    I have a question that has been bothering me for more than a while now.
    Why is it that almost all Ferrari owners feel the need to NOT put their vehicle on a Dyno?
    Even before I was in the position I am now w/dyno availability, I always put my vehicles (no matter what they were) on a dyno. Maybe its just me, but even if I wasnt modding something it was good to know especially the air/fuel ratio. Of course knowing HP, TQ was also nice.
    Any feedback out there?

    Doesn't seem to be much point to driving fast with out moving the car. I think most Ferrari owners see the dyno as a drag racer's tool, and not very useful for the touring driver. Also you have to remember that very few Ferrari owners do any engine modifications so the dyno seems pretty pointless. Just my $.02.

    A common misconseption about the dyno being for drag or mods only. Every car needs to be put on a dyno for the following reasons at least:
    1) Make sure your air/fuel ratio is correct. This is absolutely critical to engine performance AND longevity. Just because a check light does not come on does not mean your car is performing adequately or safely.
    2) Just because a particular model claims a certain performance number, that does not mean, first- that is what is actually making it to the ground, and second- every identical vehicle is doing the same thing.FACT
    3) Even if you are just a touring driver, wouldn't it be nice to know exactly the right place to shift for maximum performance.
    Obviously everyone is different in how they use their vehicle, some just like to drive it normal for relaxation and could care less about anything else (useless to own a performance car if that is you), but the fact remains that none of us want to hurt our vehicle mechanically or otherwise. You polish your paint- think of the dyno as a step in the same sort of owner care.

    Call me old school, but I always read mixture on the spark plugs. Learned at the knee of Lee Hurley back in the '70s. Don't know if Lee is still around, but back then he was building engines for a family named Allison.

    If the plugs look good, and the acceleration times are in line with what the factory and the magazines claim, I feel pretty confident that all is well. Now, I don't own a Ferrari, but I haven't ever felt the need to throw money at some fly-by-night 'dyno operator' who trolls for business on internet message boards. :p

    Am I missing something?

    PS, welcome to FerrariChat! :D

    Am happy to dyno the car here. In fact i personally sponsored a Dyno Day for the New England Fchat guys last year and plan to repeat it in 2006.

    Who said they fear a dyno????

    I'd love to dyno my cars. It will also allow me to compare accuracy vs. my G-Tech device.

    I usually have enough new stuff on the car to justify a trip to the dyno about once a year. I'm not afraid.

    There's a Euro club down in the area that has dyno days, I missed the last one but will definitely do the next. Curious about the output, especially with the new exhaust.

    Reading a plug was a piece of cake when you had leaded fuel. Todays fuels are not the same probably in eveyway except the come from oil. Reading AFR at the ports and tinkering on a dyno will give you every last bit of HP or torque you can get and reading a plug will get you in the ball park but thats about it and the rest is luck if you dial it in that way.

    I will dyno my car in the spring but dynos are typically calibrated for a car that has a 1:1 gear ratio in 4th. My 308 and BB are not 1:1 in any gear so the numbers will be off and you will be unhappy with the numbers you car says it makes so make sure the dyno is calibrated accordingly.

    Because I dont know you, let me say that I hope you are joking and this was written just to poke a little fun at me. If not let me answer your "fly-by-night dyno operator" comment. First of all, you must have looked at my public profile to know how I am affiliated. Secondly, I have not once asked anyone on here to hire us for services or anything ever even close.
    Fly-by-night? I dont think a dyno that is the Official for the NHRA and NDRA and has a schedule, and a reputation like ours would ever be considered fly-by-night. So please excuse me, I am very proud of who and what we are, it took a lot of hard work and dedication to achieve what we have.
    So enough about that.

    I do dyno my vehicles occasionaly for several reason, but don't really find it useful unless i'm trying to find a problem or want to see gains from engine work.
    In response to post #3:
    1) A/F ratio is usually changing in open loop, and pegged in closed loop. Even if it's not perfect, it can't generally be changed on modern cars. IMO no point in dynoing for this.
    2) If my car FEELS like it's performing fine, and nothing is wrong with it, then it's all good. I don't care if my car has 10hp less than advertised, and couldn't do anything about it anyways. IMO no point in dynoing for this.
    3) 99% of the world knows where to shift to make the car move, and i think it's easy to feel what works best. In the F-car, i don't see a reason to shift much before redline when trying to go fast.

    And, a lot of Ferrari owners likely fear that their car will not put out the horsepower claimed by Ferrari...has any Italian car company ever been honest with their HP, speed and other performance specs?

    Air/Fuel can be changed on ANY modern day vehicle !
    and what the heck does "changing in open loop" etc.. mean?
    And lastly if your car is making a pinch less than advert or other cars, you can do something about it- and it does not require mod parts, just a little tuning.

    The nice thing I will say about Ferrari is that most all of their new models that are low mileage seem to be tuned very similar. Which is something I cant say for the General(Corvette fan as well) We see ident vettes sometimes with 30 hp diff. Thats huge!!! a/f graphs are always a little different as well-timing is different- what the hell GM?
