[rx7veilside]

i am using the uk rear washer bottle..depend on how often u use the boost as reagards refilling..i wldnt leave it longer than a few days in between though.better to keep it topped up

Fuel cell in the boot - 5 gallon, but i tend to run it half full.

Max is that half water, half meth?

Being a UK car, I have the rear washer bottle, but I prefer to keep that as a windscreen container.

100% water most of the time, around 20% meth when I remember to put some in  :Hammer

Just got to work out where to put the pumps now.

Remind me, why do we do this?

It stops us getting bored - watching big brother, and other brain destroying reality shows

The Power FC corrects for air temperature, yes.

You could probably gain around 5-10% power by leaning the a/f\'s out.

But you are low on safety margin if things go pete tong

Sure - i think the only way i can go with water injection is to not tune for it. Seems a shame, but its the only way to be fool proof.

Now, is there a formula for AIT drop vs power increase?

stupid question mode on (yes my specialist subject) how do you test for what with WI cause i think mine has stopped doing it\'s funky thing judgiung from the intake temps not going down now when i give it some boost. Unscrewed the actual nozzle & i can blow thru it so presume it\'s not blocked (awaits to be told wrong) & it has water in bottle. HGaven\'t checked for any loose pipes etc as yet but is there an easy way to test various bits. I recall Pip used a hand held thing he plumbed into pipes to squeeze & give boost without engine being on, was suggested elsewhere i kud try a footpump with small adapter to do this but seemed a bit bodge to me....
Guess there\'s not much to go on but any cunning plans or help wood be appreciated?

Can you not trick the pump into working? Might be a fuse or something.

thats kinda what i was guna try & do by sticking sum pressure in the pipe so it thought it was over .5 bar or so & should work, if not then obviously with kmy skills i\'ll need to get my wallet out & get sum1 with knowledge to check such things
