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

    • I suppose that's true. Barring almost any situation, I'll never sell so what the market does is kind of irrelevant to me. It's possible I'd make most of my money back. That spreadsheet I mentioned? Maybe I could make back more than what the car's total costs thus far are, but the parts and all that is possibly a different story... Thanks for reading. It was certainly a good moment and just makes the ties to the car that much stronger. It's exciting that the option will be there to bring it over, however I have some plans with a shop that may end up keeping the car there longer, not sure. Coupled with the fact I want to move there and haven't solidified any path yet. So in a way, it feels like I'm in a limbo state that is uncertain; time will tell.
    • No worries, everything worked out in the end. I just wanted to make the point that it doesn't matter where it comes from (I.E Australia), it can be broken or improperly built. I would still purchase from these companies in the future. B2R - Not certain how that finished, this was on a car I wired a few things and street tuned. I know the owner ended up shipping the motor back to Australia for investigation. Hopefully some of it is covered under warranty.  Turbosmart - I always pressure test everything that goes on my car. It's a habit from my career in oil and gas. I run two 40mm's and both had major leaks from the actuator to exhaust portion through the shaft. I returned both, they shipped me back two and one was leaking and the other had a 38mm top (40mm gate with 38mm actuator cap, no idea how that happens). Eventually after a lot of back and forth I found myself with two non-leaking gates. I believe this happens a lot more then people would like to believe but you would never know if you don't pressure test them prior to installation. Crank Motorsport - Issued a full refund and let me keep the seat rails. I turned them into scrap metal for other projects. GKTech - Shipped me out a replacement and asked that I modify it as per my idea and that they would do the same for a future revision. ATP - Can just needed a large shim to bolt up properly.  Haltech - They started an actual proper Beta channel for firmware's a few months back and stopped using the general public for testing. I'm now much happier.  Speedtek - f**k Speedtek. I would love to watch them burn.     
    • I've got a Turbosmart wastegate, ATP catch can, many GK Tech parts and Haltech everything. Everything's been perfect, sorry to hear your experience wasn't the same
    • The only high-power RB I've personally seen go pop after running for all of an hour on a dyno was built by B2R, while being remotely tuned by B2R. The only wastegates I've ever had leak like a sieve, return, still leak, return and get shipped back the wrong ones were from Turbosmart. The only final drive that I've ever purchased that were unusable, twice... were from Speedtek. The only seat mounts that I've ever purchased that placed the seats in the door frame were from Crank Motorsport. The only poorly designed parts that I had the manufacturer confirm should have been designed as per what I mentioned were from GKTech. The only ECU I've had firmware updates consistently break things are Haltech. The only catch can I've purchased that didn't fit in its advertised spot was from ATP. So forth and so on... Moral of the story, doesn't matter where it's from. Do your research beforehand and stick with products and companies you've trusted in the past.    @joshuaho96 If you want it done right, do it yourself.
