Piston Set TwinSpark 2.0 84mm 11.5:1 Dish Dome Low Friction Asymmetrical Skirt Design
[JE84TS11.5]
$0.00

This part is discontinued and no longer available. Please DO NOT try to order.

 

NEW SQUISH/DISH DOME MAKES MORE POWER

  • Dished dome makes more power. Flame front travel distance is minimized when compressed charge concentrated directly under spark plugs combustion efficiency is improved.
  • Tall shoulders of dome "squash" the mixture at TDC creating a hurricare to distribute the flames.

CUSTOMER TESTIMONIAL

"Your new TS dished TS pistons worked an absolute treat and our customer is absolutely over the moon with the performance of the engine.  Having changed nothing other than the pistons and compression ratio, the car has jumped up two classes and is now a seriously quick Alfa.  It performed faultlessly.  We love them!  Well done guys!!!  A fantastic set of pistons."

NEW! ASYMMETRICAL DESIGN. This slipper skirt piston type design features:

  • The intake skirt is 20% narrower than a full skirt, rod angularity creates greater pressure on the intake side load before TDC.
  • The compression decay  after TDC reduces the exhaust loading allowing a 40% reduction on the exhaust skirts.

Standard Features:

  • Compression of 11.5:1 is measured with standard head of 135mm height and 1.6mm Reinze gasket. WARNING:  Milling drastically increases coompression.  Also, be aware that valve shape/size and seat height can make a difference.  For absolute accuracy, customer should submit head chamber volume. 
  • 3mm deeper valve reliefs accommodate most performance cams intake and exhaust
  • Larger diameter intake valve reliefs will accommodate up to oversize 47mm intake
  • Standard 38mm exhaust valves are the best combination for power.

This piston set includes standard wrist pins (109 grams),and conventional Ring Set.  You should consider the following upgrades.  (Specify Upgrades in "Customer Comments Box" when ordering on line from website):

  • Upgrade to light weight pins (77 grams) for an additional $80.00
  • Upgrade to Total Seal gapless second ring set for more HP.  $133.50 extra
  • Upgrade to Total Seal gapless top ring set for even more HP. $169.75 extra
    (check out HP gains at
    Total Seal HP Gains)
  • Ceramic dome heat coating and Teflon skirt coating $188.00 extra.  Dome coating holds heat in combustion chamber for more power. This ceramic shield prevents heat transfer to the underside of the piston and reduces oil temperature. Reduced skirt friction decreases parasetic HP loss.
  • Teflon skirt coating only $108.00

If we do not stock the appropriate compression piston for your engine needs, we will be delighted to help you with a special order set. We also sell single pistons and pins if you damage one and need a spare.   Please call us for more information. 1-800-552-ALFA.
