Lets Talk Water Meth Injection

[The Mafia]

As a tuner, I prefer not to use it. It's too unreliable and a lot of people tack it on without any safeties. When the kit fails, you get a massive amount of detonation which is more than enough to destroy a motor. I have seen cars come in with clogged nozzles. How long they have been beating on them - you have no idea. It could throw a rod on the first dyno ramp. Once again, no idea. A lot of these people also have zero motivation to service the WMI kit - cleaning nozzles, testing them etc. 

If you insist on using it, I suggest these as a minimum:

- Aftermarket ECU with proper safeties set up
- A FLOW meter, not a pressure sensor wired to the ECU and protections set up. no flow = no boost and timing. 
- Decent lines and pump
- A proper solenoid nozzle that supports PWM and has a very good spray pattern

Tuning will cost a fair bit more but it will save your engine.

Basically everything you described + the annoyance of keeping all of that stuff working is bad enough that as much as I'm in love with the idea I can't bring myself to actually do it.

E85 is so much better. Even in E40 form. It's shame that you don't have access to it. 

A water meth kit can be made reliable but it takes a few sensors and a decent ECU like the Link G4x.

I have E85 locally, the US loves subsidizing corn and corn ethanol. Also we've banned basically every other octane booster at this point so ethanol is the only thing that you can get for a reasonable price. I plan on doing flex fuel eventually.

Still working fine, albeit, my 33 doesn't get used as much these days,

If you have E85 available at the pump, that would be my go to option. If you don't, like us in Canada then WMI becomes very interesting and is safe to use with proper integration and safeties setup.
