World renowned for their work building race winning pistons, Wiseco utilizes experience from a di verse back ground of the most so phis ti cated engines in such venues as For mu la 1, Indy Rac ing League (IRL), NHRA Pro Stock, Moto GP, AMA Superbike, AMA Motocross and Supercross to de sign and manufacture the highest technology pistons available.

1 Valve Pocket designs that allow maximum fl ow around valve, also allowing oversized valves and high lift cams to be utilized.

2 Piston Crown shapes designed to promote maximum In take Charge ef fi cien cy through scavenging mixture “Cross Flow” during intake and ex haust valve overlap. More fuel and air equals more horsepower!

3 Piston Domes designed for optimal quench during the compression/combustion cycle, resulting in re sis tance to det o na tion and pre-ignition. The end result is longer en gine life and increased horsepower potential.

4 Precision machined ring grooves with proper orifi ce/ac cu mu la tor volume feature calculated groove root diameters and axial widths, providing ex cel lent surface fi nish and fl at ness, maximum ring seal and min i miz ed blow-by and oil consumption.

5 World class, ISO Certified, forging facility that utilizes the latest technol ogies - Featuring complex forged shapes, advanced ma te ri als, and fea ture-aligned grain fl ow technology.

6 Complex Piston skirt profi les that reduce power rob bing fric tion, yet promote stability in the bore for optimum ring seal.

Skirt Coating





Wiseco’s new ArmorGlide skirt coating is the result of testing, development, and bench-marking through our in-house dyno program. The outcome - minimized friction, maximum horsepower, and improved wear resistance.

Not only is ArmorGlide a high-tech lubricant that reduces friction, but it also allows the piston to be fi tted tighter within the bore than a non-coated piston. Better ring seal reduces noise from piston rock. ArmorGlide is being applied to selected pistons.

As the leader in LS-1 forged pistons, Wiseco pulled out all the stops when designing the LS Series. These pistons are designed to accommodate the reluctor ring on stroker cranks without having to notch the pin bosses.

Offset pins like O.E. and skirt shapes specifi cally designed for street applications make these the best available. They have been tested successfully in the highest horsepower applications.

Wiseco Quick 16 pistons are designed to fi t conventional heads from today's leading manufacturers.

Wiseco Quick 8 pistons are designed to allow for additional fl ycutting as necessary. Domes that can be cut to a lower rise to tune volume for different combustion chamber volumes. Every 2.76 grams off dome/valve pockets = 1cc volume.

• New skirt coatings use Wiseco’s proprietary ArmorGlide™ material (Superior to graphite or Tefl on based formulas). Benefi ts include - longer engine life, increased horsepower, noise reduction, and much tighter dimensional tolerances than typical spray-on coatings. Controlled curing processes guarantee the best possible results.

• Designed with input from today's leading edge engine builders and Pro Stock technology to fi ll the demands of today's big valve, big cubic inch Sportsman Series engines.

• Confi gured to maintain proper fl ame travel and desired compression ratios needed for today's extreme horsepower engines and exotic fuels. Generous valve pockets for all popular heads and high lift cams

• With the ability to produce dedicated forgings in house, Wiseco is able to design pistons with the lightweight extreme durability that is expected in a modern day race engine. Fortifi ed pin bosses, maximized ring lands, dedicated skirt shape designs to minimize piston rock, and reinforced deck and pockets, all add up to handle the shock loads of modern day power adders

• Vertical Gas Ports located away from valve pockets.

• Oil reservoir below oil drainbacks allow the lower rail to act more effi ciently for optimal oil control.

• Ring packages incorporated to handle the highest cylinder pressures and temperatures.

• In stock availability of kits and singles keeps you racing all season.

Compression Ratio Calculation

Formula to determine Compression Ratio .7854 x the number of cylinders x stroke x bore x bore = Total Cubic Inches(Total Cu. In.) _________________________ ÷ # cyl. = _________________________________ (Cu. In. per cyl.)(Cu. In. per cyl.) _______________________ x 16.387 = ___________________________________(cc per cyl.)

____________________________________ Gasket thickness+ ___________________________________ Deck thickness= ___________________________________ Total

.7854 x the number of cylinders x stroke (gasket + deck total) x bore x bore = Total Cubic Inches(Total Cu. In.) _________________________ ÷ the number of cylinders = (Cu. In. per cyl.)(Cu. In. per cyl.) _______________________ x 16.387 = (cc per cyl.)

