    Dimpled aeroport partsexpress

    Has anyone tried the new dimpled 4 inch port from partsexpress. Has golfball like dimples to increase airflow I just ordered one I assume it works better or else they would have not made them I will try it in my bandpass which has the regular 4 inch to see if makes any difference on portnoise or tuning etc. Precision Port Dimpled 4" Flared Port Tube Kit 268-353

    I am not expecting any difference but with golfballs the dimples can make a lot of difference and i guess theoretically if not done right it could add resistance. Maybe I will get more distance off of the tee with these.

    I have the regular flared Precision port and doubt those will make much of difference.

    I would imagine that the ave guy isnt going to hear any difference on daily listening. It might help somebody who has a port was too small and making noise to start with. I guess the biggest help would be to the guy that is in the lane trying to get a higher score, this might give a slight edge.

    Will do I do not have a db meter but the 4 inch aero I have now has some port noise when it is cranking so I will see if there is any reduction in port noise.

    Re: Dimpled aeroport partsexpress

    We have swapped them in a few enclosures here and didn't hear a difference, but we didn't meter the cars so no idea on the meter. If he comes by again I will try and remember to check it out. I don't think there will be much if any difference though.

    In theory dimples in the port and flare area should disrupt the airflow you normally want the port to be as smooth and free flowing as possible.

    That was my view on them as well. I just don't see how this can help really.

    I have tested the original areo port against psp and in 99% of our tests there was no or next no difference(meaning less then .1db)

    what are you guys talking about when you're saying the original aero port....I thought psp was the only one around, but I haven't been in the game for that long either
