It seems like in the present high performance market power adders are the easiest way to produce a lot of horsepower without having completely rebuilding the engine. But extra horsepower puts a lot more stress on the products that hold the visit the block. Studs can solve this problem.
Several manufacturers are now offering secure on added horsepower of anywhere from Fifty to 300 additional horsepower for the extremely popular Ford Mustang Four.6 Modular Motors by bolting on a supercharger, turbocharger, or nitrous oxide. The consumer is of the opinion that it really is only a bolt on and go kit. Plus a lot of cases it could be. Especially with the less severe horsepower upgrades, driven conservatively, a package might be well suited for absolutely no additional add ons apart from a tuning upgrade.
Whenever I give a quote for a Several.6 Ford Flip-up Engine being built for use with a strength adder I always recommend that the engine is enhanced to include aftermarket head bolt studs. The actual factory head fasteners are not capable of enough clamping force to hold the head securely the obstruct for the increased cylinder head pressures due to the power adder. When the engine is producing much more horsepower and has a lot more cylinder pressure, the pinnacle is trying to "lift" from the block with each explosion in the brain chamber.
Remember within high school when they mentioned about Newton's Third Law of Motion? The third legislation states that for each action (force) naturally there is an equal and opposite reaction. In cases like this the "reaction" is the force trying to "lift" the head from the block. As the pressure to push the actual piston down increases does the force to "lift" the head increase. Sound right?
It becomes the "vicious cycle" regarding engine building. The actual stock fasteners can't hold the head effectively so you blow a head gasket. The head provides some damage plus you've got it machined several thousandths. Now the head is more susceptible to blow an additional head gasket because the compression setting has increased a bit from your machining. Again you cut the head and the method repeats itself till one day someone points too you use an upgraded set of head studs that can provide sufficient clamping force preventing the top from lifting off of the block.
