Min/Max Password Length

I'm working on script to do my combination tests and I was looking to narrow down the size of the words going in.

My if statements for ocl/cudahashcat restrict that to 8-16 but I can't seem to find what the upper limit is for hashcat itself. The wiki shows a min but no max http://hashcat.net/wiki/doku.php?id=hashcat

The plan is to bruteforce 1-8 then use oclhashcat for 8-16 and then use hashcat for 17+.

Peace
