Dodge 1500 GT-100 - 1977

truly empowered

Corsa Magazine No. 578. June 1977

Dodge 1500GT100

We put it through every conceivable test. After more than five thousand kilometers traveled, its virtues and defects began to appear. Here we take stock and draw our conclusions from this powerful and nervous Dodge GT 100 with 1,800 cm3, 170 real km/h and acceleration worthy of a larger engine.

Write down, analyze and make your personal balance

Chrysler made no secret of its intentions. They were clear, obvious. A manager of the company said it bluntly: "The line of fifteen hundred needed a version with a 1.8 engine that had more nerve, more spirit and also because we have been interested in the highest category of National Tourism for a long time and only now, with this GT 100 we will be able to do it and with possibilities" .

To achieve its goal, Chrysler must manufacture -and certify accordingly- more than a thousand units of this new GT 100 that who knows why it is still called "1500" when in fact it is an 1800 cm3. But in addition to manufacturing them you have to sell them and that has also been thought of by the people at Chrysler.

There's a market. There is a group of people looking for good final speed. Acceleration. Reprise. Agility and maneuverability in the everyday car. For them, or rather to them, this model was directed that contemplates all these virtues.

Dodge 1500GT100

Well-designed manifolds, two Stromberg (SU-type) carburetors, more compression and a cam that pulls up, were some of the modifications that the factory engineers introduced in the 1.8 engine looking for more power to reach the 120 HP SAE that they declare in the presentation brochures.
Outwardly there is nothing new. The painting, of somewhat dubious taste, identifies him on the streets. It is only offered (for now) in black and dark blue trimmed in gold -inspiration or copy of the JPS Lotus?- and with a huge acronym on both sides that read "GT-100". Neither additional headlights, nor spoilers in bad taste, nor excessively wide tires appear as elements to achieve another image of this, the latest product launched by Chrysler.

First impressions

Once seated behind the wheel, the fact that everything there is black stands out. The upholstery of the seats, the carpet, the console that separates the front seats, the interior panels, the visor of the dashboard... everything is black. And therefore, according to our criteria, in good taste.

Dodge 1500 GT-100

The chair is comfortable, it has several adjustment points for both the seat and the backrest and the shape is anatomical. On the other hand, corduroy (or simile corduroy) makes it cozy and prevents your back from perspiring more than it should. The steering wheel is too small in diameter and is placed quite low, meaning that in the case of people over 1.80 meters tall and with long legs, the thighs, in the area close to the knee, will touch the steering wheel. It is also difficult to maneuver to park. The board is very complete. Pointers everywhere and in the case of fuel, oil pressure and alternator, assisted by warning lights. An example for most car factories in the country.

The design is good, easy to read and has a blue-green hue that makes them very visible and pleasant when traveling at night. The rearview mirror is wide and the external one is well placed. The pedalboard is normal, smoothly actuated, although between the accelerator and the brake there is a long distance and it is impossible to tip and heel.
Once underway you can see that the suspension is what we call "stiff". Very nice for the happy ride and turning hard with little roll, but very restless on cobblestones or on uneven roads. The rear axle is dislodged and you have to correct it with the steering wheel and accelerator all the time. He is jumpy and does not copy irregularities well.

When one has gotten the hang of the reactions of the GT 100, the secondary intention is, inevitably, to put the pedal to the metal between changes to check its 120 HP declared. And they appear, there is no doubt. Of course, no one can be sure if they are 120 or 118 HP, but they are there and that is not a story. Below, starting from 2,000 rpm , a certain slowness in climbing is noted, but above 3,500 rpm it begins to push without joke until reaching 6,000 rpm and staying established at 5,600 / 5,700 direct laps, which are 170 real km/h.

It is precisely at that point where most of its virtues are pointed; his engine. Because it works correctly, without trepidation, smoothly, even when traveling at high speeds. The only problem is the "choking" of the carburetors when subjected to a sudden throttle in second or third at low speed. They usually produce an unpleasant cough that leaves you paying in an emergency due to the lack of a spike pump. To normalize this inconvenience, the most logical thing is to always take it in turns, that is, above 3,000, where the engine works with a perfect mixture of air - gasoline.

Heat exchanger

The new Dodge GT-100 has a heat exchanger system between the lubrication circuit and the water circuit. In the Dodge 1500 GT-90, the cooling system of the lubrication system was made through a small oil radiator that was located in the lower part of the water radiator (attached to it). In this new model that concerns us, the solution adopted is considered to be applicable to highly engineered cars. As for example we can say that the Mercedes Benz models are among the few that adopted the heat exchanger system.
The engine lubricant is circulated through a pipe that is inside the lower tank of the radiator, that is, the coolant is in contact with the pipes through which the oil circulates. In this way, when the engine is started up, while it is cold, the hot oil transfers the heat to the water, causing it to acquire the ideal operating temperature more quickly; when, conversely, the water acquires the normal temperature of the engine, it acts as an oil coolant. In this way, the two cooling elements work in unison with the appropriate temperatures for proper engine operation.

Some tid-bits from a FB conversatoon today :

AVENGER AND SUNBEAM RALLY AND RACE CARS
Bill Robertson  ?

I am trying to get my head around the Avenger in Brazil, production from 1971 to 1981 when the Dodge Polara production was stopped when Chrysler pulled out of Brazil.
Some Dodge Polara cars were also sold In Portugal.
The engine was a 1800cc and Des Odell had some blocks brought over and he fitted a longer stroke crankshaft to take it up to 2 ltr, but they were only sold for rallying, but that stopped when the Lotus Sunbeam was launched.
I built my rally car in 1976 and sold it in 1978. I was a friend of Allan Conoly who rallied the first BRM I think in 1978, but never heard of a 1.8 ltr or 2 ltr rally engine.
So if they were around in the UK does anyone have any engine parts, I have a Brazilian head buy now I don?t know if it came off a 1.8 or 2 ltr.
Thoughts anyone

and replies (in no particular order)

Niall Keane
They were taller blocks with a longer stroke. All 1800 to start with were made just shy of 2 litre with 90mm bore.

Richard Troop
I'm same theory as Niall Keane and its info taken from a magazine article titled "avenger brm born under a bad sign"
the increased cc was done by boring to 90mm
1800 was achieved by the longer crank and taller block to compensate for brazils poor quality fuel hence their 1800 only giving same power as our 1600 ....
But then wernt reliable as a 2ltr brm due to longer stroke not liking the high rpm and throwing conrods out
If this was so 🤔🤔
How are the new breed of brm engines not throwing rods ?

Jonathan Charles
Richard Troop the 2.0 BRM engines around competing at the moment are jondel built and are very different including there Brazilians 8v and share little internally to the standard Brazilian and also D.A.D/grp2 that I have.
