My 400whp D-series BOOM... carnage pics

Don't believe I ever posted the dyno sheet so here it is.

brief rundown of the setup

D16Z6
Benson sleeved
SC61
Cp 9:1
Crower rods
1000cc Precision injectors
Hondata
Crower springs and retainers
Zex 59300 cam
etc
etc

Setup lasted 900 miles and a few passes at the track. On the 2 step in my driveway trying to solve an electrical problem this happened......

This all happened a few months ago, just never got around to posting it. We think that 2 of the valves touched. This may have been caused by valve float or spring rate/pressure failure. Possiblity that it may have been a cam but the lobes on #4 cyl look good. Haven't really messed with the junk head lately. Sold some stuff off the old setup and building a new one, still sohc

The valves chunked on pump gas, about 4psi @ 7.2k.

Also contact with each other, but that's rare with stock sized valves.

Like GITWIDIT said, it could possibly have been a spring rate failure or valve failure.

ACK!
dang man that sucks,

did it die like that on a good tune?

I guess if 2 valves dropped it musta been something valvetrain related?
You dont' think detonation had a part to it?
What do you mean by "2step" ?
Man I really wanna know wtf happened.

400whp though.. wow.

1.7L time

At first it was the 400hp that hooked me, then to see the powerband lasts over 2k rpm...

I mean were you running pump gas when you made 400whp on the dyno.

Oh and glad to see your sticking with the sohc.
