Thread: Jetboil cut down...But Souped Up

  1. #1

    Default Jetboil cut down...But Souped Up

    So I did a write on my initial experiment with my modified jetboil setup the beginning of this summer. After using this to make freeze dried food for over 30 nights total in the field with it since using it in temps from 70 to 15 degrees I feel I can finally call it a success. Members Stid2677 and Whitepalm have seen in in action as well and were at least kind enough to lie that they were impressed with the setup as well. Overall its much improved over the original and I think this is mainly attributed to jetboil purposely retarding the burner output of the stock jetboil stove making for longer boil times as well as the stove design of the original jetboil stoves do not allow heat to be reflected off the bottom of the jetboil cup itself while cooking and back to the fuel canister making for longer boil times as the canister gets colder and colder with no heat reflecting back to it to help vaporize the gas. Whereas the SOTO stove does not have the same sheild around the burner that might prevent heat getting back to the burner in addition to the ability for the regulator of the stove to allow more a much more robust flame resulting in faster boil times, which means I can get hiking/hunting faster.

    Anyways here is my write up of my initial cutdown of the stove setup:

    So finally got around to getting my jetboil stove cut down and the notches cut in the bottom for the 3 pot supports of my new SOTO stove. The idea is that while the Jetboil stoves themselves are heavy compared to other canister stoves (they weight 7 oz) the jetboil fluxring I feel does make for improvments in boil times. So I figured why not combine an ultra-efficient canister stove (SOTO at 2.6 oz) with an efficient pot (jetboil pot).

    Decided to have my jetboil pot cut down at work as we have unlimited metal working tools to work with after hours and a guy there loves to do little projects like that and made look much better than the frankenstien I no doubt would have created. Heck he put a like OEM bevel back on the pot after he cut it down so the original lid fits on there once again. The new jetboilette is only 4" deep vs. the standard jetboil pot being 5.75" deep.

    Here is a pic of the two side by side of just the pot themselves:


    Anyways now back at home I decided to do a few weight comparisons.

    My naked jetboilette without/cozy/lid/or bottom cup comes to 4.4 oz. The orignal stripped the same way comes to 6.0 oz. The bottom cup weighs 1 oz even compared to the 1.3 oz lid. .3 oz isn't much so I'm sticking with the tighter fitting and more functional lid over using the bottom cup as a lid.

    I also had my wife remove the handle and cut the cozy to fit my jetboilette.

    So the total weight difference.

    The jetboilette with 110 gram snowpeak fuel canister brand new, plus the soto stove, and the sippy lid comes to 15.6 oz.

    The standard jetboil cup with the standard jetboil stove with the same fuel canister comes to 20.6 oz or a 5 oz weight savings overall.

    Here is the two being weighed in. The new bevel actual holds the lid on a little tighter even than the original bevel.

    Jetboilette all packed up:


    Orginal packed up:


    The Soto stove installed on a fuel canister is taller than a jetboil stove is but since the jetboilette is shorter the overall height of the smaller jetboil setup is slightly shorter. The notches cut out for the pot supports make the jetboil pot VERY secure (compared to your standard pot on these supports obviously not as secure as a jetboil locked into a jetboil stove). Though I still do have the option if desired to lock the original jetboil stove into the jetboilette.



    Now for the disclaimer:

    The follow tests were conducted by a person with absolutely ZERO scientific background and realizes that these test will more than likely be scrutinized heavily due to one or many factors that would render these tests of little to any actual real world meaning.

    All tests were done at room temperature with 500 mL (the fill to line) room temperature water.

    Room temperature fuel canisters boil times:

    Jetboil with jetboil stove:

    2 minutes 5 seconds.

    Jetboilette with Soto stove:

    1 minute 35 second.

    Last night I put two full fuel canisters in my freezer that was set at -10F.

    I quickly took the first out and screwed on the jetboil/jetboil setup and it boiled the 500 ML of water in 3:45 seconds.

    After that I took the 2nd freezer canister and screwed it onto the SOTO stove and fired it up. It boiled the 500 mL of water in 1 minute and 50 seconds.

    So the coldest canister did have some apparent affect on the SOTO's performance but not much from what I can tell. Where the jetboil/jetboil was nearly twice as long to get a boil and the flame was noticably smaller and quieter than the Soto with the cold fuel bottle where I couldn't notice or hear a difference between the room temp and the cold fuel bottle.

    Overall I'm VERY happy with my findings so far as my new setup that is both 25% smaller and 25% lighter and boil times are twice as fast in colder climates. I think this could be one of the most fuel efficient canister stove combos out there right now.

    Great post Luke, I can say that your stove was twice as fast as mine on our goat hunt. Great info.

    Nice post. Cold weather performance is the only thing I don't like about my Jetboil.

    Nice! Time to send your ideas to both Soto and Jet-boil and see if they can improve even further on the design. Maybe you can get some coin or gear out of the deal!

    good post,one thing i'd have too say is will it hold up over time,i've got a whisper lite that has been with me since they first came out,some what maintance free...anyhow it has to prove its self over time....light is not always a good thing,durability comes with a little price...

