Lets talk Meth

[hoosain]

Guys meth got very interesting for me:

(Density = weight divided by volume)
Water is 1000kg per cubic meter
1l water = 1kg

Meth is 786.6kg per cubic meter
1l meth = 0.7866kg. (0.79kg)

So if I understand this right.....meth evaporates faster than water right? I think at 80 degree Celsius? So in essence it has a lower evaporation level than water.

So what I did wrong...2.5l water & 2.5l methanol does not give 50/50 mix. (Like Burgy mentioned earlier)

Lets say for arguments sake my bottle holds 5liter in total:
Would I need to mix 3l meth and 2l water
or 2.8l meth and 2.2l water to make it a 50/50 ratio mix?

Because I can't seem to work it out from here :bangdesk:

rommies dont stress such a lot use 2.8l or 3l meth with 2.2l and 2l water respectively ratio will be fine

lol! Thx! Will try it out and see how the car reacts.

It seems to me this whole mixing thing works on weight, rather than volume.
The weight of the fluids must be similar even though the volumes may differ.

Hmmm interesting!! :=):

Hey guys,

So a bit of a revival on this thread, I have been around the block twice with getting a reliable working set up and thought I would share my experiences,

So initially after getting a tank from Rennzport and installing the lines and wiring, I could not get the fsb to communicate to the JB4, the system wouldn't prime and it was a huge anticlimax to me, so I pulled the fsb controller and put it aside and rehashed the system with a simple boost switch (Hobbs switch). I took switched 12v power and supplied it to the Hobbs switch via a 10amp fuse, the Hobbs switch was tapped into the little pipe that feeds the DV's as this pipe carries both vacuum when the throttle is closed and boost when open to keep the dvs from leaking, the switch is set to close at a default 10psi but can be adjusted higher if needed, however when it's closed that's it, there is no variation or progressive nature to this simple controller. The output from the switch when activated carries power to the positive on the pump and one of the wires on the solenoid. The remaining solenoid wire was grounded to in the engine bay and the tank was grounded in the boot area. I am happy to report that for a simple no frills no fuss system this method is both reliable and fuss free...

However the drawback to this system is that I didn't have use of map 3 on the jb4 which is a methanol map that raises boost as a function of meth flow. :blueCry: so it was back to the drawing board for me to figure out why I didn't get it right the first time with the FSB, upon closer inspection 1 of the dsub pins on the fsb wasn't making proper connection, it also seems in my anxiety to make this work got the better of me, so with the connections redone and a continuity test confirming that, I plugged the fsb back into the jb and connected as per BMS instructions, this was with switched power coming into the FSB, ground output going to the shock tower, the 2 dsub pins inserted into the jb4 harness in their slots, the output power routing to the fuse and then supplying both the pump and one solenoid wire. The remaining solenoid wire now connects to the last remaining green wire coming from the fsb. The jb now has independent control of the solenoid and the pump.

The system primed on first try and worked as expected. Map 3 with a 55 boost additive was crazy and a 65 boost additive was absolutely Insane!

The latest meth failsafes available from BMS allowed me to set the meth to activate on all maps, (something I prefer) with spray beginning at 10psi and reaching 100% spray at around 14psi...

So far I am chuffed with the system and latest logs are very smooth with no cause for concern. I do have a few ideas in mind in future but I will leave that to another day to discuss...

Thanks to everyone who supported and provided advice for this...

:clapper:

For anyone curious to know, the set up is:
Coolingmist tank with on tank pump mount.
Coolingmist pump
Coolingmist solenoid
Cm10 injector x 1
BMS Fsb controller
Using a stett meth elbow as spray point

Well done! Any pics of the setup Kish?

Great stuff Kish :thumbs:

Speaking of meth, I think Heisenberg is running an operation this side! lol

This post is useless without a dyno :clapper:

Congrats, the meth is a game changer. The FSB works very well and the new coolingmist fittings are leak proof so top choices in hardware. On a side note spin the tank around now and then and feel in the back for leaks at the piece that exits the tank, if it drips it pools.
