Description
The Concept
Develop and provide New High quality Corvair crankshaft as a replacement for the GM crankshafts in all applications.
Why This is a long list, with many things to consider. First – any Corvair crankshaft is at least 50 years old and we have no real idea of many factors: 1. How much time is really on the crank 2. How was this engine treated 3. What is the metallurgy of the crank 4. Was it repaired or reground in the past A new crank shaft of known origin would answer these questions. Second – Corvair engines were produced in a cost constricted environment.
Our primary goal is to offer a replacement crank that will require no major changes to the existing setup to install, while maximizing strength and service life. Second to that goal is to keep the cost down as much as possible. THE BIG QUESTION “DO I NEED ONE” This is what everyone asks, but there isn’t a definitive answer for that question. You have to ask yourself what your guideline of acceptable risk is. The circumstances listed below should be the guidelines for running a stock crank:
*** Any “trauma” to crank like a prop strike (regardless of magnitude), or a balancer issue etc would be cause for replacement.*** With the above guidelines the re-manufactured stock GM crank should perform well and have an acceptable service life for most users. All that being said; if a new manufactured, extremely high quality crank as above is available, we will use one. If the new crank cost $1500 more than a reworked stock unit then it is well worth the money and the Vair would still be an excellent value in the 100 hp engine market! |
