Streamliners, lakesters and fast door slammers, no radiator?

Try that on gasoline. Fuel cooled engines are gaining popularity and work because of the huge amount of fuel that is driven through them. Danny Thompson, the Nishs, the 911 roadster, and many more run this combination. When you run 30-60 gallons of fuel through the engine per run a pretty large amount is just for cooling especially alcohol.

... Any engine shot pictures? Just trying to wrap my head around what some folks are doing and what is successful for them. Thanks.

The radiator in a box...



... that we are using....




No real results as only license runs with one to 218 at 45% throttle. So no heavy loads yet but I feel it is going to be just fine.  

We have a 30 gallon main tank that pumps through the rad-in-a-box with a Mezier pump.  More on the build here with a lot of pictures ...

We agree Rex, No turbo's, No parts washing fluid, No water required.

I saw that studebaker in 2012 at the Ohio mile and it went 225mph right in front of us. We were one or two cars back from you guys. We had a lot going on and I was not able to ever see if you had any of the body panels off. So I have seen that car twice now and know it makes big boy power. Thank you for the pictures.

We do it a little different than Sparky. We have our "radiator in a box" and use a small electric pump to spray water over the radiator. We use about 1-2 gallons of water in the box at El Mirage & about 5 gallons or so at Bonneville.

When we were normally aspirated we didn't need to spray water at El Mirage and just added water to the box accordingly. Now that we are turbocharged we spray at both places.

Works for us.

Here is where the radiator in a box sits on the right side in the chassis. The box is vented outside the car. The blue cap is where we add water to the box. On the side we can remove the line that sprays water on the radiator and pump the hot water out after a pass if we need to and refill it with cool water for another run.

Mike, What is the temp that you run your engine at? My guess is some where close to what ever the boiling point of water is at the altitude you are running at.
Using the "latent heat of evaporization" means that what is cooling Mike's engine is the energy required to change the water that he sprays on his radiator into steam, which in the case of water is about 970 btu/lb. So if he is spraying two gallons of water, weights about 6.7 lb/ gallon then he is dissipating about 13,000 btus on his El Mo runs and 33,000 btu(s) at Bonneville, this combined with the the thermal inertia of the engine water and the radiator provides more than sufficient heat rejection.  I think that IO (Interested Observer) at one time suggested this method. Obviously it works. This also works for the alcohol fueled engine as the latent heat of evaporization for methanol is 470 btu/lb and if you look at spraying 30 gallons through the engine then the reason that they can live with out water jackets begins to become obvious.

On our roadster we run a belt driven meizere water pump, 110 gpm at 50-55psi in the block and heads.
We did extensive static flow testing with the block, head gaskets, heads, and valley cover return system to balance
the water flow.
This is all fed with an 18 gallon water tank, and a small aluminum radiator on the return side.
Works great at Bonneville, at El Mirage water temps are to low and only go up a couple of degrees in a 1 1/3 dirt pass.
We have about the same HP but twice as many pistons.

Mike, do you use the hot water to clean your chute like we did?

Any pictures spdracr?  The high pressure has me intrigued.
