With all the idiots 'rollin coal' around my neck of the woods in their absurd trucks, I'd like to reciprocate with an enhancement to my sensible, stock-height grandpa truck ('87 F250 IDI 6.9 Liter).

Anybody explored water injection into the exhaust for brief but billowing clouds of steam? I'm thinking that sure, it'd increase back pressure and actually hurt performance during use, but not enough to damage anything if done judiciously.

Initial idea is to weld in a bung to the steel downpipe after the exhaust manifold, keeping the manifold nice n hot and avoiding any thermal shock to the cast iron, using a water/methanol injection nozzle and pump on a momentary switch.

Having a valve and controller to use water injection for economy or occasional steamrollin would be even more fun.
