Some good info there Rekin, i originally dismissed Aquamist since i seen a guy flow test, what may of been of a older style pump and with a 2 nozzle setup could only get a max of 320cc/min, but i just seen on the site they claim the new pumps run out of flow at 1600cc.. i really do like their tanks.. but i dont like the idea of the pump always being on? or does it just come on n off enough to leave the lines pressurised.

Snow Performance claim they're nozzles get good atomization, even at low pressures.. im not worried about the pressure when it starts, but im a little concerned when i lift off the throttle quickly and put it back on (like when your spinnin tyres playing with the throttle), that with the amount im planning to inject, i may end up with way more mixture in the engine than it can handle and end up with some serious hesitation issues.. has anyone had any problems with this??

The newer 220psi pumps from these companies are meant to hold a steady 220psi.. so theoretically they shouldnt pulse as much, not sure if they will still pulse when they are still starting up...

how much are you planing to inject? i have a 500-600cc nozzle on mine and havent noticed any hesitation issues.

The pump being on is exactly the same as your fuel pump. It is always on and providing constant pressure in the water lines. The controller then opens the nozzle depending how much to spray in. Just how fuel injectors work.

Snow Performance and others, have pumps which only turn on when they are activated. That means when it turns off, you will get dribbling of water into your intake due to no more pressure creating the atomizing spray. (refer to the 2 vids i posted earlier)

The hsf3 costs about $650USD compared to the other systems selling for $300USD. I took the plunge and bought one, its been sitting in its box for 3 months!

Yeh, i was hoping that they did something other than prevent siphoning, but haven't been able to find anything that suggested they could hold back any significant pressure... was looking at twin 375cc's

Price comparison: stage3 669, solenoid upgrade +50, safe injection +159 =878

HSF-6 899

not really a huge difference in price assuming theyre shipping rates arent extortion

how much was your shipping Rekin

At the end of the day, they look to be both great kits, i suppose it comes down to which ones offer the features you'll think you'll use/need more

HSF-6 is overkill, the HSF-3 is more than plenty. (and cheaper too)

I paid $44USD for shipping from http://howertonengineering.com/

a cop looks under the bonnet/in the boot and sees a nos system and you are farked, this isnt the USA you cant have a connected nos system on the street legally no matter who you get to say its safe.

Thankyou captain obvious. But you can run it at the track, where you will be doing most of the hard work... Are you going to run a knife edge tune and water/meth on the street all the time? I wouldn't, there's no need.... your not going to use 400kw on the street very often.

BTW.. nitrous is no more dangerous in a vehicle than gasoline or LPG. In fact N20 is innert and stored better...

Water/meth isn't huge in the states either... most guys are running it because availability to good fuel is limmited.... (then they see the numbers us Aussies are getting out of the same engine/turbo combo's and they want the same- so they up the knock theshold and octane with WMI).

... it is cool running around the streets in a car with 30lb of nitrous on tap (currently in the US) though. HA HA!!

Justin.

your not going to use 400kw on the street very often.

Maybe not in the city??? but out on the open road overtaking a couple of B doubles is a very normal activity and the ability to hammer it around them is very handy. The less time you spend on the other side of the road, the better off you are.

You may not use all 400kw all the time, but you definitely appreciate the urgency of the motor when you put the foot down and go!!!

I looked at the HSF-3, but i thought it didnt have the flow sensor which was an extra 300, turns out it does... so the HSV-6 doesn't offers anything more, just more adjustments, the HSV-6 flow control module does look like its been put together a little tidier, but thats about it. Do you know if the 160psi aquamist pumps are comparable to the 220 psi shurflo ones??

Theyre's other uses for water meth tho besides knife edged tunes.. even if u only get an extra 20rwhp, but manage to add a descent amount of safety into your tune provided the wmi kit is working properly.. thats a gain to me. Hell ive spent a hell of a lot more with alot less gained. Plus im pretty keen on the idea of keeping the intake temps down. Of all my friends that have nos, i dont think any of them use it any more, lol.. tho i can half see water meth ending up that way :P

Any idea anyone on how long a 20litre tank will last before it goes bad?? will it keep in a good quality sealed container??. Id prefer to have a big tank that u fill up every few months.

