I was always under the impression hypergear did turbos for other cars, but as this is a skyline forum, we only hear about skyline related turbos?

I guess I was wrong.

You are absolutely correct. Stao even mentioned he was working on a turbo for a VW Golf, so I take this as interest in moving towards other markets and keeping with the times. Regardless, Skylines are not over and done with for aftermarket parts...far from it in my opinion. In fact, the market segment for companies like HG is larger than ever, simply because these cars are becoming more and more accessible and they aren't worth spending big money on big brand stuff anymore. I know you guys are just trying to help with your feedback, but don't you think Stao would be doing what you're saying if his current system wasn't working for him? Also, FWIW I didn't buy an HG because I can't afford an HKS, I bought it because I wanted to have some fun with an experimental underdog, not use a turbo that has been tried and proven...I wanted to do the trying and proving.

I'm pretty sure he will still build you a cheap high flow for ~$1000 if that's all you want, but it's not what people want anymore...this thread has had nothing but talk of SS1PU and the G3 over the last couple months, they are what people want. So you got your wish for two models that Stao can focus on improving and I'm pretty sure that's what he's been working on lately. As far as previous customers buying turbos and having them superseded...er...Stao is always offering to upgrade people's old turbos for them with the latest modification at little or no charge. He does NOT owe them this, no other company I know of in this industry will offer to do that for customers and it's a moot point to claim the R&D isn't worth continuing on an RB25 turbo yet claim that previous customers will experience dissonance over their model being superseded significantly by the latest improvements - which one is it guys?

As for beta testing, who cares as long as people are happy with the product. People know what they are getting when they buy a turbo. Yes Stao creates a turbo and puts up a few dyno charts...but he doesn't say "this is the new turbo you should buy" - people practically say "give me that one!" and demand he makes them the same turbo. So what should he do, "sorry can't sell you one, I haven't spent hundreds of thousands on testing it yet..."

/rant

tl;dr don't like it, don't buy it, there's no pleasing some people

lol sorry guys, I don't mean that to sound harsh either, just feel like there's a bit of misinfo being chucked around for no particular reason and I'm somewhat tired/moody (male PMS).

*changes tampon*

lol, i knew you would have a rant...

*Artz goes to look up meaning of dissonance :ermm: *

Haha once you know it you'll use the word all the time.

The RB25det is a good engine for a research ground, results from it can be used to estimate power range from a specific turbo combination on similar sized engines.

Looking back to results generated with the old TRxx series, new series take a giant step forward in performance. Take the ATR43G3 for instance, it had same response as the TR43i but makes 70kws more top end, while the ATR43SS1 makes similar power as the TR43 with twice more mid range, they are not comparable.

The same car's been used for testing and evaluation through all those years, Even running stock engine it was producing similar power as what it is today based on same boost, running hub or roller dynos with 3 different tuners.

The final evaluation figure pre-release means the turbo is capable of making what it made, So the differences could only be in supporting mods and tune. And there are people getting evaluation results per boost level.

A large section of this thread is problem solving and support, it is a good write up in many cases of how people find the problem, sorting it out and ends up with the desired performance.

Turbocharger development will kept on going, we can only come up what I believe is the best during the time been, and improve out comes as project progresses.

I love the turbo btw.

Wouldn't mind the boost issue to be fixed but I will speak to Stao about controlling this.

Everything else is perfectly fine

Most aftermarket turbos with internal wastegates have boost control problems, EBC is a requirement IMO.

Trying to control flat high boost with big back pressure with a simple linear spring is borderline impossible imo because as the rpm increases it chokes more and more so you need a changing gain factor (the spring) which is only really easily achieved with an electronic controller.

The reason a lot of people manage flat boost on garrets is because they are running much bigger exhaust housings where the turbo doesn't choke up as much. it isn't because it is a "better" designed turbo imo.

Edited by Rolls

Kasko please check my youtube video under: taosg2001 for preloading instructions and just check to make sure the gate is tightly shut by the actuator with about 3mms of preload. That will get even better response as the gate don't open as early. This should be the correct boost curve that matched mine

Preloading the spring won't cause the boost to go higher then the preset 20psi will it?

Also will it put at DVS's tune?

If its currently lose then making it tight with about 2~3mms preload won't affect much. But check boost controller once you've done it.

It never seemed loose from what I remember when installing the turbo.

I didn't play around with any of it I just got the turbo in the mail and bolted it straight on.

I'll check this afternoon after work but

Stao, have you thought about fudging your results to show LESS power, that way when people actually make more power than what they were expecting, HG turbos will be all the rage? ;)

LOL thats actually a really good idea.

Under rate the turbo, keeping expectations in line with response and let end users be happily surprised in the end.

Well Kando did have the advantage of being initially perceived as cheap chinese eBay shit lol. SURPRISE!

Talk about a mad troll right? lol

Anything repro' MHI is awesome. Just look at Hyundai!

LoL have a look at the dyno footage, you will note all the runs are pretty much within 10kws or less. That 330rwkw G3 had variance of 5kws pulling runs all afternoon. :blink:

exactly, and if people don't trust status to give an accurate result then we are all f**ked.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
