On my stock engine with an ecu Flash. I went to the track and with just the secondary rev limit turned on.

"Two Stepped" and banged the second rev limiter at full timing (5500 rpm) for too long and sent a rod through the oil pan and cracked the block.

Car felt like it fell on its face then picked up (didn't know it had blew yet) so i revved it out through the 1/4 and about 80% way down the track everything let loose and white smoke everywhere, engine shut off. I couldn't even see in front of me.

I think i still ran a ~14 or 15. Prob 15 don't remember.

Haven't been back since.

 

When a track guy goes car bowling:



1st run 2.3 60ft. Lol

At least my traps where consistant.
