  1. Dude...you so need to get AIM...now!!!!!! <A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/smile.gif"></A>
     
  2. Dyno the cars side by side. 5 WS6s and 5 Trans Ams.

    Do it 5 times each, for a total of 50 runs.

    You won't see enough of a difference to overcome a standard deviation between the cars.

    They will both throw between 305-315 horsepower to the rear wheels, and there will be no confidence to support the WS6 making more power.
     
  3. the only real gains that are experienced from any sort of "ram air" intake are due to its colder intake charges. if the temperature variation is eliminated, there are no real life power gains. when you see all these kids surefootedly standing on their opinion(and thats all it is, an opinion, but certainly not factual) that ram air has another advantage(eg that of creating greater intake pressures that are actually advantagous and noticeable) you realize just how well of a marketing strategy it is.

    just how coca cola made santa clause, detroit made "ram air" to be something and now a whole bunch of kids believe in the myth<A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/tongue.gif"></A>.
     
  4. Well the fact that dynos are done with the hood up doesn't really do anything either <A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/wink.gif"></A>
     
  5. Mine was directed towards the first post
     
  6. on a dyno, the car is not in motion, so no pressure build up is in effect, duh<A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/tongue.gif"></A>.
     
  7. they put a big fan on though.
     
  8. Yeah man thos fans push A LOT of air man
     
  9. That's what I was trying to say...pointing out the RAM AIR hood is useless when doing a dyno run....goofball.
     
  10. sarcasm is hard absorbed on the internet, dont you agree<A BORDER="0" HREF="http://www.supercars.net/emoticons.html"><IMG BORDER="0" SRC="http://speed.supercars.net/pitlane/emoticons/wink.gif"></A>.
     
  11. I knew I had read this before, and I found it last night (in Excellence magazine). Which says that Ram-Air using pressure does exist, and indeed, work.
    The 2004 Porsche 911 GT3 RS uses a ram-air setup behind the rear wheels to create up to 1.24 Bar intake pressure and increases horsepower by 15-20 HP around the top speed of 185 MPH. This is direct from PORSCHE Motorsport, and if I am going to take anybody's word on this subject, it's going to be them. This sparked another memory, and I found out that the front intake on the Prodrive Ferrari 575 GTC racer does the same thing, with about the same numbers. That's Prodrive, one of the world's foremost racecar builders, and PORSCHE Motorsport the worlds foremost production-based racecar experts saying that Ram-air does in fact work.

    More than good enough for me.
     
  12. Well in the beginning (I haven't wasted time on this entire thread) the point was that ram air was useless on the street. No one denied gains of power as you started increasing speed to 100+ MPH.
     
  13. Congratulations on 15 horsepower at 185 mph. Good luck using that.
     
  14. I'm only refuting the statement (that I also made), that the entire idea of Ram-Air isn't possible. Pointing out that you can have increases in HP through increased pressure in an open environment.
     
  15. There point was that it was useless on a street car. Its just a gimmick.
     
  16. here is an interesting question though, in bike magazines they usually quote 2 horsepower figure for a given sportbike, say ZX-10R Kawasaki, with 171bhp normally, and 180bhp with ram air....now how do they go about measuring that....

    BTW according most calculation, the effect of ram-air at speed is about 5% at most, one can see it being of some use on the race track as it does give you that much more power to push it compare to someone who doesn't have it. But the effect is negligible in most situation...
