Adrian's Audirac Racing modified 2500cc engine case includes high performance components designed for the ultimate Volkswagen competitions proven with endless top 3 place finishes. This page presents a breakdown of these components all done in house utilizing fabrication techniques that reach beyond industry standards.
This trust plate was designed by Adrian himself and the case machined for a custom fit; extends the life of the trust bearing by up to 300%.
This weld prevents the area behind cylinder #3 from cracking; a very common and well known problem with aircooled Volkswagen motors.
This heavy duty seal prevents troublesome leaks around the pully; the case is machined for a 100% snug fit.
These gussets reinforce the top of the case and prevents that area from cracking or breaking under extreme conditions and abuse during race competitions.
These heavy duty case bolts reinforce the center wedge and prevent it from cracking; yet another solution to an issue with competitive aircooled VW racing.
The case is machined to allow you to have both In & Out oil fittings on the side; aids the oil flow to externally mounted coolers.
These inserts have been carefully machined into place to spray oil onto the pistons, continuously lubricating and cooling them during extreme engine abuse.
The case is machined to include new case saver which replace stripped threads and prevent these problems in the near future.
Shuffle pins help prevent the two center bearings from moving during extreme engine performance when metals reach extreme temperatures and vulnerability.
A line bore is necessary to ensure an optimal crankshaft fit and overall aircooled Volkswagen motor performance.
Adrian's unique oil check valve perfectly controls oil pressure and slows oil flow through the cooler for more cooling time and overall engine performance improvement.
