You have probably heard the term " OKRASA " if you've been
into vws for a long time. There are many people who do not know
what an okrasa motor actually is. This article will describe the characteristics
that make up a vintage okrasa motor, and why they are so rare and expensive. Back in the early 1950's, when VWs were just starting to come into the americas, EMPI came out with a kit, which they called "OKRASA". This kit was to beef up the engine a bit, with dual carbs, and special cylinder heads, and pistons. To put it nicely, the okrasa motor was the race car edition for its day. The okrasa motor had a compression ratio of 7.50, which was much greater than the standard VW compression. I have found some performance information in an old road and track magazine, and it states that the okrasa motor could push a vw as fast as 87 mph, compared to 76mph in a stock one. The price for an okrasa kit was $250.00 in 1956 from EMPI, which was a bundle. The data also shows the acceleration from 0-60 increased by three seconds. Horsepower on a stock VW is at 36@3700rpms, while the okrasa was 46@4200rpms. As you can see, the okrasa kit was a nice way back in the 50's to make your VW a little peppier than the rest on the block. The price of these kits are outrageous today, considering prices on eBay have risen as high as $5000+ for an Okrasa motor. If you find an old okrasa motor, it's worth a bundle. Snag it, and store it away.
