Firstly looking into getting meth, Which is the best kit on the market?

And what's the best way to control it as I currently use a accessport cobb?

Thanks

[BOOST3D]

Aquamist hfs4 is the best and most comparable with Cobb

[cwarren]

+1 hfs4 is the only way to go .

[Lawton438]

Where's best place to purchase? Anything else required?

Would a pro tune be alright with the aquamist kit?

[Allen@MOTIV]

We recommend(and carry) the Aquamist HFS4 system.

[Jeff@TopGearSolutions]

Aquamist is the best system but you can get it done with a cheaper system and upgrades.

For ease of buying and having everything in one shot just got aquamist.

I'm currently running a bov so would I be best just running water untill I got a new cp and diverter valves?

While there will be some discharge when the BOV pops there really isn't any realistic risk of fire from it. Most people running meth are using BOVs and I've personally been doing it for 2 1/2 years at 100% alcohol and no issues.

[Lawton438]

That's good to hear then as will save me buying another cp, how much can you do the aquamist kit shipped to the uk for?

Aquamist HFS-4 no question

[Chromey]

Ok I just ordered a ER FMIC and a ER charge pipe with one meth bung and a tial BoV... I had the option of a meth bung or a aqua it's meth bung.... Since it said it will not be capped I went with the capped version as I'm not getting meth till later next year after my warranty runs out. I may do very soon though knowing me. Did my choice eliminate aquamist

[maizer89]

how does hfs-4 fail safe integrate with the cobb? that's been my biggest question where I haven't gotten a good answer to. JB4/proceed can have the fail safe wire to immediately trigger safe mode, but haven't heard what cobb does.

[Chromey]

I'm curious too. Seems everyone running meth uses proceed or jb4.....

[idnan]

Since you're from the UK, you can order an Aquamist HFS-4 from here as they're based in Oxford.

The aquamist has it's own failsafe which wires into the boost solenoids and opens the wastegates fully in an event of poor meth flow.

Ok I am not sure the question is being fully answered here. I am still left wondering HOW exactly meth will failsafe to a tame map if meth stops flowing for any reason using HFS-4 and COBB? I called COBB in Austin and they said their AP does not have that failsafe map switching feature for meth, without that I would never run 20psi on my car with AP, bc if meth stops kaboom! This leaves only PROcede with aquamist flow sensor and failsafe map 4 or JB4 with FSB board failsafe. I prefer PROcede bc it uses an actual failsafe sensor.

Can anyone answer exactly how the AP failsafes to a low boost/timing map when meth stops flowing??

[proTUNING Freaks]

We recommend the Aquamist HFS4 and it is the only kit we've chosen to recommend and carry over the years due to its superior funcionality and quality combined with a trunk mounted tank. We've tuned countless N54s with meth injection on the Cobb platform over the years with consistently great results. If you google or search this and other forums you'll find plenty of examples. Let us know if we can help at all: support@protuningfreaks.com.

This was answered earlier.......I believe that the Aquamist kit reduces boost by dumping the vacuum to the boost control solenoids which in turn control the wastegates and boost pressure.

So the wastegates are thrown into an open position and the turbos will not build boost. In essence your car gets put into a limp mode.

No map switching available on a flash tune since there is only one map stored in the DME.

Since The procede is a piggy, it can store multiple maps and automatically switches to a safer map with lower boost and less timing advance in the event of meth flow interuption.

Shiv would argue that a timing reduction strategy is faster and more immediate since it is electronic rather than mechanical......using wastegates results in a bit of a delay before the turbines can wind down.

How much of a difference does it really make.....

Either way, if you start to exprience engine knock due to interupted meth flow, the DME is going to sense it and start to pull timing out anyways.

Since the vishnu pwm kit is built from aquamist hardware, the quality of the product is the same.

However, if you go with a Cobb tune you will not be able to integrate your PWM kit with it since it requires a stand alone aquamist controller.

In the final analysis....both systems have a failsafe and both work very well. At this point it's more about who is going to support your tuning.

IIma, thank you man, just the answer I was looking for!

Back from the dead but re the fact I got a ER charge pipe but didn't say for a aquamist meth bung what does that mean? As I want to order a aquamist kit ASAP. By the way who carries them now, topgear doesn't etc

When you order an ER charge pipe, unless you specifically select Aquamist bungs, it will come with standard 1/8 NPT threaded bungs.

This is not really an issue though as Aquamist sells adapters so you can keep the charge pipe you have.

I actually prefer people go this route because when you get Aquamist bungs from ER they do not come plugged so you are more or less forced to run meth if you want to install the charge pipe.

When you order the 1/8 NPT threaded bungs as standard they come plugged.

You can get the Aquamist kit direct from Howerton Engineering. We did in fact stop offering them as of recently.

The HFS4 kit does not directly integrate with the Cobb or its tune, unlike JB4/FSB. It just has good failsafes which you can wires into the wastegates to dump boost.
