Stroker kits.com Announces the Industry – Exclusive BBS System

 Bessel Motorsports, Inc. the home of the exceptional Bessel splayed caps have captured the racing industry once again with its patent – pending Bessel Block Supports. Which provide significantly improved block support by adding a .003″ pre-load in the engine block.

Many diehard Ford enthusiasts knows, the 302 Ford factory blocks are notorious for splitting at 500 – 550 hp and so is the new 360 Chrysler Magnum blocks. These blocks cannot withstand the increased levels of horsepower of today’s power additives such as stroker kits, large amounts of compression, NOS, turbos, and superchargers. The consequence is always the same the block will split down the lifter valley area, which quickly destroys everything.

The solution is easy the new Bessel Block Support, but lets look at why these blocks split in the first place. The answer has always been right on top of your motor. The intake manifold is the reason for this weak design and destruction, when you bolt up a 302 Ford,  or a 360 Chrysler Magnum manifolds your Intake bolts will go straight down into the block, and this puts a wedge into your blocks. As your horsepower number go up you are causing a great amount of stress and flexing on the block. With the wedge in the block it simply cannot withstand the levels of high loads, and is unable, to live up to advances in engine power.

Now, lets look at the 350 Chevy manifold how many of those blocks have you seen split down the middle? Almost none…….. the reason being the Intake manifold does not put a wedge in the block. Your small block Chevy manifold bolts go in at angle putting a pre-load into your block.

The Bessel Block design puts a .003″ pre-load in your block (the block will pull itself together like the small block Chevy manifold does) and is held in position with six dowel pins and cap screws.

The Bessel Block support system overwhelmingly increases the blocks stability. These are precision block supports, which are designed from the centerline of the camshaft. The Bessel Block Supports must be installed with a bridge-port or CNC machine.

 

Another Example / Explanation

The 302 Ford blocks are notorious for splitting at 500 – 550 hp and so is the new 360 Chrysler Magnum blocks.

 

Do you know why?

 

 The answer is simple it is your intake manifold causing all of your problems along with cap walk. What happens is when you bolt up a 302 Ford and 360 Chrysler Magnum manifold your bolts will go straight down and what this does is puts a wedge into your blocks. When you start creating decent horsepower and your caps start moving inward they will egg-shape and cause the cap to lose its register. When this goes unattended for a period of time it will put stress on the hardware holding your cap in place. This will push the stud or main bolt over enough to crack the stud housing.

 

 

 

Once this occurs the wedge in your block that was put there by the intake manifold will automatically split the block in half because of the weak design. If you look at a small block Chevy the intake design is totally different. When they install the manifold the bolts go in at an angle putting a pre load into the block and pulling it together.

STOP “main cap chatter”

Over the last fifteen-plus years, as the street / strip hobby has grown to unpredictable dimensions, the venerable production blocks have been used and abused by countless numbers of racers. In the process, there have been more cracked blocks that would fit into a warehouse. As a result, there has been a need for a solution to the cracking problem. Some companies in the aftermarket have chosen to build a bottom-end girdle, which ties all of the main caps together in order to prevent then from moving around under the intense amounts of cylinder pressure that blowers, turbochargers, and nitrous oxide produce. As the pressure builds, the main caps tend to want to assume an oblong shape and “close up”, and Bessel’s Motorsports Splayed Main Cap system puts all of those fears to rest. The ingenious solution has proven its worth in numerous applications, and Bessel Motorsports can build a main cap system for virtually any pushrod motor including most aftermarket blocks. – RacePages April 2008

 

As any diehard racing enthusiast knows, typical racing main caps are unable to withstand the increasing specification levels of high loads, and are unable to live up to advances in engine power.  When stock main caps are used, the motor will knock the register out of the cap (“cap chatter”); this causes a great amount of bearing damage and horsepower loss.  The consequence is a flexing of the block, which quickly destroys the main bearings and eventually, the crankshaft.

 Now, let us look at the Bessel Splayed Caps (U.S. Patent # 7,322,750) in comparison. Not only an improvement by its superior cross-sectional strength, but the amazing advantage is its ability to lock into the block and eliminate the ability of the cap to move inward.  And if the cap cannot move inward, then there is no “cap chatter” – no “cap chatter” means NO horsepower loss, NO bearing damage, and NO destruction of the crankshaft!

 Simply put, the Bessel Splayed Caps overwhelmingly increases cap stability.  This breakthrough design improves reliability in High-stressed engines by locking-in with the block and reliving high stress loads in the middle of the block to the outside pan rails. This is accomplished through the precision machining process of the block. It also reduces distortion of the main-bearing bores by increasing the cap’s resistance to closing up under high loads.
