Manifold Cooking

[60seriesguy]

There are two things I never saw on expedition in South America: onboard hot-water showers, and manifold cookers. Both initially struck me as gadgets, but the first time I had a chance to take a hot shower in 40 degree weather after two days of four-wheeling (couldn't stand my own smell), I was sold on the first. Then a few years ago, on another trail ride in the snow, we took a short lunch break only to see a guy whip out two very hot foil-wrapped steak burritos from somewhere inside his engine compartment and start to eat, while we waited to use a stove to heat up our lunch. I was intrigued, and since then I've seen several different setups.

Last September, as a birthday present, my wife bought me a manifold cooker which is a step above the homemade ones I'd seen. This is the first chance I had to install it, which was a cinch on the square manifold of the 4BT (plus there was plenty of room). I'm *psyched*, can't wait to fire up some PopTarts to test it out!

The next step is to re-install the onboard shower on the new engine, maybe next week....

Anyway, here's a couple of pictures of the setup. The base mounts permanently on the manifold, the container itself snaps into place. It's hard to see the size but I calculate it will hold an 8-pack of hot dogs.

[Scott Brady]

HA! That is fantastic...

I have been a manifold chef for over ten years, and always get a kick out doing it. The Jeep I6 is practically built for two burritos, so no modification is required. The Tacoma has room for them, but the engine runs so cool (and is aluminum) that it doesn't quite "cook" enough. I will need to investigate some options.

On my Trooper, I built a little cooker over the exhaust manifold. I call it my burrito bucket :eatchicke

[The BN Guy]

Pretty sweet invention! Beats just laying something up there and hoping it doesn't slide off. Gotta figure something out for my V6 and the overhead intake manifold.

[chet]

my dad has a few off hiway logging trucks and they all have a large (because they have the room) basket on the manifold. Two sections one for cooking and one for heating. when you are miles from nowhere in the snow and cold a hot lunch is a big deal. We have put a can of beans or chili in the cooker side and a few burritoes in the warmer section.

It was funny because the one cooker busted off on a truck and no one wanted to drive it! The last guy into work got that truck! haha cold lunch for you! :coffee:

[Scenic WonderRunner]

OK..........60seriesguy....!

Looks Great!:chowtime:

Now you need to come up with a manifold recipe book for us.......showing how many miles per 1 pound burrito!.....etc!:eatchicke

OH NO!...............now what do us Downey Header guys do>?!!:rolleyes:

Best quote from the synopsis of Manifold Destiny:

They may even change the way people select new cars: the Chevrolet Celebrity GL offers six servings, while the Camry has only three but sports a bun warmer, a feature seldom mentioned in Toyota ads.

I wonder where that bun warmer is on our rigs?

[Brian McVickers]

Do you need to be concerned with fumes from the engine while doing this?

[goodtimes]

I'm curious....how many people actually "cook" on their manifolds? I usually reheat something that I have cooked at home (sloppy joes, burrito's, fried chicken, etc). I generally just stuff "whatever" on top of the injector rail. I had a burrito up there when I went through Hiway to Hell a month or so ago, and if that trail doesn't knock it off, not much will. I have never had anything fall off the injector rail. There really isn't much room for a "burrito bucket" on the new jeeps as the exhaust manifold is hidden under a bunch of crap....but the injector rail works really well.

So, who "cooks", and who "reheats"?

[goodtimes]

Do you need to be concerned with fumes from the engine while doing this?

No concerns about CO....all the "bad stuff" is heading out through the tail pipe, not into the engine compartment. Even if it does (like when you have an exhaust leak), CO is a gas that is not going to condense onto your food, and poison you. If you had a bad exhaust leak, I certaily wouldn't stuff my head under the hood for extended periods taking nice deep breaths with the engine running...but it isn't going to hurt your food.

[Steve Curren]

I was wondering if I could find the size of the fixture that was put on by 60seriesguy? I found the item and was going to see if it would fit in my TJ, cooking like that sure sounds like the way to go.

I am planning on putting a 4BT in my series rover. More engine pics, please...

[ZooJunkie]

Here's the link to the Hotdogger IV.

Thanks for posting your toy! I've been wanting to do something similar for my Zoo.

[0utback]

Haha! I do this all the time.

It still amazes my Jeep buddies when during a winter or cool spring / fall run I open the hood at lunch break and whip out 4 toasty Pizza Pops, a couple of burritos or egg rolls, hot dogs, or something. Meanwhile the rest of them are standing there eating cold sandwiches or subs. In fact, they almost expect it of me now and I usually get the question posed... "so what are ya cookin today?"

