Water injection?

[mike85gn]

Does water injection have the highest heat dissipation abilities? I am looking at giving it a try with my hot air car. Thoughts/opinions? TIA

I am talking out of my rear but I believe a water/alcohol mixture has been shown more effective at dissipating heat and raising octane at the same time

water does indeed have great detonation suppression. But, if using straight water, you are apt to find difficulty in tuning.
