water / methanol injection questions

Prj, do you have any dyno data on any sort of turbo car with a before and after WM. I don't doubt for one second what you're saying but I can't seem to find that comparison anywhere.

If you take the high end stuff like the aquamist product mentioned earlier I can't understand why that information isn't all over the place.

Jimbo's thread on Audisrs I believe has a before and after

and borrowed a pic posted by Doug:

A nice 45.3 ps gain and 32NM with a nice chunky extra engine security from cooler temps and better octane

Bruce-M:

Your DVC-30 stage 2 kit with 30 PSI boost controller is that absolut or relative boost?

[Bruce-m]

Absolute boost, they don't read vacumm.

I will try to get some, but can't promise anything.

That means around 1.4 bar as max boost on the controller if vacuum is 0.7 bar. That is not much I guess.
I'm running close to 1.9 bar boost so I guess I would need your DVC-100 instead then?

How are you planning to tune Motronic for water/meth mix if you don't map switch?
You'll just run rich and lose power... Controller needs some sort of output to show if it's on or off... at the very least.

[Bruce-m]

They don't read vacuum only positive boost so the DVC-30 is designed for up to 2bar boost (30 psi), you won't need the DVC-100.

[Bruce-m]

Jimbo didn't tune for water Meth and switch maps & look at his gains, no loss there.

Ok then it is not absolute but relative pressure since absolute pressure is measured from 100% vacuum.

[Bruce-m]

Yes your right sorry, relative is the boost pressure a car is running.

I want to update my water injection with the aquamist HSV1 solenoid valve and the inline relay if anyone knows where i can get them because Aquamist do a different kit now

Yeah, and he was running ME7, not M2.3.2.
Nice comparing apples to oranges. ME7 fuel trims are completely different to M2.3.2, where there are none on boost.

If you have a tune that is mapped to run fairly rich, say 11.5, you will easily dip to high tens and lose power.
I mean, I don't mind you promoting your product, but you could do so abiding by forum rules (sponsorship) and without misleading information.

How many S2's have you mapped on meth?