    Very good point Sheepman. Can't say for sure how long this setup will last. However, I don't feel it is in any way inferior to the standard jetboil setups that have been running since 2003. Time will tell. Everything is a trade off. I have a Whisper Lite as well that I have had for only a fraction of how long you have had yours no doubt as mine is only 10 years old.

    Never had an issue with canister stoves to date and for me they are lighter and boil water faster which is all I am looking to do for the most part. That said for true winter camping trips I bring the whisper lite, plus it also comes along at my basecamps on fly out hunts as a just incase, but never leaves where the plane drops me off. Everything is a compromise no doubt. Just find what works for your intended purposes and run with it.

    I am not the type of person who takes extreme care of his equitment,i guess i need bullet proof equitment,throw the whisper lite under 100 lbs of meat and she'll come up firing everytime.......jet boil would look like a smashed beer can after i get through a hunt....

    Not really sure about that. I have stepped on my jetboil pot a few times (yes I am clumsy) and it was no worse for the wear. No problem to sit 100 pounds of meat on top of the pot with the stove and fuel canister inside. That titanium cup is pretty robust if it can support my lard hiney a couple times thats what is so nice about the jetboil setup is that its all inclusive and the pot actually protects the stove. I don't baby my gear either however I do take care of it. But just because it can sit under 100 lbs of meat doesn't mean I would do it. I don't have any doubt that my swaro spotter could survive being packed under a bunch of meat, but I can't think of a situation that I would purposefully do so. Maybe I am just lucky that the jetboil setup hasn't broke yet and will do so next time out, I don't know but all I can say is as of now I am pretty satisfied.

    You must be burning the midnight oil as well huh

    looks like you have the perfect piece of equitment....

    HAHA...I don't think there is anything perfect about any of my gear. Just what I have found has worked best for my needs as of now. Always subject to change and fine tuning.

    Thats what so great about having a TON of options available to us hunters these days. Everyone gets to fine tune and tailor their equipment to what they feel works best for them as you very well know, being one of the guys that gets out there and gets it done more than most (myself included).

    Thanks for the kind words,just remember light is not always good....in your case it might be....there's lots of examples out there, kifaru packs to a barney's, like a gear junkie told me once you don't pull a horse trailer with a 1/2 ton truck, i have a lot of hunts under a barneys and only one under a kifaru,ya it's light but it won't hold up,just what you need when your on a 10 to 14 day hunt is the 1/2 ton truck breaking down on you. not saying the jet boil isn't perfect,just keep in mind durability.....one question how many days on a canister??? i'm pretty good with 22oz of white gas on most hunts,i always leave a extra bottle at the starting point just in case....

    Great points for sure. Light isn't always good otherwise I would hunt with my 4.5 pound 85 liter pack instead of my 9 lb one. Same with boots and many other things. But if you can save weight in certain places and not lose durability I see no reason to not take advantage of it. However, durability is one of those trial and error things no easy way around finding out how durable something is, just gotta use it until it quits

    As far as fuel goes, Whitepalm and I were able to share a 220 gram (12 oz gross weight) canister with this setup for a week long sheep hunt with some fuel to spare with quite a few extra boilings being pretty liberial with how much coffee we were drinking. One could easily go a week solo with just one 100 gram (7 oz gross) canister. The jetboil like every canister stove has inheret weaknesses associated with it compared to other types of stoves as well as inheret strenghts, its up to each of us to choose which weaknesses and strength we can live with to suit our needs.

    Now for the important question. Will the coffee press still fit with the cut down pot and SOTO stove?

    That is an impressive mod to save 5 oz. 'ette is probably tougher then the original with the new lip and dimensions.

    I don't know, I rock the starbuck vias exclusively for my coffee when backpacking, but I am not very picky when it comes to coffee at all. Judging by your screen name I have a feeling your coffee standards may be a bit higher.

    Or you could just go to the bathroom before departing... Just sayin'

    (reference is actually toward snowmachiners who will spend $300 replacing all their suspension bolts with titanium in order to save like 8oz of "sprung weight" )

    Anyway... I love my JetBoil and I love the Starbucks Via packets. The two of them, together in harmony, make for a great morning in the woods!

    Out of curiousity, do you have a standard ultralight titanium backpacking pot to compare to on the SOTO. Just to see how much the flux ring speeds things up on the SOTO?

    I probably can find one. If nothing else I can get my 600 mL snowpeak cup and see how fast it boils the 500 ml.

    That would probably be close enough of a comparison..

    It's just something I've always been curious of.. Always wanted to see how much faster the flux ring really is.. but comparing them on 2 separate stoves just didn't seem fair, because the MSR was boiling water just as fast as the jetboil, as far as I could tell anyway. I didn't have a thermometer in the water and a stop watch or anything that serious.
