That's plus VAT.

 

Plus a few fittings and the tank.

Nice results, well done, I bet loads of people will install this now.

Yeah that

Afr should be fine with water only, will change with meth, the probs with afr and meth are usually related to running on a boost or linear progressive activation. Hence does not adapt to engine requirements at different loads and revs. We hope tying it to fuel delivery of the injectors will get round this problem. Although as the car stands meth is pointless I think, can't run more power on standard engine, its all about consistency. It may be possible to use less fuel as an in cylinder cooler though. I belive the exhaust valve temps are one of the worries and this is where the cooling effect should also help. Neil I did tell you a wide band would be usefull but you forgot as usuall :-P

[Acidpopstar]

Pffft. Lost count of all the stuff I've bought for that car over the last 8 months.

 

How much is a wide band?

[Crabash]

I can supply one for 8 million quid.

Not looked really but i think they were about 150? I'm sure someone will be able to point you in the right direction.

The problem with methanol is that it eats aluminium, you are better off in the long run not using it unless you need to. Your results with water look fine, the Klassen maps usually only start to retard ignition when IATs reach 45 degrees centigrade, so if just water spray can keep you under or near that I'd stick with it.

[Crabash]

It eats it when left standing as puddles, not an issue. It is vapor once in the intake.

Isn't the inlet manifold aluminium? When I considered using it on Nipper I realised it would collect in the bottom of this.

[Crabash]

It won't, it does not spray when off throttle and anything that goes in there virtually instantly turns to vapor. I guess a poorly thought out system could allow it through when it shouldn't and collect there on a cold non running engine.

Get an innovate LC-2 wideband kit off ebay. No more than £150 and comes with an AFR gauge. Simple to wire up and just earth on ecu ground. PS. Expect to be part of a WI collective sooner than you think.

What weight do you think this has added to the car when the tank is filled? Also how long would a tank last on say a track day? If I was to go down this route I'd want to keep it water only. Not only for the mapping issues but also the fact you can get water where you can get petrol. so easy to keep topped up and maintained. I did think that the windscreen washer bottle would be put to better use as the tank for the WI? Bit more weight upfront so less bags of sand needed..

Its better to design an intercooler/charge cooler that gives the required performance imho.

 

Too much to go wrong with W/I, that extra weight and complexity combined with the constant filling up and the worry that you will hit empty.

 

Yes it works, mainly used in rallying back in the day to get around not having a big enough intercooler (due to regs).

[Crabash]

Weight depends on tank size but I would say 4kg plus the tank.

Rate of use yet to be finalised all I have so far is Neils unscientific report of 2" gone from tank in 1 session and some road driving. Based on other reports I would estimate 1:10 ratio with fuel so around one 5 litre tank per tank of petrol max, maybe a little more when on track.

Unless you are chasing power the WI alone is all you need, it keeps temps down and power consistant, will allow a little headroom for tuning the adv. It may allow you to take a little fuel out of the ecu map and save what you spend on water too, will be looking at this myself.

Yes but thats exactly the prob with the SC engine in the VX, bigger rad still does not do that good a job and don't forget bigger charge cooler systems hold more water as well so they are even more weight.

Problem is the manifold and always will be, WI does not care about that.

1 litre = 1 kg, I'll let you do the rest

So the pump, tank and controller + wiring and injectors weigh nothing Ray?
