Has anyone used water injection to replace intercooler?

Thank you for your reply, I am now convienced that front interccoler spray does work.

0.8 second is a big increase in power in terms of 1/4 mile time. I expect it was a very hot day and you must have used quite a bit of water to have such good results.

The Autopspeed system seemed to be a good add-on for racing applictaions.
