Doggonit I have used a formula to calculate redline that Don D had given 
us. Of course I can't find it right now. My redline calculates at about 
5300rpm's. BUT of course I run it up to 6K regularly and it turns better 
times that way. However, the formula shows the redline for hydraulics as 
higher than for solids. Gary P will know this formula I'm sure. I think 
it had something to do with the cushioning effect of the hyd's ?? Maybe 
that formula is in the 'Old Reliable book'?
