check this out, i hope the attachment worked

just wanted to clarify the explosion that took place. there was a upside down car at the end of the backstraight. I hit him full throttle!! His car had nothing except frequent flyer milage lol!!!! the head and sleeve stay attached to the car by the muffler springs and the carb. was held by the fuel line and the back plate was there with the two lower screws. the crankshaft and the clutch and gears were forward thru the fence 40 feet from where the car landed. We still have not located the piston and conrod but someone heard something clang the bleachers at the begining of the straight. who knows maybe it will turn up. got jb weld!!!! loll!!

IT HURTS JUST TO LOOK AT IT

Those must have being flying everywhere.
Next time I needed to look for parts at the track, I call u

quite true, we found some the next day and sure would like to locate the piston just curious to see what it looks like

The death of a beautiful engine....

I think they get at least one of those a year in ft myers we will probaly see another at the winternats in feb

heres the car picture except the crank and gears weren't on it

Speedy
OMG that is exactly what happened to my car in 2002 at fort myers. same scenario exactly and the RB in my car looked just like that.Except it was not in the car any more. Just the bottom of the case. wow thats like deja vue.

Dave Cambell got it that way in 02 to.

that doesn't make me feel better, but i know exactly how you felt that day. i'm defenitely over it now and just smile when i think of it. there is one lesson to be had from the experience, when your on the drivers stand and waiting to be marshalled even if you think your off the main driving line, always let your fellow drivers know where you are. REAL LOUD!!!!

Every once in a while we will see pictures like that, usually all 21 big blocks, and usually (almost all) are cracked/splited at the same SPOT on the case....and all are during hard impact (someone get nailed or nailed by someone)

I am wondering....what made the IMPACT so bad that will cracked/splited the case all the time...? Is that the internal PRESSURE from the nitro exploded the block like that...? Not really the IMPACT but pressure inside..?

I hope that won't ever happen to me ouch!

Sorry to see that bro, seems like .21 engine's case is too soft / or bitter?? heard of this happen to our local racers too. But not the .12.
By looking at the pics, it doesn't seems like an explosion. The case cracked unpon the huge impact.

Just because the cars are not that big, it doesnt mean then inpact force is not big. The cars are probably traveling at around 70-80mph or more, and the cars carry a lot of mass behind them. We see how small the cars are and think the inpact can not be that great, but its an incredibly big inpact. Add to that the fact that cast aluminum is rather brittle and you get what happen to that engine. The .12 probably dont have that happen because TCs use foam bumpers, therefore minimizing the force of the inpact. 1/8th cars dont have foam bumpers, they just have that plastic bumper that transmits the full force of the aluminum chassis behind it.

I still dont know of the engine that broke is the one on the car that got hit, or the one on the car that did the hitting.

That is exactly my question, it is very odd that the ENGINE is the one that took the most force from the Impact (compare to parts like chassis, arms, and bumpers...etc) but my guess is NOT really the IMPACT cause the split of the block, it is the internal pressure of those 2.8HP + engine that break the case themselve....simply exploded....kinda.
