with that all motor build turbo does good with vtec?

This is contradictory.

All motor and turbo are 2 different things.

Anyone tuning the car with whatever setup you have, should be able to make a VTEC transition seamless.

So technically methanol injection would be as well?

This makes no sense.

First; Nitrous Oxide is considered Forced Induction for the simple reason that it does exactly what a supercharger or a turbo does, which is forcing more air into the cylinders. This is how it makes more power, more air means more fuel; which equates to more power.

Second; Methanol is just a gas. It is added as a fuel. Methanol came about in racing for the simple reason that it is safer then gasoline in racing because it burns clear and doesn't put off clouds of black smoke. Methanol has a lower energy content then gasoline, it also has a lower stoichiometric value which results in higher fuel consumption and the extra water in it is bad for things like valve seals. Something people don't know, Methanol is very bad for Aluminum. It has a higher electrical conductivity which will cause corrosion in the fuel system and pitting of porous metals.

Third; Methanol makes more power because of it's hydroscopic properties. This makes it attract water which will result in suppressing engine knock. 100% Methanol will not make more power then gasoline; however as Speedin is quite educated with, mixing Methanol and Gasoline can create a much more potent blend of fuel.

This still doesnt make sense to me. Consider me dense or teach me. A supercharger and a turbo compress air. Nitrous doesnt do this at all. There is not one mechanical property involved with nitrous.

Methanol is as you say "just a gas." Nitrous Oxide is just a gas as well. It is not a form of compressed air. However it does create cooler air intake temps and when added to fuel is very combustable since there are extreme amounts of oxygen added to the combustion chamber. While nitrous by itself isnt even flamable.

Please sirs, do educate me.

he's talking about the more fuel results in more air being sucked into the motor. you answered your own question.

It is still not a form of "forced induction" in my eyes. Forced induction is mechanically generated, while nitrous (when added to fuel) or methanol injection is a chemical reaction when in contact with a form of ignition (flame/spark).

Air being "sucked" into the engine isnt forced induction. Youre still bringing atmospheric pressure into your intake manifold. What happens in the combustion chamber is different. That being said...... If methanol and/or nitrous is considered a form of forced induction, then regular gasoline should be too.

Unless someone can show me that adding nitrous before the intake manifold or in the intake manifold can create a pressure greater than atmospheric pressure, my arguement will be stated as incorrect information, and I will change it.

Its considered forces induction because the cooler air is compressed, much the way it would be if it was coming through a turbo or through a supercharger. Nitrous is much like liquid nitrogen in that it is compressed into its container and when its released it is very cold and it expands, so when its released into your combustion chamber its expanding with the intake air to create more burnable gas in the chamber. Does that make sense?

i think he was talking about doing a full motor build and then doing a turbo. and yes you can do that.

Yes, it does. I still wouldnt consider it a form of forced induction. Its not propelled by anything but the air that moves through the intake or intake manifold. NOTHING is forcing it at all. Charge pressures in the intake manifold are still 0 PSI.

How about we all just agree to disagree? That would work for me. I think both side were well played and both heard. So lets all just drop it?

I don't care if we have a debate, but just not in someone's thread. That's the fun of a forum. We can talk about certain topics all day. The more we talk, the more we learn. :thumbs up
