AEM pump. The pump is fine just the thread sealant they use to screw in the push loc fittings needs to be replaced. Other than that no issues. The 100% meth scare is because of its flammable properties, not so much of the pump failing.

Yeah they had some sort of sealant that basically was just washing away from the Meth. I put regular teflon tape on and havent had any issues since.

Both have pros and cons, but I have to say water/meth has far less cons, it is so much more versatile. The one con to water/meth injection is it is one more thing that could fail, but are nullified if you choose to run fail safe measure (there are several ways to go there) Pros - Yes you can achieve equivalent octane as E85, you can in fact surpass it if you choose by the ratio to water you want to run and the size nozzle/nozzles you want to use to inject. Running on gas gives you much more efficient partial throttle running which is where you spend 95% of your driving, then you get all the benefits of E85/race fuel with the water/meth. The water % in the injection actually boost trq and removes heat better then any E85 or race fuel can depending on your calibration. You can get more then a 125-150 miles to a tank of gas, you dont have to worry about potential fuel system compromises and you dont have to deal with finding E85 stations. These are a few things off the top of my head.

thanks, i know there are multiple types of failsafes depending on what system you run. Also i read you can run the signal to your ems as a failsafe also, using one of the inputs like nitrous or something cant remember. Ill be running haltech or AEM when i finish getting all my parts in.

Yes this is how I have mine setup. If the controller signals an error, my ems retards timing by 15%.Its very simple. However If I was you I wouLD definately rather go with E85.
With the eth kit you just introducing further complications that can go wrong. My pipe blew out the back of my nozzle. Luckily I was running a 50/50 mix otherwise I would have most certainly burnt up my car cause its highly flammable. Also a hassle continuely filling the tank up.
Unfortunately we dont have E85 here otherwise that would be first choice. Water/meth works but its a hack to run and monitor and if something goes wrong it can be pretty bad esp if you dont have failsafes in place. My mate blew his K20 turbo on the track last month cause he didnt build in a failsafe and he ran out of meth.
You guys dont know how lucky you are to have E85.wE WOULD KILL FOR IT. So use it!

my power goal is 450-550. Currently have FIC 900's (flow like 1000cc) and a DW 300lph pump sitting around. I like the idea of having cooler combustion temps so id like to run either or. Ive read people running E85 on 1000cc inj and 300lph pump. Seems like the norm is a aero340 and 1600's. I have no plan on upgraded fuel lines and at the most i would run an AEM regulator. Curious to see some input on the best idea for my power goals. Thanks gurus

depending on the dyno, you will hit 450whp on pump gas. will be tough on base fuel pressure with e85 and 1000cc injectors.
stick with pump for now. when you are ready for a decent jump in power, go id2000, fb340 pump, stock base pressure and near 550-600whp on e85. not worth making it work with what you have right now imho.
