Does anybody know of any and if anyone's running it what do you think.

I have run it for years and had alot of luck with it. There is tons of info on it on the Web. it was first used in planes in world war 2(pretty sure that was the one) the cons my pump had a intermitant problem last summer and before I could get it fixed .I ovaled a set of expensive head gaskets. I didn't even let it ping as soon as I heard it I shut it down.

I have not had any personal experience with it... but I know it would suck to have it run dry at full boost

I have never had it run dry in over 3 years of having one. I had a pump failure, that did suck but I am going to run it again because when you get the timming all in and the tune is right, It gives a big boost in HP on a pump gass setup.

I ran it it worked out great.I would run it again.

I heard it can cause wear in parts and like pitting of the cyl heads. and due to the corrosive nature of meth. eat away at stuff.

not at all, I have my heads off and they look just as good as they have always looked. Same heads the entire time with the meth-injection kit. It is a vapor buy the time it hits the heads anyhow.

methanol 100% is corrosive if allowed to sit in basically anything. i work with sprint cars that run straight methanol as a fuel. the an fittings take a beating over time, but theres no evidence on anything else that you arent using gasoline, other than the way the meth mixes with oil. the meth mix used in injection kits is basically the same as windshield washer fluid, and people rarely have problems with their washer fluid eating its way through anything. that being said, i had some, and blew my motor putting it into peak torque going up a hill on a freeway. my tune was probably mostly to blame, but just like any mod, its yet another area to create a problem. i would be more hesitant to use it on a street car because its much more difficult to tune for partial load jumps and many other things that arent as basic as slamming the throttle from a stop.

Pros:
Add more timing for more power
VERY cheap in the $/HP range
Can run pump gas setup with big boost = big power
Lower intake temps during hot weather (finicky turbo setups in the summer, etc)

Cons:
You run dry = blown HG, major detonation, scorched internals, etc
Can clog nozzles with cheap kits or debris in tank
Another system to maintain for your car
More frequent oil changes are needed

And corrosion only happens when ETHANOL is used, but this should not occur since METHANOL is what we are talking about here. In fact, a water-based injection system actually "cleans" the residue oil-based fuel engines leave inside the internals.

Is anybody running it on a street car with no issues. I have the anderson kit but haven't installed it yet.

you do not need more frequent oil changes with a water meth kit lol. now thats funny. You are only using this kit above about 4 psi of injection. It injects a small amount. The only issue i saw with extended street use was I lost a couple of IAC motors. because of the alch. I mentioned I had a prob withmy kit. I probably should have caught it. it is like anything else on a HP car you have to check kit operations every so often. It had been awhile since I checked mine because it always worked so good.

methanol is highly corrosive. i can send you some now-junk alum fittings from the methanol powered sprint car at the shop if you need proof.

got any headers lying around from those sprint cars, need some spreadport stuff

methanol is more corrosive than ethanol, buy far

and dont drink, not good

Don't do it on a street car. Don't!

I am sorry but that is rediculas it is designed for a street car. They work like they are designed.
If anything do not do it on a race car.

dude you are an idiot. Methanol has a cooler substance that fuel and you are able to throw more power at an engine with boost, n20 because of the cooling temperatures which helps avoid any knocking.

So i guess i better tell my friend that runs Methanol for fuel and has meth injection for cooling that he better not do it on his race car, he will go from 8's to 10's! bwahahahaa

3. they also reccomend if the car is going to sit for a while to prime your system with fuel. [/QB]

all alum fittings come annodized, its not a miracle shielding. again, im talking about the methanol-run race cars that use methanol for fuel, we'd like to not blow them up by putting gas in the lines, thats just more evidence of methanols corrosive nature. if it sits in anything for to long it will degrade it.

gaymore you are all talk ok. I have been racing and winning for years(people know me). I honestly do not now of ,or never heard of you (or care to). I gaurntee when I am done , you won't be around. If enough assholes like you keep talking shit I might actualy get this thing done .

I like water/meth injection. I was answering a question about if there were any problems with running the kit. I lost 2 IAC motors neither one was new. I have ran it for over 3 years and plan to keep running it. I started on a 302- then on my 331 stroker. I ran 2 years and over 20,000 miles on a 9.8 to 1 331. with 15 psi and up to 30 degrees timming when I raced it. The only reason it didn't blow up in the first week was the water/meth kit. The highest octane I ever ran in it was 100 octane unleaded mostly 91. If you know anything about blower cars you will see the tune I ran non-intercooled is on the edge very unsafe except for a water-meth kit. I would recomend any one running a non intercooled blower on the street get one.

As far as methonal as race fuel I think it works great. I am not sure what is up gaymores ass. In my 69 mustang I am NOT going to run a water-meth kit. It has a huge air to water/intercooler. It will only run on race fuel. I have way to much time and money invested in this car to have a pump go bad on a Meth kit on this one.

From what I have read, not in this post, the water/meth kits are great. I really want to get one, but I just don't have the money. The Snow kits are supposed to jump in price after the 1st of the year, so get a stage 2 kit now.

I want to get one just so my car will run more consistent. If I get one, my problem will be keeping the car over 11.50. I already ran 11.42 with only 7psi of non-intercooled boost and I just can't get a cage now. When I get a cage, it will be 12psi with water/meth injection and running 10's. That is also after a clutch, rearend, and maybe tranny upgrade. Too many things have to be bought to use more power. I would like the kit just because I think it would be more consistent. The day I ran my 11.42 the car slowed to a high 11 by the time I made it to the final. It slows way down when hot lapped.

My next purchase is going to be a Tweecer so I can install my 60lb injectors and ditch the FMU. With the Tweecer, you can tune the car to pull out a ton of timing as the incoming air temps go up. So, if something goes wrong with the water/meth injection you won't toast the motor b/c the timing will get pulled out as the IAT's go up. It may run a little lean though, but I plan on shooting for 11.75:1 so that will give me some margin.

I ran water/ethanol injection in my 93 Cobra for a few years, and got some good power out of it. It cut about a half a second off my times.

I built my own system from scratch using a 5 gallon fuel cell (less chance of running dry) and a high quality water pump.

I eventually removed the system for 2 reasons - 1, every time I had to smog check the car, the techs would freak out and refuse to test my car. If it's not CARB approved, you can pretty much forget about passing smog. And 2, I had a lot of problems with inconsistent flow, because it's very hard to get the tank high enough for gravity to pull enough of the mixture down to the pump. Especially when you are driving up and down hills.

So, in the end it was a fun experiment and I didn't break anything, and I did the whole thing for less than $100, so it was a good cheap project. I would have tried to tune it more, except that I literally couldn't get the car smogged.

its a deal knuckle head. i dont care for how much, ill have it covered.

bring both cars because i want to chop them both off the same day and send you home with your pump gas shit.

ill prove to ya methanol is for "Street Cars".

Let me know!
