Sorry for the late response, upping the injection rate still does not get oil to the middle of the Apex Seal.
Pre-Mix is the only and easiest way, unless you use S2 Rotor Housings, etc, etc, etc.
How is the project coming along?
I checked with Pip (WGT) on this issue. He has now rebuilt the engine and said there was no extra wear at the middle of the Apex seal, the original seals had worn down evenly. They were replaced anyway and the engine cleaned up. With that info, I\'m happy with direct injection at a higher rate. A washer bottle will be used for this oil with a fill-level warning so I can top up when it runs low without having to check the oil on every fill up.
All the mechanical parts are done, ducting for oil coolers and undertray is done, ECU is being wired up and final fit is happening right now with tuning/debugging due over the next two weeks. One little problem is finding a tach gauge that goes above 9000rpm.
