Engine variants

Why is there zero discussion about the uprated versions of the T700 that have come out? We're at the -701D going into the UH-60M, and I've seen reference to a -701E as well. --THE FOUNDERS INTENT ^PRAISE 11:32, 30 September 2009 (UTC)

Because no one has done it yet. Care to help? - BilCat (talk) 12:48, 30 September 2009 (UTC)

The Apache Case Study report that Founders found has some info on the T700 from page 10 to 14 (study page numbers). -Fnlayson (talk) 18:21, 1 October 2009 (UTC)

And the YT706 engine based on the CT7-8A. This is mentioned in article already, btw. -fnlayson (talk) 03:45, 22 November 2010 (UTC)
