Just wanting to install a Water/Methanol Injection kit on my RB26 for the purposes of primarily reducing knock.

Only problem is I cant find any decent tuners here in Melbourne who supply a good kit and install/tune the setup.

Can anyone recommend a place?

ask trent at status tuning?

Not in Aus. but isnt BP Ulitimate 98???

In that case you should get a proper tune done instead of trying to reduce your knock levels by using water/meth injection.

Jst wanna say something about bp ultimate, it seems to be inconsistant in its quality as ive filled up twice now with it; the first time it performed well just like v-power that i had my car tuned on.

This second time, about a week ago i filled up with bp and the knocks are going up; not many by about 6-8 at 5000rpm or so

dont know anything about where the fuel comes from or wanna bad mouth anyone but jst giving my experience...im gonna buy a tank of race fuel from autobarn 20litres for 70bux and dilute the tank just to be safe.

it would be reasonable to expect some levels of variance in fuel octane

this would be regardless of what you buy, where you buy it from, and the brand etc

98 fuel is as you would expect, 98 fuel, sure there will be an occasional shit batch here and there

but i think some people really "lock" into a specific brand of 98, its just fuel ?

a knock of 6 to 8 is nothing

if your car is tuned properly it should knock consistently if you follow the oldschool "advance timing till it pings, then back off 2 deg"

so any variance in fuel, air temp etc is nothing to worry about

WMI comes up a fair bit, and a few of us are using it or intend using it, wondering if it wouldn't be a good idea to have a permanent thread on it????

Might answer a few questions before they are asked.

my thoughts too, but i dont know the exact setup. Cat asked me a similar question earlier today so i presume R33-RB26DETT it was from you. Feel free to pm or email me your full setup and car usage.

Thankyou paul, i did read your excellent faq for power fc.

My car was tuned very safely so the 6-8 knock aint gonna hurt anything, im jst one of those paranoid guys who goes overboard with his pride n joy.

Ive jst done a little test with octane booster which ill post in the FI section, see what people make of it.

I don't use anything but BP U98, has never burnt me. It's is refined over here in WA and I think you'll find that most of the other 98's are lesser grade fuels from BP with different additives (there was a big thread in the WA section about it). Shell might be a different story.

I don't see a problem with the guy wanting to run it to be a bit more safer. I've been thinking of doing the same thing when I track the car next year. The intake temp differences around the year we get up here are quite broad. During a summer day on a track i know i would want every precaution method taken.

Absolutely, your the type of person who takes care of his car n dosent want to take a risk even if the protection helps 5% n cost a few dollars....rather than the cheap bastards saying "it'll be right, she'll be right." your wasting your money; the bare minumum approach lolz

methanol injection for the track, nitrous for drag strip, dilution of race fuel or octane booster on a hot day etc

Im even thinking of meth injection in the future as long as the system is reliable.

BTW check out da thread i made on octane booster which i tested

I've been battling with this for some time now....

I am planning to get a pair of Garrett -9 which is the no. one priority at the moment, so money will be tied up there for sure!

My main prob is that i only have at best 95 available and i get knock with the stock ecu@12psi(not sure if 26 ecu has a low octane map), so its a toss up wether to get the water/meth and run it on the stock ecu or buy a pfc and get it tuned to suit the 95, running the -9s

Like u, i just want to be safe, hence the reason of changing the turbos in the first place! Not really aiming for huge rwkw numbers.

Ive done quite a bit of research on water/meth and its seems to be a definitely good "protection" measure especially in your case, as u would have less risk involved because u have the 98 to fall back on in case anything goes wrong with the system, ie. given that u don't tune extremly aggressive (lean mixtures and advanced timing).

Once u can afford it......give it a go :laugh:

I wish you all the best with your car mate, im treatign my car very well right now cos of those stocker ceramic turbos and will, like you be doing a -9 swap soon; not chasing big numbers (anything over 270awkw is good for me)

I hope you checked out my octane booster thread but it seems a good idea is to tune your car for 95oct on the power fc and buy some race fuel for a mix (like 30-50% ratio to pump fuel)

For WMI, i jst dont like an extra system which can fail if you know what i mean (pump failure, fogger failure, tank running dry etc) all these things bug me n i jst want a nice easy fix like the race fuel mix.

Im tryna find out whether you need a liscence to buy it, maybe give some thought to that idea?

ill of coase update you on anything i find out, n every1 else who likes to add safety to their cars.

cheers mate

I checked out that whole additive thing before i settled on the water/meth concept.

Toluene was my first option but just worked out to be far too expensive in the long run... so i could just imagine the cost of race fuel!!!

Well if every thing works out i'll be installing a Coolingmist kit next month, so i'll let u know how it goes.

lolz yeah the toulene mix was in my head before but had a few doubts about it eating away at fuel lines n other engine components due to me driving my car once a week (if that)

love to hear about your WMI, please post a thread up on it n maybe you might jst sway me in that direction.

Ive injected meth before, worked nicely.....whoops but thats a different story lolz

in your type of cases where fuel is a given issue (ie inconsistent) i would strongly reccomend running a remap of the std ecu, we have a few running high 300kw's on them without issues and the benefit is if you do get a batch of crap fuel the knock map will go a long way to saving your ass.

The main usage (but not always) for water meth is actually to get MORE agressive with the tuning, the issue is if the w/m stops working you are left with a fairly hairy issue. If your lucky and have an ecu with relevant GPO or GPI's you can set the warning on the WMI to switch to a low octane map.

Even if you use the system to stop your current knocking issues with water meth the underlying problem is still there if it ever fails to operate. Fix the underlying issue, or be vigilant with WM levels :)

either way the only sytems to use are available from rocket and here is the systems website. http://www.snowperformance.net/

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