____________________________________ cc of gasket + deck ____________________________________ cc of combustion chamber- ___________________________________ cc of dome+ ___________________________________ cc of valve reliefs or reverse dome ____________________________________ Total assembly volume ____________________________________ Assembly volume ____________________________________ Cyl. volume ____________________________________ Total

Assembly volume, plus cylinder volume, divided by assembly volume = Compression ratio

Replacement pistons for 8-cylinder Chevy & Chrysler motors

• Cylinders 1, 4, 5 & 8 are left pistons and have exhaust Valve Pockets on left side.

• Cylinders 2, 3, 6 & 7 are right pistons and have exhaust Valve Pockets on right side.

• 900 V-6 Chevy motors require 4 left and 2 right pistons.

1 Dome and reverse dome shapes have smooth contoured surfaces for better combustion and optimal quench for detonation reduction!

2 Symmetrical valve pocket designs allow maximum fl ow around the valves during overlap and accommodate oversize valves and high lift cams.

3 New screen printed skirt coatings for 2010 use Wiseco’s proprietary Armor Glide™ material. Superior to graphite or Tefl on based formulas, benefi ts include longer piston life, increased horsepower, noise reduction, and much tighter dimensional tolerances than typical spray-on coatings. Controlled curing processes guarantee the best possible results.

4 Complex Piston skirt profi les reduce power robbing friction and rock, which promotes stability in bore for optimum ring seal.

5 Precision machined ring grooves provide excellent surface fi nish and fl at-ness for maximum ring seal and minimized blow-by and oil consumption.

6 World class, ISO Certifi ed, forging facility that utilizes the latest technolo-gies, featuring complex forged shapes, advanced materials, and feature- aligned grain fl ow technology.

With the leading tip of the lock in the 12 o'clock position, insert your thumb thru the center of the lock and hook it under your thumbnail at the 10 o'clock position (roughly 1/2" to the left of the leading tip). Install the leading tip into the 11 o'clock position of the groove. (If the wrist pin hole intersects the oil ring groove, lock installation is slightly more diffi cult as the lock will catch on the bottom ring land). The leading edge of the lock should catch in the groove, allowing it to stay on its own. Continue by applying pressure with a counter-clockwise motion until it fully snaps into place. The correct number of Spiro Locks MUST be installed in each piston or severe engine damage may occur. Do not over-stretch or re-use Spiro Locks. Do not install Spiro Locks in press-fi t pin applications.

• Pistons listed with a compression ratio range: low number is with un-cut deck, high number is block decked to .030 piston to cylinder head clearance. • Always check piston to valve clearance - If using VTEC or like mechanisms-check w/ longer duration higher lift lobe. • Always run at least .030 piston to head clearance including gasket thickness. • If piston appears to be different than expected, please do not hesitate to call Wiseco at 800-321-1364 to verify compatibility.

1. Most Wiseco pistons have offset pins. Offset same as o.e. for quietest operation (pin offset will be opposite of direction of engine rotation).2. Due to a compression height that may protrude above the deck, it is recommended that a .040" thick head gasket is used.3. Uses an extra thick (.200") wall piston pin. Optional .225" wall, tool steel pins also available.

1. Most Wiseco pistons have offset pins. Offset same as o.e. for quietest operation (pin offset will be opposite of direction of engine rotation).2. This piston is a fl at top w/out valve pockets, to be used if verifying piston to valve and piston to head clearance.6. These pistons have an oil ring groove that is lower than OE. Will not work with sleeves with access hole if the oil ring is not pinned in place.

1. Most Wiseco pistons have offset pins. Offset same as o.e. for quietest operation (pin offset will be opposite of direction of engine rotation).2. Due to a compression height that may protrude above the deck, it is recommended that a .040" thick head gasket is used.

These gaskets use a high pressure steel laminate design. They will withstand extremely high shear forces that occur between an aluminum head and iron block.

It's internal embossments expand with heat to create a better seal when under extremely high combustion pressures and temperatures - as is the case with heavy ni-trous and turbo-charged applications.

Racing Pistons

These Brush hones have been specifi cally designed to clean the surface of the cylinder bore and provide a fresh cross-hatched surface without removing material (which can increase piston to wall clearance and ring end gap).

Always use an ample amount of honing oil to carry away debris. Wash cylinders thoroughly, with hot soapy water, until paper towels remain clean with no signs of discolor-ation. Then prep cylinders with any anti-rust agent.

• True 4340 forging.

• Core hardened, tempered to reduce stress and optimize tensile strength. Nitriding process for hardening rather than induction heat treated (which leaves the area between the journals soft and subject to post-running deformation from internal stresses being relieved).

• Magnetic particle inspection.

• Straight oiling to journals insures constant fl ow rather than stalling at intersection as seen with cross drilled cranks.

• Wide pin-end widths designed to support the wrist pin (which reduces pin fl ex and associated problems).

• Exception Journal fi nish.

