Let us know I thought about it too!! Just curious how much it cost to get a bottle refilled

Sent from my SM-G900V using Mustang Evolution mobile app
So i went ahead and did the math on this, because these are the kinds of things that will end up keeping me up at night.

For the sake of keeping things incredibly basic, i am comparing the cost of nitrous to ONLY the base procharger kit. You will likely need additional items, but i am only considering the base cost of the kit:

Base kit with forum discount: $5,475

Now nitrous is a little more tricky because of all the options. I am seeing prices go for around $700-$800 for single nozzle systems with WOT switches and window switches, so i will just call it $750. As far as refills, it looks like it just depends on shop and part of the country, i'm seeing prices reported anywhere from $3 a pound to $8 a pound -_- useless. I'll just run the math a few different times, its easy enough.

So when we consider the cost of nitrous is y= 30x + 750 ($3 a pound for 10 lbs + base cost of kit) and set that equal to y = $5,475 for the base procharger kit you get x = 157 bottles of nitrous before you break even. This of course is assuming perfect draining and perfect filling and exactly 10 lbs of nitrous each time. I can tell you that its likely not the case, and you will never get perfect filling / draining, but i cant tell you by how much. Here's a few different scenarios depending on cost:

$3 / lb = 157 bottles.
$4 / lb = 118 bottles.
$5 / lb = 94.5 bottles
$6 / lb = 78.75 bottles
$7 / lb = 67.5 bottles
$8 / lb = 59 bottles

Now, as far as how long a bottle lasts, i found a NX calculator that basically states you'll use about .8lbs per 100 hp (sprayed) per 10 seconds. So lets assume a bolt on 3.7 with a 100 shot is making around 400 whp and running about 12 seconds flat. If you're running a 12 second pass, thats 20% more than the 10 seconds in the calculator, so multiply .8 * 1.2 and you get about .96 lbs of nitrous used per pass. Take that number applied to our number of bottles and you'll basically get the number of passes to break even:

$3 / lb = 157 bottles. / .96 = ~163.5 12 second passes
$4 / lb = 118 bottles. / .96 = ~123 12 second passes
$5 / lb = 94.5 bottles / .96 = 98.5 12 second passes
$6 / lb = 78.75 bottles / .96 = 82 12 second passes
$7 / lb = 67.5 bottles / .96 = 70 12 second passes
$8 / lb = 59 bottles / .96 = 61 12 second passes

Depending on the cost of nitrous in your area, the procharger very quickly becomes an appealing option, granted the cost is much higher up front. I'm fairly certain my math is all right, but i laid it out in case people want to check my numbers or run it a few different ways (quicker 1/4 times, larger shots, different FI options, etc). If i made any mistakes please let me know.

You need to find a day job lol usually a 10 pound bottle is around 40-45 dollars. "Usually" lol

Turbo if you like looking at the car on jack stands.

Pro if you like looking at other cars in the rearview.

Lol I opened this thread just to see the "upgrade to a GT" comment. But I vote one for twin turbo. Your looking at about 6500 for jmp base kit.

You get it now don't you Kevin, welcome to the dark side. Nice car BTW.
Yes. After driving my 3.7 for awhile and it having a ton of mods, it only took 1 drive in the 5.0 to realize how big of a power gap there still is between the two. And that was with driving a stock 5.0.

And thanks for the compliment. I am still pinching myself to make sure this is real. :)

I think what he is trying to say is that if you go with a turbo your car will seem to always have something wrong do to the complexity of a turbo system. While if you went with a procharger you will instead have a more reliable and a lot faster car than you do now.

Personally my choice would be procharger, but thats just me.

This.

I said nothing about NOS, which is a good option in my opinion if you aren't going to race it often, otherwise it'll get real expensive real quick.

If this car is your daily, SC or NOS would be my choice hands down.

If you have another vehicle to get to work, then a vacuum leak or a bearing issue wouldn't be as back breaking.

NOS is the ricer term for nitrous - NOS is a company that makes a kit (Nitrous Oxide Systems), just like Zex, Nitrous Express, etc. So I don't know that NOS is any more likely to cause issues than any other kit if it isn't set up properly.

Nitrous is great, just get a proper tune for it. The only drawback is the ongoing cost of filling the bottle. You also will need a heater - cool evenings and early spring or late fall racing will hurt performance because you can't keep the bottle pressure up. And nitrous is a track only power adder. You can't keep it hooked up and on all the time because the pressure will wear on your solenoids. So it isn't like a supercharger or turbo where you have power on demand at all times.

Also, you need a window switch to control the nitrous. Start flowing too early and low in the rpm and you will have problems; don't rely on the switches that are supposed to read when you are at WOT before firing. I had that on my 2006, and at the track lining up pulling into the staging beams the system decided that 1,800 rpm was WOT and fired making the car jump ahead very quickly. I was lucky enough that time to lift quickly.

The window switch will stop the system from seeing anything as far as a signal until you reach your pre-determined rpm "window" to open the system.
