240 whp 2.0 LS/VTEC. Done.
 

This is what detonation looks like and how it destroys a brand new fully built engine in less then 30 miles. Apon detonation, the head lifted up off the block, and blew metal into all 4 cylinders.

ouch. whats the plans now

Re: 240 whp 2.0 LS/VTEC. Done.
 

What was the root cause?
injectors to small?
fuel pump failed?
fuel pressure n/g?
bad tune?
Fill us in, so others may learn.

Re: 240 whp 2.0 LS/VTEC. Done.
 

Boost FTW. Bottom end is GE knfie Edge crank, sleeved, Eagle H beam rods, everything excpect pistons are perfect, can still see the hone.

The reason this happened is becasue this store lied to and sold me 108 ocatane when I need 110 because he hates imports. So yea. Tune was great. Just the asshole who sold me the fuel.

what was your setup and compression?

Re: 240 whp 2.0 LS/VTEC. Done.
 

It also looks more like a dropped valve than detonation to me.

Re: 240 whp 2.0 LS/VTEC. Done.
 

dump the pistons, buy a 895 dollar endyn head and an AFI kit and youll have a turn ket 500hp car, or a buckin bronco rodeo ride, however you want to look at it

X2

Re: 240 whp 2.0 LS/VTEC. Done.
 

Yea, it deff did. We are looking into if it just dropped a valve, or dropped a valve due to detonation.

Re: 240 whp 2.0 LS/VTEC. Done.
 

i dont thing the 2 octane point difference caused that since the points can vary up and down by a few, something failed in the motor like stated above

Re: 240 whp 2.0 LS/VTEC. Done.
 

That cannot be from 2 octane points.

Re: 240 whp 2.0 LS/VTEC. Done.
 

damm!!!

Re: 240 whp 2.0 LS/VTEC. Done.
 

****kkk man, was it tuned with confidence?

Re: 240 whp 2.0 LS/VTEC. Done.
 

Yea, I forgot to state in the orginal post, that we are leaning more towards it dropping a valve, but how would every cylinder have metal shavings in them when all they are all fine? Thats why we are curious about the whole detonation

Re: 240 whp 2.0 LS/VTEC. Done.
 

i dont see the head lifting enough with 240whp to allow metal from one cylinder to get to all 4. Did only one valve head drop?

Re: 240 whp 2.0 LS/VTEC. Done.
 

You don't drop a valve due to detonation.
The pictures shown are of a motor which was destroyed due to a dropped valve....

Re: 240 whp 2.0 LS/VTEC. Done.
 

man with all the engine failures i might have to get back into the engine building business, looks like most of the people that do it now just plain suck.

Your intake manifold did that to the rest of the cylinders.

Order in the next 10 minutes & get a free broken retainer!


Back on topic.... Sorry to see the destruction of your motor due to a piston to valve or valve to valve issue... Could have also been a faulty retainer install etc.

Re: 240 whp 2.0 LS/VTEC. Done.
 

Again, what was your compression?

Re: 240 whp 2.0 LS/VTEC. Done.
 

Sorry for your loss. If you post some actual details of the build we may be able to help you figure out how/why it happened so you don't do it again.

What cams?
What valvetrain?
What compression?
Were v2v and p2v checked?

Excuse my ignorance...how?
