WMI tuning and results Part 2

[robos4]

Awesome results!!

That's mighty big gains! You would def want to go direct port injection pushing it that hard, you must have a rather large Meth tank with that many nozzles.

What Dyno was this on sorry?

How does it feel to drive now with 35psi? spin the wheels much?? lol

Do you track EGT? what is that looking like?

Well done again!

This was on a chassis dyno.

Only driven it on 30psi (352kw) so far. Its actually quite scary to drive. The acceleration is quite brutal, even with traction issues. It broke traction in third gear at 140km!

EGTs were showing a max of 890 degrees C. We see the same EGTs at 21 psi without water meth injection as we do at 35psi with water meth injection.

Go to the Sydney roll drags this Friday night and watch a Datsun (R32) with V6 twin turbo running RWD over 900hp and my traction control set up, only way to do this and its easy to drive, turns scary into fast and easy dare I say it.

I have an R34 GTR customer just finished up now where we are at the limit of an EFR9180 turbocharger (spinning it too fast) it constantly sits on the knock limit (Syvecs ECU) and utilizing all of the power of WM50 with correct fuel mixture allowed by M&W CDI only.

Once you get a handle on some professional electronics and correct ignition you will see what seemed like a limit now is a base line performance level when you and your people involved build some more experience.

theboostshack, making some good power now , did you try different mixtures of water/meth like 50/50 etc. Ive tried everything from 10%meth to 60% and made little difference to the knock limit ( reading the plugs ). Whats your fuel flow total and water/meth total? About the same amount of ignition from 21psi to 35psi? Cheers

Thanks Peter. We're still just scratching the surface with water meth injection and have a lot more testing and upgrades planned for the near future. We have had some good fortune after being called on to assist some of Richard's Australian customers. We have been providing assistance with the system selection and procurement, facilitating installation and set up, and assisting with the tuning of Aquamist systems. This year, we plan on building on what we have learnt so far and expand on the service we currently provide to existing and potential Aquamist customers here in Australia.
Cheers.

M&W CDI is the only way with this if you are serious, we are SERIOUS!
100kph to 200kph in 4.951 seconds in fat kunt R34 4WD datsun with OEM syncro gearbox, its fast, reliable and durable. Even with the best semi slick tires we need GPS based traction control to stop uncontrollable wheel spin, WM50 going through all of the below jets!

Proper jet location for a direct port system. In line, same side and close to fuel injector location. Like it.

Did an EVO10 Bitsashitty today with one of these but no port injection and its not as nice. Also thanks to LR/Syvecs ECU and RR developed knock control strategy it covered the lack luster install which saw the WI line come off!!!

I post that up for the benefit of others, if you are relying on your water injection system and you do not have one of these computers that can counter any eventuality then you are asking for a world of pain.

WI is great but its just like any other sub system in the car, don't come crying or saying XYZ is shit cause your engine detonated. For all the clowns out there who say your are just making it more complex then come talk to me when your ECU and 'Tuna' can counter a fuel injector failure causing instant fuel leak and lean out on one cylinder, saw that last week and again thanks to what we do the ECU (with proper programming) first ramped up the fueling due to loss if fuel pressure, then CLL kicked in as well, and finally after the knock control in the offending cylinder caught within one engine cycle the knock prior to pre igntion starting and shut down that cylinder, all at 8000rpm and we are talking less than one hundred of a second, full power, engine killing event on any other system. 100k engine set up saved, fixed issue, drove home, ran comp test, all pots perfect and back over 1100bhp the next day. WI in this day and age with proper electronics is so easy and safe... its the ultimate in engine performance.

Spend the money once and do it right and it will serve you well, the initial cost is long forgotten but the price for being a cheap ass internet trolling information whore is a painful gift that keeps on giving long after the feeling of saving a few grand getting LINK'd to the wrong ECU and shit advice

RR,

Exactly the same setup as mine and location too (Evo X for me).

Question, how do you manage the lines evaporating due to the heat when in traffic? do you have a built in purge?

Cheers

I used extended tip in fueling (accleration fueling) to bridge the fill delay.

With a sophisticated programmable ECU, you could a squirt a litte every minute or so during normal operation with minimal fluid use.
If you use jets with integrated check valves, this is much less of an issue.
