[Mk2] [Turbo] water/meth injection with an AEM system....info and questions???

Post by jimGTS »

ok, instead of going for some crazy priced CC system (i cant go st205, as got a top mount turbo), i want to go down the WI route.

tried and search, and found different opinions, some as far back as 2005/6 on this site....
wi kits have changed since then...

i have my eye on, the 1 gallon kit

WHY YOU WANT ONE

AEM’s Water / Methanol Injection Kit reduces air inlet temperatures and exhaust-gas temperatures, which allows you to increase boost pressure and advance timing without having to run higher-octane fuel. It’s like getting to run 100+


safetly
Critical safety features are integrated into the system to virtually eliminate any chance of failure, including an integral fluid level sensor in the reservoir, a dash light to warn of low fluid level or error codes (including short circuits, battery voltage and more), and an additional output to either decrease ignition timing or boost (like the sound of that) if the system detects low fluid levels or a system error.




Ryan at 2bar, has suggested a boot mount, or radtek for my setup to crack 400hp, simply to much work/money i feel....i mentioned WI and he had alot of positives to say about it!!!!!
so for ease of install and use, want to go down this road.....


what are peoples opinions on the above kit, and WI in general....
bar in mind, ill probably run 100% water first off, (so hopefully no need for a remap), then think about adding METH and getting mapped with it......to hopefully safely crack 400hp at low-ish boost.......

i like the idea of cooling intake temps, and basically cleaning the engine with the injection system. and when needs must, METH to help advance timing and hit some good numbers.

im currently around 360-370 at 1.4bar approx from ryan estimates when he mapped it the other week....

i always thought WI was a bit of a band aid but then did some digging on WWII aircraft and found a story on Frank Walker. it explained how he did the WI for the fighter engines and it made a whole lot more sense. Basically with WI you can reduce the amount of fuel being used ( you wont need any cooling effect from it thats the water), raise the boost and advance the ignition

Do a search on Frank Walker and you'll find loads of info, it's not just point and squirt

appreicate the fighter jet stuff, but unfortunatly i drive an mr2, (gutting, pmsl)....
so would make more sense to here of pros and cons using this with a sidemount......

in my search, i saw you fitted one? hows that all going???? getting the results you want? in terms of cooling and safety?

thanks

ya daftie ! WWII piston engined fighters lol (mostly) Hulking great big radial engines and of of course the best sounding engine ever made, The Merlin V12. Using water alone allowed more boost and less fuel to make more power but then they had to add Antifreeze to allow it to work at 10k+ft altitude. Using the Water / Methanol mix allowed even more boost because the knock threshold increased hugely. I believe using this system was called WEP = War Emergency Power basically everything the engine had to offer, max boost, max power and er max reliability. Breaking down wasn't an option (though the engine strip down checks were regular)

I fitted the 205 chargecooler but alas I had a leak in the pipework system and killed the water pump. Never have got round to refitting it, still running the std side mount.

:?

am sure itll go well, if not am sure i can easily sell it, considering the lack of UK suplliers....

no more suggestions on this??

heard i really need to get mapped on the water/meth, as any water, or meth is just going to alter my AFR, in effect we lower the hp!
but give me nice cold temps.

a cheap kit will only sap power imo. yeah it'll reduce intake temps too. One nozzle, one flow rate for various RPM/TPS positions isn't ideal. Best thing I've seen is the coolingmist variable controller.

The more you spend, the better it will be.

ive bought the AEM unit, one of the best and most expensive units....
has a progressive controller based on boost.
and multipal warning features.

because there kits have 100s options, 100s versions, 100s of extras etc etc....

i wanted something that had everything in one kit, without the need and hassle and expense of getting extras....the kit has virtually everything you need.
plus the aem one is tried and tested and producing excellent results over in the US where its used more on the mr2 than over here, so i went for that instead...how many on this or similar uk forums are using WI on there mr2s? not many, if any. so i went with something i had seen alot of evidence and data on, which was the aem kit over in the US.
over there its considered one of, if not the best WI kit.

plus for what you get for the money, and importing it from the US, i got it for a very good price compared to anything in the UK.

How much did you get it for?
TOTB 2010 Rwd top speed, 1/4 and shootout winner.
10.7@142 on R888 street tyres, 10.3@134mph on slicks,
9's on slicks to come, with a clean full throttle pass! Goal of 0-150mph in a 1/4 of a mile....

i got one with custom support brackets for the tank for £250 insured/tracked and delivered from US........delivery cost me $70 alone.
i could have got it sent for $25 to save myself more but i wanted it insured and tracked.

which i dont think is to bad really. but a saving is a saving i guess.

i thought the metanol was to stop the lines and jet's from rusting?

i run the spearco water/methanol injection kit, make shore when you add the water you used deironised as water in our area mate is chalking and blocked my first spray jet i had.the methanol i used to get from r/c model shops it used to be £6.00 a gallon. mix it 50/50. i would not map the car with this running,map the car then use it as a back up you will smell it in the exhaust when running it. i will be refitting mine when the engine goes back in.. warning if methanol catches alight you will not see it burning(it burns clear)

r/c stuff has oil in it tho.
i checked out all the rc shops, and they all have 5-15% oil in the fuel.......

if i dont map with it, surely im just going to run way rich....

no that is nitro methanol mate that is different that is what i use in my hpi drift car & the number rating is the oil content the less the oil the faster your car goes.. put that in a moped once the think went like stink for approx 5min until it dried all the oil from the engine seized solid it was fun while it lasted lol. where did you go to get it jim? if you map the car with it running & you run out and dont realise the intake could run a lot hotter as when you mapped the car you were relying on the cooling affect of water/methanol

I have nothing but praise for my cheap Devils Own W/M kit, OK it’s a track day car and never been registered for the road over here but it’s a Rev. 3 will 11 hard OPL track days with two drivers under its belt, still on standard internals with a Street Brawler turbo kit (1.4 BAR) and Ebay intercooler, Lyndon mapped it at 310 WHP.

I don’t expect there is any extra power perhaps a little less the only thing I have noticed since fitting the kit is after the cooling down lap and letting it tick over for a minute or two before
the heat in the block would boil the water pushing it out the overflow and now it doesn’t, so to me this points to less lightly hood of cracking the block, melting a piston or blowing the HG

Model Technics do straight Meth.
