twin DPF's on semi

[dieseldan2005]

Have you guys ever seen a dual dpf setup? Here is a retrofited 1989 international 9370 with a 3406B cat that is in california to be CARB compliant. Looks a little strange doesn't it?

Does look weird, if they think they're gonna get $31K for a 1989 IH day cab, they're out of their mind. What's even more funny is, that engine combo doesn't have to be complient yet.

I don't see anything about DPF's in the ad?

It does make me wonder about a dual (or more) DPF setup on our trucks... Less resistance=more power right? Regens sure would suck if you had to burn off multiple filters though.

I have also wondered about high-flow aftermarket DPF's...

They might get that in CA for that truck but not here in the midwest. Star what is hte cutoff on the engines that need to be in compliance? I have seen 2 trucks with mechanical engines that had retrofits on them for sale on truck paper. Also there was a company called mine-x that was supposed to be making free flowing dpfs that were a non wall style. Meaning the flow didn't get blocked like all the current ones used. I honestly wouldn't be so annoyed by emissions stuff if it would flow more and allow for more sound. I miss my straight pipe on my 7.3.

you want to hear something funny, Caltrans is taking the burners off there graders they use for plowing snow. the last three years all the new JD blade had the burners on them, this year regular mufflers.

How are they getting away with that? Are they realizing that their fuel costs have gone way up? I heard JD farm equipment was horrible for fuel consumption since the DPFs. Farmers have been really complaining.

Because Cal Trans doesn't have to follow the rules, or any other gov. office for that matter.

For info on compliant engines, search CARB Truckstop, it lists the regs.

Its Ridiculous. We have two DPF/EGR equipped ISX Pete Dumps, and we call them the Terrible One, and the Terrible Two. Or the simply, the Twins.

They have nothing but problems related to the emissions systems. They are tied with our Autoshift Pete's for total downtime, and the autoshifts have 75k more miles on them.
