Default Are there disadvantages to water injection.

After reading 2000SilverBullet'* post on water injection . I was intrigued by the system . My question is are there any negative affects of running water injection? And how often does the water injection system need to be filled up?

Filling depends on how much you run it. It'* not normally a practical thing to be on all the time.

Disadvantages? Sure. There'* rumors of hydrolocking, although I've never done it (on my 4th system now), and I've never personally seen a case of it in 3 years of dabbling with it and hanging on the Forums.

It takes a well-thought out system with all the safety measures considered. And alot of research on your part. Not just asking questions, but RESEARCH. You have alot of reading to catch up on, and there'* plenty of info out there.

Water Injection was first used at Daytona Beach in a car in 1909. It was also used extensively on aircraft engines in WWII.

Typical flow rates are under 300cc/min (0.08gal/min)
Most systems are designed to trigger only at the boost or load where heat becomes an issue. You would need to spend a lot of time at WOT to drain a 1gal tank.

There are countless topics here regarding WI, going back at least 2.5 to 3 years.

Do a search on 'water injection' and click the box for all terms. willwren as the author. You'll find all of them.

The only thing that concerns me is the fact that the epoxy coating on my rotors may begin to where off. Any thoughts on that?

In all my lurking and posting on WI forums and my communications with the experts, I've never heard of that happening, even spraying pre-rotor (Turbo'* can't spray pre-rotor, but we can).

Post-rotor is GENERALLY the preferred injection method, but as you can see, it can be quite difficult.

Keep in mind that water won't damage the epoxy coating on the rotors, and most, if not ALL the methanol will have evaporated by then. That'* the idea. As it evaporates, it cools the air/water mix. Evaporation removes heat.

Besides, you won't be running it that often.

Does this mean it won't hurt your rotors? Beats me. But I've never heard of it. I'll be doing it, because if it f'* something up, I'll get another used SC off eBay for $100 and start over.

LOL. I guess as long as it is vapor by the time it hits the rotors it should be fine. And back to setting my brain on fire.

As an argument for the unknown, keep in mind that MOST people don't use Methanol mixes. Probably 70% or more use either water alone, or mix it with WS washer fluid, which contains a SMALL amount of methanol.
