HFS-5: System over view:

- Constant pressure system - very low pressure ripple (factory set to 125psi)
- High speed PWM valve ensure accurate flow control against fuel duty cycle.
- Fast dymanic response time to load and RPM change
- Consistant droplet size due to high system pressure under all conditions.
- Powerful 150 Watt Shurflo pump motor capable of maintaining flow beyond 2 litre/minute
- DDS3 (bundled) ensures flow is monitored constantly for clogged jet or cut hose.
- 2x failsafe channels to perform advanced failsafe tasks such as boost cut, map switch, etc.
- Water and methanol compatible (0-100%)
- Available by the end of January

Any idea of estimated price? I am looking to aquamist when I get re-tuned...

Here are some pics of my install of the new Aquamist HFS-5

I tapped the #1 injector wires (the plug is circled) for the FIA2 input:

I ran 2 jets to the underside of my TMIC:

I ran the 6mm hose, the wires for the flow sensor annd injector input through this blank rubber plug in the firewall:

I ran this random piece of fuel line around the 4mm hose to protect it it just happened to read "INJECTION" when I installed it :headbang:

Thank you for the pictures, it is great help on installation.

The system is designed to deliver any conmbination of water/methanol relative to fuel flow. making tuning an engine very simple.

If any one like use to improve the system further before shipping to our dealers, please post here.

Price will be comparable to the system2d - without mention figures.

Great see those kits about to be released!!!!

I will be sure to get pictures for you today of our setup!!!

-Matt

Price will be comparable to 2d plus the DDs3 I imagine.

I just received mine from URD - I am very impressed with the quality of the components. Everything is jewel- like. I am starting install this weekend.

Is there a firm answer as to two jets or one? .8 and .9 or just .9 for a green setup?

Again - nice kit guys.

Are you offering a group buy pre sales ?

There is a good chance for this to happen, we need to get some real kits out there for some real feedback. The answer has to be yes.

Kit inventory did not specifically list number of nozzles and nozzle size.

Care to address?

Sorry, the jet comes three jets, 0.8mmm 0.9mm and 1mm. A y-piece is supplied.

So, looking at the Aquamist site, the flow for the 1.0mm jet is only 310cc, even with 2, it is only 620cc, or barely 10gph max. Am I missing something here, or is this really only for mild turbo setups. Or do the flow ratings not apply to the new shurflo pump?

I'm still hoping for a suggestion as far as one jet or two for a 49lb turbo setup - any suggestions, Richard? 350-400hp range. Thanks.

Flow is related to pressure and steadyness of the system pressure. On the site, the 310cc, 1mm jet is referred to around 5-6 bar water pressure (pulsed), the HFS uses a 125psi system pressure, bring the flow to about 500 cc/min+. This is because the new system has a non-pulsed system pressure, minus the HSV pulse. You should get about 1 litre+ of water/methanol per minute from two 1mm jets whern the HSV is fully opened.

I'm still hoping for a suggestion as far as one jet or two for a 49lb turbo setup - any suggestions, Richard? 350-400hp range. Thanks.

I always recommend two jets, about 6" apart, this will minimise gaps between injection.

350-400hp requires about 2.5-3 litres of fuel per minutes, for aggressve tune, I suggest running pure water at 15-20% w/f ratio and 20-25% m/f ratio.

1x 1mm for water only
1x 1mm for methanol

What W/M ratio are you intending to run?

50/50 is what I was using, but it was denatured/water. Do you recommend Methanol/Water instead? I'm going for retuning this coming friday, so I need to get the final hookups. The kit really is gorgeous, Richard. Hopefully I can post some picture of my spec-c tank setup.

The system can be used on either for methanol or de-natured alochol. If you go for methanol, you need to inject a bit more. BUT for 50:50 mix, 10-15% w/f ratio, makes very little difference.

Please do post some pictures.

Going for tuning tomarrow. Sorry if I sound stupid, but for a 49lb turbo setup, 350-400, do I want one 1.0mm or two jets (.8 AND .9 ) for a 50/50 mix?

Sounds like you were recommending 1 1.0 mm nozzle - correct?

Thanks for help. I'll post up some pictures after I get the wiring cleaned up a bit.

Is this system available yet? any nasioc vendors have it in stock, or have a price on it?

Also is this a "tuneable" progressive system, or because its based off injector duty cycle its always injecting the "right" ammount, you just have to tune your engine for it?

Using one 1mm jet will spray about 500cc/min at 100% duty cycle of your injector.

I suggest using 0.9mm/ 1mm for water only and 0.8mm+0.9mm for 100% methanol.

The system will be available at the vendor before March.

You can alter the ratio water/fuel or methanol/fuel ratio. you can alter the ratio by using bigger or small jets or multiple jets.

Electrically, it is not worth the risk to allow user to alter the duty cycle ratio in case it tops out and let no RPM related W/A enrichment. Changing the jet size to alter the flow ratio is safer.

All you need to do is tune the engine, the rest is all done automatically after the WI is triggered.

Richard - hopefully you are getting some sleep!

Thanks for all the calls and e-mails.

This might be a stupid question. Can it be used for road racing, with the flow rates you are discusing (1 litre per minute) for a 30 minute run I would need a 30 litre tank. Or am I missing something in the equation besides I'm not on the throttle 100% of the time.
Even if 50% throttle average, I would need a 15 litre tank.

Tagging along in hope of getting in on a Group Buy **hint hint** :D

I'm adding this to my list of Spring purchases :D

Awesome kit.

If you are running 25% water/fuel ratio, your fuel tank should be a 90-litre capacity. The system do not flow 1 litre per minute constantly, it varies with your fuel duty cycle.

I generally use 7.5 - 8 gallons of fuel in a 20 minute session, then I would need a 2 gallon water tank. 25% water / fuel ratio seems on the high side, is that be normal.?.

I presently have your 2d system.

Can you just buy the pump and use on the 2d system, if so what benefits beside running straight methanol would there be. Presently my car works very well with the 1mm jet and 30cc accumulator.

yes, it is oK to do that - but you will loose the failsafe function.

The reason for introducing this HFS-5 system is flow. Your present system is 100% methanol compatible but we do not recommend it due to safety. Same applies to the new system. Seals on both systems are not a problem

Running methanol require higher volume than water due to lower latent heat value. You can add a prioming pump on the 2d, boosting the flow up to 570cc/min.

Is the safety concern you are mentioning the safety of the motor if the methanol quits flowing, or the safety of carrying around undiluted methanol in the car?

Any updates as to when this is going to be avail?

The HFS-5 system wll be availabe from all Aquamist dealer from March. If you make the enquiry now, you will snap up the first few shipped at the time.

Meanwhile, please ask as many questions as possible.

I assume one needs an after market engine management system. Have you tested it with an accessport system?

Bo

very nice....
