Piston Set 1750 81mm 11.5 Big Valve 1mm Over, 1830cc LITE WEIGHT APPLE BITE Dish Dome
[JE81PS11.5]
$699.00 $639.00

CARILLO ROD SET of your choice, $50.00 off, if included with THIS 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.

Our 81mm, 11.5:1 1750 piston set was developed while winning three SCCA National Championships. The only change is the larger diameter valve reliefs to accommodate the vintage racers that are not confined to standard valves. The standard 80mm liners can be bored to 81mm.

  • Lite weight.
  • Compression of 11.5:1 is measured with standard head of 112mm height and 1.4mm Reinze gasket.   WARNING:  .25mm milling = +.25:1 compression increase.  Customer should submit actual head chamber volume for absolute accuracy.
  • Deeper valve relief to accomodate most performance cams.
  • Larger diameter valve reliefs will accommodate oversize 42.5mm intake and 38mm exhaust valves.

We also offer these as Piston/Liner Sets.

This piston set includes standard wrist pins (109 grams) and conventional Ring Set.
