I've got a question and this looks like the place to ask it.

Can water/meth be used with nitrous so that the normal timing retardation nitrous demands is avoided?

If so would the best nozzle placement be?

 

there would be no reason to use water, the state change of nitrous cools the intake charge.

You would want to use pure meth or race gas, as a secondary fuel system for the nitrous. I think race gas would be better in this case.

If or not it would still require a timing retard would have to figured out through testing

 

I wasn't considering it as a charge coolant as I knew the nitrous is far colder, I was thinking in octane boost terms only.

IOW, I'd like to keep the current timing for better power less than WOT
but don't want to spend money on a retarding unit for WOT. I thought water could compensate?

 

water has no octane, it does not burn
