I have got my hands on the latest release from garrett.

i need a 25mm spacer between the turbo and the manifold,

and i need to fabricate a dump pipe but apart from that everything i had for the gt30 will plumb straight

in. I picked the .82 a/r so i will be very interesting to see the results.

here's a couple of pics. looks good

sorry

i just checked and my bad.

8mm is the dump flange bolts.

the t3 base bolts are 10mm.

and yes once it is spaced away from the manifold there is heaps of room.

i will start taking some progress pics when i get home from work.

Is this the internally gated T3 housing that Garrett have been promising all year, and part of last?

What is the used unit beside it? It appears to have a Garrett logo on the compressor housing too.

And most importantly, can you post up the CHRA ID tag number too please?

I'm going to be interested in the progress pics.

cheers

Yes very interesting , hope they are available in quantity !

Dale the CHRA number would be the same for any cartridge with the same comp/turbine so its the complete assembly or unit number you want . Something worth noting is the part number stamped on the side of the exhaust housings mounting flange in the second shot . This would almost certainly be the turbine housings part number .

What I want to know is can these housings be grafted onto the GT37R cartridges because they have the potential to be better than the GT3540R cartridge for the larger/est RB - just need a suitable exhaust housing .

Cheers A .

Awesome news!!!!

Out of curiosity.... :(

Do they have a .63 internal gate gt3540?

Hi all , I got to look at a couple of these this afternoon - yep .63 and .82AR ratio .

The Garrett part numbers for the housings themselves (according to the packaging) is 771300-5 for the .82 and 771300-6 for the .63 .

The waste gate flat valve looks to be the same size as the IW GT28 housings and there is room for a larger disc as well . Doing a "high flow" on this valve is common practise on souped up XR6T's so no reason why these could not be modified the same way . BUT - always that but - the greater the area of the disc the more area exhaust manifold gasses under pressure have to work on to try and force it open . I kid you not and don't laugh , I've seen people using what looked like old bed springs trying to keep this valve shut .

The rule is if you run high boost pressure do everything you can to have the exhaust manifold pressure down somewhere near inlet manifold pressure . You don't need massive exhaust manifold pressure to drive the turbine just sufficient gas velocity by thermal expansion .

Back to those housings , Brett at GCG has I think five of each AR size ATM so be quick if you need one soon . Had I been better organised I would have had some pics but no doubt they'll turn up .

Cheers Adrian .

      Borg Warner EFR Series Turbo's V 2.0

      A few things that seem a bit off here. - why is there 2 BOV’s?  - the turbo smart BOV on the compressor housing, is it turned up ALL the way? I have seen this become an issue on old man Pete’s car. It would push open and recirc, turbo speed would rise and the boost pressure would do weird things. - stock head? Does that include springs? - tried a different MAC valve? Is it plumbed correctly?

      Photo of manifold showing gate location? I mean, it's 6Boost, so we probably shouldn't be worrying, but always wroth knowing what the layout is. Plumbed back to atmosphere? Or into the dump?

      Yes correct. Also, I'd avoid applying it to soft paint (however I doubt you'll ever have to deal with it in practice). So any paint that hasn't fully hardened, could be a 1k paint that never fully hardened or it could be a 2k paint that was laid down thick and hasn't yet fully hardened.

      Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging. Cheers
