s4 half bridge port s5 intake

ok my car has a s5 intake but while it is out i wanted to bolt on my s5 intake i got (it should flow better right)
my question is should i try to hook up the vdi or leave it open
i was wondering if it will do any good since i can not run the aux port seleves becuase of the bridge port.


thanks

s4 or s5 wont flow any better in this particular aplication.The NA intakes were not designed 2 deal with this type of porting,in the end you are gonna loose power instead of gaining some.I seen some NA halfbrides running T2 intakes and they seem 2 run better.Are you running a stock ECU.

Either N/A Intake will be criminal on your application. Its going to rob you of a lot of power.

Can you post some pics of your ports?

Since you are making a 6 port bridge, your goal must be high RPM power. Get a manifold designed to mount a Weber side draft to your block (Mazdatrix) and a set of ITBs (TweakIT). Build a nice airbox with a cold air intake.

i will seen if my engine build has any pictures of the ports but the port deign is a streetable bridge port he told me it is an extended port (large street port) with eyebrows (bridge) with mild over lap

but still large enough to have the aux port seleves block the bridge port opening

so judgeing form the replys the intake i have is going to choke the engine at high rpm correct
