Myself, I think there is a lot more to be said for a big power number that is extracted using knowledge, engineering, and technology.
Ahh, you and I are perfect agreement here.

And who is to say what knowledge, engineering, and technology is acceptable, and what isn't?

A better question IMO is: what does this result teach us?

Apparently, the definition of what's acceptable depends on what axe you have to grind, or IOW in these forums particularly, what ("non")vendor you choose to shill or bash.

I also prefer the no drugs approach and always have, however, who is to say that it doesnt take skill to run nos? Sure one can pour it in...and one can also crank up the boost...or put in the biggest pistons they can find...these are all easy no brainer ways to power....but, when properly applied...nitrous can be a great benefit and safe to use. In the past..they old methods have been used extensively. Just like cranking up boost. But soon, I suspect folks will use proper nos controllers and multiport injection along with the correct fuel mapping to make nos use safer and more acceptable.

Nowhere was "acceptibility" brought into the discussion. It was simply stated, "there is a lot more to be said for ..."

There is no axe to grind.

I think you're reading more into my statement than there is. I'm not even saying that I'd never run nitrous. What I am saying is that I see it as a last resort when I've exhausted every other idea. There is no doubt that it is effective, but I'd find it more gratifying if I gained 10hp the hard way than 50hp the easy way.

yea it does more for cooling EGT's than it does for more power on these, lol..
Cooler EGT gives you room for more power. Thus water/meth can do more than just add ~10-15hp right off the bat.

Take TDIRacing's dyno, for example. He gained 13hp in a very wide RPM band by just adding 50/50 water/meth:
http://forums.tdiclub.com/showthread.php?t=194165

He mentions that his EGT used to peg 1600F at the end of a 4th gear pull, but since adding water/meth he could just touch 1400F. It might be feasible to see another 5-7hp by adding more fuel. Or you can raise your RPM limit while the EGT is slower to climb, which might give you an advantage on the track.

The power gain could total 15-25hp with water/meth and a retune. It doesn't matter if you consider water/meth a direct or indirect power adder, it is still a power adder. If you only want cooler EGTs otherwise, why not just reduce the aggressiveness of your tune a bit and you don't need to bother with water/meth?

Mark do you think by having only regular windshield washer fluid from Walmart in my W/M reservoir mixed with 1/2 cup of destilled water at the Dublin dyno I got between 15 and 25Hp more? I doubt it.

I have had this W/M sytem for about a year now and the main benefit from it, is that my car sees lower EGT.

I am not skeptical, but I'd love to see a car with a dyno of 200hp engine only , then you install a W/M system then you see a car with 215 to 225 HP, that would be nice.

I would only use it to keep egt's down on extended period of high load, like in circuit racing, if you go to wild on the methanol side of thing, it's getting risky..

my car has over 240hp from 3200rpm till redline, and I went on a 30° hot day doing some 30min sessions of circuit racing, egt's never got over 850° without w/m or spray.. airflow my friends, thats what you need.. then you can use some bandaids if thing get somewhat hot here and there