I would just like to now if I decide to heat a can of soup or beans or chili if it will explode and make a mess under the hood, or if it would be safe to try?

[bh4rnnr]

So most of the club has been using what is now called the "Snackster" in honor of the creator, Tim Nakari. Uncle Ben once called him "Snack Man" and the name stuck. Tim found a deep frier/grill type thing at Home Depote. Cost 10$. Cooked many goodies on it. Tim has cooked on or two roast, think one of them for Cruise Moab. I had some steak on there for one run, the forest service ranger riding along could tell it was done:chowtime: . For the low cost, it works awesome. I'll try and find some pics. Matt, post up if you beet me to it.

[xcmountain80]

When I was traveling around with my buddy doing the 24 Hour solo's we would heat food on the manifold, headers, and muffler depending on the model of rental vehicle.

MD has become a cult classic. Too bad it's out of print. A freind of mine gave me a copy for Xmas one year a long time ago. I dig it out once in a while & swear I'm going to try one of the recipes. Maybe this time it will stick.....

[decartwright]

I remember instructions (I think) in a Boy Scout pamphlet, 40yrs ago about how to fold foil to seal in what ever you wanted to cook. We used to split up a pound of ground cow between 3-4 guys, cut-up a couple of spuds, carrots, onions etc. with salt and pepper, seal it up and pitch it on the intake of a V8 and head down the road. The 55mph slow cooker.

[adventureduo]

Question to all you manifold cooker gurus.... i just installed a rotisserie fish basket in my engine bay... and i was wondering.. do you really think it needs a lid or a top? Reason why i ask is that the basket barely fits in the header side of the engine bay and i think the basket top/lid won't fit properly. Wondering if i even need it? I mean.. shoot won't i have to jump the truck to get the food to fly out?

[bucketosudz]

I have now seen it all!! Manifold Cooking?!? Seriously.... I LOVE the Portal. :wings:

[CanuckMariner]

I too have cooked on my manifolds, but not with any gadgets, however they are quite unique and handy. My method began with HD tin/AL foil and doubling it just in case.

Depending on what you cook, say beef stew: put your one or two portions of cut stewing beef (as much as you want to eat at one sitting). Add veggies (carrots, potatoes, etc. - the smaller you cut them the faster they cook, so keep this in mind while you are making the meal and how long you will be driving) and then salt and pepper to suit your tastes, some onions, etc. and lastly some butter to melt to the bottom to keep things from sticking and make some of the gravy. I can usually judge the amounts and sizes pretty good to suit a 3-4 hour drive or as long as 8-10 hrs.

Nice part is, no cooking when you get to the camp site, just set up and begin eating.

I use coat hangars to hold the foiled wrap next to the header nice and snug. I double fold all joints and roll them so no leakage and if the pressure rises a bit, it will still find a way out with out bursting the seams.

Of course your engine, ahem, your stove size has to be considered and how hot it gets. Diesels do well with manifold cooking.

[CanuckMariner]

BTW, your ARB compressor might get a bit warm installed where it is near the manifold, just a thought?

[John E]

in another lifetime I was a newspaper photographer, I can remember doing a story with a reporter about this very topic. She had a copy of the Manifold Destiny that she used for some recipes and we used her truck for the cooking.

The only problem was that the truck didn't get hot enough! It was a retired CA state Dept. of Forestry fire crew truck that apparently had a very serious cooling system.

It was a fun little assignment, food was ok but nothing to write home about to be honest but that was more about the writer and the specific truck than it was about the general idea.

Here's my version.... it's a fish rotisserie basket for a BBQ.

Going to try some breakfast hot pockets on the way to the meet and greet saturday :D

[CanuckMariner]

Dave, that will certainly heat them up but don't count on any cooking in the basket. Manifold cooking works partially by circulatory/convection heat but mostly by conductive heat.

[adventureduo]

Whatever goes into the basket gets wrapped and covered in foil.. just like many i've seen... you're saying that's not going to work? I've seen stew cooked this way after 8 hours of driving.

[zukrider]

i think what he is saying is that the gap you have between the manifold and basket wont quite do the job. but i think it depends on what your cooking and how long its in their.

[adventureduo]

Gotcha, it's only a few inches from the header.. so we'll see. I can't fit the basket any other way. If it doesn't work i'll cut the basket and weld it back together so it's not as wide and then that way i can get it closer down into the header area.

I will know saturday if i need to change it.

