C13 vs. C15 ?

We were looking at buying a couple more tractors and most of the used tractors that we were looking at have 430 hp C13's. We already have 2 C15's that we haul with that are rated 435 hp. I realize the C13 is a smaller engine. At those ratings for each engine and the trucks being '03 freightliner columbia's for the c15 and '05 columbia's for the c13 and both 10 speeds, would there be much difference in pulling power/torque if we are at 80k gross with a 12'6" high steel gondola trailer behind it? any info would surely be appreciated. Thanks guys!

Just assuming the '03 C15's are MBN's (single turbo "bridge" engine)and not Acerts?

Personally I'd buy the C15's and have the ECM's reflashed to an older flash file. (like 6NZ) We've got both an '03 C15 MBN and an '04 C13 and while we've had no problems out of either you can't beat the power and torque of the larger engine.

The reflash can't be done at Cat or any dealer, it's got to be done by a few people on here.

Why would you have the C15's reflashed to an older flash file? Just curious.

But yea, I finally got my dad talked into not listening to the salesman who said the C13 would pull just as good as the C15 (the same salesman that last year sold us a freightliner with the ism cummins with 300 hp who said it would pull as hard as a 465 hp n14 that we had. dad believed him and we bought it. we had to make them let us return it because it damn near killed the truck and driver pulling 80k from southern iowa to st. louis. at which point he said "you asked if it could pull it and i said yes.... you just didn't ask how fast! it has no where near the power of the n14" 2 headed !@$%$# Sorry for the rant. Thanks for the info though.

I would think it would take a C-13 rated at 470 to match your C-15'S max hp on a stock 435 is already 455hp the question is what will being able to haul another 600lb of scrap every load worth to you and how much fuel would you save going back empty, those open top Gondolas pull just about as hard empty as they do full so I'm told

true... I suppose one could pull a 5.9 out of his dodge p/u. Think of the weight savings. Could carry another ton of net weight...
And think of the milage gain on the deadhead return trip.......
