Carburetor Tuning: A/F Mixture, Air/Fuel Equation
Now that the ignition spark timing advance curves are optimized for the blend of reformulated and/or oxygenated gasoline your customers are using we will now show you how we use tools such as a 5-gas exhaust analyzer and wideband Lambda air/fuel (A/F) meter to tune the mixture. The Air/Fuel Mixture A lean fuel mixture can
Connecting Rod Stress
Connecting rods are subject to constant stress through extreme tensile and compressive loads, each one tied to a different aspect of operation.
The Importance of a Good Valve Job
The valve job ensures the mating surfaces of the valves and the seats properly control the air/fuel mixture.

EFI Timing Control & its Advantages
No one can overstate the fact that EFI timing control has radically changed the ability for anyone to fully, and correctly, optimize an ignition timing curve, assuming they are interested in investing the time.
Tech Line’s Polyphen Piston Top Gold Thermal Barrier
This thermal barrier requires oven curing at 300°F for 1 hour and is for professional applications.
Nitrous Update
The use of nitrous oxide in diesel engines is not a new concept. In fact, it has been used in drag racing for decades. However, it is only in recent years that it has gained widespread popularity in the worlds of diesel truck pulling and drag racing. Now, it seems as if almost everyone in the competitive scene is using it.
Diesel Piston Technology
Diesel and heavy duty go hand-in-hand. There’s no way around it. High compression causes high cylinder temperatures, with peak cylinder pressure often as high as 2,700 psi (or higher). This high pressure and high heat only have one thing in mind, to beat relentlessly on the first thing to get in the way – the pistons.
The Engine Cummins Never Built: A Look at the 6.4L Cummins
With increased technology in turbo systems as well as fuel systems, the final limits of the 6.4L Cummins have not yet been discovered. These engines are capable of being a competitor in any event, whether it be truck pulling, drag racing, or cruising the strip.
Speed Density vs Alpha-N Tuning Strategies
Choosing the best strategy for your application will ensure that the correct fueling and spark event is applied to the engine.
EFI Sensors and Uses
EFI systems can employ numerous sensors to perform many tasks, including data acquisition, but this article will concentrate on only the required sensors.
LS Cylinder Heads
The LS engine is known for its cylinder heads, and there are tons of options available to upgrade the factory components.
Open Loop/Closed Loop and Learning
Closed-loop control can be programmed to either add or subtract up to a certain percentage of fuel in order for the engine to reach the target air/fuel ratio.
Going the Extra Mile with Cylinder Head Porting
It’s not just the port work alone that creates spectacular cylinder head performance. The most critical areas of a cylinder head are those which pass the most air at the highest speed and for the longest duration. Your bowl area, the valve job, the throat diameter, and combustion chamber are all crucial parts.
Nitrous Supply Nitrous Charging Kit
Mike Thermos and his team at Nitrous Supply have been working with leading forced induction racers to improve performance through adding a shot of nitrous into the intake tract. This increases performance and eliminates turbo “lag.” It’s ideal for both drag racing and drifting. The injection of N2O does three things. First, it significantly cools
