Why do people fill engine blocks with concrete?
A: The short answer to all of your questions is—yes. Block filler can improve cooling and cylinder strength, and it can be used in a street engine successfully. The type of filler you want to use is called “short fill,” which means that enough filler is used to partially fill the water jackets in the block.
What is a concrete filled block?
The concrete blocks that are used to build block foundations are hollow. After the concrete blocks are laid, the voids can be filled with a cement-based mortar or poured concrete that contains small pea gravel. If the builder does this, the filled concrete block walls become nearly identical to poured concrete walls.
What is a grout filled engine block?
It is filling the water jackets with grout making the block more solid to strengthen it. It is used mainly in drag engines that do short runs so cooling isn’t necessary. I am no longer in business but I will answer questions.
What is the purpose of block filler?
Block filler is a filler material used under epoxy, alkyd and latex top coats for interior and exterior concrete finishes. It is used in masonry preparation on concrete block and cinder block (poured and precast). It is used before top coats so that the surface assumes a flat, smooth and uniform profile.
How can I make my engine block stronger?
What if you plan on an even higher torque output from the engine? Then, you will need to consider going to a larger diameter head stud. Moving from a 10mm to 11mm head stud requires the installation of Time- Serts on every head bolt hole on the engine block.
Can you fill concrete blocks with sand?
Try to compact the sand as much as possible to ensure a sturdy ‘infrastructure’ for your cinder blocks to rely on. If done right and compacted enough (8-12 inches), you won’t really need to pour concrete. This can be done in wet areas as well.
Can you run a filled block on the street?
Just fill it to the bottom of the water pump holes and it’ll be fine on the street. It stiffens the whole main web of the block as well as absorbs harmonics. Just be sure to fill it before doing any machining.
Can block filler be sprayed?
Before applying concrete block filler, a professional will purge spray equipment before using it with a reducer. An expert can also use an airless spray to apply concrete block filler will use the recommended pressure of 2000 psi. The hose should be ¼ to 3/8 inches, with a tip of . 028 inches.
What is a filler block?
Filler Blocks – are blocks constructed of thick plywood, OSB or dimension lumber to fill the gap between double joists. They are required when the double joist member is supporting load from one side.
What is the strongest engine block material?
Cast-iron versus Aluminum In simplest terms, cast-iron is a stronger material with a harder surface that is more resistant to wear. This allows cast-iron blocks to have the cylinder walls integrated as parts of the block itself. On the downside, cast-iron blocks are heavier.
What do you fill engine blocks with before hard Blok?
Before Hard Blok, many racers and engine builders experimented filling blocks with various substances. Many had some very shocking and ill effects. Way back about 1982, I had a customer’s block someone filled with some sort of industrial equipment, concrete type grout. Like concrete, the substance had been mixed with water.
How does hard Blok water jacket filler work?
HARD BLOK WATER JACKET FILLER is a specially formulated, cement-based product with refined, size-graded iron particles combined at an optimum ratio to provide maximum strength, vibration dampening, and heat dissipation required in high performance race engines. Its coefficient of thermal expansion is identical…
What kind of block filler do drag racers use?
Many drag racers still practice that modification. Today, racers have the luxury of a low-cost block filler called Hard Blok, provided by Joel Bayless. Back in my early Pro Stock days, when I was racing Cleveland small blocks, we had to use a very expensive Devcon aluminum epoxy. It was easy to use and it poured like cake batter.
What kind of epoxy do you use for block fillers?
Back in my early Pro Stock days, when I was racing Cleveland small blocks, we had to use a very expensive Devcon aluminum epoxy. It was easy to use and it poured like cake batter. It bonded to anything, had nil shrinkage or expansion when hardened and weighed slightly less than the water it displaced.
