[Nick_B95GT]

had been spraying 175..but anyway

car left the line strong got into 2nd and thats when the carnage began, you can hear some racket and then it got a little worse, i shifted into the 3rd the car instantly shut down and coasted the last 200-250 ft of the 1/8th mile track, clocked a 6.92 @ 87mph,

any input on what you think may have let go before i tear into it

filmed with a gopro,,may need to turn the volume up or put on headphones

Sounded like some hardcore detonation to me... Rings/piston/block/bearings'ish

 

[FineLineMtrSprt]

Could be anything and just like kcsvt said...rings..pistons..block..bearings....or all the above and then some lol

Definitely bottom end.

Best case it ate the plugs. Worst case burnt up pistons and some of its neighbors.

 

[lucheski]

Check the plugs, post some pics of them here if you can

 

[Nick_B95GT]

thanks,,i hope to get the car in my garage tonight and start the tear down, ill post up any major carnage

 

[FineLineMtrSprt]

Is it leaking oil or coolant? If not the block MIGHT be ok.

 

[Nick_B95GT]

not leaking any oil or coolant,,nothing out of the ordinary anyway

 

[deadpres]

[t01lightning]

Detonation. Singed pistons and rings may be toast.

 

[itSSlow98]

Bye bye ringlands

 

[VirtualSVT]

really hard to tell from that audio.

 

[CobraBob]

I hope the damage is less than you fear. Keep us posted. Your car sounded really nice off the line.

a little update to clarify the situation so you guys dont think i just decided to spray the crap out of my car,,the 351W in my car had the bottom end rebuilt in 1989 with aftermarket truck crank, rods and pistons, the motor was previously in zephyr that ran 6.50's on a 250 shot, the motor got yanked out and sat in a garage for years til it was dropped in my car 4 years ago by the previous owner of my car, i recently had been spraying 175 with 8* of timing pulled car had ran a best of 6.84 on the 175 shot, well this night i decided to try the 200 hit, and this is the destruction, the motor was long over due to be rebuilt, surprised it lasted this long

the pass in the video the car cut a 1.57 60' off the footbrake ran a 6.92 coasting the last 200 ft or so and trapping 87 mph

# 2 cylinder

found more fragments in a couple of the other cylinders from the busted piston
