 WTF is going on with the sight now  I had MR Yuck runs a sixpak with the Snow water/meth injection kit on this post when I posted it last night

In this day and age of varying gas qualities, inconsistent ethanol content and regulatory changes, water injection may well at least protect our engines if not add a significant level of performance.
I am seriously considering making it a part of my next build. I run 11:1 on pump gas and things are good.......most of the time. But the engine is on the edge and occasionally I need to back the timing off because of gas even though I gas up at the same place. (93 octane supposedly)
It appears that meth/water injection can produce real performance improvements in certain combos. The water injection just may be a cushion that allows for a tighter tune without being on the ragged edge of destruction. That alone would be worth the price of admission.
Master, again and still

there have been several cars on my friends dyno that had water/methanol injection. it has wasted his heated oxygen sensor on the dyno several times.
it can help if you motor is built for it and you know what how to use it properly.
basically with W/M injection it cools the intake charge allowing you to run more timing and compression for additional power.
it can also be used in boosted applications for more power. it really helps boosted cars without intercoolers.

'Race gas performance on pump gas'...
The eternal chase...
At the end of the day, I think I'll make my life easier...
Like I have for a lot of years...
Throw in a little CAM 2...And be good to go...
I have no desire for incessant cam changes, head changes, compression jockeying, timing issues, carb issues, temp variations, pre-ignition, detonation, octane issues...
And on and on and on...

I had a few people suggest this product when I was dealing with detonation in my Charger. I have no room to use a spacer plate type system though since my air cleaner is 1/4" from the hood. Running 11.0 or higher compression ratios mean that you can't ever let your guard down.
I decided that being on that ragged edge of detonation for a few extra HP isn't worth it to me.

, it defies logic that drawing a non fuel substance (water vapor) into an eng would give you better mileage & from the looks of it I wouldn't think it'd even draw much vapor at all & even if water vapor did help you'd have to heat the water somehow to get it to turn to vapor
know who that was?) ....
I have used methanol with race gas years ago in a bracket car before the Snow system was available 
To directly answer your question on how to step up performance on amotor to make it runs a sgood as a race motor on race gas there is really no way to do that, if you make a big C.I. stroker motor designed for pump gas you can, and I have, make a hoop of power 
Once I added a set of ported Eddy RPM, Harland Sharp 1.6 rockers and up the compresion ratio(10.29 to 1) to use the aluminum heads on pump gas it made more power and torque
