What is semi p port?
A semi-peripheral port, in which street-ported side housing intakes are used at lower rpm and smaller peripheral ports are used at higher rpm, is another option. So there you have it, rotary porting in all its flavors—from the mildest of street ports to the wildest of peripheral ports.
What is a semi p port 13B?
Once one of our dealers was tuning what’s commonly called a semi peripheral 13B engine. For those not familiar with this porting arrangement, this is a standard 13B 2-rotor engine, where the two side intake ports are retained, but an additional peripheral intake port is added. So each rotor has 3 intake ports.
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.
What is street porting a rotary engine?
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.

What is the difference between street port and bridge port?
Bridgeporting is similar to streetporting in that like streetporting, the intake ports are extended, but now a slit is cut next to the port which opens up the port sooner then before, while still allowing the corners seal to cross over a bridge of metal.

How can I make my rotary engine faster?
Can You Boost A Rotary Engine? Using the 900 HP, 3-rotor engine for optimizing the oil pressure or a Supercharging/Turbo recommendation is to increase it to a pressure of approximately 80-90psi or higher or 120 psi or higher. Use lower compression rotors if you intend to boost levels above 5 psi.
