Anyone have an electric water pump on their BBC and run an alt? If so what brackets are you using and where is it positioned at?

I run a Meziere electric pump and use an East Coast Auto Electric alternator bracket that puts the alt very low on the passenger side. Also had to buy a 45 degree inlet adapter fitting for the pump so the inlet hose would clear the alt bracket. Had to grind on the bracket to clear the harmonic balancer.

I'm using a CSI waterpump and this bracket setup from GZ motorsports to put the alternator on the drivers side. This is a crank mandrel setup, it wouldn't work the same on a conventional pulley setup. Since this is on a Nova where the crossmember is very close to the motor I can't go much lower. On a Chevelle you could mount the alternator much lower and use a conventional style crank pulley I believe. Jones racing makes some real nice ones http://www.jonesracingproducts.com and so does Alan Grove http://www.alangrovecomponents.com

505,
whats that little brass thingy next to the breather on the valve cover? :confused:

That's the fitting for the vacuum gauge line.

Thanks guys... I will have to print off the Alan Grove stuff and see how it looks. It says they bolt to the water pump in a way which it will work with an electric. My current alum edelbrock pump has holes for the stock mount and I am assuming from looking at the various electrics availble the stock bracket isn't gonna work.

505Nova... nice looking beast under your hood there. I like it. What does she run and how big of shot?

What kind of vacuum do you see in the CC? I cant imagine that you get anything with that vent there right next to it do you?

Bob

I was gonna ask the same thing!
Nice engine bro graemlins/beers.gif

Hehehe - gotta give you guys credit, I've had that valve cover breather on there for several months and nobody has caught that till now. There is actually a vacuum relief valve underneath that filter. I just didn't like the idea of sucking in any dirty air into the crank when it opened.

Haven't ran the nitrous yet, tore the transmission up in it last time out and getting that fixed now. Next spring we'll be starting out with about a 200 shot or so. Runs 10.62@133 now with a slipping 2nd gear in the tranny.

Ahhhhhhhhhhhhhhhh, Very crafty. how much vacuum are you running normally?

have you seen any vacuum fluttering on the motor? in detonation maybe?

Bob

The relief valve is set to pull around 12" in the traps. Pulls about 5" at idle. As far a fluttering goes, I have no idea, never noticed that at part throttle at least. I don't have time to look at it when making a run, about the best I can do is take a quick glance at the gauge.

"someone in the know" tells me that when you are making laps & you watch your VAC gauge on your CC you can tell when the rings are fluttering due to detonation (too much bottle/timing;)).

The hard part is as you mentioned watching the Vac gauge & keeping the car from bouncing off of the rail @ 130 MPH. this is where a data logger comes in VERY nice.
