Founded in PM, any of u guys heard of this?

aquatune?

 

That link doesn't work.

 

ok try this one
http://www.aquatune.com/index.asp

 

Both links work for me... I wouldn't believe any of it though!!! Maybe I am wrong though. Maybe it does work??? I just don't believe any of those places that try to sell stuff like that!!!

 

In my short experience, if it sounds too good to be true, it probably is. Wait till someone who knows what they are talking about to get on

Usually Red or Random will know these things.

 

Yes. Water injection sounds crazy, but it does work, most effectively on TURBO cars. What it does is it sprays a fine mist of water into the intake stream.

Since water has a high specific heat, the water cools the intake charge down so that more aggresive timing, etc settings can be made for more hp.

 

Yes, Water injection can be a wonderful thing, but in most cases, it is a "band aid" fix at best.

The water lowers the tempature of the intake air charge by mostly evaporating. The small portion that is NOT evaporated, contacts hot metal parts and cools them down. It also raises the effective octane rating of the fuel you are using, allowing you to either run lower octane gas, or turn up the boost to higher levels.

It is refered to as a "band aid" fix, because it is really only useful in cases where you have detonation problems. Too much boost, improperly designed combustion chamber, or too high of compression ratio, or improper tuning. It is a "cheap" fix, but in reality, a good dose of tuning, or a properly built engine will elimate the problem.

If you use such a system, you must use Pure distilled water. If you use normal tap water, all the crap disolved in the water is going to end up eventually coating your engine parts. NOT GOOD!

It is normally only used in very very very high strung, very very very high compression N/A motors, or in Turbocharged or supercharged cars.

If you ever run out of water...boom goes the motor.

I used to use a similar thing with a pinkish water substance on my 65 mustang 289v8 ( back in the 80's - I was 17 then, 32 now).
It had high compression heads and ran on regular gas ( remember that stuff) which could only be had at 87 octane.
It got rid of my pinging, etc.
No use in a tib I think,tho.

 

It looks like a cheap substitute for a real water injection syste. Might as well graft a milk jug over the intake manifold a make a couple of small pinhole in it to let the water drip in.

Although a band aid, water injection is contraversial.. the high power boys are divided on whether to use it or not. I use it on one of my cars and it does let me use a little more boost but it is only a band aid because I can't seem to get the fuel mixture exactly right.
But on my Haltech RX-7, I have complete control of fuel and timing so I avoid it.

If you really want to use water injection, I think the best is aquamist systems.

 

Spearco also has a boost based water injection system that is rather cool. The higher the boost, the more water it squirts in.

Some people swear by them, others hate them. They DO serve a purpose, and they CAN help a motor to make more power. But in general...it is better to make the power the "right" way, with a properly built/designed system rather than trying to MAKE the system work by squirting in water, however, you gotta work within your budget!
