I know of a guy with a temp sender in his rear end...but I don't recall if he has a fluid cooler on it or not.

I guess technology has come a long way since the rectal thermometers.

I didn't see the manufacturer on the pump. They are a low volume and only 6 amp. They are switched with a dash toggle that says "Aux Pumps". The switch also runs the tranny cooler

I see two (actually three) things wrong with this installation, the ring gear is on the other side of the inlet (cooled fluid is not spraying on the ring gear as it should), the hose end on the bottom of the diff is far too low and could get ripped off in an "off track" excursion, and finally no screen filter?? blow a rear end and you have metal in your cooler.

PS: thats not a Tilton pump...

What red said. I have one, just waiting for the screen filter which is lying at a buddies place in the US waiting to be shipped.

The pickup picks up from the rear, where ring gear rotation and inertia push the oil. The return sprays the oil onto the ring gear. There's an even better way by spraying directly in the contact area between ring gear and pinion but this is easier to hook up. Still need to hook up the cooling air hoses to the ducting. BTW, this IS a tilton pump. Hoses are sized -8.

I never said that this was one of our shop cars. This was just for general cooler idea info. I should have said "kind of how we install them.

Anyway Red this is Vic Edelbrocks vintage 63 race car cooler setup. Good job hu!


Red, this weekend is the Infineon Race way historics. I've been working till 8 at night getting the Lola/Ford T-286 ready to go. Look for #11 to win again. The other guys are race prepping the GT-40 and a lola t-70

Might I add that switching a pump off the dash is foolish if you can simply have it switched thermostatically? Another thing the driver won't have to worry about.

Generally there are two kinds of "racers" at the race track, racers and posers...the Edelbrocks are definitely posers, they are there to drive around and look special. I can`t remember his name but I believe they have a guy working on their stuff full time.....

Christine Edelbrock is a good driver. Yes Earl might stage the out come and every top placing car is cheating. But the top cars are going for the gusto. I took a few videos from this years three races at Laguna.

She was over for coffee every morning because our transports were near each other.

We actually have three great drivers that win in the top classes of Ferrari challenge, Can-am, & 2-3 liter in the lolas and chevrons.

Then we also have the no problem crashers

Did you notice that car uses the small diameter halfshafts and non hd yokes (using straps, not caps). Looks like the u joints are 1330s even. You might be on to something with that poser statement That ancient looking pump is a facet interruptor pump by the way. It's not even an oil pump, it's an old style fuel pump.

V-twin. This weak half shaft 63 Vette is a period correct 327 ci that probably makes @ 400 hp on the dyno with stamped steel rockers. They are also raced prep before each event. So it is not like they get many miles between total check ups.

Lot's of things on pure race cars look very small and flimsy. It is to save weight. Only if a part fails is when it gets improved.

Save weight, yet they have what looks like a 50 lbs contraption to hold a simple oil coolver and pump. Just one look at that pic and I see tons of places where they can shed weight. I have seen quite a bit of all out race cars and that doesn't even come close to what is done to eliminate excess weight. I fail to see how a set of HD yokes will weigh considerably more than a set of what you see above. The only difference is, that if you break one you're out of the race. Hell, even the BB street cars came with the heavy duyty stuff. One look in a Chevrolet Power manual and you will see all the heavy duty parts available and recommended for these race cars.

On my picture the half shaft has a name Wenco I found their web site it might be a quality piece.

I did a 63 Z06 differential that used the fill plug hole and a tapped 1/2 npt hole above it for cooling. Never saw how it was plumbed, just had the diff to rebuild.

We have 4 chevy 327 powered vehicles in our shop. They are all 4.060 bores and 3.250 stroke for 336 ci. They all have similar "Legal" iron heads. solid lifter cams of different sizes and a variety of intakes from 650 4 barrel Holley to 4 weber side drafts.

I've run all of them on the dyno. Three of them make right at 400-410 hp @6200-6300 rpm and everyone one of them has stamped rockers. The bizzarini and the four webers is closer to 450 hp

Red, why would I think that Vic would not be using the same legal parts as our cars?
