Hi Rob,
Yep we are the sole uk distributer :)
Which kit was you looking at?
Luke
Stage 2 kit. With a rear mounted tank I'd need the upgraded solenoid yes?

yep you would. I will sort out some prices for you.
Cheers, if you want to email me my addres is: blueleon@sky.com

Hi Rob,
The price for a Stage 2 Snow Performance Boost Cooler kit is £303.40 inc VAT.
This kit doesn’t come with a bottle as it’s made to utilise your standard washer bottle. However,
If you’d like to mount a reservoir in the rear i can supply a 2.5 gallon one for £41.10 and a solenoid at £34.26, both including VAT.
This totals £378.76 inc VAT, plus £13 delivery. £391.78 inc VAT delivered.
Thanks
My washer bottle is in the boot which I was going to use, so that's fine, so I'd need the stage 2 kit plus the upgraded solenoid - so would that be £337.66 + £13 delivery then?
Can you supply methanol too? Or a 50/50 mix (49/51)?
Luke, can you supply nozzles?

DJP: We can supply nozzles and have a selection in stock.
Rob: That's correct. We can supply ready mixed, but if im honest, it'd be cheaper to get some methanol from a supplier and mix yourself.
Cheers
Kev
What size nozzles come in the kit? How much is the ready mixed from you?

Nozzles supplied are dependant on spec and horsepower of the vehicle it's being installed on which we usually advise of before shipping the kit.
I'll have to get back to you on the price of ready mixed..
Cheers
Kev
OK cool. I have to wait until I've sold my sump, once that's gone I'll have the funds to buy the kit.
Just wondering, what's the difference between the MAF and MAP controller, which is best?
jabbasport

MAF is better for small quick spooling turbos MAP is better for larger turbos.
OK thanks for that. What's the crossover point when you'd have to go from MAF to MAP?

What's your setup at the moment?
I'd be inclinded to say anything after a K04 turbo you'd probably be better off using a boost referenced controller.
Kev
Hybrid GT2X, in the region of 300bhp.

What boost pressure you running?
Kev
21psi. 386cc injectors @ 4-bar fuel pressure.

I'd go for the 1.8t controller which is selectable between MAF or MAP and switch the system over to MAP referenced control.
Something like a 175ml nozzle and then supply a larger one aswell for you to experiment with...
OK. After speaking to Scott @ USRT he recommended the MAP controller and a twin nozzle setup with a 225cc nozzle right after the IC and a 60cc nozzle up by the throttle body.

Sounds like a good idea. 225cc for chargecooling and the 60cc for more ignition advance.
I'd say 175 and 60 for yours, Rob.
I'm running 175 at the moment and am upgrading to 175+60. :)
I've got a calculator somewhere....
Well Scott is supposed to be the WMI guru and he calculated it out based on everything my car is running. But I can't argue with your results!
One big question guys, I read that methanol corrodes alloy - so won't WMI be bad for any alloy pipes etc. in the system, including the throttle body? I've heard of a few TB's failing due to WMI?

Yes I agree with what you say on Scott. We calculated mine should be running 225cc nozzle total. (I'm running 175 at the moment, not at 40% mix and 150 psi, not the max 180.

I think it's a risk Rob and something to be aware of. Wilko's been using it seriously for longer than me without a prob. I've done 11,000 miles without a prob on it - apart from maybe it causing me to need to service a sticking 007 early.
Makes me wary of it now, wouldn't like to get corrosion on my alloy IC pipes, TB and inlet manifold. I was going to mount the first big nozzle on an alloy IC pipe just after the intercooler and the small one on the silicone hose just before the TB.

no signs of any corrosion on any of my pipework, running 50/50 mix in badgerwagen.

What mileage have you done on wmi, Bill?
Cool, maybe it's pure methanol that corrodes alloy then, sounds like it will be okay, you've been running WMI a long time Bill haven't you? I know Barry has had it for 4 years. Probably worrying about nothing.

I think its more of a problem if its being injected before the IC. I have heard of it messing up cores but its just because of how thin the tubes are through the core.
Actual pipe work shouldnt be affected. :)

What mileage have you done on wmi, Bill?
milage minimal, age of install and tank full of water/meth sat in it, 2-3 years thus far.
no visible corrosion
rebuild of the car has had all the pipes off it etc, and eveyrthing is normal no sign of anything, tbody etc pipe to it, all normal to look at
From wikipedia
One of the drawbacks of methanol as a fuel is its corrosivity to some metals, including aluminum. Methanol, although a weak acid, attacks the oxide coating that normally protects the aluminium from corrosion:
6 CH3OH + Al2O3 → 2 Al(OCH3)3 + 3 H2O
The resulting methoxide salts are soluble in methanol, resulting in clean aluminum surface, which is readily oxidized by some dissolved oxygen. Also the methanol can act as an oxidizer:
6 CH3OH + 2 Al → 2 Al(OCH3)3 + 3 H2
This reciprocal process effectively fuels corrosion until either the metal is eaten away or the concentration of CH3OH is negligible. Concerns with methanol's corrosivity have been addressed by using methanol compatible materials, and fuel additives that serve as corrosion inhibitors.
My alloy surfaces are nice and bright! :D
Ok, sounds fine then, good to know! As soon as baffled sump is sold WMI kit will be bought. I might just go for a single 225cc nozzle rather than twin nozzles though, for a simpler install.
You got me thinking about a corrosion inhibitor. While I haven't come up with an answer yet, I found this of interest.
POWER BOOSTING FLUIDS
It used to be commonplace for large piston engines to require special fluids to increase their take-off power. Similar injection systems are also incorporated in some turbo-jet and turbo-prop engines. The power increase is achieved by cooling the air consumed, to raise its density and thereby increase the weight of air available for combustion. This effect can be obtained by using water alone but it is usual to inject a mixture of methanol and water to produce a greater degree of evaporative cooling and also to provide additional fuel energy.
For piston engines, methanol/water mixtures are used and these may have 1 percent of a corrosion inhibiting oil added. The injection system may be used to compensate for the power lost when operating under high temperature and/or high altitude conditions (i.e. with low air densities) or to obtain increased take-off power under normal atmospheric conditions, by permitting higher boost pressure for a short period.
Both water alone and methanol/water mixtures are used in gas turbine engines, principally to restore the take-off power (or thrust) lost when operating under low air density conditions. Use of a corrosion inhibitor in power boost fluids supplied for these engines is not permitted.
The methanol and water used must be of very high quality to avoid formation of engine deposits. The water must be either demineralised or distilled and the only adulterant permitted in the methanol is up to 0.5 per cent of pyridine if required by local regulations as a de-naturant. In the past there were several different grades of water/methanol mixtures, e.g. 45/55/0 for turbine engines, 50/50/0 for piston engines (this was also available with 1% corrosion inhibiting oil and was designated 50/50/1) and 60/40/0, however, with decreasing demand Shell now only supplies 45/55/0. The table shows the principal characteristics of Shell demineralised water and of the commonly used methanol/water blend.
Got reassurance from Scott:
"A 50/50 concentration of water/methanol will absolutely not corrode
anything. You'd see such issues with more than a 75% proportion of the
alcohol. Such a mix would be counterproductive, however, since it's actually
the water that provides most of the benefits. The alcohol is there only to
make the tuning easier and also to better balance the distribution between
the cylinders."
I think a dash of this (http://www.opieoils.co.uk/p-819-silkolene-pro-cca-ultra-advanced-corrosion-inhibitor-for-automotive.aspx) might do the trick. I'll investigate further...
Looks like I've got the baffled sump sold, so next week is WMI time! :D
