How much did this set you back?

You can get them from rocket or a seller has them on eBay. I think you are better of buying a 20l drum of methanol for $70 and buying distilled water form the supermarket which is $2 for 2 litres. Works out cheaper than paying for postage of the boost juice

Only one bend so all good, most people seem to start boost at 5 psi and have it all in at whatever max boost pressure they plan to run.

I am probably just gonna let Jez pick the sweet spot and see what things are doing low in the load points

For 8 x 1 gallon containers it was 110 bux. I know it's more expensive than mixing it yourself but methanol is VERY carcinogenic plus it's not as easy as going 1 litre of water and 1 litre of meth, you have to go by weight apparently. So I have read but this could be incorrect.

I'm lucky that my car isn't a daily and sees more track time than street driving lately so I'm not overly concerned about the price

Where abouts is this methanol for 20L do we have a supplier down here in ACT

Yeh man we have several, couple in fyshwick and queanbeyan

Didnt know about the by weight measuring, it shouldnt be to hard to work ou with basic chemistry anyway. As long as you mix in the same proportions everytime/ the same as you tuned with and as long as you mix it in a well vented area it should be fine really

Shouldn't matter whether you go by weight or volume. 50/50 volume split would be about 45/55 split by weight, so it's not a huge difference. What matters is that you use the same method every time, don't go by weight for one mixture and get it tuned, then decide to go by volume.

Exactly my thoughts, stick to the same mix all the way through and itll be fine

Yeah true, didn't think of it that way. I'm just a bit lazy I spose and rocket industries is only a 15-20min drive from work so no biggy for me.

If I find that I end up going through heaps of the stuff I'll look at mixing it myself.

I meant to post this earlier, a good read on how to tune for WMI

http://www.romraider.com/forum/viewtopic.php?f=33&t=8051

So going off that, they have to tune without the wmi running and get the target afr where the tuner is comfortable with. Then turn on the wmi, see how much the afr drops and lean it out/ add more timing (within safety limits of course) to get it back to the target afr.

Sounds logical to me. Might be worth getting them to save a copy of the non wmi tune and give it to you so you have a copy of a safe tune that you can run without having to worry about not boosting etc if something plays up on the kit. That is presuming the ecu doesnt have te ability to swap over maps Eg nistune and power fc

I have a pfc and fc data logit I'll get Jez to give me some maps.

So I suppose to start with I'll set it for something silly like start boost at 40psi and finish at 50 psi so it just won't come on and get Jez to start from there.

I have no idea when it comes to tuning so maybe someone who knows could chime in and let me know if that link makes things sound like a very time consuming exercise or not.

I assume it would be the same as getting a full tune with a new ecu.

@Titan, thanks for the info mate. When I spoke with coolingmist they suggested the large tank because I do track the car and even they said I will definately go through a lot of meth in these situations.

Has anyone found an intake air temp sensor that is methanol safe yet, do they exist?

I'm not sure it would make much difference even if you could put the IAT sensor after the WMI injector. The real temperature drop would occur when the WMI mixture changes state in the cylinder.

Would be a bitch trying to measure that! :P

on the track is a different story, expect the car to drink it in that scenario.

as its only on when you are on boost and around town thats never an issue as you cant be on boost for long periods, on a race track however most of the time you are out there you are trying to keep it on boost.

for a car thats street only, a small tank is great. the more track use it gets the bigger your tank should be or you will be filling it after every session.

Yeh not so concerned about trying to measure the temperature drop, but my IAT sensor is just before the throttle body. There's no way I could place a WMI injector so that the IAT sensor is out of the stream.

Ahh OK. So you are considering going down the WMI route too? :P

630 ml/min

with variable water meth controller

I think I will use the 625ml/min one that came with my kit. It's a is a bit more than what is recommended for the engine size, but considering the application I think it will be better than the next size down (375ml/min).

Good to hear someone else is going for a bigger nozzle, it has put my mind at ease a bit.

Running 315rwkw, I saw no difference between 375ml and 675ml nozzles, only a bottle that emptied twice as fast.

With the 375ml nozzle, I was able to max out my timing, and that was with a GT3076 and a 0.63 rear housing. If you have a 0.82 rear housing I'm sure that you won't see any gains with the bigger nozzle.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
