it was a relitavely new international.... new enough that it was turboed.

 

The old N/A NH220 cummins, when the fuel pump was set right under a really good load would blow a 8-12 in pretty blue flame out the stacks. Late modle trucks wont do this because of the turbo and cooler exhaust, If it's on fier it's usually bad turbo seals dumping oil into the exhaust or a bad injector dumping fuel.

 

Diesel Central has some new vids up---the huge one shows a bunch of pulls and near the end, Big Bad Dodge pulls at night and you can see blue/green flame from his stacks--pretty awesome, but it's plain to see he broke at the end of the run, so maybe not so cool. If you have a high speed connection, it's worth it to check out...
