Subaru STi Port Injection with HFS-6

[BakZamGai]

Hi Richard

I would like your opinion on jet placement if I were to run Port Injection on a Subaru STi.
I am running a APS Tumbler Valve Delete, with provisions for secondary injectors.
As these secondary injector ports are not predrilled, I can have them tapped for the water jets.
Do you think this position is acceptable if I were to run Port Injection?

Will the HFS-6 work with this setup? The secondary injector ports are the ones on the top.
I am concerned that the placement of the water jets will be too close to the injectors.

Essentially, the car will run a built 2.5l block with a twin-scroll GT35R with 1000cc injectors.
Also, the intention for the installation of the HFS-6 is to prevent detonation. Would you recommend a 50/50 mix with methanol? Would that provide a greater margin of safety?

Thanks!

Cheers
Dennis
