  1. Thats my tire pressure. We were in Heathcote again today. The car's having some issues, I might have installed the new fuel pump too high as it had fuel surging issues, gear stick snapped out, and since the new tyres gripped lot hard the diff seems to let loose. Its occasionally doing one wheel launch. Not sure which diff to get yet. Over all we did end up with 4 good runs and the best one was 12.26 with 124.76 M/H The tire shop pumped my tires to 40psi. We first dropped it to 26psi, then further down to 16psi which it grip the most. It started to rain in the afternoon, so the day ended early. will post some videos later on.
  2. I don't think any part of this package would survive on 40psi, been told its running 20psi.
  3. This is a dyno reading sent from a customer in Sweden using a older model ATR43G3 in .82 type A rear. made 477rwhp on pump 98 fuel. Its got ebay manifold that holds the turbocharger in stock position, internally gated with all the bolton bits. Can't understand their language, details are at: http://www.garaget.org/?car=257470
  4. I bought a wheel and tire package 3 years ago and I have no idea what those rims are apart from they fits. lol Any way. quick update. This is our latest VNT turbine system using a ball bearing SS2 core. I don't have a high speed camera so this footage was taken with a air blower meter away from the turbine housing with VNT nozzles engaged and disengaged at low shaft speed. Notice the change in shaft speed with VNT nozzles engaged. Will be testing it next week when Trent has time, and hopefully I will get stock response with 370rwkws.
  5. Don't know what they are. It says M/T special compound. lol probably semi slicks The car is all stock apart from engine bay mods.
  6. The original plan was running small 16inch rims. and it turned out the majority of popular tires sizes is out of stock. My only options was the 235 or 275 in 17inches. Taking the 275 is bit of gamble and lucky enough I had a set of spacers. I will be switch to cross plys if this is not good enough. By the way any one wish to swap mine with a Stock R33 GTR? I would like to do some thing with Rb26dett engines for a change. Haven't tried SS2 wheel with Mitsubishi housings yet, but I don't see that been any problems. Might do up Trent's V8 turbos if he's not getting enough power.
  7. It says it is street legal been radial tires. I think they are alright.
  8. Got the 275 Micky thomasons on, they just cleared the guards and required 5mm spacers to miss the strut tower. Really good tries. With the SLSS2 doing 22psi full throttle lunch in 1st and 2nd it didn't slip a bit. Price wise it only cost me $285 each just $10 dear then the Federal RSRs. Highly recommended.
  9. The new SS2 is still WIP, almost complete. Will post results if the ideology works. Car's having issues transferring power onto ground been a rear wheel drive. Getting slower times with more power. If this don't work then I will be going for a full set of cross ply wheels and tires. That short shifter Trent complaint about has also been replaced with one came out of a OEM GTR. If every thing goes as planed we should be sitting at the 11s mark with 125m/h.
  10. Yes I will add some information into my site. Also as some of you already noticed the new domain is at: www.hypergearturbos.com The old domain still works as a back up and file storage. As things getting a little more serious, I've got my self a set of of MickyThomasons ETs for Sunday's drag strip. I was hopping 265 x 16s which VPW run out, that I already bought a set of rims for. Those are 275 x 17s hopefully fits my current rim with much better grip . RSRs (255 x 17) are for sale at $300 a pair if any one is interested. they are under 500Kms old, pretty much new with 95%+ threads. Good for 300rwkws class. Compare to the very fist SS2 the comp wheels has been altered 5 times with 2x different types of compressor housing and 4 different types of housing profiles. They are obviously a much better performer externally gated on proper manifold as any other turbochargers. The very first one are still capable of making over 350rwkws on E85. The current once can pump out 376rwkws with better response and much lower boost controller duty. I've got another reading to upload comparing the current SLSS2 V SS2 that is pretty interesting to be looked at in terms of difference in boost, power and torque delivery. I'm also working on another SS2 prototype that is made to be externally gated only and more responsive then the current model.

Big thanks to Status tuning as usual. Just out of curiosity of what the 10cm L2 turbine can pump, We tried every thing to squeeze power out of and The maximum we've got it to was 385rwkws on 24psi. The car refused to make any more power after this. At 22 psi it made 374rwkws so basically identical to SS2 at same boost level. This goal of this turbocharger is to make better power then a T67 while having the same response to a 20G. I've overlaid three readings from: Our brand new SLSS2 turbocharger V Latest SS2 turbocharger that has the identical compressor setup on lower boost level. V The highest reading of a T67, Greddy manifold, externally gated. All on Rb25det with stock cams.

