Default Water Methanol Injection - Share experience

Hi all,


I have been considering if WMI is worth it or not, and having read plenty threads on here, albeit most are old now, it would seem it has plenty positives and very few negatives.


However I am keen to listen to new reports on how people are getting on, surely this has got to be better than running 20% meth in tank permanently like I have done in the past?


Seems kits have come down in price now, and installation is not all that difficult, plus I believe mapping this in is also relatively straight forward especially if a defined switch, i.e. 1 bar is used consistently (read this somewhere)


Thoughts people?


Robert

For the best results use both,

Great series to watch if your interested in gains from fuels.

Intank doesn't help with IAT

WMI would help with IAT

And for those who CBA watching 14 diff vids for seperate results

Here is the last one where all are tested with spray,

All data on the excel sheet if you make a tactical pause 1:28

This is on an NA engine tho bear in mind

Cheers mate, just watched the short clip.


For comparison of where I am at, I managed 401 from a stock 2004 STI engine with a SC42 I think it was, and remap with Meth-in-tank it made 432 (I remember these figures vividly) Interestingly though if I recall correctly it made only 350ftlb on Vpower, but almost 400ftlb on meth which is the massive statement. Almost 15% more torque.


Now the only thing I am not clear about is whether the car was mapped to its safe limit without meth, and then pushed harder on the meth which wouldn't offer a true back to back test.


However my dribble is irrelevant as I am keen to learn about Meth Injection


Thanks for posting the links


Robert.

Have It years its not mapped in just used at high boost to combat det at high ambient temps. Very useful if you've been sitting in traffic and everything's heat soaked. Every little helps and you can see the air charge temperature benefits instantly on the toucan when it kicks in.

Found them on Photobucket of the comparison of the 20% meth mix.... (great memory...)

I also got a huge chunk more torque from AF road dyno usually close enough ive found within 5%(ish)


A good video explaining why you get this torque increase,

It's all about the timing with Ethanol,

Can only tune till the point of knock on pump fuel ,

With E85 you can add alot more,

If you go on NASIOC they had/ have a section for W.M.I. and Aquamist (UK) frequently used to give help and advice on the forum. It just seems to have died off recently, I don't know why but there must be some historic stuff still there.
I have a Perrin/ Aquamist kit which was installed by Paul Blamire, (ZEN) in 2008, so 60k and has never blinked. It's mainly Aquamist but think Perrin may have supplied a few brackets and labels and it was sold through them.
The kit then cost 700 (inc vat) +spec c boot mounted water tank +9hrs labour (fitting) and of course initial mapping. That done it becomes part of the car and any further mapping is as it would normally be.
The pump and controller are mounted in the inner nearside front wing, the single jet is plumbed in the underside intercooler at t/b. It has a simple in car control switch which has warning lights for low/tank, low flow i.e. blocked jet (never happened). As said it's all mapped in and comes in at around 1bar boost. If it isn't switched on or there is a problem i.e. low flow, it limits boost to 1 bar.
It is a basic system, I think some are plumbed into the manifold for each cylinder. W/M is more popular where fuel quality is an issue. UK we have Vpower and added meth gets good power and safety.
The main reason I did it was I wanted to keep my TMIC, a personal choice.
Power wise we think it gives another 25hp, I have also run 20% meth in fuel and got another 25hp. Present figures on Vpower are 440hp/ 490lbsft (2.5/wrx heads) MD321T, so respectable. Charge temps/ oil temps/ egt's all on the low side and that would sustain on track, how much I can attribute to W/M overall is difficult but must be a factor.
Would I do it again? I would have to be quite convinced that I needed it because of the outlay, there are cheaper effective systems than Aquamist but when I did it I didn't need much convincing about anything concerning the scooby
