About to get retuned on water meth, but I'm after opinions on what's the highest boost and hp I should be aiming for? I know it's roughly the same as e85 but not as good so I don't want to push it at the same level as that.

I wanted to push it hard but not over the limit, the tune will switch back to normal 98 map when low level is sensed for safety.

It's a stock rb25det with all supporting mods.

i talked to pete at nistune tonight, going to go back to the dyno again in 4-6weeks hopefully as i replaced my blow-off valve

and it was leaking 7psi when i tuned it last time.//so the poor hypergears G3 was running 26ish psi to get 19psi in manifold.

And had no comp flow left.

Comes up on boost much harder now.

want to check out cold start and road tune aswell as its a daily/holiday car

wmi been on car now for 12months, had no problems once i installed the 30 micron filter, clean it out everytime i do oil

change at 5000km. seems to be a bit of shit in the meth i have been using. Without the filter you would be asking for trouble, but

it catches it all, nozzle has been perfect

cheers

darren

checked every 5000km, but to be honest, the jet has been fine, i only had problems with it before fitting the aem filter.

My wife drives car everday, and it switches on at least once a day going up the hill to take kids to school, so maybe that keeps it

from any build up aswell?

cheers

LMAO @ wife using WMI taking kids to school

That is all.

darren,

where did you get the filter?

also where in the system is it installed?

andrew

ebay, its installed before the solenoid. If you pump is separate to your tank you could put it before you pump.

I can't as i have a pump mounted in tank setup

I woudn't run a system without one as there seems to be a bit of shit in the meth from the speed shop, would clog up a jet very easily, judging by

the shit i am cleaning of the filter mesh, woudn't bother a fuel system

Well done at the drags aswell andrew..your .cars a beast, real nice street setup!

Also to point out here, as its not written much on net at all , DON'T use teflon tape or such on fittings, only proper thread sealant

unless you want to lose a motor, the shit ends up getting sucked through and WILL end up in your jet, its only a matter of time.....

might not happen overnight..but it will happen..lol

I see some forums say it alright..it is not, even if you use a small amount

cheers

darren

Thanks darren,its great fun on the road, and actually gets more traction on the street.

did you go out to the drags for a look? See the rb30 stagea?

Ive only got the crappy looking in tank filter, will look at another, does putting one on the pressure side of the pump effect injector flow?

nah man, was up river that day, didn't even know it was on, would have been good to catch up

Yeh that stagea is the guy with the username Superben on here, he hasn't updated his time here. Such a cool sleeper, would smash many a unsuspecting skyline..haha

cheers

I still dont get why not many people are using wmi as opposed to e85 - cheaper, can use only water and fill up wherever, similar power gains if Im correct...

Possibly because it's illegal? Is it not?

Possibly because it's illegal? Is it not?

Nat it's perfectly legal from what others have said

Because it doesn't effect the emissions of the car

I think less people run it because it's more things that can go wrong.

Nozzle gets clogged and there goes your engine, water runs out and there goes your engine, stops spraying for a short time and there goes your engine.

Just too many things compared to a nice E85 setup

Buy a system with a good failsafe feature on it and none of those things will be an issue. I'll be wiring my aquamist into the ecu so it switches back to my soft tune if there is any problems. Thinking I may also use it to disable the boost controller through a relay

Things that can go wrong as noted by Kasko: *nozzle gets clogged>>can say same for fuel injectors hence detonation/engine gone

*Stops spraying for short time>>can say same for fuel injectors hence knocking/detonation/engine gone

*runs out of water>>some systems have failsafe devices like warning light/level indicator etc

So really the issues above are the same as for other systems like fuel etc; in the car..or is it not?? E85 on the other hand costs a lot more- very few servos around/ poor fuel economy/starting etc etc

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
