That is an awesome collection of engine recordings!I have this, but I don't know how to post it here.
Not sure how large of an audio file it would be, but if it were converted to MP3, it can be uploaded by way of the Advanced Reply, under "Manage Attachments".
Audio files acceptable to upload are: MP3, WAV and WMA
