This Dual Ball Bearing turbo has an Oil & Water Cooled center cartridge. This is a 950hp turbocharger with a billet compressor wheel. This turbo makes more power, and a better powerband than the previous GT4294R.
Garrett's ball bearing cartridge has proven its worth in the highest level of motorsports where it has been the bearing system of choice in CART FEDEX ChampCar Series, 24 Hours of Le Mans, Pikes Peak International Hill Climb, World Rally Championship, and most recently Drag Racing. These premier racing customers demand no less than the best in durability, reliability, and power on demand. One key contributor to this performance lies in the ball bearing cartridge where it is, by design, surrounded by a thin film of oil. The oil film damps out destructive vibrations that would otherwise compromise turbo durability.
