From Garrett Gearheads I hear Garrett is releasing a new series of compressor wheel or turbo called GTX-R . The spiel is that these compressors will be able to pump 10% more air and handle 10% higher pressure ratios (boost) . A couple of people think that it's big G's answer to extended tip technology .

The only pic I could find loks like this . Note 11 blades and all full height , no splitter or "half" height ones .

Cheers A .

Um also Garrett claim they have fixed the swing valves twin integral gate system on their Evo 10 twin scroll GT3076R's turbine housings .

Actually that 10% more I forgot to add means 10% more than the same sized GT compressor wheel . I think someone mentioned that they are a wheel machined from a forged billet of aluminium which is the economic way to get them into production . If possible they may cast them later .

Versions mentioned (nothing concrete) may be a GTX4088R , GTX4094R and I think a GTX42R and GTX45R .

Cheers A .

Interesting, not quite sure which models those turbo's will apply to above :)

It would be great if they bought out some new GTR turbos before I get around to buying them (which is going to take forever, lol)

This is excellent to see!

Now we here in australia will be able to get our hands on this technology that the yanks have had for quite some time!

Go's to show that borg warner, precision etc knew what they were doing :)

Glad to hear it! That should put garrett into the lead performance wise for a while. I wonder if they will charge a bunch more for these, or lower the prices of what they already sell and price these similar to what's out there now.

you can see the machining marks in the wheel. wow! billet wheel is pretty cool. the tips are on quite and angle. they look like the hx35 compressor wheels any specs on weight?

SEMA has come and gone. No new info on the net.

I've got a mate who's very keen to replace his twin -5's on a JUN 2.7 RB26 with something a bit bigger. I'm thinkin a GTX4088R twin scroll 1.06 would do the trick.

Finally there will be no denying that Garrett has a T04Z KILLER!!!

Anyone got compressor maps of the GTX turbos?

Personally the only biggie there is how quickly you could get your hands on a std GT4088R , technically speaking it has it all over a T04Z anyway .

The road to getting a 4088R to work is via a really good pulse divided manifold and probably two external gates .

Where they are better off than most GT wheeled turbos is that the trim sizes have come down and that helps them to be responsive things in their size range . If they did the same thing with a GT4294R it would be more responsive and closer to what a T51R BB can do . Lets face it the T51R still uses ancient water pump tech turbines but in 76 trim they are more responsive that a better aero tech GT42 turbine in 84 trim . So a GT42 turbine in 78 trim ...

Why? Because they make comp wheels out of billet? There's more to a turbo than the compressor and Garrett have always led the way in making an all round high performing turbo that's RELIABLE.

Borg Warner know what they are doing as well but Garrett as a company were waiting until after the economic fallout before putting this all into production.

I would always pick a Garrett over a BW.

You can bet they will be more than 10% dearer

Why would anyone pick a 4088 over a Z when the 3788 has the same comp wheel as a 4088 but smaller turbine?

The 3788 would still be a better choice for response

impressive to watch to

that is awesome watching how they sculpture an item from a block of metal - billet process is very impressive & reminds me of OCC (oraneg county choppers) when they make their billet wheels

Looks good so far:

I compared the GTX4294R with a GT4202R compressor map - the 94R has more everywhere, awesome!! Here's hoping they spool like the GT4294Rs.... that could change things quite a bit.

Thats an impressive looking map, garrett answering some of their competition perhaps. Some real world examples will tell the story. Hopefully sooner rather than later.

Is there any news on smaller frame variants taking advantage of this setup? Or are we talking cost out weighing the advantages?

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
