When is it time for a 2,000HP billet block? | Mazworx

In this interview we talk to Mark Mazurowski of @mazworxracingengines who is behind the SR20 billet block technology powering the current 2nd fastest 4 cylinder car in the world (6:50 @221mph) about some of the common failure points on both cast aluminium and iron blocks in high horsepower applications and some of the considerations that go into designing a billet block that avoids these issues. Also discussed are some of the advantages of products like Darton sleeves, the effectiveness of squish pads in high output engine builds and why you should always fit the receiver in the block rather than the head when using o-ring head gaskets. -------------------------------------------------- TIME STAMPS: 0:00 - Mark Mazuroski 0:33 - Factory Block Limitations 1:16 - Cast Aluminum Failure 1:41 - Cast Iron Failure 1:49 - Ovalling Bores 2:45 - Billet Block Design 3:45 - Darton Sleeves: Wet Vs Dry 4:58 - Why Use Sleeves? 5:24 - Cylinder Head Sealing Options 7:26 - Head Stud Sizing 8:15 - Head Stud Torque 9:01 - Squish Pads/Squish Area Theory 10:30 -Head Gasket Thickness 11:00 - Bore Diameter & Flow 11:55 - Squish Removal Vs Compression 12:30 - Thanks Mark! 12:50 - BUILD | TUNE | DRIVE -------------------------------------------------- Want to learn more about performance engine building?
