I'm personally not a fan of W/M at all. I ran it for a year on my car and it was always causing problems. Getting the right jetting, methanol blend, and tuning just isn't worth it to add another complexity to a system already fragile as glass. I assume you don't have access to E85 where you are? I started running it on the Evo this season, and its like liquid cocaine. I'll never go back to 93 again.

I think if I go any higher I'll fit the cooling mist system i have and run a smallish nozzle.
No E85 around here .

no e85 here either. I was perusing w/m threads on 8club and it seems like the smaller nozzle works best. I would probably get with Kane for further help there. I recall a thread where he tuned a car running w/m

Have you seen what Rotaman did ?Think he did a thread - Looks pretty good .

Only see 3deg C rise on a 3rd gear log and 6C on a 4th gear log (5th on stock g/box). So for short bursts i'm pretty well sorted . Heat soak on the track will be a different story though.
#659
another added benefit to w/m is the cooling capabilities...could be a win win with adding that to your set-up
#660
does it log both pre and post turbo iat?

Team, the setup I'm using for my intercooler sprayer has been tested to be one of the best setups on the market.
It is not designed to produce lots of water hitting the IC, but a very fine mist.
The pump is rated at 200psi and easily covers the whole IC with just the two nozzles.
The airflow into the intercooler is what makes it efficient, the air pushes the mist into the intercooler. It does not rely on the nozzles to direct the mist into the IC.
For this setup to work at its best you would really have the nozzle in the middle of the intercooler pointing out to the front of the car, not pointing at the IC.
If anyone is actually interested in this type of setup, then here is a link to where I got the info from.

Sorry if you see it as a slam or something. The engineer in me just looks at it and says it could be improved on is all. ![Dunno](https://www.rx8club.com/images/smilies/dunno.gif)
What do you think that air at 60+ mph is doing to a mist being applied at the far ends of a wide intercooler? I'm willing to bet that it won't look anything like your static vehicle video and it is instead only misting those far end surfaces best case.
My suggestion helps to ensure misting across the full width of the intercooler rather than assuming it gets there from the end. Maybe get a GoPro camera and make a vid at speed to see for yourself? If I'm wrong it won't hurt my feelings or anything. I'll just be surprised is all.

No problem Team, I wasn't taking it personally.
I'm sure you are right and maybe with some more testing, it could be improved on.
This was the first setup of this that I'm trying.
I will see how it goes over the summer months and maybe try a couple of other combinations, and see what works the best.
The idea of using a camera to check it out sounds like a good move.
Thanks

Fitted water injection yesterday.
Using windscreen reservoir for tank and T'd off the outlet of the washer pump .... there is no leakage from nozzle when I turn on the windscreen washer .
Found a great place to mount the pump.
Nozzle is 200ccs on min pressure and 300 on max . I have it set around 200ccs/min
Did some back to back runs in each direction on same stretch of road, first with WI then without.
Fisrt chart is a log of speed vs time which shows a slight decrease in performance with water(no meth) . Blue vertical line is approx. switch on point (12psi). Boost is 14-15psi from 4500 on up.

Second chart is EGT . WI log run starts from a lower point and is trending towards the same finishing point . Kinda looks like EGT is not really affected by WI at this level . I really need a log where egt starts from same point to get a better picture though.

when you going to add the meth?

Slightly lower exhaust temps IMO is a huge win plus the added bonus of getting some water in there to reduce carbon build up.
However I do find the result a bit odd.
Same boost
Same maf g/s
Air displacing water
A bit more power?
Can the WI really lower the IAT and increase the air mass density that much?
Anyways, I'm glad you're messing around with this and posting results/findings.
I'm seriously considering putting the NO2 back on with a small 25 or 35 shot.
(Technically it's still on there, I just have to put the tank back in the trunk, install the NO2 control actuator and put the BHR TB spacer in line)
edit:
Ah you posted ahead of me ... lol oh well some questions already answered

So are these results about what you expected?

Well ... I was hoping for no performance reduction and reduced EGTs . I don't remember ever seeing anyone try this at an elevated boost level (and posting the findings) so thought it worth experimenting with.
Can't really say the EGTs are lower as the WI run started from a lower EGT and it is catching up. It looks to me like EGTs will end up about the same either way - more testing needed though.
Nitrous ? Do eeeeeeeeeeeeeeeeeeeeeeeeeeeeeet !
