Please look over my plan .. W/I Audit

[wizegi///m3]

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 :-)
