Finally got to dyno the old truck

[RDusch]

Went to the Claremont Diesel Round up today and put the truck on the dyno jet, i ran the truck tuned like i drive it every day, no pre tweakin.



Max HP 275. 9 @ 2000 rpm and flat lined up to 3000 rpm

Max TRQ. 646. 6 @ 2100 rpm and dropped off to 450 at 3000 rpm

Max EGT never over 1200 degf

MAx Boost 32 psi, i can easily make 38 psi on the street i know whats up there.



All in all i'm pretty happy with the numbers all three runs where almost exact, i was hoping for a little higher torque numbers, but the seemed to fall in line with everybody Else's, double HP plus 50 -100 pounds, so it looks like i need to do some more toonin... .

Nice work Rick



Don't be too concerned with having less boost on the dyno. You will see less boost on a dynojet than you do when running on the street. The dynojet does not load the engine down as much as the mass of your truck does. As for the EGT you see, that does not mean too much. The reason you see such a low EGT at full power on the dynojet is the run is over so fast that the pyrometer doesn't have enough time to react to the temperature change. A load type dyno is a different story though. I'd like to have a run on one of those sometime
