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.

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.

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.

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.

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?).

http://www.skylinesaustralia.com/forums/topic/261613-hypergear-hiflow-service-continued/page-355 New G3 has: +11 Kws power, +150RPMs better response

and more power

some turbo updates: This is the newer version of the SS2 high flow. I've turned the compressor wheel into the 11 blade design. Probably because the tight packed blades is more effective in trapping air in, it required a lot less wastegate duty cycle (some thing like half) to hold 22psi of boost. So on a internally gated setup it should make a difference in terms of holding steady boost at upper rev range.

I'm running RSRs. They are pretty good on road, probably because I rarely drive it on full throttle. They are not good drags.

Congratulations on the time Jay-rod. Good tyres and more practice made a difference. Great work. Artz: haha yes, having Trent sitting behind steering wheel is like me driving with light weight Porsche wheels with carbon fibra bonnet and boot, plus no interior. He's used to drag VLs with Nos also lot more experienced.

the gate size is determined by the diameter of the actual wastegate port that sets against the manifold. The 50mm gate is $350. fully machined from stainless steel casting.

Rizz89: Well if we did that high flow on the VL then it will be bit laggy for the Rb25det how ever it should produce more power due to larger wheel profile. Get Plazamaman's cooler kit, proper injectors and a tune. R33's pretty heavy, is the Skyline in the video been fully stripped for drag? I will ask Trent to lose few pounds or askt Cat to drive for the next drag.

I'm using power enterprise 850 injectors. They cost abit more but they are very good and direct drop in. They started to go lean at 430rwkws, but that is above the maximum efficiency of the SS2 turbocharger. Those injectors where bought from CJmotors I'm running a 50mm gate made by my self, So I can make you one if you are not in a hurry or use a turbosmart 50mm gate.

^^ That is very responsive for a SR20det. Not your car? Also latest video from SSRicho. 1.31 lap time run at winton raceway. R33 skyline. running our 21U high flow on 263rwkws.

The 3540 in 1.06 turbine is a huge turbo for a Rb25det, and he's only 3m/h faster, I think I can get that mileage on 23psi with G3 on MT tyres. And yes I'm making an 11 blade wheel profile for the SL2 at moment. Aiming at T67's power with 20G's response.

Thanks for the info. I will look into those. It seems most of the cars that managed to run good times had stupidly large turbochargers on. From the turbo to engine size ratio on those things appeared to be very laggy. That's probably when launch control comes handy. Turbo building option for fast on quarters and feel good on road can be very different. Be interested to see result from the laggier 431rwkws G4 profile as well as the new Sl20.5 and Sl25.5. With proper tyres and gear shifter.

I got a used ATR43SS1 came out of a test car. It made 230rwkws on Rb20det and has same response as a stock R34 turbocharger. This turbo also boltup to factory manifold, dump, and water lines. Price is $800 including oil feeding line and a high pressure actuator. PM if interested.

Also last footage of Winton track day from SSRicho. Running 263rwkws, using our 21U high flowed turbo. Fastest lap of the day. 1.32

Here are the video of the last two runs: 121m/h run (18psi) 125m/h run (20psi)

I'm thinking what happens if run a 1.06 turbine end on the G3. it should take away all the zappiness down low causing wheel spin while kicking in mid top range while the car's rolling at much higher speed.

GtScott: Would great if you can pass on a link to those pineapples. I will have a look into them. Been recommended to Mickey Thomson 16inchs drag tyres. Will need to source that and a set of factory rear rims. I took few video footages in bystander area. Will upload shortly.

^^^ haha we submitted the post on the same time. Just came back from Drags today. I can still taste rubber in my mouth. This is the very first time my car's on the drag strip. It was some how of a test run. Trent was my driver for the day as he would know whats going on incase if any issues. It was a factory weighted R33, We did not do any weight deduction work to the car. We've got 6 runs though out the day. Because observation of the car's performance is mostly on dyno, so we did run in to couple of issues. And the Federal RSR tyres are horribly bad for drag strips, no grip WOT in first, 2nd and 3rd. The problem runs: First run was 17.9sec with cooler piping popped. I guess thats a NA R33's drag time. @ 75m/h 2nd run was 14.94 Hitting boost cuts. 78.1 m/H . I install and trail 2~5 different combinations of turbos every week, but did not record the EBC settings for individual turbos. 3rd run was 13.92 @ 116.7 m/H. This car came with a quick shifter, how ever it doesn't go into gears in high RPMs, this problem carried on to all runs done today. 4th Run was 13.66 @ 122.28 m/H. Car had fuel surging issue 5th Run was 13.55 @ 118.17 m/H. Car continuing to have fuel surging issues. It wants to stalling or bogs down after gear shift. After more fuel added (3/4 of tank full) this problem was finally solved. The last two runs were mechanically trouble free apart from unable getting into gear and no tyre grip till 4th gear. 6th Run was 13.26 @ 125.63 m/H , 60ft 2.3 sec, @ 23psi of boost. (Add: After check data log it was 20psi instead of 23) Because of the car had no traction, we finished the day with a lower boost setting and surprisingly it run faster with less m/h. 7th Run was 13.06 @ 121.42 m/H, 60ft 2.5 sec, @ 20psi of boost. (edit: After check data log it was 18psi instead of 20) The turbocharger run today was a externally gated ATR43G3 in .82 turbine. We should be hitting the strip again on 12th May. I will replace the gear shifter and Will be getting some proper MT tyres. Hopefully be hitting into the Mid 12sec with around 130m/h speed.

As explained before the savings comes from the turbine housing (cost by KGs), that requires less parts or machinery work. Compare to the ATR43xx series, because they were built in matched housings, they do picks up more mid range, and better response. So they are still the better bolton / Ext gate turbos. But like I said it is a cheaper alternative, and will perform better then standard high flows. And I guess the biggest advantage is that a donor turbocharger is not required, which saves lot of time and shipping fees. I will see if there are room to dropping pricing on our current standard high flowing service. and will pass that to our customers.

Releasing a cheap bolton turbo that is capable of doing 280rwkws internally gated. The ATR43 3.5. I've done a fair bit of sculpturing in to the imported china turbine housing. This turbo is capable of making 350rwkws on E85, external gate. I will mark this price on $1100 including the oil line and high pressure actuator. Result of this turbocharger is page 366 Note since the turbine end is largely over sized. Make sure the factory dump pipe gasket and dump pipe flange is all touched up as its not in the way of flow. I will sculpt another turbine housing for it that supports both external or internal waste gating like the SS2 .82.

Thing in China is. If one business makes money by copying some thing (doesn't mean it works), then every one else follows. They will also try to produce and sell them at a cheaper price. Externally they appears identical, internally they could be very different.
