Been running the meth for a while now. Unfortunately didn't really need it it turns out. Advancing timing more didn't gain any hp.

The water meth is great for super low iat's though. 95 degrees out and iat's were showing as 65-70 with the water/meth. No such thing as heat soak now.

I made 422whp with the meth setup and 14.5 psi.

 

yeah I see similar results with mine just there to keep it safe under long spirited drives. I didn't really see much power change I run the middle injector. I have run the large injector and it does make a difference but the amount of meth I go through is crazy on a 120 mile group drive I went through nearly 2 gallons of 50/50 mix I make myself been running it on an s2000 almost 4 years with no trouble I used the washer fluid reservoir and mounted the pump under it wheel well keeps is safe.

 

Good info here thx guys..... Do you guys think i will make power with my set up? Im stuck with 91 octane....

CT 1200 kit
3.6 or 3.8 dont remember (11.5)
aftercooled


Only making 360whp on Mikes dyno down at Autowave (ton of timing taken out)



....My goal was to make over 400 with this car!

 

You should make 400whp with the meth kit same boost pressure. Get the timing up to proper/nominal levels. 11.5psi is enough to hit 400whp with the 1200 as long as the engine is running well with good compression and no Cat and a low IAT. Run the large 550cc meth injector and a stronger % of meth to water, like 60/40. Run a pump that delivers high pressure 200psi+

 

Sounds good... now i just have to decide if i want to put it in the trunk or hide it behind the fender! Think i can just pull the wheel liner out to do it? My carbon fiber fenders I dont think will like being pulled off and put back on

No, put it in the trunk. You will hate your life putting the tank in a place you cant easily access it. You need to be able to have enough room for at least a 1 gal, be able to access the pump and fittings for when they leak. You need to be able to visually verify your tank level for fill ups etc. Any number of reasons why the trunk is so much better. Remove the trunk tools and Styrofoam tray if you haven't already, mount the pump in bottom of the Styrofoam tray and the tank above this, mounting to the back/face of trunk liner. The tank will be partly bellow the trunk line and above it. You can take the lid and cut an area out from it to fit around the tank. I also drilled several 1/2 holes above where the pump was placed to allow heat from the pump to escape. Over the years of trying different placement configs and set ups, this is what i ended up with that seemed to be the most practical and functional. I could still use my trunk so that was good, however some small space is compromised with tank. Also have to be careful to protect the meth equipment and what ever else you decide to put in the trunk. You dont want to damage anything. Always some amount of compromise, because racecar.

 

i upgraded my lines and used the level indicator on the stock resivor with a devils own bung on bottom. 5 years with no problems at all used good lines and keep em short response is fast and carry a spare gallon in the trunk if your driving hard top off with fuel stop or the green light starts flashing. nothing wrong with trunk mount just set pressure at 0psi to make up for delay

 

Firstly great read.

Im in the process of fitting the AEM kit to my HKS supercharged S2000 running about 10psi. The main reason i want to fit it is to help keep the inlet temperatures in check whilst on track. My plan was to only inject water as my 800cc injectors are more than enough for 380bhp. I want the benefit of lower IAT and reduce the lose of power felt on a hot day.

What size nozzle do you guys use? i was thinking the 500cc nozzle and set the controller to come on at 2psi and to be fully on by 10psi.

On a side note the reason for fitting this is that my brother had an aquamist kit on his supercharged mini cooper s and it made silly power and would take a hammering on track and never missed a beat. The charge temperatures dropped massively.

 

The kit is pretty much fitted now bar connecting a boost pipe to the AEM controller and finalising the place to mount the water injector.

I tried fitting it in a bung already fitted to the intercooler but it staggers the injector too far off so most of the misting doesn't go into the intercooler pipework it just hits the side of the bung. I sealed this up and then drilled the intercooler pipework but its so thin its nigh on impossible to get the tap to put a good enough thread into the pipe.

Ive decided to leave it for now and then get some cheap aluminium brazing sticks to build up the thickness of the pipework and then try retapping it.

 

I welded a bung on the charge pipe to keep things sealed and the stock res holds a gallon with the pump under it there is gravity helping feed the pump and my charge line is 5 feet long. i have run 100% meth in the tank with no ill effect due to the res being out of the engine bay. As long as the fender liner is in good shape and you use good lines you wont be messing with the pump. If you loose prime you can take the jet apart hit the purge button to clear the air then reassemble. I use an a/c o ring to seal the jet to the bung so i don't destroy the plastic washer
