The new Garrett G25-550 turbo
 

Search didnt show anything. Has anyone tried a G25?

Looking at the specs it should be something that wants to compete with Borg Warner EFR's.

I tried a local shop but they haven't heard anything on pricing yet.

Anyone have any thoughts/Opinions? I feel like Garrett hasnt done much to compete before this. The GTX line etc was a meh upgrade at best

2 grand
hard pass lol

Full Race has some info on it. I honestly really like Garrett and have always been loyal to them. Will be interesting to see if they outperform the EFR line which still hasnt blown me away honestly.

I bet garrett loves blind ignorant loyalty.
just like Hydra

In the past Garrett was the mack daddy, I have never once had a garrett turbo fail on me and the results have always been extremely good. My turbo kit came with a Hydra so if it works why should I replace it? I guess I could blow 1200 on a MS3 but the Hydra works so ummm....?

Garrett was never the mack daddy. Garrett just had a near-monopoly on the market and had almost no competitors. Now that the market has some diversity, they are falling by the wayside, and attempting to step up their game to stay competitive.

I don't see this as a strong enough effort, and would never dumb 2 grand to find out, when you can spend hundreds less for a proven winner.

Saying "they aint neva dun me wrong so they legit" is not a valid argument when discussing new innovating technology.

In my opinion Garrett has been the best. We all have our own opinions though. Still will be interesting to see how the "G" series turbos perform.

I haven't really heard of anyone living the efr. It's fantastic on paper but never really puts down the numbers.

$2k is crazy. Guess that ship isn't leaving port..

In unrelated news ... 427wtq 6758 Miata

Holy shite!!

I don't think the G-series are actually available yet, are they?

It will be interesting to see how they stack up against the EFR. On paper, it's got the same performance advantages over the existing GT/GTX turbos.

:rofl:

They didn't have models at SEMA, just leaflets. AFAIK the turbine wheel is still nickel-based, not Ti-Al like the EFRs. To me, the turbine wheel is why the EFR works the way it does.

I'm not an ME, but the guys at moto-IQ seem to be excited. Supposedly "Mar-M" for the turbine, whatever that is.

andy, welcome back, but seriously stop posting like its still 1996 when you were last here.

Mar-M-247 density 7.8g/cm3 (Garrett G-series)
Inconel density 8.1-8.4g/cm3 (depending on alloy)
Gamma TiAL density 4.0g/cm3 (BW EFR)

A dyno plot is............get this: putting down the numbers, LITERALLY ON PAPER.

Who knew, right?

Rough estimates of maps overlaid; more expensive for maybe a few more peak power? And with turbine metal density nearly double the EFR....no thanks.

It's good that they are trying to compete with the EFR lineup, but considering the price differential I still maintain the EFR is by far the top dog in the turbo world right now.

So far I've only seen one place that's posted a price that's anything other than an obvious place-holder, and that's full-race.com, and their prices on all Garrett turbos are significantly higher than other vendors. IIRC EFRs were stupid expensive when they first came out too, but prices came down a bit. I think it's a bit early to be passing judgement on price/value. :)

As for the inertia of the turbine, the moto IQ article has some interesting things to say about the design of the compressor wheel and the fact that even if the density of the turbine wheel material is higher, the strength is also higher, implying it could be made with less volume of material.

Let's see how it does on an actual engine before pronouncing that it sucks, huh? If nothing else, I'm glad to see Garrett bringing out new products. Competition is good for everyone.
