As title says got 2 of my rods come through the block at the track! probably a stupid question but could this be caused by bad ignition timing? flame away! thanks for looking

 

D-series have longer rods and the so rod rotation angle is greater and increases the chance when the rods snaps
"KABOOM" hole in block!

But since d-series have longer rods it also makes more torque than B16's since B16's rods are shorter.

In the end longer rods makes more torque but increase the chance of making a hole in your block when it snaps. That's why you need to use very strong rods and due to the increase in rotation angle the piston rings & walls have more stress too.

Don't under estimate TURBO SOHC VTEC!

 

Yeah! Too much timing could of been the cause too.

 

good info cheers dudes

 

yeah d-series may make better tq due to the longer stroke, but last time i checked torque doesnt make up for hp

Ummm..I think you don't know your math....
You have to use torque to calculate Hp....torque is rotation force...

oh really, i thought torque was just a movie

 

^"confused! scratching head"

What the heck are you saying, rod stroke gives you a sign on rod angle- short rod long stroke motors.

I would rather have long rods over anyshort rod for the purpose of more power.

 

Yeah... Think about the geometry. Longer rods would mean less rod rotation angle. There is almost no ill-effect with long rods, so you should always use the longest rod that you can fit that still gives you enough room for the wrist pin and ring pack.

Thrown rod means something either failed in fatigue or due to overstressing. Doesn't really mean the ignition timing was off, that tends to simply melt things.
