Automakers strive to produce the highest-performing engines that meet their budget goals. That often means the performance gains from porting and polishing intake (and exhaust) ports aren't ...

When introduced for the '05 model year, the C6 received the evolutionary Gen IV LS2 powerplant, which carried ratings of 400 horsepower and 400 lb-ft of torque. While the new engine's cylinder heads ...

You understand the importance of getting a good air/fuel charge into thecombustion chamber. It's not just quantity; it's also velocity and ahomogenous air/fuel mixture. To get that, you have invested ...

Since the days of relieving flathead Fords, we've known about the advantage of porting. Grind those critical passages with the right touch, and airflow through the engine improves-and with more air ...

Gasoline engines burn a mixture of fuel and air. In order to create horsepower, your engine must maintain a good quantity and velocity of air/fuel charge into the combustion chamber. Think of the ...

Porting an intake manifold essentially helps increase airflow into the engine. Improved airflow equates to more horsepower and helps the engine feel more responsive at the throttle. A standard intake ...
