I know DLM uses water injection on select blower cars. Seems to work well.2die4 said:Why doesnt anyone use Metanol/water injection to avoid detonation in the cars ? seems like a waste of money to put in forged pistons if you dont have to . The met/water kit could be set to start inject at say 4 psi and it would never detonate its like driving on racefuel all the time. In turbo applications met/water injection is very common to get lower EGT temps and to avoid knocking detonation. And its nothing new they used water/met injection during WW2 in the fighter planes.
