Alky injection has helped me to go from a 3.4 pulley on the street with 1-2 KR to a 3.1 as well as 3-4 degeees more timming with NO KR.. and testing on a 3.0 to be determined.Recent Dyno testing has shown that while alcohol/water injection may eliminate KR it seems to produce less HP then without it. My theory is that the water/alcohol is displacing the fuel providing less power and the reason KR drops is because their isnt as much volatile gas in the cylinder to be touched off by hotspots.

You run the risk of relying on your hoemade chemistry kit to not fail, and provide a predictible layer of protection...
When you add water or meth to a mixture made up of gas and air, you have to be displacing something!! 9:1 A/F..come on now, no one though to lean it out to maby you know, 12.5? Why give up so soon?
Now the real question is:
is it SAFE on the eatons?
I've heard from alot of reliable and experianced people that W.I. and WET nitrous shots are NOT safe.
The strange thing is, a DRY shot can be used on 03s with no side effects....other than pure speed...yet they share our same blower, and possibly, an IC...
I was referring to Safe as ( Safe on the blower ), I was trying to speak about the blower. I agree 100% that wet is always a better way to go with nitrous.dvldoc said:You can tell Rafler runing 12.2's with no IC and and water injection with a gen 5 blower how unsafe his set up is. Wet nitrous not safe???? who says this.
Try runing a 125 dry shot in a GTP and see what happens (BOOM). I have used a wet nitrous set up for 2 years. Look up the ZEX dry to wet conversion on clubgp. That's my little ideal, you pick up almost 25 hp to the wheels just by adding the fuel side to the zex dry kit. I went from 12.8's to 12.50 with the same size shot. And that's when I was running 13.3's on the motor.
Without a true wideband you A/F ratios on alky are going to be goofy mine read -8, and the 02's are 920, now how is that pig rich? As far as a wet nitrous set up it the safest and best way to run it.
I wouldn't exactly call alky injection a homemade chemisty set up, it's been around since WWII and works perfect if you get the proper parts.
What if you IC pump fails at the track (none are as good as a shurflo pump) Your F*cked especialy if you bumped up your timing and didn't add race gas. A shurflo pump can pump out 100% methonol without failing and will last for years. How many IC pumps have failed on people? Many within only a few months of owning them. (A Freaking lot of them) So you can see you run a risk with either system.
I've had a ton of success with nitrous and alky, my rotors look like chrome but it hasn't effected my perfomance at all. The vapor action of the alky/ water injections creats a steam seal at the rotors anyway.
Your missing the biggest point of this discussion!sr71rgl said:Everything I've read says H20 injection works. It's worked on WWII airplanes and worked on 1987 GNs and Turbo T's. The one thing that stands out in my mind is the people that knock H20 are the same ones that want to sell ICs. Lets face it folks, there's more $$$ to be made selling ICs than cheap/easy to use H20 injection kits.
Can you post pictures of your install?dvldoc said:It works just fine on my car, You were probably using to high of a concentration of Methonol/H20 I run the walmart -30 washer fluid and the car rips. Since the track has closed I can only use my G-Tech to give me my times. It's has been about 1 tenth off and 3mph over the tracks timing system since I've had it.
I busted out a 12.81 and a 12.78 on street tires about a week ago. I use to run 13.20's and 13.10's on street tires before on my old propane injection set up.
So it works just fine for me, I've been kicking the crap out of the local Vetts and F-bodies and I love it. It's the best mod I've ever done. It's just a matter of tunning. I'm thinking about about adding a small nozzle in the intake manifold for further cooling so I can drop down to my 2.7 pulley for the streets.
brad_wants_you said:can you inject methanol into your engine using the standard fuel injectors. due to my limited chemistry knolledge methanol or ethanol shouldnt rust or eat away at the injectors. if so you could control the exact amount of methanol into the engine. could you use a fuel pump to pump alchol. you cant pump water as it will rust the injectors. if you wanted to race the car could you just fill the tank up with ethanol and tunr the boost up on your turbo you could get heaps of boost with no pinning
