Buckeye, you'll need less nitrous to make the same power with a pipe/porting combo...for example, if you're running a 40HP shot bone stock and a pipe/porting combo nets 20HP in addition, you'll only need a 20HP shot of nitrous.
That's only a vague generalization, since engine work changes how nitrous works and you need to tune it to your bike to prevent a dangerous situation.
Chuck, I concede to a misunderstanding in terminology.
I only have experience with nitrous in a fuel injected situation.
With a dry nitrous kit, it isn't responsible for metering any more fuel other than the colder intake is sensed by the MAF and adjusted by the computer.
Take that same kit and throw it on a carbed engine and you'll melt pistons.
So it made sense to me that a dry system like that would be the same on a carb...therefore a dry system is a terrible idea.
However, after doing a little more reading (I'm not against being proven wrong), I've found that what guys call a dry system is actually metering fuel by altering carb inputs and responsible for metering fuel as you said.
The definitions are vague and almost backwards, "contradicting" as you said.
My take...
If you have a dry nitrous system then it doesn't meter fuel.
If you have a wet system then it meters fuel, how it meters fuel is inconsequential.
Their take...
If you have a dry nitrous system, it meters fuel.
If you have a wet nitrous system, it meters fuel.
The only difference is WHERE it's metered at.
I think that's a little more contradicting than what I wrote, but of course what I wrote is wrong LOL
