Hey guys i'm building my n/a engine with a bp onthe aux. port do you guys have any idea how this is going to react when aux. port opens up is it going to feel rough or is it going to feel normal?All the mods were done to the engine the rest is stock.Istill have not put the engine together, any suggestions would be greatly appreciated.

Don't use a stock ECU/FI computer, and I would stay away from the stock intake manifolds.
Mazdaspeed7 did this and said he wasn't too pleased with all the limitations stock equipment gave him.

That's probably a good idea. The porting itself is a great way to keep low end and then have good power up top... the problem is trying to use the stock stuff with it. It maxes everything out, and the port timing is all wrong for the length of the intake runners. You need to separate the aux port runner from the other ones, it needs to be much longer.
Good luck

Dear god...I hate to sound like RX7club, but those FAQ's are there for a reason. I have gone very in-depth on my aux bridge experiment, and really dont feel like typing it again. Search my username and "aux bridge" and you should come up with 2 threads in thie forum(or the FAQ's) that have all of my results/thoughts on it.

Maybe i should use the stock sleeve in the port until i can upgrade the ecu and change the manifolds.that way the bp won't be activated when open.
Im much happier with my SP engine than I ever was with the Aux bridge.

I hate to sound like a dick, but maybe you should take care the manifold and ECU first. The stock sleeve will only close about half of the eyebrow. You will have an engine that barely runs on the stock ecu, and youll hate it. The S4 AFM has a lot more range than the S5 ones, but you will still never make good power with it, but more importantly, you will lose TONS of low end and midrange.
