yeah its neat, brap brap brap. how do you thnk it would run if you did the streetport part of that and just didnt cut the bridge?

Mike, I think it would increase over 35% of power when the auxilary bridgeport opens with the 5&6 port activation. Meanwhile keep the regular 850rpm almost stock idle. This would work but the sleeves need to be inserted back into the engine to keep the 5&6 bridgeport closed at idle.

Hey Ito, if you were to do the bridges on just eh aux and secondary ports could you block them off and make a different fuel map to get through DEQ, or is that just a stupid idea?

Run this by me again. and what is DEQ? I'm from the east coast I think we don't have DEQ

I lived in L.A. and Bay Area so I know what he means. they put a tail pipe emmissions reader in the exhaust which tells the shop PC and state if you pass smog limits.

Its tuff , kinda like the Dyno setup but tells you levels of Carb. monox. and others.



I guess if he could run lean or put an additive to burn it just for the test.



But its easier to "find" someone who will help out @ the station.We are like Jersey,

we dont need no stinking smog device...

we got alligators to worry about.

Well My Idea was to run a bridge like you have there just on the secondaries and aux ports. And do a mild street port on the center plate. So that way when I take my car to a smog test (like described above) I could make a small plate that would block off the secondaries and aux ports, and just run the engine off the primary ports, this way I wouldn't have all that overlap.

I am just kicking around idea's at this point.
