Let's separate a few basic things here---
First, If you said don't go above 6500rpm---I can't /won't comment
Why go above the max power rpm? Again, you would do this as that downward trend of the hp/tq curve is just as important as the upward curve toward the max---It will give you the basis for shift patterns / gear ratios---go past the peak rpm so on your upshift the engine doesn't fall too far below peak---if you need more explaination about this I will be only happy to help you understand it, but I am assuming that the idea of your build is to replicate a road racer---
You haven't said what type dyno he used---if you don't know, ok, if you do know there are some differances--On a Mustang dyno you enter certain things into the program and come up with a test window---during the run it will say on the moniter that it is running thru test, once thru the test it will say test ended---IF the run continues beyond the range it will say so--
Things to moniter---the operator will be monitering the dyno read out, not the car instruments--he can't look two places at once---so if your vehicle loses
oil pressure someone else would have to notice it--
So you had a steel crank--what
oil system, rods, pistons???
If you where running oem rods you were way over the bar way before 6500rpm--
We perform dyno services on several dynoes in the Chicago region and quite often do 3-5 on an average per week, sometimes multoples at the same location---My son, Corey does all the electronic tuning on the Nickey Camaroes and other builders cars, plus we are often recommended to Diablo and computer tuners customers to solve/straighten out issues--there are two Mustang chassis dynoes located in St. Charles,IL and other Mustang and Dyno-Jet facilities that call us out to help them out with the more complex vehicles.
I do the carb/ignition cars and on the computer ones while Corey is into the computer I watch over the whole test for issues such as smoke, leaks, temps,
oil pressure, etc---
I'm sorry that you lost your engine, but also some were all over the dyno operator without knowing anything about what is involved in running a test.
