Sharing a couple of results:

This is the recent SLSS2 run based on a Stock Rb25det with injectors, Brae high mount and 50mm gate on E86 final run or 356rwkws @20psi

ATR43SS2 None VCT E85 Bolton version internally gated on factory exhaust manifold

21U R33 high flowed turbocharger 265rwkws on P98 fuel, running factory actuator. A high pressure actuator has been installed, looking forward to updated result.

talking about turbos coming loose a few pages back, anyone tried the atomic Anchorlox yet?

cheers

First I'd heard of them but I don't see them being any better than ordinary locking tabs, aside from the fact you can reuse them. If anything they look to take up a lot of space.

Anchorlox look promising, price is high. GCG offer the same gear for more acceptable coin. The nuts and Belleville washers available from Ralliart for the Evo are top notch but also priced accordingly.

That SLSS2 setup looks to deliver far more linear than the ATR43SS2.

Boost plots are way different which would account for the mid range torque whack the ATR43SS2 provides. Maybe the Brae manifold flows much nicer up high because it's like the thing isn't being strangled? Keeps making torque past 6000rpm.

How do they compare for real world driving and response?

Also, will eventually have results for my old SS1PU on a mates car now. He put it on his stock motor S15 with an external gate. Am not sure if he plans to run cams but he should beat my result due to the gate.

Preliminary testing indicates with the VCT he has not noticed any loss in spool (no extra lag to stock), and on 10psi he has already started gaining power vs the maxed out T28 that was on it prior.

I will update for records when available.

The SLSS2 is designed as an externally gated turbo, that particular reading has the advantage of external gate and Brae manifold, they do stretch power and torque figure a lot further. On same platform, they performs very closely as they all have identical compressors.

Unfortunately most of SS2 results shown are running as stock boltons. It also appears that Neo motors, probably due to their cams, they can fetch power and torque further into the high PRM regions compare to standard R33 Rb25det motors.

Notice the behavior of this is a Neo motor with a bolton SS2:

Result could be from E85 as the tuner has forgotten.

That SLSS2 setup looks to deliver far more linear than the ATR43SS2.

?

Yeah i would say the dofference is in the manifold and ext gate as i run the atr43ss2 also with brae mani and ext gate and my curve is very similar to that SL curve.

Anchorlox look promising, price is high. GCG offer the same gear for more acceptable coin. The nuts and Belleville washers available from Ralliart for the Evo are top notch but also priced accordingly.

thankyou for that information, the stage 8 stuff from gcg is a a lot cheaper

The minimum amount of boost I run on the OP6 turbine was 19psi and that was 320rwkws on E85, internally gated. details are at:

Woohoo, it's in! Loving gate atm, just running 0.5 bar at the moment till I work out what ecu I get. Will hack up the stock shield tomorrow and heat wrap the screamer, it's a tiny bit loud lol

Patience hahaha, I will :)

Spent today tuning my mates S15, made 197kW on Mainland dyno. Stock turbo and the works, I've talked him into a SS1.5 in a T2 flange. He might so it soon :)

Thanks for that mate

Can't wait to get everything sorted so I can send it off to you for a high flow

Got my R34 OP6 turbo here waiting for a visit to Stao, looking forward to seeing your results. Which profile are you going with?

Just the standard high flow profile.

Currently have a SS1PU on my 33

But I want the 34 to be looking as stock as possible so that I don't get any attention from the po po. It will be running on an adaptronic with flex tune

Actually that's a good question.

What would be the benefits of a SS1PU over a high flow on a standard 98 tune?

Back in the day it would have a better top end but now days the high flow seems to be getting better results.

As you know I am a major devotee to the thread and product (even though I'm not personally using one anymore), and in my opinion the current highflow is one of the best options available.

I would buy a 2iu highflow over an SS1PU, and I would buy an op6 highflow over an SS2. Internal gate, bolt on.

I would go the SS2 if I was investing in the supporting mods to aim for 350, but not otherwise.

    • Hard to say, just pop the rocker covers off and have a look if you think it's cammed. You probably need to replace the valve cover gasket/half moons anyways.
    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
