Hi guys,
Ive been on this forum a while, and was part of the group buy of the HFS-3 system which i have basically just finished installing.
My engine is a Eaton supercharged 1600cc 4cyl engine, forged internals, Gapless rings, SS Valves etc etc, It runs with an FMIC, Running about 12-14psi of boost and currently has 206bhp at the wheels. It runs emerald management with EGT sensor and techedge wideband control, no knock sensing apart from egt. I bought the HFS-3 system to assist in lower intake temps and ignition timing advances.... But with a small amount of knowledge about the subject, this forum has helped me a great deal with understanding it. Just hoping a few of you could share your views and give me any help, as i will need it!
I have the system set up, but haven't decided on where to put the jet in yet, from what i see people try all sorts of things. I wanted to run the car with a 50/50 mix with running the jet in to the flow after the I/C but further enough away from the air temp sensor so the mix has enough space to fully mix and give a good reading for the sensor... Am i right in thinking this?
It the dawned on me that i do see fairly high intake temps sometimes, after 20mins or so on the rollers, i can see intake temps of about 40-45 degC on hard boost, this is mainly down to the proximity of the charger to the exhaust manifold, its well protected and has a water jacket on the charger, but it still gets warm, Id sat it operates at about 70-80 degC but im unsure on exact air exhaust temps.
Now would it be a good idea to inject a small amount of fluid in before the charger intake?? will the methanol affect the aluminium case of the charger and the aluminium I/C? Bearing in mind the injector sizes are only 380cc, so im looking at a fairly small jet anyway, 0.4-0.5mm to be precise. Would i actually see any benefit from the pre charger injection? and what size jet would be right for it as ive read that smaller jets clog up easier? and if i use this, will i be injecting too much? I will be using R/O water (Reverse Osmosis) and race methanol.
I have set it up so the failsafe and the switch on the dash swaps my maps over on the ECU, going between a W/I map and a normal map at the flick of the button, I will be using EGT to monitor the engine, and have wideband control to monitor the rest. It will be all based on my IDC, i dont plan on using any map sensor input, although i could do, is this advisable??
If anyone could give me an idea in how there eyes they would set it up, or have any information or want to give me any help then it would be greatly appreciated. I will be keeping this thread as updated as i can, its never been done before on this engine, in fact everything ive done to this car has never ever been attempted! So im well any truly in the dark on this one!!
If anyone is interested in the build thread of the car to see the work gone in to it already then please visit here:

I understand there's about 1320 posts, it gets interesting about 5 pages in to the thread, so if you get bored, i understand!
Thanks,
