Once my Vortech Supercharger goes on I'll be adding a Water/Meth injection kit to bring octane levels up to 116.
...almost zero chance of detonation
If interested in Boost protection and a little added performance,
an underhood Stage 1 Kit starts at $299
Yes, I ran Devilsown kit years ago.
I didn't have good results with it.
It doesn't seem to work well with positive displacement blowers. Running 0* washer fluid I sprayed after the maf and before the TB. It would make me run pig rich, bog down and kill my top end. Granted I never got the opportunity to get a custom tune like do now. When data logging my fuel trims would be all over the place while spraying. I wouldn't know where to start. It did kill my KR drowning my car in fuel, but it seemed like I would have to re-tune it everyday depending on the weather.
I know some of the 03-04 Cobra guys run allky, but I think most just get a bigger FMHE and/or Ford GT fuel pumps and call it a day.
It does work great on Turbo'd cars/trucks. It's a must when you want to turn of the boost.
