There is nothing wrong with DIN or SAE configuration, I'm building VW turbos for few Chinese and European work shops, and their standard dyno meter configuration is in DIN, Many Jap dyno meters uses DIN configurations as well. Americans uses SAE. It is up to how people interpret what a horse power is. Just like the French might have an different opinion on what a Kilo-gram is. Trent at Chequrered Tuning said the difference between the two is 15%. I can't yet judge that. I will ask Trent to do a run on both configuration on my next tune.

First of all it appears the Standard Dyno meter interpretation used in NZ is DIN. Using that interpretation, the reading is higher then what it usually would be is in OZ. The bush bearing turbo does not have an affects in terms of strangeness in the curve, how ever the response is slightly affected by oil temperature. The Blue run of 285rwkws had a different name on it, That is not from your car is it? The power level seems to be ok for the amount of boost given and auto transmission.

Its 12 volt and draws a maximum of 100Amps, so it would be similar to a Starter motor. It only comes in for about 2~3 secs a time. It will be a long time before I can come up with some thing working properly. But VNT stuff do work. and do make a lot of differences. eg: Standard ATR45 (GT3582 equivalent) result based on: R33 GTST, Factory spec engine, with high mount and external gate. 431rwkws @ 25psi E85 fuel, full boost reached at 4650RPMs ATR43SS-4 Alpha. makes 435rwkws @ 25psi also, while making full boost by 4150RPMs, Nothing's changed except turbocharger:

Fist of all, Don't get too excited, this has a long way to go, and I'm just working on it with spare time as a Hobby. The electric version generated 3.2psi of boost once engaged. How ever engine consumes more air as it revs. So boost level declines as engine RPM increases. Still a very noticeable amount of gain compare to NA: Reds are with Electric assisted only. Green is NA. The electric motor can not be strapped onto the turbine shaft, it must be isolated when turbine shaft speed is greater. Per Boost curve above, Ideally would be having electric motor to detached at 70.000 turbine shaft speed, and that is 3.2psi on this specific compressor. This turbocharger the way it is, currently building 3.2psi at 2500RPMs. The Electric motor should add momentum to the turbine shaft, Once electrically assisted, we would have 3.3psi at 1000RPMs. So I'm expecting an difference of 1000~1500RPMs. in which we might see 490rwkws with 29psi reached by 3800RPMs.

Currently working on Electric assisted turbocharger prototype. It is currently getting the 490rwkws SS-5 turbocharger sitting on 3.2psi with car powered off. That is totally lag free.

I think thats why Brazil only kicked three goal against China in 2002. lol

I noticed the factory diff always spin one wheel much harder then the other on take off just like in the clip. Happens to mine as well, Its alright once in third. Rolling start might give the skyline a better chance of winning.

LoL. World Cup is suppose to re-enforce the friendship bound.

Looks similar, yet two very different turbochargers. SS3 is no longer using L2 turbine, it is larger on both compressor and turbine end. Obviously in usual situations more HP is based on trade for response. From experience, 20psi will be at 4100RPMs, will post up result once dyno reading available.

I'm usually around during business hours, Please call 0413457185 before dropping by.

Thanks for the feed back and looking forward to some drag video footages. This is an update based on our SLSS2 Turbocharger, Is the SLSS3. This particular one is aimed to produce 400rwkws on E85 with optimum response. And of course I have made a ball bearing version of it as well as bush. It is running off an TD06 based, 10cm T3x turbine housing.

Some updates. This is the ATR28G2 on my SR20det S14, VCT enabled on pump 98 fuel. Final result of 267rwkws peek 24psi. Since some readings might be depending on dyno. I will run them against a close match of more popular models for end user's power prediction. Running against a GT2871 in .64 turbine on Greedy easy cams. Since my cam shafts are much bigger. Hines the extra top end. This particular turbocharger has very similar behavior to a GT2871R.

Great result. more responsive then mine, even thou I had VCT enabled. Its do 190rwkws @4000 RPMS. That would be a great to drive. Have him compared it with other turbos on his particular dyno? if so whats would that be close to on a similar setup?

Well he's a truck driver whom wanted a fast daily, doesn't know much about cars or knew my car has 380rwkws. He believes its just a stock "GTR" R33 with a pod, exhaust and fat tyres. He said "nothing beats the Godzilla" LoL. And yes more "leg" room would be nice.

Some updates. This is in reference to our CT15B 1JZ VVti high flow.

I pulled away. on the same time it was with a special turbo that built 23psi at 3500rpm.

I run my neighbors' EVO9 that has 240awkws in a straight line. My R33 had 380rwkws on vnt system, it pulled away in third gear after 140KM/H, that was with Mickey Thompson 275 ET tyres also.

Far as I know it was old turbo off, new turbo on. And every thing bolted back in place. The 20G started to run out of puff around 5000RPMs as the boost curve started to decline. This is the latest version of of the SL20.5 also, with SS2 compressor wheel, It should crack 380rwkws towards 24psi.

New Result sent in. This is from our TD06 SL20.5. Final result of 358rwkws @ 19psi. On an R33 Skyline unopened engine, 40mm external gate, fuel and ecu mods, E85 Fuel. The same car had an Kando's TD06 SL2 20G before turbo change. This is an direct comparison between the two.

Got a reply. The R33 plug in ecu only works with Manual. You will need to run a piggy pack and keep factory ecu for Auto commands. I can supply the E420d at a reasonably good price for existing customers. Please do drop in an pm if you would like to run that Piggy pack ecu.

The Just jap will will do ok, Just need to die-grind the flange area to suit the factory dump gasket. I will make an inquiry for you about the plug in ecu with factory auto.

Our "Journal bearing one", is more responsive then your ball bearing one, and last 10x longer.

Well mentioning one seizing up after 3 dyno days plus paying additional USD for warranty aren't words of encouragement. I was the first few people on this form whom trailed those back in the days. There wasn't much alternatives for direct drop in injectors at this capacity then. I will just stick with P98 fuel for the time been. People can use the correction figure to predict E85 results.
