I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

Would it possible to plot the hypergear turbos all on the one graph?

I.e. standard v highflow v ss-1 v ss-2 v the one his working on atm?

Would give us potential customers an easier time to compare them :D

Would be great, even better make an interactive excel document with all of them overlayed so you can select which ones you want and compare. Would just need all the data and wouldn't be too hard to do, would certainly make deciding which turbo much easier, currently there are too many and deciding is very difficult, mainly as it is hard to compare what is the best, eg peak power, response, power band width etc.

I've done a Radar graph (or what ever its called) to show the trade offs between power, torque, response and drivability. I believe this is more meaningful.

Overlaid results are from:

Standard turbo (some parts are estimated ie. Boost VS RPM on 20psi)

ATR43G3 None FNT (I had a blocked cat on that run so it’s bit under powered)

ATR43SS-1

ATR43SS-1 prototype.

ATR43SS-2

Which demonstrates areas had to be sacrificed to gain in other areas. The goal would be minimum sacrifice for maximum gain.

We can see some combinations are more extreme in certain areas then others. So depending on the most importance to driver’s preferences.

Its also interesting to see the SS-2 is more of a perfectly balanced turbo in every way.

Note. Testing platform, Dyno brand, software and ramp speed must be identical or it won't make any sense. Any one knows how to do this in excel?

This graph is very very helpful, is it distorted Stao? Or is it drawn proportionately, ie equal graphical increments eg. 20kw, 40kw, 60kw or 30Nm, 60Nm, 90Nm etc.. The SS prototype is losing torque to the SS1 and making the same power as SS1? Just more responsive and driveable. I thought it should make more than SS1 but less than SS2. That would be the perfect turbo for me. :cheers: How much rwkw is the SS1 prototype and SS1 likely to make on a R34GTT with usual supporting mods?

Its actually drawn very accurately measured by dots in percentage of the actual reading from graphs earlier, you can work it backwards to get the actual reading from the dynosheet. This prototype is losing torque for better response and drivability, that still needs more work done at this stage, the final version should handle around 280rwkws mark. SS1 should be good for about 250rwkws comfortably on the R34 with supporting mods.

If the final version of the SS1 prototype makes at least 280rwkws with better than factory response and driveability as you say, then it will be KING, no doubts about that.. Go on Stao, put your magic to work, that turbo should sell..

280rwkw seems a touch high with the SS1 Prototype. You are already running 22-23psi above 4500rpm.

The fact that the boost increases as rpm rises would be the reason why the torque does as well.

At least my atr43g3 isn't too outdated! For now...

Haven't even taken it for a drive/tune to see it at its full potential!

Is it on the RB30DET in your ride section? If so, keen to see the response and power it made!

All you need is that red one to create as much torque and power as the SS2 and you will have a golden RB turbo.... but its near impossible to gain such power and maintain response. All turbos are great. The SS2 feels great to drive, for anyone considering it, don't let the graph frighten you. Sure its not the most instant thing off the lights but it is pretty awesome the way it is.

I need moar booooost.

Just wondering if a very responsive 250rwkw rear wheel drive skyline will be able to match a 220awkw evo off the lights..?? And further down the road...:glare:

Unfortuntely not....

Have owned and driven both, I can say its not happening haha.

My Evo 4 when stock was 0-100 in under 5s and 0-200 in 13s. It had 188awkw.

When at 230ish it was scarily fast... I think one of the fastest cars I've driven in an all round sort of way.

      V37 Alarm settings and what the buttons do.

      By HYBRID VL · Posted

      I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models?

      I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again

      Hmm. Was quite a few years ago now. I think I bought from a crowd in the US called CDT Audio. The speaker is the HD-6. The HD-6CF would have been the better option (based on T-S parameters), but they were discontinued in 4 ohm at that point in time. The HD-6 is a better driver in almost every other way (than the CF) - just not as good in IB. They still do the HD-6. They might even have a more suitable (for IB) option here.https://www.cdtaudio.com/cdtnew22/products/components/woofers/midwoofers/midwoofers.htm But, here's the rub. I was working in the US a lot back then, so I got them delivered to my US office and then just brought them back to OZ myself. I don't know if they will ship to OZ, and it probably wouldn't be great cost-wise anyway. As to results. They're driven direct off the rear channels of my headunit, because the headunit can be setup to run the rears as subs. So, not a lot of power being fed there. Nevertheless, there's no shortage of volume - the sub levels don't need or want to be boosted at all. The bass is definitely not what you would call "tight". It is definitely a bit delayed compared to a proper sub. But, with the great front soundstage and really good 6.5" woofers in the front doors, I'm getting most of the bass detail from the front and the rear is really only to extend the bottom end a bit. Works for what I'm doing. I mean - until recently you couldn't really hold a conversation in my car due to the fuel pump, and for many years I had tyres so noisy (Kumho KU36 at <50 tread depth) that I had to drive with earplugs anyway!

      curious to know what drivers you chose and the results? quik mafs, says two 6.5s should roughly equate somewhere between a single 8" or 10" driver. i agree that IB is definitely the way to go in most cars imo.

      Rear suspension upgrades

      By Dose Pipe Sutututu · Posted

      S13 and R32 rear suspension geometry is horrible once you lower it (which everyone does). The camber & toe out ramp is very aggressive, hence it's common for the S13 boys/girls to use a S14 or S15 subframe as the geometry is light years ahead. I'm sure the same can be done on R32s, but I don't know anyone that has done that.
