How can you tell this from those photos?
If that was the case he would have had the loudest engine ever built. Two, he would have had been smoking from the blow by, cause from the rings not seating. He would have also had very low power because all of the boost would be going into the oilpan.

The reason on the roots versus centrifugal is dependent on how much parasitic losses they generate to the motor but they should have the same torque/horsepower at the wheels regardless, but any motor making 100 horse at a given rpm will make a given amount of torque... I'd be curious to see a graph or whatever proving the roots versus centrifugal difference you are pointing out.

The picture for cylinder 1 shows plenty of signs of possible detonation... or just horrible heat regardles... the question I have is why the other 3 cylinders don't seem to show any signs of it at all and are cracked exactly the same as well... that's why I'm wondering if his rings butted and then bound up and the piston slammed down on it and cracked... then because of the angle the rod would be at it pulled it toward that one side and that's why they all cracked down taht same edge.

HP is not a measured value. Torque is a force that is measured and RPM is a value that is measured, and HP is something that is calculated from torque and RPM.
anarchistchiken said:
Yes, they are both putting out the same torque at that RPM. That doesn't mean the V-8 has the same torque #s everywhere.
It wasn't that you didn't know the formula, but you tried to make the guy who put it up look like an idiot. Why would you do that even if he was wrong?

I've tried like 20 times to upload the map... heres one more try....

Couldn't really tell ya. I guess people did it to me when I was a newbie? Maybe I'm just pissed off at life in general.
Anyway, sorry I tried to make you look like a jackass dude. I should have been a lot more conservative in my response, clearly. Thanks for the education guys.
Two things:
blkZoomZoom, have you checked injector #1 yet? I wonder if an injector failure caused that nasty detonation pocking in the cyl. #1.
Also, did anyone notice that the head held together find at those huge RPMs for a sustained amount of time? I don't know about you, but I'm pleasently surprised that it didn't float the valves and smash itself to pieces. I figured that would be the first thing to go if over-revving was the killing factor.

LOL. Nick
. We've all done it at some point... I know I've snapped on Dana before and been a complete ass... and one other guy managed to REALLY get to me, which is impressive in itself LOL. but yeah... moving on... BZoom has a blown motor and we want to figure it out!

Lord knows I need help in that department, especially on the internet, where people arent real.

We should have a therapy section.
So Nick, you think detonation killed the pistons? I honestly don't know what the a/f were but I can tell you I put them to the point that it chugged and backed it off till it didn't. On top of that, this motor has never seen anything less than a 60/40 mix of 107 octane and 89-93 octane. Every week I put in at least 5gallons of 107 at the track. I then would put like 3-4gallons of normal gas and it would last me to the next week.

um.....i believe he has been corrected & appologized for this...no need to drag it along...focus on the topic at hand.

You two get along so well I know LOL
. Anyway...
I'm wondering if it WAS the rev's that killed it or detonation got it.. if it revv'ed up past that stock fuel cut/rev limit and the (extra?) injectors were dumping in per the MPI it would have gone lean and kept getting leaner as the rev's went up... then detonation would be highly prevalent.... But as I said before, Nick do you see detonation signs other than on piston 1? The others look clean... one picture I thought I saw a couple tiny little signs of it possibly, but that doesn't explain the other two shattered pistons... I would think the CP pistons could handle a fair bit more abuse than that... the race teams said the melted holes through the pistons before they actually had issues as far as strength with detonation and hot burns.
