS2's managed to pull 275rwkws with 20psi by 4000RPMs on a customer's car yesterday. The SS1x series are made for Rb20dets, the power delivery on those are more linear down low. and has the capacity to pull some good top end internally gated, as a factory bolton turbocharger. We build SS1.5 billet fronted TD05 turbos also, those will out perform traditional 18G, at similar pricing levels. Those are best externally gated.
  17. hypergear
    Cool, Working on an ball bearing version of TD06x based turbochargers at moment. Pretty challenging so far as the bearing housing is very short and cast without much materials in it. lol. I will up load photos once completed.

    Email adaptronic for the gauge, there is one that can be wired into the ecu and give you real life reading on both the gauge and loges with the ECU. I've got that on my Kia, works very well and very handy when comes to road touch ups.
  19. hypergear
    Yes can be done. Its not an issue.
  20. hypergear
    It does looks stuffed. and the comp wheel does not match to the compressor housing profile. It needs to be re-high flowed.

    Couple of drifting videos. this from our rebuilt GT3582R turbocharger working on Simon's S14 Rb30det motor: Suspension footage:

    Results sent in from another customer. This is an ATR28G2 on an S15 with tomei drop in cams making 227rwkws @ 18psi on pump 98 fuel. I think it is an fair number considering the car has been mildly modded to be street legal. Customer is mentioning stronger actuator with more free flow induction, cooler kit and exhaust in near future so hopefully seeing an higher numbers from it soon. Also noticed the dyno run was using 5th gear?
  23. hypergear
    Usually it is the opposite as the engine has more ramp load with wheels locked up on the rollers. You can by pass the boost controller and run vacuum source directly into the actuator and see if that helps in any way.
  24. hypergear
    get rid of the cat first? Its good power for a RB20det, I'm sure you get more power without the cat. Check to boost controller and the hoses that goes from it to the actuator and vacuum source. Usually it won't boost creep if its not doing that on the dyno.
  25. hypergear
    For 10psi or under, it works pretty fine with stock ECU. The profile above would be as close to stock configuration as possible. But at moment I don't have a drop in core to replace the factory chra. Pipster11: Please check your email. I've forward you with a special offer on an high flow service. Cheers.
