Early power plants: These units are available in late tech level 7 or early tech level 8. They are the precursor to the modern plants we have today. They cost 30% less than modern power plants and also put out 20% less power. Weight, spaces, and damage points remain unchanged. They may not use PC’s, SC’s, or ISC’s or any other power plant modifications or accessories. In all other aspects they are the same as TL 8 power plants. Only the following types are available.
 
 
 

Plant	Cost	Weight	Space	DP	Power Factor
Small	$350	500	3	5	640
Medium	$700	700	4	8	1120
Large	$1400	900	5	10	1600
Super	$2100	1,100	6	12	2080

 

Old gas engines: Gas engines have been around for nearly 200 years, yet most duelists have never seen one outside of the arena. This has led many to believe that these engines are only the prerogative of the rich, but if anything the opposite is true. Often it’s the poorest people living out in the wasteland who make extensive use of gas engines. Hoards of these engines still reside in abandon junkyards left over from the 20^th century. Using a variety of mechanical techniques and fuel types the scavengers of these treasure troves have managed to put together impressive fleets of battle ready machines.

All gas engines have the same weight and damage points, and take up the same number of spaces as TL 8 engines. If not mentioned here all other rules are as for TL 8 engines. Gas engines may be swapped in and out of vehicle bodies of different tech levels at 10% over the base cost of the engine being put in.

In my campaigns overdrive and heavy duty transmissions are available for all gas engines at regular cost.

Tech level 7 engines: Almost all of these are fuel injected though all gas engine options are available at regular price. Gas mileage is the same as for TL 8 engines. However cost is 30% less and power factors are 20% less than TL 8.

Tech level 6 engines: Most of the smaller engines (200 ci or less) are fuel injected while the larger ones tend to be carburetor fed. All gas engine options are available at regular price. Gas mileage is 10% worse than TL 8 engines. Cost is 45% less and power factors are 30% less than TL 8.

Tech level 5 engines: All of these engines tend to be carburetor fed. Fuel injection is available, but it is uncommon. The same goes for super chargers, turbo chargers, and blue printing. Variable pitch turbo chargers are not available. . Gas mileage is 20% worse than TL 8 engines. Cost is 60% less and power factors are 40% less than TL 8.

Fire and explosion: Gas engines of TL 7 or less have the same chance as TL 8 engines when determining fires and explosions.

Gas tanks: At tech level 7 racing, heavy duty, and economy tanks are available. At TL 5 and 6 only heavy duty and economy tanks are available.

Damage: Despite what tri-video programs show, old gas engines are even more susceptible to damage than TL 8 engines. They lack the compartmentalization and redundant systems of today’s combat machines. To better represent the fragile nature of these older machines I have changed the "Gas engine critical damage table". The roll for the table remains the same, but the chance of permanent critical damage is increased.
 
 

2 or less – Minor damage, reroll on this table once per day until fixed by a mechanic. This is an easy job for a mechanic to repair if caught in time.

3 – Major damage, reroll once every hour the engine remains running. This is an easy job for a mechanic to repair if caught in time.

4 – Electronics are hit. The battery was blown away and fuses shorted out or the alternator or spark control box was damaged. The vehicle must decelerate by five miles an hour per turn and may not accelerate, also any devices that require power to run (including computers) will not work unless the vehicle has a laser battery or its equivalent. Repair is an easy job for a mechanic.

5 – Brakes are damaged. A line has been cut or the master brake cylinder hit. Deceleration greater than 5 mile per hour is an extra negative two hazard. If this result is received a second time the brakes are gone and the car can only decelerate by five miles per hour until fixed. Repair is a medium job for a mechanic.

6 – Steering is affected. The power steering pump is gone or the column damaged. All maneuvers are now at an extra negative two. If this result is received again the steering is gone. The vehicle can only continue in the direction it was heading before receiving this result. The vehicle may accelerate and brake normally, but may not perform any other maneuver. Repair is a medium job for a mechanic.

7 – Compression is lost. Valves were bent, rings damaged, etc… Halve the vehicles acceleration rounding to the nearest 5 mph (once 5 mph acceleration or less is reached acceleration drops to 0 on the next compression hit), and subtract 20% from top speed every time this result occurs. Repairs are a hard job for a mechanic.

8 – Transmission, as per regular table.

9 – Radiator, as per regular table.

10 – Oil system, as per regular table.

11 – Fuel system, as per regular table.

12 – Disaster, as per regular table.

13 or higher – Fire, as per regular table.
