Engine Parts Balancing
Balancing of pistons and conrods.





Cylinder Head 106 - Casting & Porting Tech
Description. No really guys, what can I type here? I just went on for 18 minutes without shutting up. I apologize for deviating from my normal format, but we're almost there... ...when I port a head, there will be no voiceover, and it will be a 200-series video.





Blueprint 103 - Connecting Rods
Connecting rods are the crux of the engine. They're responsible for carrying the force of the explosions that occur in the combustion chamber and using it to turn the crankshaft. Oil clearance specifications of the "big end" and "small end" are crucial to maintaining consistent oil pressure. In this video we take 3 measurements: Rod Gap Rod Journal (also called Crank Pin) Diameters "Big End" Bore diameter Using the Journal diameters and the "Big End" Bores, you can calculate your oil clearances of each bearing. The process is illustrated here. Anyone rebuilding an engine who doesn't know its history should check all of these clearances whether or not they're re-using the rods. If the crank, bearings or connecting rods are going to be replaced, it's imperative that you measure the new parts as well to ensure they're in spec.

Crankshaft Refurbishing
Many of you have seen this one before. I apologize if bringing it back offends anyone. Domestickilla gave me a crankshaft, and it's a nice one that I want to clean up and use again. You'll be seeing a lot of it and because of this, this video deserves to be here. I fixed what I broke, and this was my experience. In this video Ballos Precision Machine demonstrates magnetic dye penetrant testing, crankshaft polishing and inspecting the balance of a "butchered" 4g63 6-bolt crankshaft.





Blueprint 106 - Cylinder Bore Inspection
We're close to the end of the 100-level series. In this video I show you how to measure the cylinder bores using 2 different tools. I compare the results and illustrate what to look for to determine whether or not your engine is in-spec. The block I'm using is a 6-bolt turbo 4g63 from early '92. It has 150,000 miles and this video also serves as a testimony for the durability of Mitsubishi's cast-iron solid-decked Sirius I engines. This engine will be cut for a new set of pistons, so these measurements are needed to determine what size pistons I need to get. .030" is as far overbored as you should ever take a 4g63. Boring larger than that will take too much off the side clearances between the cylinder walls and result in compromised strength from hot spots. The only time you'll ever need to cut a bigger hole is when an imperfection prevents you from using the pistons you have, or if you're changing to a larger piston. If you cut the block to its service limit, you have no room to fix an imperfection should one develop... so it's best to cut as little as you can get away with. Boring a cylinder .020" over does not significantly increase its displacement.





Atomic Performance Products - XR6T High Performance Conrods
Atomic billet steel conrods were designed from scratch with one principle in mind; use aerospace quality materials and sophisticated manufacturing processes to produce an extremely strong, light and durable connecting rod for the popular inline 6 cylinder Ford SOHC/DOHC engines, at an affordable price. The Design and Evaluation Process The Atomic engineering team set out to address these parameters by designing what many performance engine builders are now calling the finest conrod on the market for the Ford DOHC 6 cylinder engine. Extensive CAD/CAM computer modelling was employed and produced a H-Beam design, which has an extremely high stiffness-to-mass ratio. The next step was to pick the correct materials, heat treatment and surface treatment processes to ensure durability under rigorous performance applications. Next came FEA modelling (Finite element analysis) to simulate stresses on the conrods. This also entailed weighing every piston, gudgeon pin and ring set on the market and loading this information, plus stroke, rotating and reciprocating conrod values into our computer modelling software to calculate the stresses. The greatest load exerted on a conrod in an engine producing 600 comes not from the force of normal combustion but from the tensile force exerted by the piston at top dead centre (TDC). At 5250 RPM the piston exerts a tensile load on the conrod of 1908 gs (-1693 kgs) at split overlap TDC reversal. If you increase maximum engine speed by only 1000 RPM to 6250 RPM, the TDC tensile load rises by 50.4% to 2870 gs. At 7500 RPM the tensile loading increases to 4132 gs, clearly demonstrating the Atomics design strength of 8000 gs means it has plenty in reserve. Excessive loads at TDC are brought about by a high reciprocating mass and/or by increasing engine RPM, so it is essential to design reciprocating engine components with the lowest mass possible to minimize premature lower bearing shell bearing failure. This is particularly relevant to our customers who are turning their engines to 7500RPM+. For more information, visit http://www.atomicperformanceproducts.com/conrods.html
