Re: Need help understanding my radiator hydraulics

Dave,
Actually, just learning what the 9000 can do as it didn't come with a user manual and Nexiq does not have any for this model any longer. Think I have about 75% of the possibilities down but trying to go carefully. Most intriguing is the duration and injector response. It can manually cut each injector and the ECU will compensate by adding more fuel to the remaining injectors or can set it to do it automatically in order. The reader will then figure the percentage of fuel increase and tell you which injector is not working correctly. What is nice is it reads the engine model, serial number, HP, Torque, ECU model, serial number and any firmware updates plus other stuff I haven't written down yet. It does have a lot of user configurable settings but when I go by these possibilities, I make sure not to change them.........yet.
Yes, would need a larger turbo for more HP. Boats use a pair of smaller turbos with the high horsepower 6V-92TAs but mostly to get more boost down low RPM as to get the boat up on plane quickly. Understand that the high HP Detroits used about 3 sets of turbos between engine overhauls. Probably lots of boost at low RPM meant overspeed on the turbo at high RPM. Did meet a fellow in Puerto Penasco with a twin turbo 500 plus HP CAT in his 36 foot Holiday Rambler. Said it was an optional engine. Only one slide so guess it was pretty quick.
I did a lot of turbo sizing with compressor maps but after hours of calculation, I never came up with the same turbo the German guy did at the shop so we always used what he said would work best.

If his cat was a 3208 twin turbo they were rated at 375 hp. Ran across a Texas 85' ftx ored owner that had bolted the setup onto his 250hp cat. Had 100k miles on it since the change.
He mentioned the trans limitation and only used it hard locked up in fourth gear on the 643 Allison. No issues.
