Is this a good combination?
How is driveability and engine life affected (s4-13BT)
More HP then a streetport?

I don't care about fuel economy or a LITTLE driveability problems but this will be my daily driver and i want it to pass smog tests (live in sweden thou)

tell me everything there is to know about this combination...info, movies "gossip" etc!

 

Yes.

Driveability is worse at lower throttles (surging), but engine life should be unaffected if the ports are cut correctly as to not intrude on the side seals.

Yes, much.

Good luck! You would need some seriously lax tests to pass due to the large amount of overlap generated by a bridge.

 

I have one....peak power doesnt seem much more, but good lord did it spool my 60-1 fast.

 

I have a theory about passing smog with a half bridgeport.

Aux port sleeves are used to have the aux ports closed at low rpms, so in a sense they are blocked off yes? Well, why cant you make something that blocks off the secondary ports completely for half bridge people for when emissions comes? Either a plate or something, whatever works, and run off the primaries only to and from the test. No more bridgeport to worry about! Obviously power is going to SUCK and you're going to have to retune for those rpms to just get there and not have way too much fuel during the test, but in theory it should work.

 

If I had to worry about emissions I guess I would try it.
