Quick and easy way to push out a head gasket.......LOL!!

So in your expert opinion, this IS NOT the correct tune up? I just want to make sure I am not using my wonderful Big Shot plate wrong adding all that fuel.

without fuel to match it stoichiometric ratio.. they basically just put any flame/fire out in that motor...basically same as spraying it with a co2 fire extinguisher..

Exactly the opposite. They ADDED an oxidizer, not removed it. I did the exact same thing to a lawnmower that I repaired for a guy. He didn't want to pay me, so he left with a lawnmower that didn't work.

We have done that on the dyno with some pretty good results. Spools the turbo faster and clears up the smoke..............in a diesel lol.

This is one reason IF I ever have the need for some spray I will be giving Monte a call. I can't afford to do a bone-head move.

Why am I not surprised that this happened near where I live?

"without fuel to match it stoichiometric ratio"
Stoichiometric is irrelevant to tuning an engine for power except as a point of departure: find it, and go lower. 14.7:1 etc. is definitely not what you want to make with nitrous. The real question isn't rich or not, but how rich.

Just the dose of pure nitrous is not what hurt it, because without the proper amount of fuel to go with the added oxidizer, you are not doing anything.............BUT.........in this instance, as obviously they were "tuning" on the car, I would bet my bottom dollar the tune was rich. So when they hit it with all the nitrous, the tune got "clean" for a split second(you hear the motor rev)it made some real power, was over timed for that power and pushed a head gasket out.
Monte
Liquid on a MAF will usually have it read low, but the nitrous had transitioned to gas at that point and was being "counted" by the air meter so the ecu kept adding fuel. I don't think they changed the tune any, I think they just opened up the bottle with the motor at wot and hoped for the best. Unfortunately on a lot of cars timing is modified based on intake temp, so when the intake temp plummeted the ecu thought the motor could handle additional timing.
I will say I don't think I've ever seen a head gasket pop that quickly, lol.

Back on Drag Week 10 when the crew was running the Wanbulance, the alt took a dump...so they bought a cheapo gen to hang on the back bumper to run a charger.. on the last night we tried to blow up the gen, hitting it with spray.... never did blow that thing up... but it was fun trying
