Here are some testimonials and install stories that I've received via email. I've literally received hundreds of these types of emails over the years, these are just a few I picked at random. I'd love to hear about yours, so click here to drop me a line!

"Hi, my name is Chris, and I found your "How To" page on building your own water methanol system. I am mechanically inclined, and I have quite the imagination when it comes to my truck and making things work. So I decided to give it a try. It damn sure beats buying a system from these well over-priced distributors.

I had a basic idea of what I needed and how it would work, then i found the site and it took all the work out of it. Everything I needed was right in front of me in a neatly laid out page with part numbers and everything. I purchased the items I needed, and installed them on the truck. (By the way, I own a 1996 Dodge Ram 2500 4X4 with a 5.9L 12 valve Cummins.) The system works great...

...I really wanted to thank you for the writeup. It made the design and installation so much easier, and I know for sure I will use this site a few more times, I have a few friends with trucks who now want a system done, and think it was a really clean job."

"So since I've gone boost I figured I'd need something to get my charge temps down. Obviously intercooling is in the works but I wanted more. Ripley suggested water/meth injection and I looked into it to find it:
-Drastically lowered charge temps
-Steam Cleaned your pistons and cylinders
-Created even more pressure to push those cylinders down

I looked at a few kits from Devil's Own and Flying Miata but they ranged from 4-800 and I figured since it's just a few simple things I could build one myself. So I did! If you choose to do this I recommend checking out My system is based on theirs with a few add ons. Either way most of the parts I used are from that site so if you're wondering about anything you see in my writup check there for the part number."

"I just wanted to say thank you for the great website! My husband and I installed it on our turbocharged Subaru and were very impressed with the overall package and how simple the installation was. Everything needed was on your site which made it easy. The kit was a great addition to the other performance mods that we've done."
