WTF! Did you lack oil in your car? It looks that way. I see high friction. That must of been scary at 140mph...

 

not lacking oil at all, just ridiculous high engine load at that rpm and boost level.

it left 2 nice holes in the front of the block, one of them "I" shaped like the cross section of the rod. the rod was poking through until i was poking it and it fell back into the engine.

 

 

haha nice. what kind of fuel management? how much timing?

 

SMC with 450s, running an MSD BTM set at close to 0, stock timing. the ring lands are perfect, so it wasn't detonation

 

OOPS

 

man that sucks, well you now have an excuse for an upgrade, like a d16 or b18. at least it was only a d15. Is your exhaust wheel ok?

 

time to bust ou tthe JB weld. nice one.

 

im not sure about my exhaust wheel

 

thats crazy

but couldnt detonation with too much timing have caused too much stress on the rods w/o cracking the ring lands first? how would you keep this from happening again, other than 5th gear pulls?

 

do you have a good idea of what happend.

 

its kind of common consensus that the b7 will only take up to around 200whp before the rods just let go...

at 10psi he was probably getting close for quite some time at that speed

still.. its a bummer

 

stock rods?

 

I paid $40 for that engine, a hydro tranny, and engine wiring harness from a 93 civic. thats why im not mad.

But i am upset because my car sat since last august until i got it running and drove it for a week, then i only had my turbo on for less than 24 hours. Although I did walk my friends modded supercharged vw g60 corrado.

I think I'm gonna stop doing top gear pulls/top speed runs

and yes, i had stock rods

hehe, yeah, I think thats where the majority of honda blown motors come from.

bummer though, cuz those runs sure are FUN!!
probly bets to see where it starts to top out and just leave it at that.

 

'lil bit of jb weld will patch that right up. haha...... big ouch

 

lol same thing happened to me 2 years ago... does the oil was covering your windshield lol after the engine blow I had to start my wiper to see lol ...

 

Oh please.. Thats nothing.. ..

My d15b7 did almost the same thing.. Except the hole in my block was alot bigger and there was also a hole straight through to the back of the block..

On my motor it ripped the wrist pin out of the pistons but the rod was broken in half and not in pieces like yours is..
