Alfa Romeo Alfetta GT

Giugiaro’s original sketches for the Alfetta GT prototype

Thanks to my friend Kenny, I have an Alfetta Sprint Veloce.

Thanks to my friend Steve Fields, purveyor of automobilia, I now have the book, Alfa Romeo Alfetta GT by David Owen. Owen is the author of numerous Alfa Romeo books.

Alfa Romeo Alfetta GT covers some of the history of Alfa Romeo, the Alfetta’s family tree, Alfa Romeo racing and the Alfetta GT through the GTV6.

The Alfetta GT chapter outlines the design ideas and engineering solutions to problems such as weight distribution and rear axle design. The result being a clutch-transmission-final drive unit, DeDion rear axle and in-board disc brakes.

I’ve read that Giorgetto Giugiaro‘s original design for the Alfetta GT had retractable headlights, but I’d never seen any images. Owen’s book illustrates that with some of Giugiaro’s original sketches.

For the illiterate crowd, there are eight pages of color photographs plus black and white photographs of Alfettas and its predecessors throughout the book.

Alfetta Cooling Fan

Flex-a-lite model 390 10-inch S-Blade reversible electric fan

I think because my 1979 Alfetta Sprint Veloce has an air conditioner, engine cooling seems marginal when the ambient temperature is above 80 F (27 C).
When running at speed, the temp gauge indicates a normal 175 F. But when stuck in traffic, though the engine doesn’t overheat, the gauge goes halfway between 175 F and 250 F (79 C to 121 C).

I had the radiator checked at a radiator shop; they said there’s nothing wrong with it. I’ve bled the cooling system at the pump and thermostat and use Red Line Water Wetter in the coolant.

In an effort to help with cooling when the car isn’t moving, I replaced the stock electric fan with a new one. My reasoning was that a fan with a modern design might be more efficient. I bought a Flex-a-lite 390 S-Blade Black 10″ Electric Fan. It’s a 10″ fan that advertises 775 CFM. The space behind the radiator doesn’t allow dual fans or a larger fan. The new fan doesn’t seem to make an difference in cooling.

I also thought about using the new fan to replace the one in front of the A/C condenser but I wasn’t sure I’d be able to remove the old fan without removing the radiator and A/C condensor. I know the old fan won’t come out through the gills below the bumper. I haven’t removed the grills yet. I cleaned a few bugs off the condenser, but even when the A/C fan is on, I can’t feel much air coming through if I put my hand behind the radiator.

Fiamm Horns

Fiamm 3 Trumpet Riviera Horns

For some reason, I wanted Fiamm horns. It has something to do with owning an Italian car, seeing all those movies shot on the Cote d’Azur and Rome, and for some reason, associating Fiamm with Italia. Maybe it comes from my Fellini period.

I bought Fiamm 3 Trumpet Riviera Horns. The triple horns are powered by a 12V+ air compressor. Connectors, tubing and a relay are included in the kit.

On my Alfa Romeo Alfetta Sprint Veloce, I mounted the 3 horns on the inside of the front section of the wheel well, behind the right side headlights.

To mount the compressor, I used the existing bracket that had one of the OEM horns mounted to it. I had to ream out the hole and bend the bracket 90 degrees. For power, I used the existing 12v+ for the horn and added a ground wire. There is a slight delay while the compressor spools up when I press the horn button.

What it sounds like.

Ferrari Building a Smaller, Lighter, Quicker Enzo

kianet over at Digg writes about a Wired story: “The go-fast gurus at Ferrari are working on a successor to the jaw-dropping Enzo that could be the lightest, quickest two-seater ever to roll out of Maranello.Ferrari sees lighter cars as the best way to reach its goal of increasing fuel economy 40 percent and reducing emissions 25 percent without compromising its reputation for performance.

My Alfetta’s curb weight is around 2700 lbs (1227 kg) and has about 110 hp (82 kW). I wonder what a 2200 lb (1000 kg) car that has 600 hp (447 kW) would be like.