• Excellent Journal dimensional tolerance (roundness, taper, bell mouth & barrel) .0002 maximum.

• Counterweights placed for optimal load reduction and ease of balancing.

• Stress relieved.

• Internally balanced.

• 4340 steel forgings.

• Special bushing material for optimum friction reduction.

• Proprietary bolts produced by ARP to K1 speci-fi cation with asymmetrical threads to equally load each thread when under tension.

• Pin oiling.

• Heavy radii.

• Thicker blades.

• Double bridged caps reduce housing bore distortion.

• No ridge between the blades to act as a stress riser.

• Rod offset is designed to center small end to bore center.

• Big end housing bore is held to +/ .000050” (50 millionths).

• Center to center less than .001”.

• True 4340 forging. K1 Crankshafts

• 4340 steel forgings. K1 Connecting Rods

The relationship between K1 and Wiseco is an industry fi rst. For the fi rst time, rotating assembly components are being designed around each other from their inception. This enhances strength and eliminates mass.

The professional engine builder will note that the assembly balances well and fi tment is exceptional. Power and longevity are increased through a reduc-tion in mass, friction, and windage.

Connecting Rods






Not only do connecting rod bolts see the same tension loads that try to pull a connecting rod apart, the total weight of the tower portion of the rod is trying to follow the piston up through the cylinder head. Connecting rod bolts are the most highly stressed fastener in the engine! They need to be properly tightened.

Setting a torque wrench at a given number and tightening until this set amount of torque is reached is easy, but it can be highly inaccurate. A torque wrench only measures the amount of resistance it takes to turn the bolts. The amount and type of lube that is used will affect the actual clamp load provided by the bolts. Also, each time a bolt is tightened, the mating surfaces of the threads, the spotface on the rod and fl ange of the bolt get smoother, which changes the amount of torque that is required to properly tighten the fastener.

A bolt is simply a very stiff spring and it must be stretched a predetermined amount to keep the rod cap on and the bearing from spinning.

You've spent a lot of time and money building an engine...

don't risk damage by failing to take a few minutes to put it together correctly.

It's important to note that a fastener is like a very stiff spring and it must be stretched a specifi c amount. The material’s ability to “rebound” like a spring is what provides the

clamping force to keep the rod bolted together. If you do not stretch the bolt enough there may not be enough clamp load to keep the rod cap in place, which could result in broken bolts or spun bearings. If you stretch the bolt too much, you can exceed the yield strength of the fastener which will weaken it and cause it to fail. Either of these two conditions can result in catastrophic damage to your engine. Always follow the manufacturer’s instructions to prevent damage to your engine.

Methods used for tightening Rod Bolts

Stretch Method: Measuring bolt stretch is the most accurate method for tightening rod bolts and insures the correct pre-load. Simply measure the free length of the

bolt before tightening, lube the bolt threads and rod spotface. Install the bolt into the rod and tighten until the bolt is stretched the proper amount. K1 Technologies offers

an economical bolt stretch gauge for this purpose.

Torque & Angle Method: Do not confuse this with the “Torque to Yield” method. Torque to Yield stretches the bolt to a point where it will no longer return to the original length when

loosened and requires the bolt to be replaced after each use. When using the Torque & Angle method, you lube the bolt threads and rod spotface, tighten the bolt to a low torque value (as prescribed on the instruc-tion sheet) then, using an angle gauge, turn the bolt a prescribed number of degrees to properly stretch the bolt. This method uses the highly accurate pitch of the bolt thread to control the amount of stretch.

Torque Method: Torque does not measure clamp load and only measures the amount of friction that must be overcome to turn the bolt. The friction of the mating surfaces of the threads, rod spotface and bolt fl ange change with each tightening. When you consider the fact that different amounts and types of lubes also change the friction, using the torque method is like trying to hit a moving target that you cannot see. K1 Technologies does not recommend the use of or provide torque values for tightening bolts.

Adherence to proper boring and honing procedure is essential to overall ring performance. To ensure that the bore finish will retain an oil film, it is vital that the guidelines listed below are followed for cast iron bores.

• Install and torque main bearing caps

• Use torque plates. This simulates the distortion that occurs when the cylinder head is mounted to the block. (hint: After boring and honing, leave the torque plates in place and fit/gap the piston rings to their respective cylinders.)

• Allow for a minimum of .003" excess material for use as honing stock.

• Intermediate hone to within .0005" of finished size with #220-#280 grit stones. (With diamond stones use #280-#400 grit.)

• Finish hone with #400 grit stone or higher. (Use #600 grit diamond stone. If using hand operated equipment, set drill speed between 200-450 rpm.)

