Dear Sir:

I actually have a Devil's Own Water-Methanol System installed on my Mazda B2500, naturally-aspirated (no turbo) diesel pickup.

The regular system is controlled by a pressure switch which turns on the water/meth pump to FULL Delivery when a pre-set turbo-charger boost pressure level has been reached.

In my vehicle (that doesn't have a turbo), I installed a MAF (mass air flow) sensor from an Ford F-150 pickup to supply the correct signal (0 - 5v DC) for a computer control that can vary the speed of the water/meth pump with engine airflow.

I bought and installed it myself after taking several test drives with Bilal (DevilDoc) at the product demo and introduction in Clark, Pampanga - that's where I met Ramon (Budoy) from Central Diesel.

He's (Ramon) a pioneer in the use of water/meth injection on his blue Isuzu Trooper - but his is a more conventional installation on his turbo-diesel unit.

The local dealer is Speedlab (across from Pegasus!!!) along Quezon Blvd - not far from Central Diesel - look for Fernan Lao.

My system cost me about Php 25,000 all in all with the pump, lines, connectors, nozzles, computer control and MAF sensor, etc.

I use a small 2 liter plastic tank (originally containing soybean oil) for my water-methanol - thats good for about 1 hour of high-speed running on the highway and 2 hours in the city.

I've been using it for about 2 years now.

I've found that with natural aspiration, you have to use more than a 50/50 water/meth mix - in fact you have to use very high methanol concentrations to get good results.

You also have to use very small nozzles or the engine chokes.

When its working right, it will allow for better and stronger acceleration, and stronger top-end.

It definitely gives more power all across the power band. That extra power is not dramatic, like a turbo, but it definitely has an effect especially during passing maneuvers on the highway.

Of course I had to undertake several other significant modifications to get it to work just right.

I use it everyday, most especially when going out-of-town. Note that the settings for city use and highway use are different, so you have to change over for the best performance.

An added bonus is that water/meth injection not only adds power but improves the fuel economy - on and off highway.

Right now I have to replace many of the connectors which are leaking, clean out the pump and replace/renew the seals as well as clean the nozzle which got plugged with dirt.

All of that cost me about Php 1000 (not including my own labor).

If you were to ask me now that I have a lot of experience I would say that it's worth it - IF you have tuning skills and patience to fully exploit and develop it's potential.

That's a pretty big IF, otherwise stick to the simple turbo version.

Oh yes - the cleaning thing - its not so dramatic on my system as I use very small nozzles and the MAF and computer control makes of a progressive delivery - reducing the cleaning effect.

That said, the engine is crisper and smoother AFTER using the system and there is NO smoke or particulate emission to speak of when it's on - during my emissions test, the guys tested it 3 times kasi super-baba ng opacity reading.
