Water/methanol Injection Rb26

[Don Dada]

Well i'm interested to know what experience you guys have had using water/meth injection in terms of brand of kit,problems encountered and overall performance.

In my country our highest grade is 95 and the weather is constantly hot (30-35*) so i cant enjoy the true potential the 26 has to offer.

I had a safc2 lying around so just out of curiosity i hooked it up using ONLY the knock feature to see what was going on.

It didn't surprise me at all to see i was getting knock,and very high levels too- around 185.

I know the safc2 is not the best when it comes to knock detection, but it works... When i had it on my 25det, with no correction, i could hammer the life out of it and get no high readings, but when i started to take out fuel and the ign advanced i was able to see high spikes an sometimes even hear detonation.

Anyway back to the problem at hand...

I have since retarded the timing via the cas to 15* and on 12psi at around 3500-4000rpm when boost comes on full, and also close to redline, knock reading spikes, on a hot day. (stock ecu/turbos)

The thought of using toluene crossed my mind but it is not economical in the long run, so my best and only option really is water/meth injection.

I have also thought about using a pfc, but in essence, i would have to actually de-tune the car to get rid of high knock levels using the 95 shit so it does not make sense.

I have seen "the mafia" had good results using water/meth injection, but haven't seen him around in a while, so can others pls share your experiences preferably using it on the 26

My plan is to get it in order so i can safely run 14psi and return my timing to 20* or even a little more via the cas, to get some extra power using the water/meth injection.

I'm looking at the AEM kit (pn 30-3000) . What do u guys think?

Thanks.

An extremely good reference for water injection (worth while spending time reading the immense amount of information):

http://www.riceracing.com.au/water-injection.htm

Great kits also. Proven performance and reliability on a fragile engine on pump fuel (rotary), also plenty of RBs running 140+mph on street tyres and pump fuel with this kit and tuning advice, many of these kits make their way overseas.

Can you run water/meth injection with nos..?

[Don Dada]

come on guys.... i really need your opinion.

[GT-R32]

A properly set up and tuned for Water Injection system would be perfect for you. I've seen rotaries run on 91 fuel at 20+psi boost. Water cools the engine combustion internally - where it matters.

Can you run water/meth injection with nos..?

Yep, WARLORD is running nitrous and water/meth on his.

[Don Dada]

Well i've made up my mind on getting the water/meth kit....the problem now is WHICH ONE?!?

I still need ur guys experience as to wether using a progressive kit that uses boost pressure or a kit that uses a 0-5v signal via the MAF.

I'm checking out the Coolingmist kit that uses either boost or a 0-5V signal, or a combination of both.

I guess with this kit i have the option of sticking to which ever method works best, but this kit is hell expensive!

Thanks again guys.

[Don Dada]

Lucky bastards!!!

I'm sure not everyone has 98 to run on their skylines.!!!

Help pls.

[Rezlo]

I presume your from RSA, why dont you run DevilsOwn kits like most of us do?

[stricnynel0s]

AEM uses a progressive boost dependent sensor for their meth kit honestly its a decent looking kit, but i also want the zex turbo nitrous kit too hahaha in the us we can get 93 and sometimes 94 at the pump

Snow Performance in the USA has some nice kits. Computer controlled. Google it!

[WHITER33GTS-T]

Im looking at one of these kits from Snow performance.

Water Methanol Injection Gas Stg 3 MPG-MAX Boost Cooler

The MPG MAX® Stage 3 Boost Cooler® is unmatched for increases in Fuel Economy AND Power in water-methanol injection systems. Key to this is accuracy and adjustability designed into the system. This Boost Cooler® can be used on ANY EFI engine (naturally aspirated or forced induction) and any forced induction application (EFI or Carbed).

In the lighter load states, it can read and inject according to either EFI Fuel Injector Pulse-width or Boost level, or any combination of BOTH! This allows it to be extremely accurate when injecting smaller amounts to prevent quench.

Additionally, the MPG MAX® Has the software and hardware capable to inject the correct amounts under the higher load states for serious increases in power.

Very easy to set up and dial in - the software creates a 3 dimensional delivery map from just a few easy to set start and full points you punch in.

The LCD Screen displays boost pressure, Injector Pulse width %, as well as water-methanol injection percent. Quick, easy, positive adjustments are made with 2 push buttons. Low profile design allows for easy-to-view and discrete mounting.

Kit includes:

• 150+ PSI High Volume Pump

• 3 Quart Reservoir

• LCD Screen, Pushbutton Digital Variable 3D Mapping Controller

• 3 Nozzles To Cover a Wide Range of Horsepower

• 10 feet High Pressure Tubing (1200psi burst)

• Flow Control Solenoid

• Dual Nozzle upgrade included

• All Required Hardware Needed For Installation

• Comprehensive Instructions

What are other people using..?

nick (warlord) has a nice kit which ive seen - ive sent him this link so if he doesn't respond, brand him as a lazy farker HAHA

[WHITER33GTS-T]

Cool thanks. Thinking about swapping over from nos to a water/ meth kit

[Don Dada]

i have a coolingmist trunk kit easy to install ive got the progressive controller that runs a 5v signal from my tps,so i can start it at one point with low spray up to full spray at just over half throttle im running a 12 gph injector but will be uping that soon.

Have u tried a 5V signal from the MAF? .... ie. if u run a MAF

Is this the kit that allows u to use a 5V signal or boost, or a combination of both?

[Marko R1]

nick, im not to be pursuaded by other peoples opinions anymore...u might be a nice guy afterall (bar being an 'ella re' which u cant help)

first of all your a prick marko answer your phone........... stop the poosti porn its not good for you..hahahah

now ill read the thread and answer

ok ive read

things ive learnt

get the 250 psi pump cos the 150psi pulses up hi and the 250psi will flow better.

buy the DevilsOwn injectors cos there is a fix nut in the middle which makes it easyer to take it of the bung as mine got stuck ands its a nflamin mongrel to take off.

I added extra boost and no problem at all 21-24.5,

As for nos they are two peas in a pod,in the states in most cases the run both in ozy ive never seen it or heard about it.they say you can use up to 250 hp of nos with out taking timing out but i would'nt im uesing 75hp but will be going to 125hp soon.

Don't run it in front of the turbo if you do good luck i would not.

Run it about 6-8 inches from the throttle body or for a rb26 just in front of the plenum.

You can tune for it if you want but i use mine for safty reasons with nos.

6L take lasts me about 800km or 200ks a week driving hard.

You will know if the pump or injector is to big or turned up to high if your car bogs down.

if you guys want pics ill post some,now these are my thinks ive learnt.

marko hows the rb26 in your sigma !! pick your phone up ......

no i have not tried the maf as for me the tps is the go!!!

mine was vaccum or 5v or both

[paulr33]

speak to "the mafia" he runs water meth injection on his RB25 in cairns with gt3X and has had great results and experience from it

he did some howto' / results threads, so search in forced induction by his username and you should his details, posts etc

[tridentt150v]

Give me a month and I'll fit my SP SIII Boost Cooler kit up and tell you how it is........I've got the kit, but I'm waiting on some time off work [working 7 days a week atm] and a set of gauges before I remove the inner gaurd and push it all through the firewall. Once I've fitted it, I'll tune it and see what I've got, but expect around 300+. Gtst with 3076 WG and pretty much all the supporting bolt on mods - can't get motivated to tear dwn a perfectly good engine just yet, so except for Tomei sticks its untouched.

PS don't hold your breath though, took me 8 months to fit up a SK Billie kit and swaybars etc, I'm slow, wouldn't want to get paid by the hour for any mechanical stuff atm..........lol
