The pulley....
This thing took a while to get.
It's a custom pulley I had made so that I could use the Steward STE50025 Pro water pump. The pump is standard rotation vs the factory reverse rotation pumps.
This pump is one of the reasons I flipped the intake backwards. Because the water pump feeds from the top and the throttle body would be in the way.
Now all I'll have on the front of the engine is the water pump, alternator, and crank pulley.
The belt will be tightened by and adjustable alternator bracket.
No idler pulleys, no power steering pump. Nice and simple.
It's now off to get black anodized....

I put a lot of thought into that. But as I Googled the various LSx forums for people that used the Meziere (or any other electric water pump) for racing... all I found were mixed results. All sorts of various issues.
Nobody I could find said that they used it for real road racing and had no problems.
And no professional race teams use them either (none that I could find).
I do know that the Steward water pumps are used on the Grand American Prototypes on the CRD engines in the Rolex 24 (which was on a prototype that won btw...). And they are also used a ton in circle track racing on the classes that run the LSx engines.
And I'm concerned that none of the electrics really flow enough water either. The race Meziere claims it puts out 55gpm. The Stewart race pump I'm using claims it puts out 140gpm. Big difference.
Do you need that much water flow? I have no idea. But I'm sure Steward wouldn't design their purpose built race water pump to flow that much for no reason.
Lastly... it just feels odd depending on an electrical circuit to cool the engine down. If the pump fails, there's no control circuit on it. If you don't see your temps going up real fast... you've got a big problem. And when I'm racing, I really don't have much time to look at gauges lap after lap.
So... just not enough there for me to take the plunge or assume the risk. I went tried-n-true and simplified a the front drive layout in the process.

Hard oil line fabrication and cutting the water pump down to the final height based on the new pulley....
(It's the small stuff that seems to take forever....)

What are those two large metal trays for?

Irony: a leading part of humor... using words to express something completely different from the literal meaning. Usually, someone says the opposite of what they mean and the listener is left to ponder the exact meaning.
Hyperbole: extreme exaggeration.
translation;
1. implicit; build quality almost beyond belief/stunning attention to detail/superlative photos (understated).
2. as always, i enjoy bumping (on the no fun forum) in an attempt to pay a subtle compliment

Thanks for the tip. Irony is best used in conjunction with a semblance of relevance. Not something we tend to find common in your posts. They tend to be obscure and obtuse just for the sake of it...
