is he running an electric waterpump or what

I'd assume that's what the black cylinder is toward the bottom of the engine bay to the right of the radiator

Thats what i though but is efficient for track only or could it be used for a street driven car

Advantages:
Potential for more flow
No cavitation at high RPM's
Can stay on after the engine is off to cool it down
Can run at the ideal setting for maximum cooling at all times (not dependant on engine speed)

Disadvantages:
Less reliable than a mechanical pump
Puts a lot more strain on the electrical system (high current draw)
More difficult to package and integrate into the cooling system
More expensive

I think that about sums it up. On a street car it's probably not worth it, on a race car for sure it could be worth it, depending on the scenario.

that engine bay is funky. where is the oil filter pedistal? is it blocked off? looks like a dry sump system with a crab/like fuel injector/tb . ide say this is a trakc only car, or a mean *** street car that only runs on weekends or at night.
actually that looks like a drag car. there is no alternator. from what ive seen it runs only from the batery and no alternator. hmm... or it coud be that its not finished being built as there are no spark plug wires nor coils

Front, lower lefthand corner, there's a black cylinder, that'd be the oil filter, plumbed inline with the oil cooler in order to get a bigger filter. But it looks like it returns to the oil filler hole, which is strange.

It's probably a J-Tek (sp?) throttle body and intake setup. A lot of road racers who don't do endurance racing don't run an alternator. The guy I crew for doesn't.

Black91n/a - that's kind of what I thought until I started researching it. Turns out that the latest electric water pumps are unbelievably reliable, and the advantage of having an optimum impeller speed REGARDLESS of engine speed can make a huge difference in cooling effectiveness. Unfortunately, they are still illegal in the class that I run so I can't really experiment with them first hand. As someone who has had an alternator bracket bolt loosen during a race, I can tell you that there are plenty of things that can go wrong with a good old fashioned belt driven waterpump that make them not that reliable themselves. Add to that the fact that slight overtightening destroys them in short order, and they cavitate in sustained high rev use on racecars unless we underdrive them and the electrics are looking pretty damn good!

Looks like a strickly track car to me.

But what is that one belt connected to? Bottom middle of the pic, its yellow and you can see it right above the red FRP.
