    I've designed a wet Nitrous kit to fog just below the throttle body (under the air filter box) and above the intake manifold. I have no data points about nitrousing an Atkinson cycle engine such as the 1NZ-FXE 1.5L found in our Prius. I'm afraid to try it out for the obvious reasons; blowback, power split device (CVT) detsruction, etc. Does anyone have any wisdom to add before I possibly blow the head off my car and catch my house on fire?

    Any wisdom or advice? Yeah, don't do it!! I have seen more destroyed engines caused by nitrous than with anything else.

    I have to question your intent to use nitrous on your Prius. It will not improve its fuel economy and will not reduce its emissions. If your desire is more power and a faster car, you are starting with the wrong platform!

    Aha yes this takes me back to a misspent youth and a Sunbeam Tiger. Loved that car. Ate 'Vets and GTO's for lunch, if you could keep the wheels on the ground.

    Oh come on, it's not all about fuel economy and emissions. Even a Prius owner is allowed to have fun! There is nothing wrong with making a Prius as fast as it possibly can be.

    I remember a while ago some enterprising young man in California wanted to build a drag car out of a Honda Civic. Well, all the muscle car guys laughed and laughed and said something like, "you are starting with the wrong platform!" Well, here we are in 2006 and there are Civic drag cars that are getting 700 hp out of a littel 1.5L engine adn are getting quarter mile times under 10 seconds! All those naysayers had a tasty meal of their own words.

    Go for it Escalade, let's show the world how fast and how much fun a hybrid can be! Don't let the man hold you down!

    Now as far as nitrous in Prius, well, I really don't have any practical advice. If it was a 4.0L pushrod V6 like in my Explorer, well I could help you. The Prius... well, I'm not sure. All I can say is GOOD LUCK!

    [dream mode on]Boy. I'd love to see the face of the Vette dragging behind my Prius when I light up the NO2 and he sees flames shooting out of my exhaust.[/dream mode off]

    I pass just about everyone on my 100 mile daily commute. Yes, I pass vettes, BMW's Mercs, etc. It's not the car, it's the driver. And if you're thinking about NO2, you are probably a pretty good driver and already passing everyone already.

    But go for it anyway. And please take videos. w00t!

    Bryan,
    I've fantasized about NO2 on my Prius too, as I feel that its really the only practical way to increase power on demand, without affecting the FE and emissions in normal driving. Don't let everyone's negative comments discourage you, as many of them won't even change their own oil for fear of voiding the warranty. :rolleyes: However, given the different valve cycle of our engines, as you mentioned, I would seek the help of professionals, like calling NOS directly, and ask if they've ever added NO2 to a Prius. You may be surprised by how many they've actually done, for all we know. B)

    Seek the help of preofessionals... Boy, that could be interpreted more than one way!

    Seriously though, good advice. I just don't know enough about Atkinson engines to know how NO2 would work.

    I'm going to do a little more modeling before I give it a shot. The "pros" at TRD (which is going away) don't see a problem with the Atkinson cycle blowback. Effective compression is still in the 9.3:1 range and the motor should be within it's design limit with a 50 shot. The sun gear is the probably the weakest link, but it too should be well within it's design limit even with a significantly larger shot of power.

    By the way this does nothing to adversely affect emissions or gas mileage during normal usage (not that I really care as I routinely dump thousands of pounds of unexpended JP-5 before taking an arrested landing in my hornet while defending our nations freedom). Eventually there will be a very large hybrid aftermarket, and we will see hybrids like the Prius running deep into the 12's within the next 12-24 months. There's really no limit to how much power an electric motor can pump out over a quarter mile. Someone's gonna do it regardless of all the nay-saying.

    Just out of curiousity, and no, I'm not planning on doing this, is the Echo engine a bolt on replacement for the Prius ICE? A friend of a friend is drag racing an Echo (!) and has done extensive modifications.

    It will bolt to the hybrid system, but you may new to make new motor mounts (I doubt that). If I remember correctly, the landspeed prius used an echo engine.

    Escalade,
    God Bless you for putting your butt on the line to protect mine.
    If you find the intake valve timing specs let me know, I want to try a tuned intake system for 75 mph.

    I asked the same question about a month ago in another thread and also got a warning not to do it like in your case.
    Pioneers must raise from the crowd.
    I gess that a dry NOS system may perform better and less complex to start with this modification, rocketing to hell ;)
    Pictures and video a MUST for the crowd recognition B)

    When I have the new spacer block finished I'll takes pics and videos. Things have been a bit hectic in the "office" lately with many new programs coming to test. I've got a new suspension kit and aero package coming in from TRD/JDM, so I'll post pics of that stuff as well when I get it all installed. Expect about a two month delay... sorry, but things are being shipped in a cargo ship from Japan. I wonder they'll wedge some product support personnel in the container as well...?

    Any idea why you are responding to a 7 year old thread to folks who may not even be current members? (I will admit that will make them less likely to argue with you, especially BT Tech who is deceased)
