wonderful engine Nick , love the whine up to speed, I wish we could create that sound all the time , but unfortunately it takes throttle up & down to make er' sing like that , I have always wanted one of those 95's , very nice plant for sure.
It really sings when it's not belted up, unfortunately the gears have a bit of chatter which kind of ruins the whine. Sure is a pretty engine though
Not much you can do about the gear noise. I tried different oils to quiet them and all I got was very brief results and a mess to clean up.
I’ll have to run my 95s again and see how my throttle valves are. I don’t recall them leaking like yours does. A little lapping should fix you up though. They do make a fantastic whine when spooling up!
