No its just all air cooled under the bonnet. We were playing with it few weeks ago and didn't notice the vacuum hose. It now has also picked up some thing like few hundred rpms of response. :D

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

Sounds good :yes:

These truly are the turbos built perfectly for our motors. I usually run 14psi all day every dsy with my ss2. Yesterday I wanted to test if the knock occurs on high boost and if it occurs earlier. I cracked out 18psi. My god this thing is brutal and it was on a slight uphill road. I remember after jez tuned my car we drove around on low boost which felt nice and strong plus better than my old tune. We kicked it into high boost and shit went off. Ive been in a r33 with a gt3582r and I can tell you that the ss2 dominates in every which way. Response, power delivery and driveability. You also dont need to run such high boost to achievr this. My old tune was 10psi and was making 244rwkw. Not many turbos will push that out of an rb.

What gate type and how do you have yours mounted Sarge?

Little update. To make the SS3 even more responsive I've had it remade using ceramic roller bearing cartridges instead of steel. With the vacuum leak repaired this turbocharger is super responsive, It has made a very fast car. Can feel the turbocharger whistle to boost with touch of throttle and goes blastic as it revs out. Made me thinking, wither if the SS2 BB VNT should be more responsive without that vacuum leak.

I've taken a little shutting down video footage from my SS3 VNT CBB turbocharger, as you can see this is a very big turbo, 394rwkws on E85 is not a real lot for some thing in this size. Goal is 20psi by 3500RPMs, Its going back for a return next Tuesday, and I'm very positive about it.

Will be in process of building a SS1PU using VNT system. Pretty confident it will match or beat HKS 2530's response while making same power as a 3071. This will bring some joy for RB20det owners.

How far off ready to sell are the VNT turbo's Stao? Might be interested in a swap/buying a VNT turbo if they arent far off and it will work on my setup. They look like an insane power/response combo. At the same time though I still want to see what the SS2CBB will do as well. Can always upgrade later anyway :P

.Can run a ATR28SS1.5 that should be a more responsive version of the GT2871

I have had a look for some dynos of this with a sr20 and cant find any have you got any handy?

What type of power can this one do?

I want to fully explore the potential of the new idea, and find a way to manufacture those at affordable pricing.

Don't have SS1.5 on SRs at moment. only have it with Rb25det which is super responsive.

I'm wondering about this too. Currently the ATR43-SS1PU – which I believe is an FNT unit – looks like the most interesting option for what I'm after.

Is there going to be a 'ATR43-SS1PU-VNT', and how would it potentially compare to the current unit?

Or, could you possibly go a bigger profile e.g. SS2 with VNT and still achieve a similar response as with the current SS1PU...?

Figured there must be alot of R&D yet to come. I'm sorta keen to see how good the SS2 goes anyway, so I'm sure I can swap later on down the track :P

lol SS1PU VNT on an RB25?? Boost on idle lol

I think an SS2 VNT would be more rewarding on an RB25 :)

Something around 350rwkw with full boost at 3500rpm or lower would be amazing. I'd love to feel a high power VNT setup, must feel amazing

SS1PU VNT, prediction is 20psi by 2800rpms and maxing out at 320rwkws. The external gate will be screaming all the way. might be able to make it run internally gated, more tests will be carried out.

This sounds fantastic. Any thoughts on timeframes as yet?

Next week I will be finalizing the tune on the SS3 so probably the week after. At moment the problem is manufacturing them at affordable cost, I don't think its reasonable today to charge some one $2500 for a turbocharger regardless how good it might be. Unless its made out of gold.

that's awesome! 300+kw and more responsive than a standard turbo.... nice

certainly come a long way from my OP6 highflow on my GT-T, well done mate :)

could VNT fit/work in a twin low-mount setup on a RB26??

currently running 2 x HKS 2530s... not sure if some frankenstein setup could be made of current turbos?

      GOT SUM's RB34

      By klutched · Posted

      Did a little bit this afternoon and pulled the dump and turbo off so I could take the mani off to clean it up and give it a few coats of paint. Wire wheeled what I could get to and then got the sand paper out to get the tight spots. Gave it one coat so far, will do another two tomorrow and see if I can fit it in the oven to bake it for an hour along with the adapter and dbw.  Hoping the exhaust wrap I ordered turns up soon so I can wrap the dump and screamer. Ordered 30M so I'll wrap back as far as I can to help a little with temp next to the box and also the floorpan.

      Rb26 expected power

      By dodo1410 · Posted

      Yeah I think overall I’m running the expected power I should be running for now and I’ll just enjoy it for the time being until I get some other parts. Thanks for the advice mate I appreciate it!

      By Murray_Calavera · Posted

      That's fair enough.  Might be time to just enjoy what you have until you sort the ecu/flex sensor situation. You can pretty much guarantee that you are knock limited and e85 is going to be the solution to more power.

      He didn’t provide that info to me but I think I’m on standard timing. And no we don’t have e85 on the petrol stations here but it’s widely available here from shops. I’m just planning on getting a better ecu before switching to e85

      Seems bang on to me , g30-900 will make 900 crank on e85(on paper). Deduct ~25% for 98 and you are at 675 crank. Run that to the wheels and fact you are only running 26psi you end up about your number.  People forget how magic E85 is now that just about everyone is running it.   "Back in the day" you had to be north of 30psi on a 850+hp turbo to get 600 at the wheels on 98.
