Anyone have problems with Mr. Freeze kit?

I was reading on another mustang forum that some people were concerned about the quality of the Mr. Freeze kit as opposed to the Snow Performance water/methanol injection kit. Just wondering if anyone has had trouble with the Mr. Freeze kit; either short or long term. Thanks.

I'll have mine installed next week... I'll let you know how it performs. The only issue I heard about the Mr. Freeze was that the methanol injector size was a little too big for low boost applications. That the reviews for higher boost applications made better gains.

I'll have mine installed next week too - what psi of boost are you running? I'm running a 16# pulley which should net some nice gains.

I have had mine for a couple weeks and no problems so far, just make sure all the hoses are cable tied so they can't pop off easy. I would recommend checking all the lines periodically when you first get it on to ensure no mishaps. The snow kit is definitely a more elaborate kit and I would recommend it over my mr.freeze to anybody who has the extra money and patience for the install. This is only due to the tunability of the kit, not durability. It is true that the mr.freeze kit is made up mostly of plastic pieces and rubber lines, but if its not near any extreme heat I dont see any reason for problems. It is hard to pass up a water/meth kit for well under 200 bucks with such an easy install, isn't it ? I'm only running 10-12lbs of boost and the gains were mostly in the midrange hp and midrange to peak tq. My inlet temps went way down which is always good. Different jets would make this kit a lot nicer.

I read that the water/methanol spraying before it goes into the blower will erode the impeller, which is my very big concern. The snow kit sprays after the blower, which is why I haven't heard anything negative about them.

I have heard the rumors of eroding impellers from the water/meth but I have seen no evidence from anybody yet. I have only heard about it in the context of theory and not as fact. I am not saying that it is not possible, but I would love to hear from somebody with specific experience of damage to a blower from meth injection (sprayed into the inlet). Again, I am not stating that I have proof yet that it does not damage the impeller over extended use but I also have seen no evidence to the contrary. Somebody please post the info you are reading that shows some proof of this erosion if it exists. I dont want to lead people to a destructive upgrade, but I also dont want to see people scared away from a inexpensive way to increase engine safety and power.

From what I've heard, due to the Mr. Freeze kit working off a vaccum line, it simply draws the water/meth from the reservoir and "sprays" it into the intake piping before the blower - people are concerned because how well can it spray if it's working off a vaccum line - the water/meth won't atomize as well as opposed to being sprayed after the blower, such as that on a Snow Performance kit. The Snow kit has a pump that goes with it, making it a bit more expensive but offering better atomization.

Mr freeze uses a boost signal to pressurize the tank, which then sprays water/meth into the intake based on the amount of boost that the supercharger makes. The mix atomizes fine on my car at only 10psi and the air drawn into the supercharger helps as well. I will agree that if you have the extra money for the snow kit as well as the more complicated install, I would get the snow. I will also say that for the money mr freeze works wonders and has not been proven to create any problems....only power in my case.

Also, can any of you snow kit users chime in with the amount of pressure your kit sprays the mix at. I have seen posts where some come on at only 4 psi which probably would not atomize as well as 10 psi depending on the jet. Of course, mr freeze starts spraying at 1 all the way up to 10 at the redline (for me). Again doubters check out my posts with my dyno graph to see how well it works.

Snow has a MAF kit that electronically controls how much it sprays based on the reading from your mass air meter. Here is the kit: http://www.snowperformance.net/proddetail.asp?prod=auto022 - has a 220 psi pump.

