The 2618 piston is more subject to wear in the ring lands and skirts. In the case of pistons that have a graphitized skirt, another 0.015-0.020 mm should be deducted from the measured piston diameter to allow for the thickness of the layer; this gives the nominal diameter for the piston which is stamped on it. by Mike Rogers » Thu Aug 23, 2012 10:05 am, Powered by phpBB® Forum Software © phpBB Limited, General engine tech -- Drag Racing to Circle Track, Has any one used the icon pistons that speedway sells. by Bernard Mondello » Wed Aug 22, 2012 12:14 am, Post There's only one reason to race; that's to win.

Built from 11% silicon 4032 aluminum, FHR pistons can be installed with tighter piston to wall clearance for quiet operation and increased piston stability. They are made in Mexico. Due to their high strength and lower wear values, these pistons make it possible to comply with low exhaust and emission standards, especially for diesel engines under heavy loads. The Elite series also comes standard with an Anodized top ring groove and piston crown.

ICON Premium pistons are designed to be application specific and are made from either 4032 or 2618 aluminum. Your best bet is to call Marko Glush at ICON and ask him questions instead. A forum community dedicated to Chevrolet Chevelle owners and enthusiasts. It does not say how much they weigh or if they are maybe in the USA or not. The PowerPak pistons are made from either 4032 aluminum alloy to allow for tighter cylinder to wall clearances and improved temperature stability, or 2618 alloy to allow for increased detonation resistance. LCAT pistons are made from high strength 2618 aluminum, and feature not One, not Two, but Three protective barriers as standard features! Valve recess depth. 2618 aluminum has a lower silicon content than 4032 and is better suited for engine combinations with high compression or a power adder. Ring carrier pistons with cooling channel and crown reinforcement These pistons are used in diesel engines under heavy load conditions. Icon Pistons IC945-030 Fits Jeep 4.6L Dish -10.8cc 3.905 Bore $427.95 Fits AMC/Jeep 4.6L Inline 6 Cylinder, Bore 3.905, Stroke 3.895, Rod Length 6.123, 439 grams, Dish -10.8cc, Set of 6 Pistons Forged pistons The state of the art in motorsport is now used in highly loaded series production engines as well: the forged piston. Pistons made from this alloy can be installed with tighter piston to bore clearance, resulting in a tighter seal with less noise. However, some of the pistons and pins are color coded.

In addition, the use of 4032 aluminum decreases the friction created during engine operation, this results in extended piston life and reduced wear. ECOFORM® pistons with pivoting side cores Weight optimized pistons for passenger car gasoline engines. In addition, we apply our UltraTherm CM heat reflective thermal barrier to the piston crown. On assembly it must be ensured that the components are lubricated sufficiently. Can't seem to quit. Additionally, shock load and degradation to engine bearings is reduced. what is the problem with the hypertectic?W hat applications are they made for does anyone know??

That translates into more power at the wheels. 4032 is a high-silicon, low-expansion alloy.

ICON Premium pistons are designed to be application specific and are made from either 4032 or 2618 aluminum.

Once the engine warms up the noise subsides as the piston expands to its running clearance. by F-BIRD'88 » Wed Aug 22, 2012 6:23 am, Post 1971 Chevelle: L96 6.0, 232/244 cam, t56, 411's, 460whp/430wq...still trying for 11's.. 12.3 @ 115 1.89 60'. JavaScript is disabled. With pin boss bushes made from a special material, the load-bearing capacity of the pin boss is increased. For a better experience, please enable JavaScript in your browser before proceeding. Arias has proven they have what it takes to be a top manufacturer for all time. The pins are 141 grams, all within .0001 of each other. Unless you rebuilding an engine with little to no budget you're going to upgrade to aluminum forged pistons. Are you building a street/strip machine or an all out racer? Pistons have to put up with extreme pressures, as their working conditions have become significantly tougher in recent years. This provides the pistons with significantly improved heat removal properties, especially in the first ring groove.

The Elite series features our Line2Line adaptive Skirt Technology Coating, to reduce friction between the piston and cylinder wall and provide additional protection at start-up. From the FHR series to the LCAT, ICON offers the most diverse and fully-featured “Off the Shelf” forged piston on the market today. 4032 is a more stable alloy, so it will retain characteristics such as ring groove integrity, for longer life cycle applications.

Our FHR (Formed Head Relief) line of pistons delivers professional quality on an enthusiast budget. YES, because we're winning! by monte442 » Wed Aug 22, 2012 12:11 am, Post The MAHLE® repair pistons are ready for installation with mounted piston rings. by Enigma » Wed Aug 22, 2012 4:32 pm, Post Which Mahle Piston Is Right For Your Engine.

ICON Premium pistons include all the features of an FHR piston, with the addition of precision CNC machined valve reliefs and crown features, pressure fed pin bore oiling, and skirt and pin boss struts for increased strength and durability. Consider, for example, the MAHLE design for the Chevrolet 4.3L 200 HP truck engine. The majority of Mahle forged PowerPak kits are made with 4032 alloy and require no additional piston-bore clearance. cast and hyper pistons are basically the same thing, the hyper is an added material IIRC... cast and is usually whats in most stock engines, some have hyper, slightly stronger than cast, but more brittle. 2618 aluminum has a lower silicon content than 4032 and is better suited for engine combinations with high compression or a power adder. MAHLE Aftermarket Inc.23030 MAHLE DriveFarmington Hills, MI 48335, © by MAHLE Aftermarket GmbH, Stuttgart 2001 - 2020. Are we having fun yet? The forgiving characteristics allow for the most extreme conditions, but longevity is eventually negotiated after countless heat cycles. There are also alternative ligthweight pins available, as far as I can remember (Look in the PDF cat.) Besides being stronger than cast pistons, the lighter aluminum cuts parasitic power loss. by Caprimaniac » Wed Aug 22, 2012 5:14 pm, Post Consider forged pistons as insurance. FHR pistons have valve reliefs that are formed into the piston as the forging blank is pressed into the die. They were flat tops and they had a small crown in them .003 had to take the engine back apart and mill flat. The skirts of every LCAT piston, receive our Line2Line Adaptive Skirt Technology coating. Post They have several different pistons for the same engine,some are 5/64 rings and some are 1/16 rings,best thing to do is go on their website and look at all of the specs. Because of this, pistons made from 2618 require more piston to cylinder wall clearance than their 4032 counterparts. MAHLE's eutectic (12% silicon) aluminum alloy is performance proven in literally millions of engines around the world including high output diesel engines and Formula One racing. Prior to assembly, the con rods have been checked to see that their bores are on parallel axes (to ensure that there has been no bending or twisting), and if necessary, they have been replaced. Two-stroke These pistons are mainly used in gasoline and diesel engines for passenger cars under heavy load conditions. For additional protection and to avoid cavity edge or crown fissures, these pistons have a special hard anodized layer (HA layer) on the crown. The stated piston diameter added to the corresponding clearance gives the cylinder diameter. MAHLE® pistons are OE quality and have many premium OE features. Because of the high temperatures at the piston top and the ring belt, intensive cooling is provided with oil circulating through the cooling channel. I hope this helps!

For instance. No matter what your high-performance application calls for, there is an ICON piston for you. The choice to use one over the other depends on your project.

Cast solid skirt pistons have a long service life and can be used in gasoline and diesel engines. by Keith Morganstein » Wed Aug 22, 2012 6:12 am, Post Each ICON piston is purpose built from the ground up for extreme high-performance street or racing applications. Your IP: 139.59.20.20 On the crown of every LCAT piston, you will notice the familiar top land and crown Anodizing from the Elite series of pistons.
