I'm boosting 18 psi, combined with a simple Cooling Mist On/Off Basic kit which flows 900 ml/min through a CM10-nozzle.

I've set the boost switch to activate the pump at 7 psi, and the car is awesome.
No bog, no hesitation, no lag and no strange behaviors AT ALL.
The car is also really sweet during light- and half throttle-driving when I'm cruising to the school with my kids or going to the supermarket.

My car is both fast and consistent, despite of this "simple" system. Thats it.

I'm not sure if there's any meaning to make it more complicated than it need to be...?
There's definitely more components/software that may cause trouble.

Just my 2c.

Do you know why? Give you a hint, running pressure is a function between the by-pass valve setting, flow capacity and flow demand.

In other words, the one that set to a higher pressure will drop faster as flow demand increases. The pressure of 150 psi pump will drop much slower until the flow demand/pressure is approach its rated capacity.

Why did you pick this topic to discuss without any basic knowledge of how a pump works.

Vishnu/aquamist has chosen to run at 160psi so the pressure across the entire delivery range is more constant rather set the pressure to 200psi+ and expect a large drop as flow demand increases.

There are other reasons such as managing temperature rise of the pump at higher pressure. Higher pressure requires more electrical current. You may or may not know this, power dissipation is proportional to the square of current (I^2 R) increase. The other reason is undue stress to the pump seals and bearings.

Vishnu/aquamist has taken the route to enure the system is reliable long term, until you offer your system for sale to the public, you may think differently.

This will be my last post on this thread. Clap, you may be trapped in your over-inflated ego and limited knowledge, but step out a bit and learn from others. pwm@vishnu.

You are so clueless it is almost sad that you are a vendor.
Anybody with half a brain will realize that the higher rated pump will be able to push more pressure on bigger nozzles. Give up buddy.
You might be trapped in your own stupidity. All bark and no bite
No proof of anything, no data for anything. useless.

agreed 100%, I'm on the same boat of yours, ITS ALL about spraying the damn meth in the intake manifold. I don't understand why it needs to be complicated, its just marketing I suppose.

Finally People saying what I've been saying since this thing came out. On many other platforms I could find value in such a kit... But not this one.

...and that is what Clap is trying to say.

Anyone that's been here for a while should understand that as good of a tuner that Shiv is, he is even better at marketing. This is how a product is released by Vishnu:

1. Hint at upcoming feature/product in existing threads.
2. Create thread dedicated to feature/product and write an essay how it will do marvelous things for our cars (ensued by mass euphoria and hysteria...look at the fuel upgrade threads for an example).
3. Release feature/sell product.
4. Remove feature from latest maps/firmware or replace product with supposedly better and more expensive version.

How come no N54 records are being set by a Procede-tuned car with the following features: Launch Control, Autotune, Spark Timing-based Traction Control, Nitrous, Dynamic Ignition Correction, etc.? Each of these features was supposed to make our cars better and faster. Am I the only one that finds it funny how most of these aren't even available and even the latest firmware gives you the possibility of running without DIC. How surprising...

...and then we had the recent Fuel System Research threads. It was just like all of the rest. Theory and Marketing.

You really dont know when to quit. I don't know if you know this but the pump used in our 160psi application is THE SAME pump as what is used in 200psi PPS applications (coolingmist, AEM, Labonte). There is no higher rated pump. At the same input voltage, both a 160psi Aquatec pump and a 200psi Aquatec pump will spin at the same speed. What dictates their pressure setting is the spring rate in the bypass valve which is located in the pump head. Please don't hit the reply button and read that a couple of times.

I don't think any of us here needs to post proof of this. Or evidence that the pump that is running in a higher pressure system will be the first to drop pressure as meth injection rate increases beyond it's capacity.

The meth nozzles indicate the leak in the system. It does not define the operation pressure. Now that you understand this (hopefully), please dont change the subject or deflect this. This song and dance is old.

Apparantly you aren't reading up either, I never said I have any loyalties to any company. I've tried the Jb and if something comes out that I like more than the procede, I'll be switching again. I was actually considering the Cobb unit for a bit, but I have an 07, and would like to see where the AP goes for this platform before I commit to anything.

My reading compreshension is just fine. Let ask again- are you or are you not running a Procede Tune? Don't give me this "it's V4 not V5" crap. That's so simple.

The implication you made is that Clap was tune bashing based on vendor and sucking up to Cobb; Someone else alludes to the fact that you run a Procede and are doing the same- which you categorically deny above. Of course, you are then vindicated when it's revealed you are an innocent victim running a JB4.....Oh....Wait....

I never said anything about loyalty- but it's ridiculous that becasue you run V4 it's not considered a Procede tune...If you're still confused- read what you posted into perpetuity on the interwebs.....

So I ask- who's the douche again?

Hey clap I think I live pretty close to you(long island). Im supposed to be one of the first to recieve the pwm meth kits this month. Id love to do some testing of it and have you take a look. We can post up logs and do a write up on it also.

Sure, pm me when you are ready and well try to set something up. I go to a bunch of dyno days with some old buddies and one should be comming up in the next 2-3 months. NRG ever heard of them?

I agree a 100% with Mr.Clap, my father and I have been tuning for years now, and PWM is worthless on n54 IMHO

Yes, I currently have a procede, but what you continue to miss is the point I was making. I RAN a Jb3, but you don't see me creating threads bashing on all of the newer Jb products now that I'm running a procede tune. You also won't see me bashing procede products when I inevitably move on to somethingelse later on. What clap is doing is exactly that, and making himself look bad. Agree with me or not, but he certainly hasn't been acting like a mature adult.

Dude. Sorry to come in to state the obvious (to everyone else but you, that is). But you haven't contributed ANYTHING technical at all to this discussion in the 20 posts you've made in this thread.

Just stay out of it for cryin' out loud. You're only clogging up the thread.