[CanuckMariner]

...you're saying that's not going to work? I've seen stew cooked this way after 8 hours of driving.


i think what he is saying is that the gap you have between the manifold and basket wont quite do the job. but i think it depends on what your cooking and how long its in their.

zukrider said it right on, the gap may prevent enough heat to cook anything. Although it will warm up things nicely or thaw frozen items easily.

I cook stew all the time and with double HD foil around it, folded joints and tightly wired to the manifold it cooks easily on my diesel 1HZ. However, diesels are known to be a bit warmer than gas engines. Happy cooking, hope it works out.

[DarinM]

I just got Manifold Destiny and read it yesterday. More commentary than recipes but it was a very enjoyable read. I think it provides some good ideas for getting into the idea of engine cooking and I'm looking forward to giving it a try one of these days.
The commentary ranged from LOL to LMAO, but YMMV. I give the book :chowtime: a hungry guy and two :26_7_2::26_7_2: thumbs up!

And no, it didn't stick.

[dustboy]

The OP mentioned on-board hot water..What about wrapping some copper tube around the manifold and circulating water from a tank?

[adventureduo]

Well, we cooked a little in Death Valley. On the way out we cooked 2 corn on the cobs and 1 hot pocket. After the 5 hour drive they were perfect. The corn was super tasty and steamed perfect. Left the husk on. The next day we headed to the race track and cooked for another 3 hours... hot pockets again and some brats. The brats did not cook. So i guess with our particular basket we need to cook microwavable foods :D It doesn't get hot enough to grill or cook meat.

[Desert Dan]

I bet the brats were tenderized after the Race Track Rd!

[adventureduo]

Yeah they were! LOL

They were under the hood from 9am-6pm all day on the trail... still undercooked and nasty when we got back. Warm though :D

[Maximus Ram]

So after reading this thread and seeing the hotdooger, I did a search for cookers. This one seems to be a bit bigger than the hotdogger and has an interesting name

Looking at this one, IMHO I think the closer you can get (right on top of it) to the manifold, the better it is. More heat there. Temp drops considerably from the manifold back as the metal heat transfers and there is more air circulating while driving.

[ntsqd]

What I dimly recall from thermodynamics is that like a lot of things, heat energy varies with the inverse of the square of the distance. So 2X further away = 4X less heat energy and 4X further away = 16X less heat energy.

That looks interesting. My FJ80 is at the fab shop right now getting a mild makeover- rear tire/ can carrier, skids, fairlead mod and a custom manifold cooker. I'll let you know how it turns out after the tests. :chef:

Dave, do you happen to have a pic of your cooker you could post? My experience cooking on the Jeep motor was the same as you- burritos etc but no raw meat.

[pkelly72]

I've got headers and they get HOT. Do you think this would be a problem? I'm sure I could cook something with that much heat.

[luk4mud]

OK, we gave my new manifold box a good workout this last weekend on Mohave Road.

Friday: burritos (5 or 6)
Saturday: corn dogs (4), roasted garlic/ rosemary potatoes
Sunday: hot dogs (10), leftover bbq beef, burrito

It cooks/ warms a little hot on the bottom, so I need to work on that. maybe a small internal heat shield or something. Otherwise, it works great.

I bought some of those little foil takeout- style containers from Smart and Final, I'm gonna try soup or chili next.

Then I'll start working on the cookbook ...

[adventureduo]

Right on dude. I need to get down there and have Octavio make me one.

Any other "better" photos besides the ones he posted on mud?

[luk4mud]

Nathan got a few good ones, should be up on his site soon.

Let me know what you come up with. We were out of town this past weekend and tried some hot pockets. Wrapped them up in foil and had them stuffed for about 2 hours. Kind of between the firewall and back of the intake. I would have gotten it closer to the heat but there are a lot of hoses back there. I'm thinking the best spot is on top of the intake near the diagonsis box and engine hook.

[luk4mud]

Update- took the LC to Cal City yesterday riding dirt bikes. Stopped in Palmdale, about 1 hour out, to put lunch in the new EZ bake oven- frozen fully cooked turkey meatballs in red sauce, steamed veggies, corn on the cob, potato wedges, corndogs for the kids.

Arrived, set up our site, rode for an hour or so and came back for lunch. With the exception of the potato wedges, everything was deeeelicious.:victory:

The trick seems to be to gauge cook times by miles and engine temp. It's real easy to overcook stuff in there. Containers make a difference as well. The rigid but disposable tin foil contaners (think take out) work real well. Meat without sauce placed directly on the box surface tends to boil/ roast.

