Not so far, but like I was saying you can see that it would be easy to not get it sealed on the dyno.
So I’d need to strip the headers, drain the oil, pull the engine off the dyno, stick it on a stand, remove the pan, install the scraper, seal all that up and stick it back on the pump.
Oh yeah, I’d need to remove the drive plate and flywheel to get it on the engine stand.
I’ll think about testing it with and without the scraper but I’m at best 50/50 either way.
No need to torture yourself. I'm confident that the way to go. When you look at the I-H webpage, the FE windage tray looks like the perforated tray I made for my 340. Jenkins seemed to be proud of the gains he was getting out of reduced windage.
