The meth will come out where ever the BOV is located.

Default Pump above tank

Is it possible/recommended to put the pump above the tank with a HFS3 system?

Originally the pump head was going to be at the same level as the bottom of my washer tank, but discovered in test fitting that the fog lights are in the way. I need to move the pump up and rotate it sideways for it to fit. The aquatec pump that comes with the system is rated as self priming, but will it maintain prime for long periods of time?

Also is there any reason to run a primer pump with the newer pumps, or was that only helpful for the older pump designs?

Edit: I need to install it how Legacy_GT_Pilot did over at LGT.com. though with the newer aquatec pump and the FAV back on the firewall.

We recommend not to install the HFS3 pump in the engine bay as the bearing will seize quickly. You will also void the warranty by not putting it in the truck.

I bought a used hfs 1, with DDS3 V9 controller. It works fine, but does not turn off the pump if the fluid level is low or empty...the pump keeps running. Is there something I am missing? I connected the level switch as the instructions indicate to pins 19 and 20.

Would you guys say that the HFS-3 is adequate for a DD car? I'm mainly looking for knock protection, but also want the added cooling benefit.

One stupid question. I have hsf6 version and am having flow control module(like fast acting valve) in engine bay, no way to find the replacement. Can I simply buy hsf4 control panel and fast acting valve, will this work? Bc I already have tanks, gauge, ecu connected to cable, wondering if this will work.*
Can't get hold of Richard from aquamist...*
Any help would be appreciated.*
Thank you.

its been awfully quite here

I was bored to decided to redo with things with my HFS 3

I ditched my diy surge tank (oem spec c tank is very slosh happy on turns) and decided to baffle the big tank. I looked what 4x4 guys are using in their fuel cells, and followed that route. I looked at different plastic compounds and their chem resistances, and found out that polypropylene is meth resistant (and cheap!)



so I bought your casual ****ster piping, and cut it in even 6cm long pieces (the OD is 40mm, 50mm doesn't fit into the tank because of the bend), and them trimming each of them to get rid of debris



surprisingly I had to cut 3 meters of piping to fill the tank, so I was concerned that I might loose a lot of volume, as that pipe has thick walls (3mm). However, when I filled the tank I estimated that approximately only 1.2 liters out of 12 was lost due to the baffling - not bad at all, and still beats the OEM 4 liter tank!

next, I decided to move the pump to the spare tire well, this way the pump is hidden and is also sitting lower than the water level. I fabricated a bracket so that I have quick access to the spare tire, should I need it





not seen on the picture, but I cut a regular rubber hose and put it on the bottom of the angle that sits on the spare wheel







I am venting the tank through the tank, and ran the 4mm nylon line into the trunk breather flaps
the relay is hidden on the right side of the trunk behind the plastic liners, control module is hidden in the glove box
also, I used OEM Spec C tank level sensor because I didn't feel like drilling more holes, and besides with the baffle in the tank aquamist sensor would no longer work

I plan to run few full tanks before washing the filter, as I am sure debris from the cut pieces will flow out eventually

engine view, the valve is located near the fuse box, 4mm line runs to the intake charge pipe that Y's to accommodate 2 jets



I think I am finally happy with it

kudos to Richard for answering my late friday emails!

Nice job ! I did something similar with my pup in the tirewell. Worked out well!

Hey I have a few questions about the hsf-3 kit. My car is currently getting rebuilt for more power, and I recently moved and have no E85 so methanol is my only other cost effective option I can think of with fueling. I was at 27 psi at 550whp on my sti and would like to get around or above that power level. Have you ever heard of anyone getting that much power from water methanol? If so is there a recommendation on nozzle sizes and how many nozzles I should use? Iíve seen only a few people on 91oct and meth about 500hp so Iím hesitant to get the kit if it canít reach my hp goal

Is your engine being upgraded in your rebuild? If it is, it would be helpful to list the specs. That way people would have a fighting chance to answer your question more accurately.
Just to be sure, you know that you aren't actually using methanol as a fuel substitute. The water/alcohol mix is to lower the intake charge temperature by evaporative cooling, and to slow the flame front propagation. This allows you to advance the timing and raise the pressure levels to make more power while keeping detonation in check.
If you put in a matched turbo that is working in is optimum efficiency range (probably rotated mount), FMIC, port out the heads, re-valve, change cams (AVCS on yours?), sleeve the deck, lower the compression ratio, and put in forged rotating and reciprocating assemblies, do headers, exhaust w/ hi-flow cat, dial in your EM, then yes, you can reach your goals with the help of water injection and 91 octane.

@zaxrex

The engine has all forged internals, and is sleeved. 99.75 bore. 1300cc injectors with a Walbro 450 pump. Fullrace equal length twin scroll kit with a Borgwarner s362sxe turbo. Full race rotated fmic. BC 272 cams, 1mm over valves. 8.5-1 compression. Canít remember off the top of my head the other parts. Yes it has Avcs.

Aquamist recommends 15-20% ratio if using a 50/50 water meth mix for max power IIRC. From that you can calculate what size nozzles you need based on your injector size and max INJ duty cycle. I would run at least two nozzles. I don't have the charts in front of me but all the flow rates can be found on the aquamist website. The flows are dependent on you max boost you intend on running.

FYI, I have a 9.1:1 compression build running on ****ty CA91 octane. I was knocking easily with anything past 16 psi without WMI and made 400whp. With WMI I made 510whp @ 23 psi. Made 566whp on Q16 with a lot more boost.

I just got a new in box Perrin pwi-1 revision 2 and when i push test it sprays. When I drive the car the blue light comes on for a sec then goes off. The low flow light comes on and the orange light flashes. I have 550cc stock injectors on a jdm Ver8 Sti engine . The two pots to the right are maxed out with a 1.0mm nozzle
