Under head milling reduces weight to 355g
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.
We have been working with the people at JE on our pistons since
1978. Through our racing engine research and on track experience we have
continuously modified our designs for better performance. We won four
SCCA National Championships using the same pistons you can now buy off our
shelf. Professional engine builders all over the world use our
Compression of 11.5:1 is measured with standard head of 112mm height
and 1.4mm Reinze gasket. (For Fuel Octaine Requirements go to "Additional
Product Information" Section)
Deeper valve relief to accomodate most performance cams.
Larger diameter valve reliefs will accommodate oversize 42.5mm
intake and 38mm exhaust valves.
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.
We also offer these as Piston/Liner
This piston set includes standard wrist pins (109
grams) and conventional Total Seal Ring Set rings. You should consider the following upgrades:
- Upgrade to light weight pins
(77 grams) for an additional
- Upgrade to Total
Seal gapless second ring set for more HP. $133.50
- Upgrade to
Total Seal gapless top ring set for even more HP. $169.75 extra
(check out HP gains at Total Seal HP
- 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
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
