I was JUST about to post up a thread with the same question and make a polll of which kits were failing. I searched the alky section and couldn't find anyone posting up their meth kit failures.

I have seen several component failures at our shop and one customer who lost a motor after we tuned him.
One point I would like to make here is that I think many of the component failures were a result of the customer not realizing the kits they were using were not rated for 100% meth.
That being said, I have seen some of snows components fail (pump and shutoff valve) both failed because the customer was running 100% meth on components that were rated for 50%.
Other case was a customer we tuned on an smc kit that had a pump failure under wot. This one resulted in a rod through the block if I'm not mistaken.
The above is the main reason I started researching the various kits and failsafe options that are available.
A couple weeks ago I had a guy come in with a snow kit that was not installed properly (the guy with the component failures). Whomever did the boost solenoid bypass install did it backwards, so when the kit fail-safed boost went through the roof (had the solenoid on the line that feeds the lower port on a TiAl wastegate rather than the line that feeds the top port.) Add to that the fact that seals were gone in the shutoff valve so when the meth kicked in it hosed down the engine bay with pure VP M1.
Scared the @#it out of me to say the least......
I guess I say all this to just say that you cannot always blame the kit, I'm sure many failures are a result of end users not reading the included literature and installers not installing things properly....
BTW, I use Aquamist. I have also spoken with LaBontte recently and I think they also offer a great kit with plenty of options.

I was running app 700 cc/min into my suby motor, when I had a leak at my in-line filter (could have been caused by road debris, it is accessible from in front of the rad).
I was tuned for 50/50. (AFRs app 11.8-11.9)
I put in WWF cause that is all I had available. I tried to compensate by adding some 100% meth. I don't think I added enough, cause AFRs went to 12.8
!!!
Ring-land number 2 went.
Verdict: my fault for adding improper ratio of alky

Have you managed to integrate the flow sensor output to trim fuel and modify timing yet?

No,
I have not done that yet. I'm about to update my post on the Waterinjection form with details from this weekends retune..... I got it up to 350whp on our dynodynamics with 1 x 1.0 and 1x .8 nozzle running 75/25. I had a lot more room up top, zero knock from 5K and up, but it was very unhappy down low.

It was carrying knock counts from about 3500 - 4500. I'll have to look at the plots again, but it seems like it was starting when the spray kicked in. I was mainly focused on learning to run the dyno myself rather than the tuning and we had some paying customers waiting so I kept the session short. Today I will be hooking up one of the extra digital inputs on the haltech for logging the actual timing (as you know, tuning with an interceptor you cannot rely on ecu reported timing numbers unless you are just modifying fuel). Once I have the timing and flow sensor output logged int eh haltech, I'll go back and try again

Not a lot of detail in this thread, but the owner believes that the motor went due to a failure of his kit:
