No way there should be enough pressure built up on the clutch side to blow "in" the seal.
Check the 2 clutch snorkel tubes, make sure they are clear of obstructions. Even if the exhaust was plugged up, all it would do is reduce the air flow to zero and overheat the clutch and blow the belt.
Calling Speedwerx might be helpful, but if you don't have speedwerx products in your clutch then they probably wont give you any helpful info.
I'd be carefully running at any speed or for any length with your clutch cover off. The primary has a support bearing in the clutch housing and putting stress on the primary might damage the primary assembly shaft.
This is definitely a perplexing problem.
