I recently added water injection to my car. No methanol in mine. My sole goal was to make the motor safer by reducing intake temps. My max intake temp so far recorded was 117, and that is with a GM itake air temp sensor located in the intake manifold. That compares to a pre cooling # of in excess of 160.
It did gain me about 13whp with just the addition of the water injection and tuning with no other changes.
I used the coolingmist system and it seems to be working well. I haven't really tested it much, but am taking it to the track this weekend and will see how well it works out.
