Tweaking It Up
I wanted to bleed air from the top of the water pump and upper radiator tank.
I used -4 Aeroquip lines and whittled this aluminum adapter to go into one of
the low pressure heater hoses.
The radiator had a 1-1/2" lower outlet, the water pump was 1-3/4. My welded
tubing hose adapter leaked, so instead of simply epoxying the holes up or
something reasonable, I carved this billet aluminum adapter on the lathe. 1/8
NPT ports are for drain petcock and radiator-return water temp sender.
Looking down from top, passenger's side, at lower front crossmember, from the
front. All the removeable sheet metal is off; front of car is to the right.
My second-try radiator brackets were cut from 1x2 rectangular tubing, as you
can see on the right. Red steel bracket on left is one of the electric fan
brackets. Note wrinkles and braze from previous total collisions (3).
The new airbox setup and taller, 3-core Maverick radiator required trimming
some of the bracing from under the hood. Didn't seem to hurt anything.
Day before the second track event. New radiator cured overheating problem.
Airbox is 1x4 sides and 1/8" veneer, coated with epoxy. I was going to make
one out of aluminum or fiberglass later, but the wood one is still in perfect
shape after three years. Conical air filter is from a Swift DB2000 race car.
Cutout ahead of radiator is from when I had the electric fan attached to the
radiator instead of the body.
