Man I would hate to re-tire that beast.

Do modern diesels have electronic rev limiters like gas engines? The popping out of the exhaust like it was having spark cut, on an engine which shouldn't have spark at all, was odd.

I thought the same thing.

I assume that was a mechanical CAT 3406 A or B mode. It could be a big cam Cummins mechanical as well. Pump wide open and timing advanced to the max.

I believe the pop was spark knock due to advanced timing.

Modern engines use fuel and timing to govern them some as low as 1500rpm.

How does a diesel spark knock?

How does a diesel spark knock?

Detonation is just that regardless.

You wanna be the chick working at the shipping yard?

I mean, if you want to go with steel worker...

Some of the thread on those drive tires is 1" deep. They'd last a while.

I paid $3,300 for Goodyear drives last week.

It’d be funny if it wasn’t so sadly true

The exhaust popping is more than likely from a water/meth injection system at full blast, high concentrations can cause early detonation in diesels

I was wondering about that, or maybe propane injection? I don't know much about diesel performance.

Except the price is never OBO...

I know what I got! I don't need to sell!

It could be propane, but propane compresses. So thats why im guessing water/meth. The mixture doesn't compress so therefore changes the compression characteristic in the chamber and can cause early detonation. It also does a good job of controlling EGT and Intake temps on builds

Weird... Water/meth is used to decrease detonation in gas engines. Odd how things change when you double the CR.
