Default Car died after 150 hit

So I changed out my jets from 100 shot to 150 shot first time spraying it pretty much lost all power when the nitrous was engaged and ran for maybe 5 seconds with no power whatsoever if that until it completely died. Didn't hear any backfire however there was a lot of white smoke coming from the exhaust im pretty sure it was white.
Tried to turn it over after letting the car sit and cranked over fine just wasn't firing at all so threw it on a trailer. Today I rolled it off the trailer and decided to try to start it she fired right away a little bit of smoke but idled fine smoke faded away after a couple seconds she seems to be running fine?
Any ideas haven't pulled the plugs yet but I will pull them this weekend.

What jets did you have in the plate, also how much timing did you have in it, what kind of fuel, and also what spark plugs are you running?

Almost seems to me like your n20 and fuel jettings were backwards..

I cant claim to be an expert though.

From what you described, it sounds like the car got a ton of fuel and very little if any N2O and possibly washed the cylinder walls. That would explain the white smoke and the car not cranking back up right away. Does the oil smell like gas?

DId it die while you were spraying or after? Sounds to me like you got to much fuel or the fuel solenoid stuck open. This just happend to me..

Yeah, check to see if the nitrous solenoid is opening and also that there is not a blockage somewhere.

nitrous jet should be a 33 not a 38 at 55 psi. It sounds like you are overly rich.

I will verify the jets but I am 100% sure I followed the jet chart. Died as soon as I went wot. If I did in fact go way to rich and wash the cylinders with gas could I have hurt anything?

If gas is in the oil, make sure you change it asap.

Just watched your video, and I can COMPLETELY relate to the "oh my god" at the end, lol. I've had the same feeling a few times.

You won't know if the rings seals got messed up unless you run a dual guage leak down test. If you haven't been running it a lot since then I doubt your hurt anything, but running the test and having piece of mind is always nice.

GENTLY remove the radiator cap and make sure:

1. has water

2. does not have excessive pressure and smell like exhaust.

3. That puff of white smoke is infamous for a blown gasket. pull the dipstick and make sure its not milkshake colored.

4. spot check all plugs and see if they look normal.

that Mustang looked fast. get out there and represent.

if you think it runs fine, id let it warm up and be sure of it. i cant see how washing the cylinder walls that bad would cause a hydrolock or anything.

change your oil
check your plugs

if you want to be safe, do a leakdown test of all 8, even though its time consuming.

thats a seep at the most, i wouldnt even worry about it honestly.

honestly that looks like oil leaking out of the intake ports at the head. look how it comes from up high on the intake port and runs down to the valley cover then toward the water pump. any updates?
