Also ATR45 AKA ATR43G4 turbocharger on same car using same mods making 431rwkws @ 26psi. Not a responsive turbo, but super strong mid top end power and torque.This turbo should be able to pull some reasonable quarter times.

ATR43 SLSS2 Turbocharger

Got this tuned today. Big thanks to Status tuning as usual.

Just out of curiosity of what the 10cm L2 turbine can pump, We tried every thing to squeeze power out of and The maximum we've got it to was 385rwkws on 24psi. The car refused to make any more power after this.

At 22 psi it made 374rwkws so basically identical to SS2 at same boost level.

This goal of this turbocharger is to make better power then a T67 while having the same response to a 20G.

I've overlaid three readings from:

Our brand new SLSS2 turbocharger
V
Latest SS2 turbocharger that has the identical compressor setup on lower boost level.
V
The highest reading of a T67, Greddy manifold, externally gated.

All on Rb25det with stock cams.

Hey Guys,

I have been slack lately and didnt post the results, i WILL get Dyno sheets soon but for now -

Car made -

311rwkw on pump 98

320rwkw on E70 at gate pressure of 1 bar

340rwkw on E70 at low boost of 18-16psi

357rwkw on E70 at high boost of 21-18psi

Full boost at 3900ish

The dyno run shows 360.7rwkw which was its highest run but it was having fuel supply issues, it was retuned safely to 357rwkw where it sits now. The turbo and exhaust flow are basically on their limits.... to go higher i will need to do the clutch again, more fuel system upgrades and a bigger turbo, its so nice to drive now that any more would just spoil it.

Basics that got me to this level -

RB25 NEO stock internals

Garrett 3037 - 56T 0.82 rear

6Boost manifold, custom dump into 3"exhaust (Very quiet)

Tial 44mm MV-R with screamer or plumb back setup

Plazmaman Pro Series Thottle body/plenum/cooler & piping

Xspurt 1000cc injectors

HKS fuel rail - 6 fittings and 3/8 line i think

Bosch 044 pump, Sard Reg, Billet filter

Haltech PS2000 wire in with ethanol sensors and wide band (Full Flex tune by JEM)

HKS EVC 5

HKS Exhaust Cam gear and full Gates Racing timing belt kit

Tomei type B poncams, Performance valve springs and retainers

The list keeps going, but i just realised all this info is in my Signature Cost heaps to do but it an absolute dream to drive daily and is a laugh on boost!

Dyno run on E70 -

So as impressive as this result was last year we have decided to improve it, we had an injector issue which required them to be replaced with the new XSPURT 2000cc items, due to a full flex retune being needed we decided to improve the spool and power too.... TS was initially the plan BUT then we decided to go left field and try a new turbo, instead of trying to make old tech work better I decided to take a punt with a new billet item and well the results need no further explanation -

yeah i said dont go over 320 so he put 20psi on it and said it is nice and solid and safe

starting to think i should turn it up - but head and block have not been touched and injectors are at 85% -

car has been off the road for so long so just wanna drive it and enjoy it and start throwing it round the track..

Any restrictions here? With your setup on e85 id have thought it would have pushed closer 350rwkw+

Nice, probably a good way to go about it.. Standard bottom end would hold up under a bit more too i reckon.

Ive got standard bottom end, head has been port and polished, apr head studs. GT3076 making 450rwhp on 25psi. which is like 335kw i think. On E85 also

[Reese69]

nice..

with the luck i have had with this car i just wanna drive it lol and i wanna start drifting so i think that will be good enough power - i have rb 30/25 ready to be built so just need the current motor to last while i buil lol - good thing was my tuner was confident it could do more but best to be safe i guess.
