Ill be running my next water only setup with a T-78 at around 24psi. I'm just wondering what you other water only guys have ran up to. Also, please list timing and a/fs with the amount of water you are running.

I have been without a physical intercooler for over a year. During this time, I've mostly run 10 psi. I have now gone up to 15 psi and feel the need to add a physical intercooler and retain the chemical ic.
Once I have the physical and chemical cooling, I am upping the boost to 20 psi.
I use 50/50 water/meth

Straight water I've ran up to 25psi on the GT3574.....the 25psi runs were spiking though, 22-25 from 5000RPM up. I was running 10lb spring and the controller was fighting up there...
That was on 625cc with 91 octane
Now on 375cc nozzle I have run up to 20psi on a T04-R....but the clutch is slipping at that power so the car won't see it until I get my twin plate setup in there. But it was certainly safe tune wise. EGT's sub 900C, 11AFR across peak TQ, 11.4 near redline.....this was on 94 octane.