Cheers

Aquamist seem to know what they are doing so have no doubts in their pump selection. Send an email to howerton engineering and ask them, they are really helpful.

60Ltr fuel tank

10% = 6Ltr of water/methanol required

50:50 ratio of methanol and water = 3Ltrs of methanol & 3 ltrs of water required per 60Ltrs of fuel

Assume 60Ltrs fuel consumption per week (month = 4 weeks~)

4*3 = 12Ltrs of methanol required per month

So 20Ltrs should last you about 2 months, depending how you drive ofcourse.

If its sealed properly with no way of water entering. (methanol absorbs water, so once you mix water and meth, you will have less volume than you started off with due to the absorption)

So keep it sealed properly and it should be fine.

a check valve befor tthe nozzle is a good idea.

these guys make the best nozzle ive used 2 different ones the check valves are good to. : http://www.alcohol-injection.com/

best tank ive seen and strongest pumps: www.coolingmist.com/

ive dealt with them and had good dealings with them.

this is based on my opinion and my use of the products great with nos,i use googee methanol 50/50 with distilled water.ive had no detonation at all. car has not been tuned with it on a dyno but works well with 3-5 psi more boost.i only got it for my nos setup but its worked well with every day running so far.

then pics of some of he set up are here http://www.skylinesaustralia.com/forums/Mo...html&st=160

this is a post i did a while ago http://www.skylinesaustralia.com/forums/Wa...on-t281683.html

The placement of the check valve doesn't matter that much as long as it is in line somewhere? Or is it better off closer to the injector? I put mine close to the tank but I will change it if it's wise to do?

mattis96, SP say as close to the nozzle as you can. The solenoid is set to open when your inje ctor and/or boost level is reached, so only sprays when its open and only opens when it sprays.

But the main reason for having it is so that you don't drain your whole reservoir into your motor esp. if you park nose down on a hill. So what you have done is set your system to drain your hose length into your combustion chamber. If you aren't using your car then this fluid will pass your rings and find its way into your oil. If for some reason it doesn't get past your rings than there is the chance of hydraulic lock. ie when you go to start your motor you will be compressing water/meth and this will bend conrods/lift heads/bad shit.

Having said that the length of your hose would maybe not have that much fluid in it and it may not be all that bad + if you don't park in a steep driveway or on a hill you may never ever have a problem - but I'd change it just in case.

I contacted PowerPlus fuels ( http://www.powerplusfuel.com.au/racing-fuels.php ) if they can supply a 50:50 blend of Methanol/Water or a high quality methylated spirit (98% ethanol + 2% methanol)

The ceo emailed me saying they can provide either blend in 20Ltr or 200Ltr drums!

I'll be emailing to ask about costs. This is great news! No hazchem suit for me when dealing with 100% methanol! :blush:

closer to the injector so the pressure is always in the line or you will get a delay.i run two but thats just me one at the tank and one at the injector

Dude... if you NEED 400kw to overtake, your doing somthing wrong.

There's nothing you can't do on the street with 300kw that you can do with 400... other than taking down a Lambo or Mclaren. So what's the need to run a knife edge WMI tune on the street? Overtaking? Come on dude...

J.

^^^ how often do you get out past the town limits?? Do you feel threatened when you see insects on your screen, a bit jumpy at the thought of grass and tree's, can't get your head around lines of trucks and single lanes???

Go tell your idea's to the nearest R1/Fireblade/GSXR/Speed Triple/Hayabusa/Ducati etc etc etc and see what they all say, most big bikes have a power to weight ratio that dwarfs 400rwkw.

TBH I only have 300, and I use the WMI for controlling detonation, but I'll aiming for more and might make 400-450rwkw soon and I'll still want more - we always do.

And at the end of the day, once you have done and paid for your mods, driving a 400kw car isn't all that much more expensive than driving a 300kw car on the open road. If your cruisin' and not boosting all the time then your really driving a +2 litre in line 6, which is an economical car. Lets face it, the emphasis is on fun [in a driving responsibly sense].

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
