i still dont know the difference with the 6-port "not" being able to be extend-ported and need clarity on the because i'm a total retard :-)



would i have to get turbo housings?..or should i just drop a ******* core off at a good shop and say "200hp please"

 

Danno, bridge porting is opening and reshaping the stock port and leaving a small "bridge" for the corner seal to ride across as it crosses over during the rotors cycle. That way you are able to really open the ports up large.



A street port involves opening up and reshaping the stock port. But is mild in comparison to a bridge port.

If i could get my album figured out I could show you the difference.



One gets an engine ported to increase intake flow hence increasing horsepower. Generaly 30% more on a street port I belive.

Ito will smack me around if im wrong on that.

I am not sure what kind of gains you would expect from a bridge port.

Bridge ports are a big difference compared to street ports. So I assume alot more than 30%

 

Bridgeports also tend to let you gain appx 30% more horsepower...and lessen the life of your motor by 30%

 

they really lessen the life of the engine that much ?

why is that exacally?

 

its like a camshaft