So, I'm getting there. I have recipes for margarita shrimp (45 miles only) and pork tenderloin (250 miles) I want to try next. Cook book available in stores near you soon.

I'm hemorrhaging money for some reason and my bank ship is sinking. While a cheap mod I'm afraid I might have to add this to my Christmas list. I will try and mount mine on top of the Header for best results.

I wonder where that bun warmer is on our rigs?

Electric seats.

[oryxexpeditions]

I used to be a chauffeur for the MGM hotel in Vegas, a long time ago now, and had a friend who used to heat his left overs up on the limo engine while he was waiting for a call. Anyway, he was warming last night's fried chicken up one day when a call came in to get to the front quick to pick up guests to go the airport. However, in his hurry to get to the front door, he forgot about the chicken on the manifold . . . About halfway to the airport, one of the guests asked where the smell of fried chicken was coming from . . . ::Wow1:

Never tried a hotdogger on a bike, but i cant see why it wouldn't work! We used them on our sleds all the time. As long as you can find a spot on the exhaust that will fit it your good to go! The muffler might not get quite as hot on a bike since its farther from the motor than the pipes on a sled, so you might have to cook them for a bit longer.

They also make a unit that straps a can to your muffler. (super easy to build yourself BTW) Nothing beats a can of hot chili and some sausage dogs on a cold day in the mountains. Haven't ridden sleds in awhile but still have the hotdogger.......ought to strap it on the jeep and go for a drive :bike_rider:

[Hill, Bill E.]

Yep, nothing like some hot food for lunch or dinner!

Other than hot dogs wrapped in foil, and those store bought burritos, I'm more of a 'Reheater' than a 'cooker'

I did try to cook porkchop once, but I don't think I left it on long enough.:snorkel:

[1911]

F and 2F-engine Land Cruisers have a great built-in manifold kitchen, a flat plate with upturned edges that sits right on top of the manifolds. Holds two or more burritos easily, and they don't fall off while you're wheeling before lunch. :chef:

The 3FE has too much emissions crap on it to be useful as a kitchen.

That is the perfect spot! I am gonna have to copy your set up. (if thats ok of course) A piece of exhaust tube a scrap of angle iron, simple yet effective!

So do sealed cans explode?

We usually took a nail and poked a hole that just barely pierced the can. The hole is just big enough to equalize the pressure but not really big enough to let the contents spill out of the can.

[Ala5ka]

in Alaska we use something called the "hotdogger" that attaches to your snowmachine exhaust and cooks hot dogs and such, they also make a pressure cooker variant for soup

Yep.

My engine is pretty much oil leak free. Just wondered if the food would have some off taste as it not a new truck that for sure. Looks like a bit of trial and error would be needed to see how long it takes to warm up the food. For me I would like to have some sort of air tight box just so I'm not eating oil smoked food. Like posted above (can of xxx)

[DreamingOfExpeditions]

A couple of quick engineering notes to aid your discussion!

Heat transfer is accomplished through 4 principles: Convection, conduction, radiation and Mass Transfer. Your purposes only need the first three. Radiation decrease by the square of distance. For the cooking your talking about, convection is the most powerful in the engine compartment.

Cans can easily be heated to 100-150C, as the retort process generally takes the cans that high. Thats what the accordion "bellows" are for on a can.

Carbon Monoxide used to be used regularly in meat processing. Ever get hamburger that was bright red on the outside but grey on the inside? The stuck it in a CO chamber to freshen it up. Used to be pretty common. So I wouldn't worry about that.

[Hill, Bill E.]

So do sealed cans explode?

I've only exploded 1 can, a can of Spahgettios:Wow1:

But that in Cali, in the summer, after a (slow) 9 hour convoy.

I had a similar set up as I posted of my CJ, but in my 5 Ton 'Bobtail'.

It sure made a mess under the hood!

I think it was becuase we were moving so slow, and that big deisel engine got pretty hot under the hood.:snorkel:

[ccarm]

It seems like you could have an entire weekends worth of food made just off the manifold. Burritos, Tacos, anything canned. I have to try this out on my next trip. Great ideas everyone.

[RichardAllen]

Sorry to introduce a limey element to this very interesting thread, but have any of you guys put any kind of cooker under the bonnet (hood ?) of a Land Rover defender with a 300TDi engine ?

I cobbled mine together from various parts. It sits on the coolant return line on a 6.2 diesel and gets hot. Works great.