• Finish with an appropriate stone or tool to achieve desired plateau finish (see below).

Plateau honing is the popular name for the process that replicates the

cylinder bore surface finish normally produced by the rings after they have worn down the surface peaks during "break in". This technique produces flat areas or plateaus (Rk) on the cylinder wall after finish honing by using a very fine grit stone or a PHT type brush tool to remove the peaks (Rpk) from the surface. This lowers the overall roughness average (Ra) while maintaining valley depth (Rvk) in the cross-hatch pattern of the cylinder wall. A high Rvk value is very desirable for oil retention qualities and will substantially reduce "break in" time and increase ring life.

Ra (Roughness Average) = Used to describe surface roughness as an average between the peaks and valleys that exist in a finish over a specified area, usually micro inches.

Rpk (Peaks) = Average peak height.

Rvk (Valleys) = Average valley depth.

Cross Hatch = The pattern of intersecting parallel lines left after finish honing operations are completed. The smaller the intersecting angle, the larger the area (Rk) between the hone marks.

Maintaining the proper cross hatch angle is important for two reasons; 1. Oil retention on the cylinder wall and 2. The rate of ring rotation. Excessively shallow cross hatch angles can hinder or slow down the necessary ring rotation that allows dissipation of heat. It can also leave too much oil on the cylinder wall allowing the rings to skate over the surface leading to excess oil consumption. Too steep of a cross hatch angle may not provide adequate oil retention and can result in dry starts and premature ring wear. A steep pattern angle can also create excessive ring rotation that will accelerate ring and piston ring groove wear.

Axial Clearance: The distance between the ring axial height and the piston ring groove width.

Axial Height: The width (thickness) of the ring in the axial direction.

Back Clearance: Distance between the inside diameter of the ring and the back of the ring groove when the ring is fl ush with the ring land. D-wall: A specifi cation established by the Society of Automotive Engineers (S.A.E.) that dictates the radial width of a standard automotive piston ring by the use of the following formula: Bore diameter divided by 22 = radial thickness (3.386” divided by 22 = .154”)

End Gap: The end gap clearance when the ring is compressed to the bore diameter.

Gas Nitrided: A process used to harden the perimeter of a ring where nitrogen atoms penetrate the base material and form an extremely hard outer layer that provides excellent wear and scuff resistance.

A. Neutral Barrel: A term used to describe a piston ring that has no torsional bias or twist.

B. Positive Twist: An asymmetric change in the ring cross section that causes it to twist in an upward direction (toward the piston crown) aiding ring sealing of the top and bottom of the ring groove. Positive twist is used only on top compression rings.

C. Reverse Twist: An asymmetric change in the ring cross section causing the ring to twist downward (toward the piston skirt) that enhances the second compression ring’s oil scrapping properties.

Radial Width: The width of the ring in the radial direction.

Ring Axial Sides: The top and bottom surfaces of the ring.

Ring Face: The section that contacts the cylinder wall.

Torsional Twist: The installed position of the ring due to a chamfered area on either ring side that helps the ring cross-seal.

Ring Terminology

Ring Gaps

Ring Gap Table Instructions1) Cylinder bore size must be in inches. If measuring millimeters, divide

bore by 25.4.2) Multiply your bore size by the “x Bore” column for your application.

Proper Ring Gap Measuring Procedure1) Torque Plate should be attached to engine block or cylinder and torqued to specifi cations. 2) Cylinder bore should be free of taper. 3) Piston ring should be square in the bore 1” down from the deck.

Proper Ring Gap Filing 1) Ring gap should be fi led using proper ring gap fi ling tool. 2) Ring gap should only be fi led in an inward direction and square to the sides.

Wiseco oil rail supports feature a special dimple to prevent rotation of the oil rail. This dimple should be positioned directly in line with the piston pin. Keep the rail support gap 90 degrees from the pin bore opening.

Use caution when grinding ring end gaps - A stone or cutter which is too coarse can remove material too quickly.

Oil Rails & Rail Supports

When installed in a horizontally opposed engine, rail gaps should be installed as shown to the right. The rail tab must be installed below the oil ring expander with the tab facing toward the bottom of the ring groove extending into the split oil drain back hole. Use caution to not install the rail tab into the piston pin oil hole. The gap should be situated to the top of the engine to block oil migration at the bottom of the cylinders.

As a piston moves down on the power stroke, combustion pressure accumulates in the land area of the piston (between the top ring and the 2nd ring.) This accumulation of pressure can cause the top ring to unseat from its sealing area at the bottom of the ring groove. This is addressed by increasing the gap area of the 2nd ring. This affords a controlled release of the inter-land pressure, and keeps the top ring seated on its lower sealing surface for improved performance.
