Went to Track Weds... Broke EVERYTHING

[90lxcoupe]

Like the title says i went to the track on wednesday. Everything was going pretty well i ran a pair of 12.1's with a best MPH of 115. So on my 4th run of the night i miss 3rd gear and rev the car into next week. The car shut down and i coasted the rest of the way to the exit. I tore valve cover off to find that ALL the pushrods on the drivers side were bent, i took the head off and found 3 exhaust valves stuck open and one of the exhuast valves was broken off and stuck in the piston

Oh man, sorry to hear that. I blew up a tranny at the track and it was one of the worse feelings in the world. Now its time to build something bigger and better.

yep definitly sucks, here's a pic of it

 

[90lxcoupe]

would this happen jsut from over revving the motor or is it likely that the valve was gonna go anyways?

thats the outcome of missed shifts and 6500+rpm with no load.

ouch

Bummer man, sorry to hear that. At least now you have an excuse to build a new motor.

Did your tranny survive the missed shift?

My buddies keep trying to get me to take my car to the track, but I haven't cuz it's my daily driver, and I'm afraid something like that will happen.

[soontobefastfox]

Hell yes... I'd be retarded not to

 

[68torinogt]

[R2D2]

if it had a stout automatic it would have went 11's and not blown up

 

[90lxcoupe]

Or a rev limiter
