Hello All,
I have a early 99 7.3 SD. I've been looking at water/meth injection kit from Dieselsite. Is there anyone that could give some feedback on how they like their system and any pros and cons.
Any info would be greatly appreciated.
Thanks

Cookie88 has recently installed the water/meth injection system. Send him an e-mail with your questions.............

 

I love water injection. Other than the initial cost the power is practically free. The main reason I bought it was for the lower EGT's, but the power it add's is a nice kick in the pants too. I have yet to experience any downsides. I suppose since water doesn't compress that one could get into trouble injecting too much water at too low boost pressure, but I start the first stage at 15 psi boost with 130 psi pump pressure and it works great.

I don't know anything about the snow performance system that dieselsite sells. My DPS system has a reservoir that is at least four times the size of the snow kit, my pump looks bigger...hard to tell from the picture, and my system uses all heavy duty weatherpack switches and connectors (similar to OEM) with braided steel pressure lines. IMO it is a superior system.

Sounds great. Now the wallet gets a little thinner.
Thanks guys!!!

I used the DPS system and I LOVE it!

 

How difficult are these systems to install?

took maybe 1 1/2- 2 hours

 

Thanks BBBxcursion

 

It took me quite a bit longer than that. Since I have a six speed I could not use the suggested mounting location under the hood, nor could I route the wiring through the firewall as easily.

 

Does anyone know of a website that sells water injection kits? And does anyone know any "for-sure" performance numbers on what it will do to an engine, paticularly the 4.9?

 

Look at the third post on this thread.

 

I've seen a mixture of 15% meth mixture make 50 horsepower on a turbocharged 6.9, thats what sold me on the kit. The website I posted claims a 40-90 HP improvement for the PSD based on the % meth used and injection pressure. I have not put mine back on the rollers with the water, but the claim is easily believeable for me.

 

Guys, find the Water/Methanol Injection thread in the 6.0 area, get a cup of coffee and read through it. You will learn ALOT. Its over 800 posts long.

Both I and BigHoss550 are already running the system (Mine from DPS and his homemade) and Choctaw Bob is in the process of installing his.

 

I hate to be repeative but, what i want to know is will water injection help my nearly stock 96 4.9. I just want something that will add a quick boost to help blow the 4 banger rice burners away. BTW my only current "performance" upgrades are KnN air filter, and a single in single out flowmaster.

 

Water injection on a N/A straight six??? Risky. Powerstrokes really don't care for the water below about 15 psi boost. I would think with zero boost the water might just put out the fire. Then there's a risk of timing/detonation issues, and or just blowing the thing up froma hydro-lock.

IMO it would just be easier to slap a 50-75HP nitrous oxide shot on it and call it good.
