Another day in the office! Showing you guys how we blueprint and assemble a 4B11 Engine.
In this video we talk about using precision measuring equipment to check and adjust desired clearances, such as Piston to wall, bearing oil clearances, piston ring end gaps, etc.
We also talk about proper assembly techniques and how to ensure cleanliness when assembling the rotating assembly as this is a key factor in the engines performance.
Another topic we cover in this video is the use of ATF (Automatic Transmission Fluid) In order to clean the cylinder walls and the piston ring packs as they usually have foreign material on them that is very hard to remove without detergents. The AFT is exactly that, a Detergent that strips down the unwanted residue that was left on the ring packs from the manufacturer to prevent rust, and it also allows us to remove the rest of the contaminants from the cylinder walls before assembly, so the pistons rings get a chance to seat and create a perfect seal as soon as the engine is in operation.
Remember that the pistons rings and the cylinder wall finish directly correlate how well the compression is held in the cylinder, so we need to do everything we can to make sure that the piston rings are clean, free of ATF (Post cleaning) and the cylinder walls are lightly coated with some none synthetic (detergent free) oil, and ready to accept the piston rings so the seating process does not get interrupted.
We rate our standard "Savage Package" good for about 850 whp. We can easily increase the engines power handling capabilities with a few upgrades and tricks so it can handle 250 + horsepower per cylinder.
