But it looks like Jesus in the background!! Oh wait.... nm...

^ I think you'll find that pic is in Australia....

Next step in this saga, I am now another happy user of the big can 1.2bar actuator Well at least so far... Installed it and took it out for a blat yesterday, and with my pressure relief valve and AVC-R completely removed from the picture I was still reaching 1bar by around 3700rpm - which was impossible with the old actuator without removing the hose. I turned the AVCR on and set it to 1.1bar, and I am reaching full boost by 3600rpm without relying on the pressure relief valve - and as a result I don't seem subject to the big random spikes I used to get with the PRV. Very happy with this, feels much more consistant in power delivery and probably safer - it does appear to have a SLIGHT 1psi fluctuation as it comes on full boost but I would guess this is normal. So, so far so good, next stop... dyno tune

Another happy user of the big can actuator, here Well at least so far... I took it out for a blat yesterday with it connect, and with my pressure relief valve and AVC-R completely removed from the picture and preload wound right down. With it like that, it hit around 13psi peak which was nice to know. I then wound some preload into it to get it up to around 15psi, and this is where things started looking really good. Without any extra boost control I was able to reach 1bar by around 3700rpm. This was impossible with the old actuator without removing the hose! I decided to leave the messing around with the boost control to see if I could make it climb to 16-17psi with any stability (I couldn't reliably with the old setup) for the morning commute, which resulted in me being able to give some words of wisdom to others who are bad in the morning. DON'T replumb your boost control setup in the morning if you are not a morning person. My vacuum hoses are too short to reach from the AVCR solenoid to the actuator now as I split them to put the pressure relief valve in between. Because I wanted to play, I just wound the pressure relief valve right down (I triple checked I was winding it the right way, and I was) and used it to join the hose so it could reach and all seemed well. I went out and gave it a quick squirt - which resulted in this: Oops. Nothing departed block or anything, so hopefully no harm done - in theory I have a boost limit of around 18psi so the rest of it should in theory have gone into the plenum but not joined with any fuel to make bad stuff happen. Still a bit of a fright though! I went back to the engine bay and remembered the pressure relief valve (unlike regulators) have to be aligned with the airflow, otherwise it will be permanently closed. My bad. I spun it around the other way and went for a slightly more tentative drive, and to my joy the thing seems to spool every bit as well as with the pressure relief valve in there - but once full boost is hit, it holds much more consistantly! So far so good, next stop... dyno tune

Crack yourself up? We have a NI wasteland area - if you need to spam NZ threads with your stunning Australian wit, put it there. Ta.

What do you drive, and where in the country are you? I'm a Wellingtonian, drive an R33 GTS25t with a very giveaway licence plate. I know there are others here...

Oh thats quite nice

Big can actuator is going on tomorrow, tuning will be when I can get some dyno time

Yeah bro, live right by the beach! We often like to go down and eat fish and chips, its sweet The import laws here are really tightening up unfortunately, though that was after the Japanese cars started getting boring... so we got flooded with all the cool 80s and 90s ones.

Other way around...

I'm the sole NZer in this thread, and hardly feel mocked lol. We used to watch Ignition DVDs from Oz and spend half the time cracking up, the accent and culture thing works both ways. In saying that, it doesn't exactly make it feel very inviting providing NZers with their own area and then making it a take the piss out of NZ area seeing the actual whoretown thread says Unnzud. A bit of jibe here and there, but I've never heard a NZer called NZ "Unzud" so thats clearly gotta be fixed

Australians have all the best sheep pics...

Tease! <does up belt>

A/R is NOT trim, they are two different things.

Check highlighted above... and the turbo in this link: http://www.atpturbo.com/mm5/merchant.mvc?S...tegory_Code=GRT

Very interesting, good luck with that! I'd personally not want to push a GTRS that high - especially on pump gas but interested nonetheless in the results

HKS GT-RS on 20psi on an RB25? What kind of power at that boost level?

How much boost are you running ^

Hopefully when I get mine on the dyno, I'll be able to tell what mine makes at 4000rpm haha

Well I personally wouldn't recommend looking at running anything smaller than a GT3076R for that kind of torque - off the top of my head you'd need substantially over 1bar of boost to do that, and any turbo smaller than a GT3076R at that boost level is going to be getting quite inefficient at the higher rev ranges when trying to pump that kind of air.... you really don't want to be running a street/track car beyond the efficiency of a turbo on the track if you want the engine etc to last.

Was that a typo, or do you think you can make an Rb25 car faster on 250kw with a different turbo to an equivalent 300kw GT3076R setup? Don't get your hopes up too high on that one.

If its not a secret, what do you run on it?

Awesome, good luck

The PE RX6R is a bit of a different beast to the typical IHI/Apexi RX6s... its almost like comparing a GT30R with a TR30R. Angus Smart - that'd be awesome to see. One of my friends have an R32 GTR with a GT4094R on his built RB26 but he needs to sort the fuel system out... its still on the stock one while he sorts other things out and the thing hits 300wkw by 6000rpm on wastegate boost, and the thing is pretty laggy with that small a rev range haha.
