Anyone see the press release on the new Garrett G 25-550 and 660 turbos? The 550 model is essentially the GTX 2860 gen III. Higher flowing hot side and a new compressor wheel rated at 550 hp at the crank a piece. Should be great for up to 1000 whp with excellent spool. Looks like it has a stainless exhaust housing and some other nice new features as well.
