    Supercharger Porting

    Guest-only advertisement. Register or Log In now!
    So i was reading alot about this in the B8 section but wanted to see if anyone has done it to our platform. Kind of interested since it does't require much of a tune but you have to source a supercharger housing. The gains are pretty significant so want to get a feel for it if anyone has done it here.

    I question this porting thing - if you get better gains all around then why wouldn't the manufacturer doing it from the start?

    They would use less metal as well

    I concur.
    You may very well increase air flow at some speeds to the detriment of others.
    If I can't fix it I can fix it so nobody can fix it.

    I have not looked, but I wonder if any of the B8 guys who have done it have posted actual before and after dynos of this, and not just reporting back butt-dyno impressions :) . That would certainly answer your question

    I don't even know if I trust dynos anymore - I swear to god I see a delta of 100whp on cars with the same mods... I've seen cars do +- 20WHP on sequential runs...

    The only thing that's objective to me is a 1/4 mile and trap speed but that also takes into account track conditions + driver

    Someone posted their dyno and saw an increase of 11whp and 14wtq. Someone else posted numbers paired w/ a highflow cat an increase of ~25whp and ~40wtq. Of course dynos vairy from car to car and location to location. Also people with them log their cars and see a hefty increase in boost.

    Dynos always change from car to car and location by location, and not all cars respond to mods the same as others due to various vairables. When I dyno'd my previous car after every pull the numbers would rise. My tech said after it usually takes 4 or 5 pulls on the dyno to get an accurate reading. What we can take from dyno results is what can be expected.

    But looking at the gains by this $700 mod seems interesting and thats why i reached out. Not many manufacturers like to R&D for our platform so seeing something that can squeeze power from our motor is always a plus.

    If you can find quantitative gains I'll do it

    Can you explain your theory as to why it doesn't come like this stock?

    I can understand a detuned car, but a less efficient super charger makes no sense

    the manufacturer is not looking to make the highest HP number out there...that is why so many mods like tunes, smaller pulleys, ported blowers add power to the cars. They have to balance power, cost, competition, warranty, etc...etc..... ported blowers have been a thing for the tuner community for years, and they are proven. Just make sure you are using a reputable shop, and be happy with the results.

    Yeah not sure why your hung up on it not coming stock like that
    It's the same reason it didnt come with a smaller pulley stock...
    Same reason the throttle body isnt bigger like the ultracharger is.
    They're in the game of balance and reliability. Not maxing the performance of
    one said platform, or else there wouldn't be mods for any manufacturer.

    Edit: Porting the supercharger may have not huge gains on a stock 3.0. But
    If you start adding stage 2, an ultra charger etc... then yeah it makes sense because you've now changed the motor and its performance. It basically becomes a supporting mod for the changes you've made, not the stock platform
