Diesel Dodge Dart Concept

I've done one mod only to my CTD and TST claims/warranty's no less than 250HP/600Ft-Lb for that mod, so that is all that I claim. I know others aren't, um..... as conservative with their claims.

I'm rather surprised by the volume of trucks that get chassis dyno'd in that realm. I'd venture that it happens a lot more there than anywhere else. The partial problem with that is, in spite of various claims to the contrary, there is no direct way to go from W-HP to F/W-HP. So F/W-HP numbers based on W-HP dyno results are frequently bandied about, but lack any substance.

That said, if someone else's truck had mods X, Y, & Z, and you've copied all of them in the same truck then it's reasonable to expect that your power is about the same as their dyno results. No two engines make exactly the same HP even if all of their parts are identical, but barring any glaring issues +/- 10% is reasonable.

I'll state the obvious, diesel engines drive differently than gassers. If the driver doesn't adapt to them then the results won't be very good. Can't drive a diesel the same way that you drive a gasser. It'll work and you'll there, but you're not going to be getting the total performance (power & mileage) possible from the diesel by driving it that way.

As I've stated, in this thread I think, if the / currently in the Valiant doesn't ultimately offer the mileage (mid 20's average) and performance (~130-150 HP) that I'm working towards and someone hasn't yet convinced me to part with it, then I'll be looking at a Mercedes turbo-diesel options. Out of the box they're about where I am now, plus a little. A good pump man should be able to put me where I want to be w/o having to really lean on the engine too hard. Won't be inexpensive to do that, but I didn't buy this car as a financial investment. I bought it to drive to work and to have fun with. I've set goals for it, now it's up to me to see what I have to do to meet or exceed them.
