conan7772 Posted November 26, 2009 Author Share Posted November 26, 2009 Nice work!! Thats very good going, my large can actuator is due to arrive this week Hey Lithium has that box arrived yet. Looking forward to your results after the rigmarole you've had with prv's and ebc's and so on.

JonnoHR31 Posted November 26, 2009 Share Posted November 26, 2009 ok so shipping from ATP is $95 - f**k that!!! Is that what you paid conan? It would cost them $20us max for expressI spoke to MTQ they have a "small can" 19psi actuator there for $135 does that sound like it would do the job? I am getting my car tuned in a couple of weeks and want to try remove every possible weakness before it goes on the rollers RB30DET with internal gate XR6 GT35R currently holding 15psi with the standard actuator but next tune i want to up it to 22psi so thinking I will need the higher PSI actuator What is the benefit of "Large Can" ? i have a spare small can 19psi sitting here tha'll i'll post to you for $134.99. ask mtq to price match that shit Link to comment https://www.sau.com.au/forums/topic/289241-gt3076r-iw-need-help-to-achieve-21-psi-flat-line/page/3/#findComment-4957984 Share on other sites More sharing options...

Haha cheers mate, me too - obviously The big can actuator sounds very promising... though its a fair bit of boost on the stocker RB25! The actuator is coming back from the US with a mate of mine, he actually bought it while he was over there and threw it in his luggage so no freight He left the US on Wednesday so I guess I should be able to grab it this weekend.

Are you trying to say it shouldn't cost $135?

JonnoHR31 Posted November 27, 2009 Share Posted November 27, 2009 na thats about what they cost new. i got given a 2nd hand one for free from a mate because he thought it was a 1 bar, which is what i needed, but turns out its 19psi, bit too much for me at the time.

limpus Posted December 5, 2009 Share Posted December 5, 2009 ^^^Thanks mate... Just out of interest...i'm running a 3076R on a 2JZ (so its similar to a 3076 on a rb25/30)...and i've managed to get the car tuned but its still running the standard small can actuator that the turbo comes with...i've attached the graph of boost response below...it seems to be ramping up to full boost by 3300rpm and holding 18psi perfectly...i was wondering if you guys think there will be more gains in boost response with a large can actuator?

JonnoHR31 Posted December 5, 2009 Share Posted December 5, 2009 take the vac line off the actuator and make sure the gate stays shut then see what rpm you hit the same boost at. dont keep going tho. thats a pretty nice boost graph already tho Link to comment https://www.sau.com.au/forums/topic/289241-gt3076r-iw-need-help-to-achieve-21-psi-flat-line/page/3/#findComment-4972221 Share on other sites More sharing options...

I just remembered that i'm acutally running next to no preload on the actuator at the moment too...i might shorten the rod slightly to see if there are any gains too...

JonnoHR31 Posted December 5, 2009 Share Posted December 5, 2009 ideally you want to run as much preload as possible without causing creep issues. the more preload the less travel so you reduce the amount the gate opens.

limpus Posted December 6, 2009 Share Posted December 6, 2009 ^^^ Thanks...i know that...it also increases the pressure on the flap so it takes more before it starts to crack open... I actually gave the actuator rod a couple of turns today...boost response seems a tad better down low...might keep going a turn at a time till it starts to creep upwards...i guess a big can actuator might not be needed for now...

SimonR32 Posted December 7, 2009 Share Posted December 7, 2009 very nice boost curve there limpus!!! what kind of power you making?!?

limpus Posted December 7, 2009 Share Posted December 7, 2009 very nice boost curve there limpus!!!what kind of power you making?!? Power is very disappointing at the moment...only at 280rwkw at 18psi...this is through a restrictive 2.5" muffler...when I find another exhaust system i'm happy with i'll hit the dyno again for a retune...but at least for now its pretty responsive for a daily...

Lithium Posted January 25, 2010 Share Posted January 25, 2010 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 Link to comment https://www.sau.com.au/forums/topic/289241-gt3076r-iw-need-help-to-achieve-21-psi-flat-line/page/3/#findComment-5054495 Share on other sites More sharing options...
