hfs-4 fpblack 2.3
Hi all,
I just bought an hfs-4 kit from aquamist and after some reading and looking up im a little confused.
I m currently running 31psi with the turbo on normal pump fuel. My tuner said that it has no advantage to up the boost as i ll gain nothing and that it is too risky with the timing so with the aquamist i hope to get 34psi all the way with a 50/50mix.
I just want to be sure that i ll install the correct nozzles as the mapper comes only every 2 months. This is my setup:
-2.3 engine
-ported and polished head with std size valves
-map rev3 intake
-2.5 ic piping
-3.5inch ets ic
-65mm milspec
-jun 264 cams
-1250cc injectors
-fpblack turbo
-so, if i calculate i need two 1.2 nozzles to be installed? is this correct?
-The best place i install them is between the bov and throttle body and best as far as possible from the throttle body?
-what power gain ll i have with adding 3psi boost or ll it be safe for more?
thx

I would steer clear of any methanol injection. Just something else to fail. The simpler the setup the simpler trouble shooting issues and easier to monitor. What are your power goals? Are you on 91 oct? What turbo? Seems like money could be better spent else where. Bigger cams, turbo, e85 if available.

Ideally, as far away from the throttle as possible. It will allow more evaporation time and better droplet distribution to each cylinder.
Water injection is a well proven method of pushing the power limit over the conventional tuning technique. The power gain will depend on the skill of the tuner, it is compared to put race fuel in your tank and not tune for it.
You will get power increase without the additional 3psi but it appears your tuner is not very at ease with wmi integration.
The HFS4 has a good failsafe that will automatically drop boost in the event of under-, over- flow and electrical power loss.
If your tuner is familiar with tephra's alt-map patch, it is the best failsafe option.

E85 is only a recent option compared to wmi , no one knows the long term effect. If you want to compare apple to apple, run 85% methanol or run E25. E85 does nothing to charge air cooling.
All WRC teams used water injection for 16 years until it was banned due to cost, they were not limiting themselves with only cams and turbos.
