they say it burns good i like the guys at Ice injection, running a blown 565 at 14psi making gobs of horsepower and a mild hyd roller cam! 300+ hours and still ran great? That sounds like a winning setup!

the stuff works great, as stated just run windshield washer fluid, works awsome, I actually built my own kit 40 years ago on a supercharged S/B ford street car I was playing with...thinking about doing the same with my pro-charger

Different application than what you guys do. If the red lite comes on, the system is still safe as the procharger was designed to run at 5PSI. Its just an insurance policy.

ya that wouldnt be a good thing! Would plain water be suffice as a supplement to cool things down, or is methanol a necessity on a low boost app? I know some kits do the mix of water/methonal (windshield washer juice)?

They spray straight methanol in those engines. Rudy just pulled them out with 300 hours each because "it just seemed like time". Leakdowns are still great though.

You can use water or meth, or any combination of the two. I personally prefer to use straight meth for performance reasons, but water does have some advantages... such as cost, availability, and lack of flammability. Windshield washer fluid typically has about 15% to 20% meth in it and works fine for most basic applications. Whatever you set the system up for, you should stick with the same going forward as the AF ratio of the engine is often tuned around the meth system... well at least it should be to get the most out of the system.
All the systems I've setup use a GM MAP sensor and a progressive controller. You can set the turn on point, the rate of ramp up and the pressure. With a system like this, kicking the system on at 3 psi and ramping it up from there is easy and pretty seamless up to max boost. But even a very basic system can be done w/o the progressive controller, but you dont want to kick it on too low and it leaves some power, tuneability, and control on the table.
As mentioned, it's not hard to add some safeties in the system. The safeties become important as you start adding more and more meth (it becomes a significant portion of your fuel needs and a failure would cause a lean condition). Some may say, just tune the engine w/o the system and then spray on top of the existing tune. The problem with this is it fattenes everything up and you lose power as the mixture gets more and more rich. IMO, the safest way to use this is in small quantities. It doesn't take much to cool the charge and add a little octane (if you're using meth), but with a small shot of it on an engine that is tuned for it will not lean it out too much if the system were to fail. BUT, after you see what a larger shot of straight meth can do over pump gas, the rewards can be HUGE when everything is tuned for it. My street car can make 1200+ hp with meth and pump gas... I'd never try it w/o the meth! I'm sure I could push it further, but no need to.
Meth injection has a ton of potential and works amazingly, but you have to understand a system failure would need to be caught quickly or it could cost you your engine in a matter of seconds!

I like to think of them as a good tuning tool, but I wouldn't bet my big dollar engine on just an aftermarket KS system!
