Here is what Precision has to say about their history: Most are run at insainly high pressure ratio's and shaft speeds and for them to last as long as they do is a testiment to their engineering. While some still claim that precision is suffering from reliability problems one needs to remember that people are not buying a precision turbo to be gentle on it. They hold over 200 records and are making horsepower numbers at high boost pressures that have never been seen before. I would not hesitate to purchase a precision turbo now. What changed? Who knows for sure, but its safe to say that they found a good supplier, or started doing more quality control testing before shipping out units. Their popular turbo’s like the 6262, 6266 6562, and 6766 have been performing GREAT and lasting as well. SOMETHING happened at precision and they appear to have gotten their acts together. Also, they had never designed there own turbine wheels before, just comressor wheels, so they reverse-engineered/borrowed the turbonetics designed turbine wheels for the first production runs on some of there more popular turbo's.Įnter the 2010 era. Because of this Precision turbo’s got a bad reputation. I am talking about the CHRA center with its shaft, bearings, cooling channels, and seals. Also it was there first time making the inner guts of a turbocharger. I would assume that once Garrett cut them off, they had to bring products to the market faster than they really should have. Failures were all over the place, and there is no shortage of stories on the internet about it. As one could assume with a new company there products suffered reliability problems at first. Precision then moves on to make there own CHRA center housings and continues to supply their own wheels and housings. Garrett then cut off precision as a supplier. We have all heard the saying: “you shouldn’t crap where you sleep”. You would have to assume Precision as a company knew what they were doing. As you can guess Garrett wasn’t happy about that. Then they started to modify Garrett turbo’s and openly advertise how their turbo’s were out performing standard Garrett turbo’s. They would take Garrett turbo’s and resell them, mainly focusing on the aftermarket scene. Precision is a company that up until recently was really just a distributor of Garrett turbo’s. Lets take a quick look at the history of each company. Knowing more about each company will probably help you more in your decision. Each of the companies offers many turbo sizes, turbo housings, internal wastegates, just oil or water cooled, and journal and ball bearing versions. Each manufacturer stands behind their product and is really good about honoring returns for units that have failed. The reality is that they all make great units. The answer is, whichever one you think would work best for your set-up. Borg Warner Turbochargersĭo any quick search on the Internet and you will find that car forums are plagued with the question of "which turbo they should buy, and from what company?" The goal of this article is to try and give you a background of each company and talk about what really matters when selecting a turbo as well as who to buy it from. Kopia seems to be as fast or faster than Duplicacy, with a significant advantage in size, and also number of file chunks created (88 files in kopia repo vs 1822 in duplicacy repo).Garrett Vs. It was run on a Debian 11 VM, 16GB RAM, 12 CPU in VMWare Workstation. This was not a rigorous benchmark, just a quick test.
