Wow Todd!
Beautiful porting indeed! I remember you talking about some of the porting that you've done on cylinder heads and it's clear that you have put some time behind the grinder!
Ya the flash in the housing is horrible. Similar to what you have going on in your photos. I see a lot of promising spots to hit, but I'm unsure about the impeller entry. What are your thoughts about laying back the hard corner where the water is introduced into the impeller? It seems important to keep a close tolerance between the impeller and housing. Speaking of close tolerance, it is clear that an impeller touched the housing at some point in its life. The aftermarket pump doesn't have any interference when dry fit, even without the gasket.
I'm excited to break the die grinder out again this weekend. And a started another small surprise that I should be able to post tomorrow.
Thank you!
