hypergear Posted September 1, 2014 Author Share Posted September 1, 2014 I've built a a pair for Chequrered tuning's LS1 V8, that is mainly getting the advantage of running extra timing for the high comp V8. I'm awaiting on the manifold for my GTR, So I don't currently have a result for this particular turbocharger. Are you looking for some thing that suits a Rb20det? How ever I have do have an result using the exact same compressor and turbine, except been in a VNT housing. You can reference to the ATR43SS4-Alpha model. That would give you an approximate peek power and boost to power ratio.

JezR31 Posted September 1, 2014 Share Posted September 1, 2014 Looking for something that suits an RB25, but makes more power than your SLSS2. Was just curious if you had any dyno runs with the SLSS3 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/511/#findComment-7379626 Share on other sites More sharing options...
hypergear Posted September 1, 2014 Author Share Posted September 1, 2014 Power figure would be similar to below: Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/511/#findComment-7379635 Share on other sites More sharing options...
hypergear Posted September 2, 2014 Author Share Posted September 2, 2014 While I'm in here, I have twin GT-RSs on my RB2630 and the rear wheels are choking it up top, is there an option to fit a bigger turbine wheel ? Just a quick update. I'm in the process of making a 55mm exhaust wheel for SR20det motor. That is a mm a side bigger then your GTRs turbine all around. I will doing some evaluations ready, they should be the solution for your current issue on the Rb2630 and pickup more mid / top rang torque also.

XKLABA Posted September 3, 2014 Share Posted September 3, 2014 That sounds interesting, would be good to see some results of back to back against the GTRSs Is there any merit in the 9 blade ex wheels ?

hypergear Posted September 3, 2014 Author Share Posted September 3, 2014 It will still be in the 9 blade design, just over sized.

XKLABA Posted September 3, 2014 Share Posted September 3, 2014 Haha oops, for some reason I thought they where 11 blade, was thinking of something else How long till you start doing these and what would be a guesstimate of cost to rebuild two turbos with these wheels ?

XKLABA Posted September 4, 2014 Share Posted September 4, 2014 Just chatting with Paulie and he has suggested a GTX2867 with the 55mm ex wheel you have mentioned as a twin setup for my car Is that a possibility or what are your thoughts on that ?

hypergear Posted September 4, 2014 Author Share Posted September 4, 2014 Grinding shaft at moment, probably two weeks away. If you wish to send me the compressor wheel I can definitely build them with the new exhaust wheel.

Super Drager Posted September 5, 2014 Share Posted September 5, 2014 Just curious but would you be able to make custom turbine housings aswell?

hypergear Posted September 5, 2014 Author Share Posted September 5, 2014 Should be able to customize turbine housings. Depending on what sort of car it is for. Further development into the ATR28SS Alpha Series based my S14 with a SR20det motor using BC S2 cams. This is a base line for CBB SS2 Alpha version, Vnt is not current engaged. Final result of 302rwkws on 24psi P98 fuel. SS2 Alpha Base line compare to Standard SS2: Makes the same amount of power, but is slightly more responsive. Base line Vs Garrett GT2871R in .64 rear: Its currently making 190rwkws and 21psi @ 4000RPM. It drives pretty good the way it is. The goal would be matching the GT2871 curve without losing any top end.

Lithium Posted September 15, 2014 Share Posted September 15, 2014 So I am helping someone make their RB25 Skyline go a bit quicker, so after much discussion the choice to go with an ATR43-SS2 was made - as soon as we nut out how to best pay across international borders we may have the first Hypergear turbo on NZ soil that I am aware of. Looking forward to checking one of these things out in person after all the discussion, and will be nice to have first hand experience of the SS2 If I'm allowed I'll post results after we are done with it - will be internally gated, stock manifolds all around, BP98 on a stock internal RB25. 1 Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/511/#findComment-7389658 Share on other sites More sharing options...
Badgaz Posted September 15, 2014 Share Posted September 15, 2014 I'll have the atr43ss2 with the external gate for comparison to that lith. Can't wait.

jay-rod Posted September 16, 2014 Share Posted September 16, 2014 Depending on how lenient the dyno is he will be getting about 340-370 hp around there, varies alot with dyno's.Thats at 16-20 psi Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/511/#findComment-7390437 Share on other sites More sharing options...
tricstar Posted September 17, 2014 Share Posted September 17, 2014 Firstly sorry for being lazy. But what is the best direct bolt in turbo for an R33 gts on E85 shooting for around 400rwhp with as much response as poss. Or is it worth going external gate and or big dump?

Dose Pipe Sutututu Posted September 17, 2014 Share Posted September 17, 2014 SS1PU Internal Gate will do it, I personally prefer to run an external gate because you can sneak in more timing Link to comment https://www.sau.com.au/forums/topic/261613-hypergear-turbochargers-and-high-flow-services-development-thread/page/511/#findComment-7391271 Share on other sites More sharing options...
Lithium Posted September 17, 2014 Share Posted September 17, 2014 Depending on how lenient the dyno is he will be getting about 340-370 hp around there, varies alot with dyno's. Thats at 16-20 psi I'll be tuning the internally gated one on BP98 with a Dynapack hub dyno, probably not as tough an audience as you guys are overall used to - though similar to some. Will probably go for around 18psi, but will see how knock limited it is and decide whether to go higher from there.

Don't mind going external gate, prob off exhaust housing. This is for a track car.
