it means its not using any method of forced induction (turbo, nitrous etc.)

Maybe so, but he also likes to do things right, so he's OK with me.

I'd dispute the use of nitrous as "forced induction" (but I may be wrong). Nitrous is simply the introduction of another fuel source into the intake charge, so we could say water or alcohol injection or the use of nitomethane would ALSO be forced induction (and that's not accurate).

I'd say forced induction = turbo / supercharger. To a certain extent, I think one could argue that "Ram Air" is (technically) 'forced induction', but I think we all generally agree that there must be some active mechanical action to make it truly "forced induction".

Because N2O introduces more oxygen into the cylinder than the engine normally sucks (heh...sucks) one can say that it is "forced" into the cylinder. That is the whole point of any forced induction anyway: forceably introducing more oxygen into the cylinder than the vacuum can intake.

huh? uh yeah... i guess i would have too much time on my hands at midnight:rolleyes

oh yeah and i copied that definiton from the webster site. i dont want any1 thinking i could type that bc theres no way i would. too much of a lazy slob to do that

EDIT: btw SmithSr, did NICO get my donation? i hope it didnt get lost or anything thru paypal

I second that one, Nitrous is a force induction method because of the reason above.

yes! Nitrous FIGHT!

it's not soo much considered forced induction as it is usually just noted as a power adder.

when talking terms of qaurter mile time, you best mention it though.

Nitrous introduces more oxegen yes, but is it forcing air in? No. Nitrous is simply an added chemical in the overall process of combustion, there is no forced air about it.

Nitrous isn't really considered a fuel, unless you count O2 as fuel (which it is if you consider fuel as the complete vaporized amount of air/fuel in a combustion process).

That's a tricky one though, whether it could be considered force induction or not. It is doing a similar job of putting alot more air into the combustion chamber just as a turbo does, but I could go either way of whether it forced or not. I think the answer lies in whether nitrous, when injected, pressurizes the intake manifold. If so then yes I think it's force induction.

Shoot an email to an admin, chances are they received your contribution, and have a stack of work to do in their 'in' box and haven't gotten to updating your status just yet. Patience, my friend.

Edit: S13GUY, your email is not enabled or else I wouldn't hijack in this fashion, but how much are you asking for your car?

Edit2: Whomever it was that mentioned the term power adder, was right on. Using this term eliminates a debate over semantics!

Very true - I think the mechanical aspect is what makes the difference. Remember, water injection or alcohol injection ALSO makes the intake charge denser, but that's not forced induction.

Either way, it's cool to think about!!!

In my defense, that was posted at 2:04am and nitrous is kind of a grey area :D

well, I'd say it's more of chemical induction. However, it's a little different in the sense that it is forcing more oxygen than the engine would normally see, unlike alcohol which is a coolant and fuel as well as propane injection.

In other words N20 is adding extra mass of oxydizer (oxygen (which is not a fuel)) <in a way the same thing a sc or turbo does but with "better" results.

And alcohol or propane is adding extra mass of fuel and cooling power.

I'm guessing the term forced translates into seein air being pushed into the system, something that is kind of hard to define with nitrous.
