This is really not a question, just to pass-on my findings. Maybe it will help others.

The Mustang is a 91 LX Hatch. Incon twin turbo. She always ran a little hot (around 200 deg.) on the highway. At first I had a Howe aluminuim radiator 19 x 26 with 2 10" electric fans that cooled pretty good but was not enough.

A friend had a Fluidyne so I put that in with 2 12" electric fans, she ran 5 deg. hotter than the Howe. At this time I was getting upset.

In went a Howe 19" x 28", same 12" fans on a shroud, new stat, new heater core, and a Flow Kooler water pump. Damn (sorry) she ran 220 deg down the highway.

Out came the stat (Stant) in went a Mr Gasket stat, she cooled down 10 deg.

Ok, ok a call to Flow Kooler. "Well you have a air bubble some where it can't be our pump" That pissed me off! (sorry again!)

Off came the Flow Kooler pump in went a Kragen new pump. And guess what happened, 195-200 deg in the drive way, 190-195 deg out on the highway. Oh-no it's not our pump!

Anyway I'm sold on Howe radiators and Mr Gasket stats. As far as Flow Kooler, we are not amused!

Oh and by the way, the Kragen pump ($28.95) is the same pump you get from Flow Kooler ($86.95) just without the .25 cent plate on the impeller

Hey Tony, Great News! Glad to hear you have that little snag behind you. So now, we all want to know,.... whats next on your list of mods?

Are you going to make the Cruisin' for a Cure Show next weekend?

I have had great luck with Flowkooler pumps.

FlowKooler took care of lower rpm and lower speed heat problems. Problems out on the highway are probably your radiator or one of the other things you changed. Isolating the cooling problem is a rifle not a shotgun approach.
