Hello,


Im currently stockpiling parts for a BBT Hybrid Build.
So far I have an exhaust manifold and rods and welly cooler.
Next on my list of things to buy is a WMI kit. Following Bills advice I want to go for a devils own kit. I just want to make sure I have the correct bits.

Methanol Injection : Alcohol Injection : Water Injection : DevilsOwn

Methanol Injection : Alcohol Injection : Water Injection : DevilsOwn

Also, where do people buy pre mix from? I know devils own do their own but im sure I read a threat stating that VW quantum screenwash is the same thing, I just happen to work in a VW dealership and can get hold of this for pennies




Is that the stuff?


Thanks for any help.

Paul
 
Very interested in this thread as considering WMI setup as-well. Will be keeping an eye on the replies. Im only a BBT and manifold away from the same spec as you, have recently done my rods. What sort of figures are you after?

Not as effective as real 50/50 water meth from my experience... real 50/50 will reduce CF further than this screenwash used neat by another 3-4CF from what I've seen and logged
 
Thanks Bill. I've found methanol on eBay etc so it's readily available.
How much would you charge to fit the WMI and carry out mapping of the BBT? I'm nearly there!
 
Ring him up tomorrow, tell him your spec and the desired results and he'll probably give you some prices then.

He's ****** good. But he doesn't have a crystal ball :(

I wish he did...

if you are getting the WMI kit, like the DO kit on my car, make sure you get the progressive controller, as this is great. has 3 lights on it, one for power, one flashes to tell you the pump is working (which I can hear anyway as my car is stripped out, but if it's not then its worth while) and it will flash when your meth is getting low as well

I have sat many times boosting a long then seen it flashing low, so stayed off the boost on the way home. I didn't mess about with the settings too much, but it's good to see the kit is working up front when you're driving.

this one:

no worries

it of course adds a chunk of cost to the package, but is easily justified as it gives you peace of mind the kit is working and you have plenty of meth in the tank
 
basic pressure switch kit works well imho

watch the actual spray pattern from progressive controllers to see why On full is actually a nice simple but very effective way of delivery the fine mist you want from a wmi kit

progressive controllers are fine, when they're working

not a good history of reliability on most makes I experienced which is why I have reverted to KISS approach
 
Controllers are just more to go wrong, what's wrong with checking the level of your meth?

My AEM controller is most broken...

can you check the level of your meth when driving, or are you able to check the unit is powered and the pump is working when on boost/driving?

not tried driving on a motorway/road at full boost and crawling into my boot at the same time, could be dangerous
 
Nothing wrong with checking it before you leave, no different to checking your oil.

It's more from a simplicity and replacement point of view.

A devils own controller is £130+. And it WILL break one day.

Or you buy a pressure switch for £25, an LED for £1, a level sensor for £20, a bit of wire and some know how and you can have something much more reliable for a third of the price.

My LED (when it worked) lit up on boost, flashed when low. Was off when the pressure was lower than the controller was set at.

Just need to replace the controller with a switch, and rewire the existing level sensor to a relay.
 
What happens if your car is mapped with meth and you run out?

Level sensors handy, but not full proof. Seen several floats stick up indicating its not empty when it was, so not fool proof either, nor is there any proof of actual spraying happening, as at best all you see it it *should* be powering the pump, whether anything sprays out of the nozzle is'nt a given.

watch the function of slow start on progressive and come back when you've seen it vs full.
Much nicers atomisation when the pumps allowed to spray at its full psi

All imho, but what do I know

Theory is that EGT's will rise and protection will kick in limiting boost and dumping fuel.

If your car was mapped by somebody sensible.

Worst case, things melt and expand and go bang.
 
I don;t have any lights. Nothing for low level, nothing for pump being on. I do have a liquid gauge so I can easily see intake and exhaust temps.
I check my meth when I fill up with fuel. Never managed to run out yet and I have a tiny wee two litre tank

it runs warmer and will pull more timing BUT how its mapped is important to the outcome.

eg.. A dyno day here a couple or more years ago.. an LCR with wmi "max'd" out by the owners mapper, wmi had failed, it pulled maximum CF on the dyno when I was logging it so I aborted it at that point, and the car apparently went wrong, blew up or failed in some way I dont remember on the way home. Tune to the "max" and this is always a risk. << It does'nt have to be tuned irresponsibly like this, but this example it was balls to the wall tuning... Each to their own. Not something I condone.

not all cars have egt..

AITs will be the initial tell tale as to wmi not spraying
 
I think il pass on the controller if they are rebound to break, and use the money towards the clutch / turbo / mapping etc
Roll on pay day !
 
So which DO kit is the one to go for then? The universal 6-30 psi?

I think what you say is true,although the AEM controller on mine has been more fortunate,and has run fault-free for 3 yrs now.

(WHich has probably jinxed it now...)

As Badger5 says,mapping for WMI is all very well,but for those that push the timing to the limits,if the WMI fails,it's looking for trouble.
 
reading up on DO kits, it seems the more older generation controllers use to break, but the newer ones are much more reliable (I've jinxed it now!).

I've bought my Devils own kit it should arrive this week.
Do most people mount the nozzle on the post intercooler boost pipe ?
I run the "welly cooler"
I've also seen a throttle body spacer kit on eBay that envorporates a WMI nozzle point. Would this be any good ?
 
Up to you, some people mount them in the coldside IC pipe, some people mount it in the silicone hoses going from the cold side IC pipe to the TB, some people mount it in a TB sandwich plate.

Whatever one is easiest for you, but ideally you want the meth to have long enough to disperse and not so long it loses it's potency.
 
Just been bidding on a kit on ebay for the fun of it the kit you are on about 6-30psi full kit brand new went for 84 pound. Probably should have brought it but didn't know if it was worth it so stopped bidding

Cheers Jardo.
Where is yours mounted?
I guess it would be easier to use a throttle body spacer but I want it to do its thing, so after the intercooler sounds the best
 
Mine is mounted between the IC and the TB.

Doesn't work though haha.

Not exactly no... alloy pipework is not thick enough so you will need to weld on a boss or build up enough alloy weld and flat it off to get enough thread to prevent mechanical failure

Or get you and Bill to fit it when it comes down for mapping ? ha ha