Are you installing the mr freeze or convincing yourself to use the snow kit ? You started this thread, asking people about problems with mr freeze and then just started coming up with every reason imaginable that the snow kit is better then the mr freeze kit. I have tried to show that there is no concrete reason to avoid the mr freeze kit by sharing my knowledge and experience with the kit and all you can do is come back with more statements about the snow kits superiority. I have admitted that the snow kit is a better kit which provides more adjustability and more complexity but the fact is that the mr freeze kit works with almost as impressive results for less money and a lot less complexity. Its probably like comparing carbs to efi. Why would you ask people about potential problems with a kit that you have, then listen to somebodys positive testamonial, and bash the kit you chose over and over with theory and comparisons to another more expensive and sophisticated kit ? I dont mind discussing the differences between the two, but for someone who bought the mr freeze, you seem to have nothing positive to say or even agree with. Why didn't you start a thread saying " Who agrees that the snow kit is way better then the mr freeze kit " Sorry if I sound peeved but I guess you were hoping to hear from a bunch of people who had problems to convince you to buy a snow kit instead. I recommend you sell the mr freeze and get the snow kit so you don't erode your impellers and blow your motor from poor atomization.

The mr freeze is only designed for centrfical superchargers and turbos, I believe that the snow kit does have the ability to be used on positive displacement blowers with the maf kit, if you use prochargergt's link you can read about it.

I'm not bashing it, I'm simply stating what they said on another mustang forum. I have your positive testimonial, and about 10 other's saying the Mr. Freeze will erode the impeller after time, and none of those people have rock solid evidence. So of course I'm going to bring YOU, the owner and person running the kit, all the criticism I'm facing in making the decision of which kit to get, so you understand where I am coming from. I told you what other people were saying about the kit, and wanted to know if you experienced any problems. You asked about the PSI that it sprays and I sent you the link to the kit and pump. No doubt the Freeze kit is great HP for $ but longevity is what I was concerned with. Ultimately I think the problem is nobody has run either kit long enough to see any problems yet. I don't see why your getting all upset. If you want to see the page I am talking about PM me and I'll be happy to share the link with you.

Sorry for getting upset. It sounded like you had already bought one so I was a bit confused why you posed that question and were so negative to everything I had to say about it. I understand that you were just relaying info you thought would be helpful, I guess I'm a little touchy about it because of how well its worked for me. I will definitely let people know in the months to come if I notice any problems with premature wear of any parts or inconsistant tune issues.

It's cool I am just notorious for having trouble with car stuff and I like to research heavily before I get stuff now. I actually got both the Snow kit and the Mr. Freeze kit on the way - I wanted to check both of them out and consult with a few local mustang guys around town, to see their take on both of the kits. I knew a few people, including you had one on the boards, and could give feedback on the Mr. Freeze kit as it is relatively new. My main concern is longevity, as I just dropped over 2K into the car because of a $5 part that broke (valve spring) and that thing was run for about 6 months with those springs...so the last thing I want to do is tear down the blower to replace the impeller in a year or two. Either way I'll have one of those kits on the car because next weekend I'm gonna get new dyno #'s, Jerry from SCT is coming to tune it. Wish me luck!!

Well if you don't have enough time to install the snow kit before next weekend, throw the freeze kit on there and check it out. Its so easy, you could put it on in a half hour and take it off just as easy to try the snow kit later. Im sure it wont hurt to have it on for a week or two. It would be cool to get a side by side comparison of the gains each made. I am very curious to see how much more power you can make with the adjustability of the snow kit. That is, if you have a good hookup for dyno time. That comparo would cost me 600+ bucks. Anyway good luck and I'll be keeping an eye out for the results.

I just finished my install of the Mr. Freeze kit and the dyno numbers amaze me WITHOUT A TUNE! I gained 30 HP and 27 Ft. Lbs. of torque. And now I am running rich with a 10.8 to 1 A/F. Now, to advance the timing a bit, lean it out and find out what the real gains are!! The installation was simple after you find a place to mount the reservoir. My intake air temps dropped over 60 degrees.

Ok so where did you mount it? I'm debating doing a vortech (9-12psi) a menathol injection, with a shot of n2o (you know just in case). Would the menathol injection be worth while at that low a boost pressure? Also has anyone used just windsheild washer fluid? I heard you can.

Well...if I ever get my car back I'll be running windshield washer fluid initially, then I might go to a 49% meth/51% water mix from snow performance
