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

Cylinder Head 201 - Radius Cut Valve Job
This video covers the complete valve job process that your machinist might perform. If the 100 series videos didn't help you identify and correct a problem with your cylinder head, then this is the next step. This video is brought to you with permission from my machinist in full 1080HD, and covers cleaning up the head inside and out, preparation and setting up a radius cutter, cutting all 16 valve seats, valve grinding, and spans 3.5 hours of actual work in under 30 minutes. There's nothing like this anywhere else on YouTube. THANK YOU BALLOS PRECISION MACHINE. Thank you for the professional explanation and execution of a job excellently-done, and un-precedented access to your facilities. A valve job is done by re-grinding or replacing valves, and then having new seats cut to match the faces of the valves you're using. There are several different machines that might be utilized to achieve this result, but the process is the same no matter how it's done. There are seat cutters that utilize cutting stones. There are valve seat cutters with 3 separate angles installed 120° out-of-phase, and there are single cutters with all 3 angles (radius cutter) that cut with one blade in one pass. The machine demonstrated here is a Sunnen VGS-20 Radius Cutter. This machine (now out of production) produces a gradual curved seat that's superior to the shape of a traditional 3-angle seat. While a radius cutter does contain the 30, 45 and 60 degree angles, it does so without leaving any sharp edges between their faces. My valve selection includes Supertech 1mm oversized nitride-coated stainless steel undercut and back-cut intake valves, and 1mm oversized Inconel back-cut Exhaust valves. Inconel is a high-temperature alloy utilized in marine and forced-induction performance engines that can handle more abuse than steel can without melting. The other characteristics of the valves which are discussed typically yield bigger gains in airflow than simply using a bigger hole and a bigger valve. Why I did this to a perfectly-good cylinder head: I changed cams. Because the valves were previously recessed during another valve job 9 years ago, my valve installed height was increased and this raised the operating positions of my rocker arms. My new camshaft selection dictates using the stock valve install height. The only solutions to this valve install height problem are to either replace the valve seats, or install oversized valves. I opted for the latter.

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.

Atomic Performance Products - XR6T on-car Valve Spring Tool
On-car Valve Spring Removal Tool to suit Ford 6 Cylinder DOHC Our Patented (Patent # 2006100221) tool is a simple device to facilitate quick and easy removal of valvetrain components in Ford 4.0L VCT twin cam Barra engines. The unique features of the tool are as follows: • The cylinder head does not need to be removed to gain access to the valve springs • Once the tool is fitted, all 4 valve springs per cylinder can be changed concurrently • No special skills are required to use the tool • The possibility of collets falling into the engine is greatly reduced The tool saves many hours of labour when changing one or many valve springs, valve stem seals or retainers - a mechanic can change all 24 springs in about 3 hours. Changing valve springs is very common due to the varying tensions of standard springs and their rapid deterioration in service, which in turn caused erratic idling and drivability issues. They are also regularly changed in Ford turbo vehicles as higher Boost can bring about premature valve float. To use the tool, simply remove the camshafts, fit the tool to number #1 cylinder and the 4 springs can be changed in about 10 minutes. Refit the tool to the next cylinder in sequence and continue until all are changed, refit the cams and the job is done!
