Jake and Charles are going on the basis of how many DIY installs come to grief when compared to those done by someone with both knowledge and experience. Very early on, judging by the number of phone calls we got from some pretty distressed car owners, all of Charles and Jake's efforts to make the install as idiot resistant as possible was not working, as it became obvious that God had sided with the idiots. We got calls from people that had no idea they needed to lock the cams down with the engine at TDC before pulling the IMS flange off; calls from people that tired to bump the engine into TDC using the starter after removing tensioners and the IMS flange; and I don't know how many calls from people that had just shut the car off and pulled it apart without locking down anything, only to now find that the IMS shaft was off to one side and they could not install the new bearing. My personal favorite was the guy who had actually suffered an IMS failure, had an engine full of metal, and still did the refit even after multiple experienced installers told him not to do it. Once back together, the 996 did not make it another 20 miles. And in every case, the car owner somehow found a rationale to blame Charles or Jake for their problems. I can't imagine what Jake and Charles call logs must look like........
Charles and Jake are small business owners, they do not have a huge staff to take product support calls all day long. Yet they tried to help all comers when the installs went bad; which quickly became an all consuming effort that left little or no time for anything else. Based upon this history, I can full appreciate why they have moved away from the retail sales market for these products; relatively few "professional" installers had problems, and those that did were willing to spend what was necessary and learn what their mistakes were, and how not to have the same issue again rather than arguing that the product/installation instructions/tools/procedures were at fault. And based upon the number of successful refits done since the products were introduced, there is nothing wrong with the system Charles and Jake created. But basic human nature found ways to make it not work.
Single row bearing car are the largest "at risk for a catastrophic IMS failure" segment of all the cars produced. The Pelican system is basically a new OEM bearing on a stronger center bolt (the OEM bolt can and does fail). Worse yet, the Pelican system replaces an OEM dual row bearing with a single row and a spacer in engines that were OEM dual rows. Yikes! Why you would want to take out a bearing because you had no way to predict when it might fail, and then replace it with another one with the exact same potential for failure is beyond me, much less to replace a better bearing with it. The cost argument simply eludes me; your $15-20K engine, not to mention the resale value of the entire car, is riding on that one part. Why wouldn't you spend just a bit more to get something that is proven to work better (LN ceramic refit), rather than a product little to no proven history and a very limited installed base? Just to save a couple bucks? Someone is always going to copy a successful product with something "almost as good, but cheaper", but that "almost" can quickly come back to haunt you........
