when and how much water/meth?

[tufnav]

Alright guys I'm still experimenting atm and yet to add methanol into the mix. Getting a 20litre drum soon.
Just wanting to know when you guys with water/meth injection are switching on your systems.
So what psi to switch on and
How much methanol?
I was thinking around 20-30% methanol.
Thanks guys

I run up to 40% coming on at 12psi using a 5 gph nozzle.

I did one batch at 50% thru a 14 gph nozzle and when the temp hit 720 i backed off but the temp kept going up for another 10 seconds becaus of all the meth in the intake.
Just start low and work your way up.

Ok that's good info there so my thoughts on 20-30% shoudnt be and issue on a 4gph nozzle

Run about 20 to 30 mix on at 12 psi and max boost is 19. Never got heigher than 617 exhaust manifold with chip it on setting 4. Run a master switch my 20l tank will last 6 tanks on freeway and like 12 around my local town
