    No worries at all!
    i' ll be here waiting for yours results.


    My personal advice is to install it and keep going in normal way for 10 days,
    after to put back on the stock intake and see what happens,
    may be someone will not be able to feel the improvement installing it,
    but everyone will feel the car going slowlyer than with Puffo once it will be removed!.

    +1 :)



    Take my advice:
    let's wait for what Patrick will discover,


    Patrick's Puffo left last evening at 5pm with a courier,
    it will came hopefully on friday,


    It wll takes 7 minutes to be installed and i think less than that time to provide firt prove of it's efficency.


    I hope so next monday everyone here will know what Patrick sais about it.


    I already sent a little Puffo intakes on 3 continents,
    ALL the F20c feedback untill mow have been good,
    i'm confident this will be good as well.



    Letìs make popcorns and wait. :)

    this was also my apprehension


    but for me personally it's no problem with the AEM ECU :)



    I'll wait for your tests results!


    I hope you 'll recive it before the week ends,
    let me know.



    Clearly, no worries!

    it seems that at the newer models the IAT is located in the intake tube, not on the intake manifold
    but if you re-locate the IAT on an older model, you'll need a programmable ECU right?
    if i already have a programmable ECU i don't need to re-locate, because the map can be optimized


    is this correct?



    excuse me,
    why don't you open a proper post?


    i relocated a sensor from the stock air box in a different position tryng to stay closr as possible to the prewious position and i had no problems in 6.000 km,
    i did same with near 25 S2k with same results,
    are you sure the problem is that??




    I think you are right!



    Ok,
    this is something i can answer!


    If you have a temperature problem i don' t think i found the solution,
    becaue the air inside the intake is colder because it comes from outside the engine square,
    but it's still at external temperature,
    so, best i can do as results is comparable with an Airduct,
    maybe just 1 or 2 degrees colder because i don't have a hose withc get hot near the radiator,
    but i have to say i don't trust my "deltas" enought to say "buy Puffo",
    the best i can do is to give you one to try,
    if it will fit your problem you will pay for it,
    if not you will send it back.



    I'll trust your tests,
    i'm confident you will be honest in same way i am,
    because passion is just passion and nobody earns over others head.



    for the first questio,
    my personal opinion is Honda didn't design a proper intake because they had to satisfy laws about noise and pollution,
    if you open a stock element you will find inside lot of stuff designed to just keep low noise,


    i don't think i "improved" my car, i just "restored" the intake in a way it should work.


    As i told i'm sorry about the wheel line because i didn't print,
    in next dyno day i will do it with old prints too,
    just for the records:
    my stock print used to have 176.4whp with stock intake,
    the other results are printed.



    i think too an encrease of 9.5@50km/h just proves stock component is not designed for top performance.



    for the other question:
    i do but i didn't print them because without fan the gain is just little bit more than ZERO,
    178whp and not anymore 190!



    Maybe i started in the wrong way here,
    i was just saying there is a massive difference between the stock intake and a dynamic one,
    i don't think i' m a genius, just i realized Honda didn't did it's best this time.


    i'm also designing my own exaust because i calcolated it and this time too,
    my results are differents,
    so i just thinked if last time i gained 13 more Whp,
    maybe this time i will gain 5.





    I really appreciate your point of view,


    i heard many people talk about ram air effect,


    i just said : "Puffo works, givr it a try and let's talk again about it".



    By the way:
    dynos were tested wth closed bonnet and 100km/ air fan,
    but Davide tested it against his prewious stock intake with just 50km/h air,
    and he did 9.5+ hp with Puffo.


    ASAP i'll post this print too,
    made in another town from another dyno and showing the same results.

    Maybe i' m just too stupid but i still don't get the point.



    One day in August in italian S2K forum we were complaining about the costs related to improve the S2k power output,
    because we calculated to improve an S2k in Italy used to cost at least 50 euros/hp for the first 5 ,
    at least 100 euro/hp from 6 to 10 hp and untill 150 euro/hp past 15 improving hp.
    so we decided to try something new.


    i' m not talking about RAM effect, just about Bernoulli's equations and Reynolds's rules,
    because if you can provide more air the car will go better,
    as we tested with GPS on track and motorways, OBD testing and in the end on a real dyno with 100km/h air fan,
    In truth i don' t really understand what's not clear in the prints,
    but maybe it's just because i was there.


    i apologize about the fact that in the first dyno day i was just testing in a private session the improvements and i forgot to print all the lines,
    because using same car in same conditions the green line "dissipata" who means "lost power" was pretty much the same in every case,
    and as everyone knows a dyno calculates the "engine power" adding wheel power and lost power,
    but for example in "Baru's tests" you will have a single line every paper and you will be free to compare.


    I' m not here to cheat to anybody,
    even if i hope to have as soon as possible the first german dyno,
    nad i hope they will confirm like every other done untill today, it should works in Germany too.


    i was just trying to share my stupid invention,
    becaue to improve the car in a sensitive way without paying enormous money is now possible,


    I don't know how it works in Germany,
    here in Italy to have this kind of improvement you have to spend more than 1.000 euro,
    i just want to let the world know that having the same results for 1/4 of the requested expense by famous brands sets people free to choose:


    i mean,
    if you don' t want to spend that money for a branded dynamic intake from today you don't have anymore to.
    That's it.

    Gramigno Patrick is our "RAM-Air will never work in any car with no intake at any time in any place all over the world" guy.... :)


    patrick Nice try :) :)



    Thank you!
    now i start understanding.


    I use to have the same doubt before we stated testing.

    I REALLY apologize!!
    i was 100% sure to have posted this page!


    so sorry.


    Here you are my prints and comparison;
    Just the studies have to be private, not the test.

    According with tje "Plate number":


    Gramigno :
    test of several intakes fitted on the same car (stock 2004 with 40.000 and just custom friction eliminator.



    al the other car are:
    resident intake vs Puffo.
    on the prints you will find a descrition about cars setup.




    I don't get it,
    maybe because of my low english skill but i must have misunderstood the question because i don't think i was asked to do the same thing,


    in the case of PWD they didn't prove,
    i did as you can read from the prints in first page,
    (i posted more test results than everyone!)


    The question i'm not going to answer is about "how did i do",
    because i didn't made it by my self and as i told i' m not allowed to share the studies,
    and thath is not on the table,


    I'm not asking anybody to trust or belive me,
    feel free to don't, even reading the dynos posted in first page,


    The question now is:
    why should i share the studies?


    Because i'm an italian my first answer will be:
    to save 300 working hours and do themself their own intake.


    and trust me about it,
    i'm not going to make it easy.

    Gramigno.. I understood from s2ki that you did some fluid dynamics studies of your design.


    Do you have some comparisons of pressure/speed (volume?) of your design vs the OEM box?




    I do but i' m not allowed to provide them.
    i' m so sorry,
    product is available, but unfortunately studies are not,
    because of respect for all the people involved who pay the bills with automotive evolution.



    I apologize about that.



    Thanks mate,
    i'll wait your performance test.

    i can provide lighter to,
    untill 1.6kg but i'm afraid that will be very fragile.



    if someone is interested to light version let me know,
    but i have to say i don't know if a light version will survive to international shipping.

    Package isn´t here, be patient, volks.
    But: we won´t be able to test the puffos before march.
    If that is too late, order your own one ;)





    nice to read you!
    please let me know when it arrive, so i can have an idea for further expeditions.


    Thanks!
