What does porting a rotary do?
Porting Basics At its most basic level, porting the intake and exhaust ports on a rotary engine is the same as porting the cylinder head(s) on a piston engine, in that the objective is to improve airflow in and out of the combustion chambers.

Can you port a rx8?
Street Port Entry level porting and one of the most widely used. This type of porting is ideal for the road-going daily-driver, be it for your RX-7 or RX-8, the Street Port will offer an increase in horsepower at the high end and a little more torque in the mid range on naturally-aspirated and forced-induction engines.
What is a peripheral port rotary?
Peripheral Porting: This is the most extreme type of porting for your rotary engine. Peripheral porting involves completely sealing the side intake ports on the engine irons and creating a very large port on the rotor housing itself. We definitely do not recommend this for any kind of street use.

What are the different ways of porting a Mazda rotary engine?
If you’re a fan of Mazda’s amazing rotary engines, then you’ve no doubt heard terms like ‘street porting’, ‘bridge porting’ and ‘peripheral porting’ being thrown around, but it can be confusing trying to make sense of the many ways in which these engines can be ported and how each method affects engine performance.
How do you increase the power of a rotary engine?
Aside from adding a turbo or supercharger to a rotary engine, the only other way to increase performance is by porting the intake section of the engine. Porting a rotary engine is a way to extract more power from it, although often, the bigger the port the less drivable and practical the engine is.
What are the different types of Engine Porting?
There are several different types of porting available for the rotary engine, ranging from mild all the way to the peripheral port. A turbo rotary engine can also receive a porting along the lines of a mild or extend port, bridge-porting a turbo motor is possible, but it is uncommon (due to overlap).
