HA! That's exactly what I need. I sure hope the track is still in place when I look, if it isn't I've got some annoying troubleshooting to do.

Only the HFS-6 requires the cutting of track. If you have HFS-3 or 4, just pull off the jumper link.

I'm turning my system into an intercooler sprayer using a DEI Spray loop. Can I use tap water in the system since I'm not using the jets for spraying? My understanding is that the jets were really sensitive to clogging.

If I may, why don't you sell the HFS-3, and then buy a lesser system?

In case one day E85 becomes unavailable for me in the future. I can go right back to meth injection. I know this is overkill for an intercooler sprayer.

I was gonna offer to trade you for a different kit if you were just doing it because it was there.

Yes I have the 6. Your documentation says by default the High boost disable is off. You can see on the PCB picture in the manual, and on my production unit (hfs-6 v3?) it's actually enabled from the factory, so high boost is disabled when the unit is off.

I think documentation should just be updated to state it's on from the factory.

Either way, this fixed my issue, now getting above spring pressure when the gauge is off, yay!

You can always use tap water if clogging is not important. Soak the jet in lime remover occasionally.

It is much safer for us to make "system off" failsafe as default unless the user decides the less safer option otherwise.

So the pump and FAV are ok? Would they need maintenance due to tap water?

There is less chance of clogging compared to the jets. Every six months or so put some diluted lime scale remover in the tank. Flush the system out by re-cycling the same fluid back to the tank for several times. One minute on and one minute off to minimise the heat build up in the FAV.

You can use the TST jumper on the H6.

Any reason I shouldn't mount my jets under my TMIC? Trying to keep the bay clean. Only downsides I can think of are oil and dirt build up (but the 160 psi should clear that quickly) and I'll only see the plumbing during oil changes, making it harder to catch something before it goes wrong (but that's why I went with your kit- great fail safes).

Also... Whoa! These two charts are quite different. Which should I use to select jets? The one from the manual or the one online?

Mine 2 jets are mounted on the bottom side right before the TB so the install is hidden.

I've run mine underneath like that for 5 years on 2 different intercoolers.

If your intercooler is too thin at the output you can either weld a plate on to thread the jet adapter(s) into or you can install the jet adapter(s) off to the side where the metal is thicker and you can get enough thread.

I get a little oil perspiration around the jet adapters but it's only aesthetic. Figure whatever oil film you get in your intercooler will eventually seep through and get the exterior of the jet(s) and line(s) grimy. I have a catch can but it still happens after a year or two. It might not happen if you don't track the car. You should be changing out those lines, pump to jets, every few years anyway -- preventive maintenance is imperative with methanol injection.

Hmmm. That sounds like a win to me.

I have a Process West, don't expect any issues with wall thickness.

Shame about the oil though, not enough reason to change my design.

I have a Process West too -- the jet adapters had to go off to the side in respect to the center of the outlet pipe to get enough thread.

You also might get more oil pooling if you go dead center to the outlet since the adapters will be at the lowest point of the diameter

I made the mistake of installing jet adapters into a charge pipe on my turbo Ford with barely enough thread to catch. One sits pretty, the other spins and leaks randomly as temperatures fluctuate.

Got pics?

I was planning on nailing the center in the inlet, and going slightly closer to the firewall on the outlet side. But I haven't had it off yet to check wall thicknesses.

EDIT: Still pretty disconcerted about that discrepancy in jet flow values.

I will take some pictures this week and send them over. The car is in pieces at the shop so it will be an easy job. For what it's worth I don't have any jets at the inlet, just 2 at the outlet.

I believe the online chart is compensated for pumping losses so I would use that one to choose your jets. The uncompensated chart in the manual is optimistic and not practical. Once you have the jets connect everything together for a test run and time how long it takes to fill a liter bottle (or measure a graduated cylinder that has been filled for one minute). The actual flow rate will obviously not be exactly what you aimed for but it should be close -- you can fine tune at this point with different nozzle sizes.

I expect Richard from Aquamist will chime in about this soon enough.

Quotating the exact flow rate of the nozzle will be more mis-leading for the end user. Use the compensated flow rate is more accurate for a specific aquamist kit. Flow chart from other aquamist kit has been copied and pasted out of context all over the internet.

Every aquamist kit comes with its own flow chart in the user manual. Don't get yourself confused on an unknown flow charts posted in the internet.

Both are from your sight ;-)

I'll use the one from the manual, thank you gents.

CLimbhigh, Aquamist has used at least 3, and I think I can say 4 almost certainly. The Shurflo was rated at 125psi, the current Aquatec is set at 160psi, and the older race pumps were 100 maybe. The Howerton Motorcycle kit/PWI-2 was/is a flojet pump, and from what I understand the piston pump from the PWI-1 wasn't the same as the race pump, so yes, different pumps will have different flow rates, just like different cars will have different dyno numbers. Find the one for the kit you use, follow, profit.

Hmmm. I suppose in my mind pump flow and PSI are unrelated with respect to jet flow.

Presumably, the pump pressurizes the lines and continues to supply an excess of flow (greater than flow potential of the jets), part of which is jetted and the remainder is recirculated. I was fairly certain this is how the HFS-6 worked, but having done so much research, I could certainly be garbled.

All that means is that the jet can be qualified without concern for the pump, so my 137 psi targeted system with 600-800cc of mix injection could go 2 ways according to the above graphs.

I'd chosen the .6 and 1mm jets based on the online graph. Looking at the plot from the manual for the same jets, I require something more like the .5 and the .9mm (I think... It's early and I don't have my research notes with me).

Point is, I needed to buy jets, the smaller ones are not included in the kits, and I wanted it to all show up at once. ;-)

I ended up buying the .5mm: as its still in range for the lower reading graph. I'll post a video of my flow tests when they're done.

Thanks all for your help.
