hey i was reading this thing about water injection in srt-4s and it looked pretty interesting and it looks as though some real power can be made from it and it keeps the engine in good condition. i was wondering if this was just for turbo cars or if anyone with a neon might have put a kit in. if so, how is it and is it worth it?

 

On turbo cars water injection helps cool the injection charge as it enters the engine. Compressing air generates a lot of heat and the hotter the air/fuel mixture is when it enters the engine the more likely it is to detonate. You can use a water/alcohol mixture to cool your intercooler or you can spray it into the intake air.

On a naturally aspirated engine, you aren't so worried about detonation because the internal cylinder pressures are not as high. Yes, adding water to the air/fuel mixture will effectively raise the octane rating, which means you could safely advance timing, which means more power. But since you can't advance timing without standalone engine management, what's the point?

Best of luck!
