It's Labatt's 240260280.

 

[wheee!]

Probably Keiths IPA.... but I like your subtle humour cap'n!

If you subscribe to engineering magazines like Racecar Engineering and  Race Engine Tech, they often have articles on Cooling system design. Circle Track Racing also has very good articles.  The testing has already been done. You just have to find the articles.

BTW... the stamped steel designs always fall to the bottom of the tests. It's not a real surprise is it?  Look how complex Compressor wheels are on a Turbo. W/Pumps are the exact same thing. Only thye move a Liquid, not air. Same principles apply though. 

W/Pump design gets very, very critical. It is surprising how the smallest detail can affect pump efficiency.  All of your Top Racing w/pimps use CNC designed impellers and Volutes these days.  Equal flow, block pressure and Anti Cavitation are all areas that must be addressed. Impellor to Volute clearances are very critical. The lack of the back plate of those Stamped " Paddle wheels " greatly affects their efficiency.

Cider pumps best in my neck of the woods.

Stayed out for about an hour.  It hit the right leg of the "M" like usual and never moved.  Fixed the leak though so very happy.  So much I'm about to give it a bath, maybe the dog too.  It's 65 degrees and sunny. 8^)

I'll get another gasket on the cast impeller pump, clean it up and put it back on in a year or two.  Getting the four lock washers and nuts on the fan clutch isn't something I enjoy, actually I hate something so simple to be so tough.

Did you check the "weep" hole?  That's where the shaft seal leakage comes out on the water pumps.

I bought some stainless bolts that were an 1/8" too long.  Never had a good seal until I put the Nissans back.  Happened on the oil pump too.  OE bolts, no drips no more.

SS bolt too long?  Call on

Maybe before Zcon '18 I'll have shiny headed SS bolts but for me this an OCD lesson, compromise function over form. 8^)

I've PM'd a couple of guys that will run into this minor mistake.  Maybe they'll read this and see your Mr Grinder video? 8^)

The Grinder app has ruined that word for me.  No longer in my vocabulary.  Thanks pervs!
