Message: <blockquote data-quote="Raptorsc" data-source="post: 1362412" data-attributes="member: 17615">OK I will quickly put up some factsCentrifugal compressor design started in 1800's, however Raptor is new techology in many respects, you could say it is refinement of design. The ceramic ball bearings, the high efficiency impeller, compact scroll housing and cooling cell technology are what make Raptor significantly different. NO hot engine oil or oil of any type goes to the supercharger, only cool air. Often the SC can be cooler than any other part in engine bay, buy some 20c degrees. All manufacturers quote efficiency ranges, but depends on how SC match motor as to what part of efficiency band you end up using. An SC could be rated at 80% efficiency but due to misapplication (common) it could be running in 65% band. So don't get too hung up on percentages, look at results and if results are good then that product is what you want to use.1298 and rollakid, you are right on with your understanding.Synchron has taken notice of best practice SC system design from Raptor and followed as close as he could, the results say he is doing pretty ok :)And yes it is Raptor V Synchron is using, Raptor R is only for 1000hp and more and not currently in production.</blockquote>
