Avcr And The Actuator

Can someone confirm whether or not when you use an electronic boost controller, does that negate the differences between using rb20 vs say rb25 wastegate actuators.

I remember reading once that the difference in is like 7 to 10psi or so though if you use say an AVCR it nullifies the advantage in sticking with a rb20 actuator.

RB25 wastgate act. is 5psi, RB20 is 10psi

Changing to the RB20 means the AVCR doesn't have to work as hard.

That's the theory anyway, don't know if it makes any difference in the real world though.

Just use whatever you have and go for it.

If you wanna change actuators later, it's only a 5-10min job anyway

..so the answer is yes, you should get close to the same results with either

Cool.

well i have both actuators, and i know that using the rb20 one does give a significant increase over the rb25. however i've heard the AVCR does all the work and the rating of the actuator is irrelevant.

anyone else?

If You only wanna run 12-13psi, go with the 5psi rb25 actuator, to give the AVC-R more control. If You wanna punch more into it, go the 10psi RB20 actuator so that it won't crack the wastegate open until 10 pound. This'll help quicken spool-up, by not bleeding any gas past the wastegate.

The AVC-R will start tweakin the solenoid at 0.3 bar regardless, so I doubt it'd affect how hard it works, only the duty cycle.

In otherwords, he's saying read birnies post :D

at stockish boost levels, I found that changing actuators with an ebc didn't really do much in terms of spool time. What it did do is it made it hard to make it slightly over wath the actuator is rated to e.g. with the r32 actuator (11ish psi), it was harder to run 12 psi than with the rb25 actuator.

      GReddy Injector Help!

      By GTSBoy · Posted

      Unless there's something particular about the Greddy manifold's injector holes that I'm not aware of, those injetcors look to be totally wrong. They would absolutely want to be spaced up to get those long snouts out of the runner. Which, I think, is not usually the way that that problem is solved. I think the problem is solved by using the correct injectors, which would be much more like what Andrew posted.

      Thanks for the reply, So i've continued playing around, and fitted the injector adaptors onto the injector, the fuel rail is not able to be mounted now as the injectors sit a bit further out. I suppose the point of the adaptors is so that the injector nozzle isn't so deep into the intake? I suppose 1mm extra on the o-ring would do it but still can't mount the rail onto the intake haha. Waiting on a reply from Aeroflow I'm sure there's something stupid that I'm missing...

      GReddy Injector Help!

      By TurboTapin · Posted

      I have a radium fuel rail on my Greddy manifold and used the supplied radium fuel injector to manifold adapters (The round green things pictured). I did always wonder if you could just go ahead and use the second lower hole like you're doing... Wouldn't thicker o-rings solve your issue?

      Does anybody use the Firestryker or Element sticks?

      From what I've seen and experienced first hand with those powder extinguishers, they're good to use to break a window and escape the car, and half the time then do f**k all to stop a fire. You just need much more than 1KG worth of powder. Not to mention, half the time it's an engine bay fire, and you can't easily, and do not want to completely open the bonnet, so you're left pretending to be an American Infantry... Spray and Pray baby!   And then 100% that shit is really destructive afterwards!   Realistically, those little ones at a race track might help you keep the fire from growing and give the fire marshal / truck a chance to actually get to you with their multiple large bottles.   For a road car, these days, prepare to deboard as quickly as humanly possible, and move to safety. Allow insurance to fix replace it (unless it's like a rare classic etc, then do nearly everything possible to save it!) Keep the little extinguisher with you to help protect other things around you from burning while you stand there singing "How can we sleep while our beds are burning?"   Secondly, powder extinguishers I freaking hate for indoor use, (this isn't really relevant to a car) as you will get a powder fog around you, and it can be disorientating.   When I did fire training when at BlueScope Steel, they have (had?) their own fire brigade on site. We did all the training, and at the end we were told, "If it's an indoor fire, and you need to use a powder extinguisher, we as the fire brigade would rather you just exit the building, you're more likely to get lost in the smoke and powder fog than do much help, so just GTFO" And pretty much that was what they said for most other fires too, grab extinguisher, if it's much more than paper in a bin fire, use extinguisher to get you and others out of the building to safety...   Part of me wishes when my Skyline caught alight many moons ago, I let insurance sort it out, instead of putting the fire out... part of me now says "But I've saved a classic before it was a classic!"
