OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

ACN Super Squish Pistons, 94mm Bore, 22mm Pin, "A" Pin Height (1.558")
ACN Super Squish Pistons, 94mm Bore, 22mm Pin, "A" Pin Height (1.558")
 
ACN Super Squish Pistons, 94mm Bore, 22mm Pin, "A" Pin Height (1.558") is the finest forged racing piston available for Aircooled VWs. The top of the piston has a 4.3cc Positive Displacement Dome which is engineered for maximum turbulence in the VW Type 1 combustion chamber! This results in a very "detonation resistant" chamber (not detonation proof, you can make them ping it's just more difficult to do). This piston uses the "A" pin height, which is best for 69-76mm stroke crankshafts.

The first generation of these pistons were developed for NASCAR in the early 80s; we simply transferred that technology to our beloved aircooled engines. Price includes (4) Pistons, (4) Wrist Pins, (8) Wrist Pin Clips, (4) Sets of Rings. CYLINDERS ARE NOT INCLUDED!

These are custom made from Wiseco piston forgings, every detail was incorporated into their design. These are 40g ligher than the forged Mahle piston. Strutted Piston Design (Slipper Skirt) means a shorter wrist pin, which is lighter and stronger than full wrap-around pistons. These pistons will live beyond 9k RPMs, other engine parts will certainly fail before these will!

Super Squishy Engines are known for their High Compression Performance, but you do not have to run high compression to achieve the benefits of the Super Squish Piston; the engine will run cooler and more efficiently compared to flat top pistons. Engines equipped with these pistons will require SIGNIFICANTLY LESS IGNITION TIMING than conventional engines, so ignition curve re-work will be needed to optimize results. Super-Squish Engines run cooler too, since combustion is so much more complete in the combustion chamber, instead of finishing in the header! Many racers have found they can "Hot Lap" in Squishy Engines that would have had a nuclear meltdown previously! Some street engines run Power Pulleys to get engine temperatures up to "Operating Temperature", but understand we ALWAYS recommend that your engine have full tin, cooling flaps, and operational thermostats!
