Please look over my plan .. W/I Audit

wizegi///m3 · #1 23-10-2007, 05:02 PM

Well .. after reading and reading about W/I for weeks now I think i am finally ready to post up my plan and would like to know everyone opinion.

First off lets fill you in on the platform:

2004 BMW M3
3.2 Liter s54 (Fully Built 9.5:1)
Vortech T1 Blower
Discovery-Automotive Dual Core Aftercooler
Planned boost level 18psi

Planned Water Injection setup:

Aquamist HFS-5
RSR Water Injection 63cc Nozzles in a dedicated water rail

i.e.

I plan to run 6 x 63cc injectors (@100psi), one in each throttle body with a 50% water / 50% methanol mix.

So there is some background, here are some questions I have.

Does the HFS-5 Pump "have" to be located in the trunk? Can it be placed in an isolated area in the nose of the car?
My washer tank is 5 liters (5000cc), would this be enough during say a spirited tank full of fuel, or should I just plan to but a couple gallons in the trunk and if so that of course means the pump goes back there.

I guess that is enough to begin the discussion. I am looking for best practices and setups.

Thanks for reading :-)

Hello Carman,

I have been fully occupied with development recently and a buit short of time visit the forum.

The RSR manifold is a nice looking one. My only concern is the material used, water and methanol is not good for alunimium. We made intercooler spraying rails in either stainless or brass. It is not as pretty but functional.

It may not be appropiate mechanically but may be modified to suit.

Here are some pictures of the rail:

Thx for the tip Richard.

The only thing I am using from RSR are there W/I nozzles. I am having a rail built locally out of stainless. I will post pictures when it is done.

The pictures above where only to act as guides to what I wanted to do.

Richard,

Do you have W/I nozzles that can be screwed into a rail and then press fit into my manifold? This would save me from having to goto RSR and keep it all Aquamist.

I was planning to do approx 70cc's per cylinder, so what ever nozzle that translates to at 100psi. (I am taking off about 25psi for the use of a rail as opposed to a direct line)

The only reason I am thinking screw in type is that if i need more water in the future I do not want to have to make another rail.
