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

Atomic Performance Products - Cosworth F1 Series Dish Top pistons suit Ford DOHC 6 cyl
Forged Pistons Ford 6 Cylinder 4.0L DOHC Engine Atomic have tried and tested to destruction virtually every piston on the market for the DOHC Ford 6 cylinder and now have available what we consider to be the pinnacle of engineering excellence in turbo piston design and manufacture. Following almost a year of development and design, Cosworth Engineering of Northampton UK have produced the most technically advanced piston ever made for the venerable Ford DOHC 6 cyl. They have produced for us a completely new forged piston which has some very unique features derived from the current Cosworth Formula One™ engine - the CA2010. Featuring a fully strutted "box skirt" design with crown support to withstand high Boost levels, Cosworth Engineers also focussed on the thermal characteristics of the forging design so as to maximise the heat transfer path from the piston crown. through the rings and into the cylinder walls, a major factor in the reliability of turbocharged engines. Produced in the UK with a bespoke forging die made specifically for our requirements, Cosworth F1 Series pistons are manufactured from the same proprietary aluminium alloy as used in the CA2010. And they come with lots of other Formula One™ bells and whistles too, such as heavy duty gudgeon pins, anti detonation bands, pressurised pin boss oil feeds, high leverage skirts complete with Xylan coating and fully polished crowns. Cosworth's legendary reputation for high performance components is second to none and will be the sole piston supplier to Atomic from 2010. Supplied in sets of 6 complete with nitro-carburised turbo rings, heavy duty gudgeon pins and locks, Cosworth F1 pistons will be available in both flat top and dish top (15cc). Our first shipment arrives in May 2010 in the following sizes: 92.6mm, 92.75mm and 93.25mm. #306305 - Cosworth F1 Series Dish Top pistons suit DOHC Ford 6 cyl Includes rings, H/D pins and locks. Suit 92.60mm finished bore size. #306306 - Cosworth F1 Series Dish Top pistons suit Ford DOHC 6 cyl Includes rings, H/D pins and locks. Suit 92.75mm finished bore size. #306307 - Cosworth F1 Series Dish Top pistons suit Ford DOHC 6 cyl Includes rings, H/D pins and locks. Suit 92.75mm finished bore size. #306308 - Cosworth F1 Series Flat Top pistons suit Ford DOHC 6 cyl Includes rings, H/D pins and locks. Suit 92.75mm finished bore size.

Connecting Rods Machine Shop Video-Engine Building DVD
Buy the "Basic Engine Building" DVD http://store.boxwrench.net/Basic-Engine-Building-DVD_p_8.html Basic Engine Building DVD - Chapter 27: Connecting Rods By now the connecting rods are ready for pistons. We recommend having the machine shop clean your old pistons for you, if you plan to reuse them. It's not fun at all by hand. Here we show you how they install the rod pins into the connecting rods to connect with the pistons. Then they will measure the pistons to determine the final bore size of the cylinder walls before they are honed. BoxWrench.net is a community and resource designed for automotive enthusiasts. The Basic Engine Building DVD is over three hours of engine building that covers everything from removal and disassembly to final assembly and engine start-up. This is the ultimate DVD for any home mechanic or engine enthusiast that wants to see a complete rebuild from Teardown to Start-Up. This video can be used to learn how to work on almost any type of internal combustion engine including V8, V6, Straight 8, in-line 6 and even 4 cylinder engines. All of the interactive features and menus will not work over YouTube. This video is great for people interested in car repair, car care, and restoration. As well as hot rods, muscle cars, performance parts, and Boosting horsepower. It can also help you to gain knowledge for increasing fuel economy, how to lower your emissions, and covers preventative maintenance to avoid little things like overheating.
