Gas turbine BBQ

Post by Johansson » Wed Apr 09, 2008 5:37 pm

While waiting for a suitable workshop where I can house my tools in the city I live in now I will have to put the pocketbike project on hold, but I still think I can manage to pull off a less advanced project in the place I rent at the moment.

I have a spare turbocharger from my motorcycle build that could be used to make a fun BBQ from, it is a KKK K14 from a Peugeot diesel car. I already have an oil pump and tank from the jetcart so apart from the combustor it is only the BBQ section that has to be built. The oil has to be changed from Mobil 1 to something more eatable since some leakage around the shaft seals is unavoidable, frying oil perhaps?

Does anyone know how high the temperature has to be in order to get a crispy surface to sausages and beefs? Without pushing the limits I can perhaps get an air temperature of 5-600C in the "stove", will that be enough or do I have to add afterburning to get even higher temps?

If you use peanut oil you may kill off half of the kids with peanut allergies! :roll:

ROFL!

JERKYJET : "Flash your steak into beef jerky in 30 seconds..."

"Also functions as a mincer, meat in the intake, cooked mince half a second later!... JERKYJET"

You love jerky, you'll love jerkyjet!
ROFL ROFL
At 600C i'd say really, really fast!
Afterburn mode would be even faster.

Ha ha, nice pic Jim!

I had some thoughts of usíng the jetcart engine for this but that much mass flow would leave all the sausages piled up to the opposite side of the grill...

The next time I am visiting my parents I will gather some material for the engine and take the carts oil system with me, this is going to be fun! =)

Thats cool! Just put another grill on the vertical plane to catch them. :twisted:

You could use like fryer baskets! Catch them cooked as they come in! 8)



Are you really going to do it! My maker , I can't wait to see one! :o

Anders -

Remember that most vegetable oils are "drying" oils. They will tend to gum up pretty badly in bearings and other "narrow spots" between runs, especially if the rig sits idle for a long time. I don't know if this is true of all vegetable oils, but it's certainly the case with most or many of them.

Years ago, I used to spend several idle hours every spring getting model airplane engines "freed up" from the congealed castor oil left in them from the prior flying season.

I asked around at work today and was told that there is a vegetable engine oil sold by Shell, and if it is classified for engine use it cannot be that bad. Using olive oil or anything else from the food store will, as you´ve pointed out Larry, ruin the bearings after a while.

What is the best approach for cooking meat on a jet stream? Simply funneling the exhaust gasses into a BBQ grill with a chimney on top or have a large frying pan with channels under it so it will be heated by the exhaust?

If the first example works it would be the best, but I am not sure if I will get a crispy surface on the food simply by blowing really hot air on it. Anyone with a hot-air oven at home that knows how it works?

Castro makes oil for 2 strokes! Castor bean oil. Smells good but I don't thnk I would eat it.

castor oil

Post by Al Belli » Thu Apr 10, 2008 7:19 pm

Hi Jim,

I don't think that the ex-Cuban dictator makes castor oil, but Castrol does.

Sorry, sometime I can't restrain My warped sense of humor.

I am beginning to think that a jet wok is the best way to go, I won´t have to use eatable oil and can cook any kind of food in it. If I get a large bucket of water to fit the propane tank in I have a beer cooler as well! 8)
