Looking for a Meth gauge solution

I need a guage with these requirements:

52mm
Electric with sensor
reads up to 300-350 PSI
Sensor is Meth compatible.

Discuss options, I do not want a mechanical gauge like you would see on a oxygen tank.

 

Do you mean 300-350 cc/min? None of the pumps run 300-350psi (that I'm aware of). I was warned by Cooling Mist that going beyond their set point of 200psi was no bueno. And they use the Aquatec DDP5800, like many other popular kits.

 

The Devils own pump is advertised at 300psi. But they ship it set at 200 psi which makes me wonder. They use that same pump number you listed but the head could be different.

In any event being able to read up to 400 is just nice and back to the topic i think i find something that will work. I was on the phone with prosport trying to find a solution and we came up with using a nitrous pressure gauge. this can read from 0 -1600 psi but it's made by glowshift. Prosport does not offer one.

I am not sure if the sensor with meth compatible so i am working on finding this out. Even if my max pressure is only 150 i want to be able to see what my pump is doing. This nitrous gauge reading at 0 and up makes it versitile

Yeah, I've seen that. I'm of the opinion that it's misleading. Technically that Aquatec pump can be set all the way up to 300psi. That's the same for every company that uses it (AFAIK). But it's not good for it. Think of it like running the maximum boost possible all the time from whatever turbo you have. It'll cause early failure.

 

Just my 2 cents but i turned my pump(d.o) up to 300 psi when i installed it. Been running this way for 2+ years now

 

Sounds like you have good luck. Cooling Mist put the fear of God into me about doing that when I asked about it being a viable alternative to getting a larger nozzle. Justin (from FREEKTUNE) also said that he tried it, but it didn't lower his IDCs and that he didn't recommend it. Did it lower your IDCs? And how do you know that it's at 300psi; how did you measure?

 

Its not supposed to lower IDC, that is not the purpose of a meth kit and that is not the purpose of increasing the pressure. While you might get more flow from higher pressure that is not what I am chasing. Let me frame it up for you, I have a D10 installed and a D14 on standby which spray a metric ton of meth, but I am worried about atomizing not flow. I can get bigger nozzles for more flow if needed. Back before 5th port and 6th port and 8 injectors people were trying everything possible to lower IDC, so this was likely just a test to see the effect of pump PSI on IDC which I am sure was not much different. Perhaps on a larger nozzle the psi would have a larger flow effect (not sure what size was tested).

Unfortunately I do not have a tuner on my side to help me so I will have to do what I think is right. I would love to get tuned, but I do it myself to the best of my ability. I have trouble with the idea of someone else tuning me as they want to charge for each iteration and I change setups all the time, the weather changes, many things change and they are not going to be available for free to help me every time something goes wrong. I have contacted some tuners and they have set pricing for a very specific type of car which is lightly modded bolt ons. A car like mine which has every mod possible and everything that makes it complicated like a larger maf and meth and everything else they want stupid amounts of money to tune a car like mine and then its a one time deal. I don't have money to invest in a one time deal.

With all of that said I don't blame them for charging what they do and how they do it, time is money, and I also know that some people get better treatment and service with ongoing tuning, but I am not willing to take this chance and shell out money and be no where good. So yeah I approached some people and I did not feel safe with the answers I received and decided to stick to myself.

I know all of this about tuning is off topic (and very random), but when you mention Justin it just reminded me about how I feel about using a tuner and my concerns with doing so. I see people with good results, but my car is not that far off and I don't want to pay 500$ to be where I want to be one time only =(

-> Back to the pump. Cooling mist and other companies do not offer a SS Braided line option or NPT fittings, but DO does, so I think this could suggest a different pump head than the other companies. What is your take on this ?

 

People have different goals for meth. One of mine was IDC relief, because I was right at the threshold where when it'd get cold I'd start getting into the 100s. Since adding the methanol, My IDCs dropped, on average, about 7 points with a CM7 and 100%. That was one of my goals, and I'm glad it worked (and not surprised at all--I am, after all, adding extra fuel). My other goals were cooling (more consistent year-round performance), cleaning for the valves, and an extra layer of safety by cooling the combustion chamber, extra octane, etc.

I experimented with turning up the pump pressure and saw no extra methanol flow. My understanding of the reasoning why is because it's the bypass pressure, not the pump output. The pump flows what it flows, my Cooling Mist, for instance, is 1.3 GPH. I also say this by measure of my IDCs: they didn't change. I can see the logic in turning up pressure if you're flowing a crapton of methanol to keep good atomization. IIRC, most nozzles atomize perfectly fine at anything over 100psi. But if you're not seeing lower IDCs too, you're likely not getting any more functional pressure. This graph from Aquamist shows this:



I definitely understand about the cost of tuning. That's part of the reason I self-tuned for a very long time before finally going pro. You know, there are lower-cost options out there from very reputable guys like Purple Drank and Dizzy. My advice would be just to settle on a setup and get the tune done at that point. If you're constantly changing hard parts, it can definitely get expensive. But there's nothing quite like knowing you're tuned by an expert on our platform.

 

I use meth for the same reason I just want the safety from it, I am using a D10 for the extra fuel and cooling, but I dont expect it to be enough fuel to carry me up to or past 500 HP, maybe it is maybe it is not, I also have a D14 if needed.

I am happy to say though I made a contact and ended up talking with Dizzy and I am going to have him tune my car and I am excited to share the results soon. Here is a basic mod list of my car.

Mods: Wiseco 9:5:1 Forged Pistons, Pauter Forged Rods,ARP Main Studs, Devils Own Meth Kit D10, Garret 3076R T3/V-Band, Custom Air to water IC kit, CP-E CDFP, Cobb AP, Custom power wires batt in trunk, CP-E 3.5 Maf housing on custom Intake pipe, Custom T3 Manifold w/38MM Tial EWG, Custom V-Band DP, Borla Catback, Fidanza 11LB Flywheel, Spec 3+ Clutch, SU rear and front mount, JBR TMM, PTP BSD-Windage Tray, PTFE Mani Spacer, Kenne Bell Boost a Spark Ign Amp, Stock NGK Plugs at around .026 - .028 (I dont mess with Denso, bad experiences with constant fouling), I think I am running OEM head gasket with SP63 Head bolts H11 or whatever (not their first batch the second from A1 technologies), K and N filter with black hole style vortex for smoothing air and I added honeycomb in the vortex opening before maf, I have inline oil filter before turbo with restrictor with a pressure gauge sensor after that to monitor, AEM Oil Press Gauge, AEM AFR UEGO Gauge, of course a boost gauge, and glowshift EGT gauge, also looking into a nitrous gauge to read my methanol pressure (digital reads 0-1600 PSI) waiting to find out if the sensor will handle meth. PTP 1950 PSI Pressure relief valve or maybes its 2150 I cant remember, DCR VVT

 

A local buddy (@Mikey) had to go to a CM14 to hit 500whp. He has a built motor and an HTA3076. You should be able to get well into the 400s with the D10, I'd imagine. Post up logs and VDynos so we can follow along!

 

I will post all about it in Dizzy's tuning section as we progress. So far the guy has been more than helpful and willing to talk to me which is customer service with a great attitude. I think this is almost more important than tuning skills so we are already in a good direction. Updates to come.
