junk BRASS

[blaster800]

During my eng build I removed the 2 brass fittings on the bottom of the B-pipe manifold and found this . I never thought of this Chinesse trick to save money !! the threaded end is drilled less than 1/4'' @ .200 inch and the barb end was .280 the elbow has way lesss brass so I compared to some other ones I had note: the FAT elbow drilled .280 at both ends just food for thought when buying brass , less chance to snag a pebble or zebra mussle shell

Interesting. We all talk about the size and amount of cooling lines but seldom do we really analyze all the little points in the middle. One restriction is enough to affect the whole system.

Factory Pipe furnished "drilled out" fittings 20 years ago and it was recommended for better water flow. If you drill them yourself, leave enough wall thickness for strength.

I'm surprised you don't see anyone with an inline guage to monitor water pressure on their cooling systems.

I used to drill mine out. But now I find my self trying to restrict water to keep pipe and cylinders at ideal temps.

I guess what made me look was I remember about 4 years ago FROSTY lost a motor due to a perfectly round pebble getting stuck in the 90 degree fitting, that indicates the fittings are one the most likely places to get an obstruction . the bottom of the manifold is the last place i want to be working on the beach so for me thats not the best place for the smallest port in your cooling system IMO , so ill just HOG em out a little and hope it helps . Ill keep my restrictions at the pissers

The cooling system should be laid out just like the intake to the pump, if it fits through the opening, it will pass through the entire system.
