if its a 466e good luck getting ANY power from ANY IH dealer. These engines are very prone to scoring cylinders so be carefull with the power upgrades."įorgot who wrote that on pg 1 but they are on crack. "To get more power aftermarket would be the way to go as it is very expensive to have the dealer reprogram for more power.

your milage will actually increase but obviously reliability/miles between overhauls will do the opposite you will have to then figure out what turbo/turbos (if you want to run compounded twins the thing will want to burn this excess fuel.

if its a p-pumped motor (ngd) (new gen diesel) i can build u some inj n tweak the pump to any hp/max rpm you want. I thought all the '97's were NGD? (low press mech inj). Keep in mind that gearing plays in here, some are geared for hills and 65 or so is about red-line on the engine. If I had a 4900 in real good shape and drove it ONLY long hauls I might set it slightly higher. Generally towing equipment trailers at 85 mph is not safe and rakes havoc on the brakes and tires.

One of my clients in south Florida has all his F-250's set at 75 and all the 450's set at 65 because they all tow equipment trailers. ubbthreads/images/graemlins/smokin.gifīTW on that same subject you can also bring in your F-250/350/450 and the Ford dealer can set your limit lower if safety and maintenance concerns you. We have a few retards driving for us and if we set the limit at 75 they will drive 75. FWIW, we have 12 of these trucks and our own tuner program and we have set all trucks at 65 max speed. You can also go to the dealer and he will set it for you along with other parameters including desired idle speed and even more power. If you have access to the Navistar program and the laptop hook up it's pretty easy to set the limit at any speed you wish. Not looking for much on power just 25-35hp and 50-75lb tq mainly move the limiter to 75mphĭepending on the gears a 4900 with 195 or the 210 can do 75 easily. 65mph can get you killed on the interstate in alabama. Main reason would be to remove the limiter penske had installed on it when it was theres. Is there and chips or tuners out there for these trucks. Keep in mind that there will be certain exceptions and the possibility that certain model year engines were carried over despite the launch of an improved product, therefore the aforementioned dates may not apply entirely to every application.I just picked up a 02 international box truck with the 195 or 210hp engine in it(have to check on which one). Early engines featured a 2 valve per cylinder head design, while HEUI models were upgraded to a 4 valve per cylinder head design for favorable airflow characteristics.īeginning in 2007, the DT466 namesake was retired in favor of International's new emissions compliant engine family designation and the engine was renamed the MaxxForce DT - the current model engine continues to use this name. All engines 2003 and prior featured a standard fixed geometry turbocharger. For 2010, a twin sequential turbocharger system was employed for further improvements in throttle response, overall performance, and reduced emissions. In 2004, International Navistar introduced the EVRT (electronic variable response turbocharger), a type of variable geometry turbocharger (VGT) that controlled and adjusted turbocharger A/R per operating conditions in order to reduce lag and improve overall performance. Likewise, the HEUI injection system was first introduced for 1994, although these engines coexisted with mechanically injected engines for several years. The P pump DT466 was actually used in select applications through the 1997 model year, but these are uncommon. All 1996 to current models used an HEUI (hydraulically actuated electronically controlled unit injector) fuel system. More specifically, the 1984 to 1992 DT466 employed a Bosch MW injection pump, while 1993 to 1995 models featured a Bosch P pump. DT466 Model Year Changes, Variations, and Design Progressionsġ984 to 1995 models featured a mechanical injection system.