  13. That was a ATR28G4 turbo, That specific one is an older older model made around 2008. The current one is quite different, makes better power and response.
  14. from my testings, running the same turbo externally gated on turbine housing with stock manifold made less power then the same turbo on aftermarket manifold internally gated, and even lesser against aftermarket manifold externally gated. Turbine housing has been untouched all times, the manifold is restrictive. So scientific solution would be attaching the external gate to the manifold. But factory manifold is twin log, do them properly requires extra work and skills, (I'm in process of building one at moment) while external gate from turbine housing makes the job easier.
  15. You do it on the manifold. because it is the most restrictive point.
  16. I think it should do 375 rwkws on 22psi with stock cams on E85 with plenty of mid range power band and torque.
  17. ^^^^ Those is definitely educational materials. would be great if you can post a write up on those cams. Below is the latest SL21G, or you can call it the SLSS2 or S(L+S2). Basically the Current SS2 with SL2 turbine in 10cm housing. Its suppose to be on the dyno today, Unfortunately my Walbro 20000262 fuel pump burnt out last night and my car was tolled back by RACV lol. Its getting a 20000267 pump installed very soon and getting tuned in a week time. Below is photo of the new prototype (and the dead fuel pump):
  18. Customer had one and it also cause the turbocharger to boost creep from a tight divider in the center. Which's apart of the reasons that his turbocharger came in for high flowing with no turbine wheel. I need to get one of those for mine to run 30psi on.
  19. Further up dates. Most of our work up to date are around the 500HP range. We've improved power, response as well as boost control ability featured in the latest SS2. up coming for trail: TD06SL21G featuring current 74mm SS2 compressor assembly. Take effects of this compressor behavior from the SS2 it should be able to pump through greater volume of air through out of the external gate in combination with the SL2 turbine. If the end result comes out same as the SS2 then we should have a L2 based turbocharger that has the identical response to a 20G while making more power then a 25G with fatter mid range torque. I've handed over two drawings of additional billet compressor wheels to be cut, this is relating to the SS-4 development. Those wheels are engineered to produce the 450~500rwkws range, My injectors are maxing out and needs cams. but do let me know if any one is interested for the trail and I can work out a special price.
  20. I see this before. The result should be no differ to other turbochargers in similar sizes. There used to be another company making a oil and water free turbocharger. By hanging the bearing cartridge on front of the compressor inlet while having the turbine and comp wheel packed onto the other end of the shaft. Grease up the cartridge before use and it becomes water / oil free air cooled.
  21. That is true, I've mentioned it before, some the housing castings Came in from overseas. they are quality castings, been through time and well tested. Join in part of globalization running through any other firms. Other wise it is not possible to produce at a cost that the majority can afford to pay today. All machinery work turn casting into some thing useful as well as CHRA work are precisely done in Australia. That takes the majority of the cost in building the actual turbocharger. I've been pushing up in volume to drop costs so our products are more affordable, how ever I can not get rid of the cost of factory on goings as well as keeping good engineers. About Chinese workmanship, we are seeing poor quality / low performance turbochargers because the people whom manufacturing them does not know the actual purpose of their products, instead paying more attention into what makes them $2 by such time it sales. They are businessman, not engineers, certainly not a automotive enthusiastic or have any knowledge in modifying a Skyline. If I do fully establish in China, I can hire quality engineers at $5/H and train them to precisely build what I wanted, with much less running costs. Pass on all of that into consumers that takes away close to half of the retail costs. But its only worth considering if I have a permanent place in Chinese domestic market.
  22. That one was $1100. I have a side mount manifold that you can have at same cost which holds the turbocharger on stock position. That has external gate port with plug made in case of running internal. Hopefully so. they are still setting up a Testing rig there. If quantity is big I will move over there and build turbos for your guys at half price.
  23. After I give it a full cat back exhaust the boost level jumped 1.5psi. Did many launches measuring 0~100KM/H time. Its now sitting on about 7.5 secs from 14.5 factory (<= can you imagine what 0~100KM/H in 14.5 sec is like?).
