Not totally true. If you look at the activation rpm and the MAF compared to timing you'll see at wot it started at 26* and stayed there through the ensuing torque build up and didn't drop down till much later in the pull. This is where i believe the ring land went bye-bye, and then ensuing melt down. I think some how I added timing instead of pulling it, and even later when it shows lower timing that's with 1.5 degrees pulled by computer (KR), eventhough the histogram never showed a thing.
Maybe you should have lifted when we were all waving our arms at you![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
Ya think so.

Robert. it is easy to read the map you have there. You see the scale across the top? That is RPM
makes the rest pretty clear. Not picking on you really. I just tune enough to know where to look
I will say even in that area you seem to have to much timing ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
Think we could put at least one wet stage on the car? I am sure I could get Dave to give you a deal on a good DP kit. I would even Sponsor part of it

DP, I don't think so. Waiting on the new innovative Dry system coming to hot rodders everywhere. Stay tuned.

I know how you feel about dry but if you change where you are shooting it at....
Well any way get that thing up and running again already! BTW buy the rest of the cage now...then your car won't be down later like mine is now![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)

Yea, been thinking about the cage. The vettes are a real pain in the azz, and don't know if I want to tackle it.

wow robert that sucks.. sorry to hear it.. I like you know what kind of borrowed time i'm on
i've been hitting the stock bottom end with 300 wet for a while now.. at 24-26* of timing.. but mine was with tr7ix plugs.. might be my saving grace..
car is currently down getting a built 4L60 but compression and leakdown are still near perfect..
well onward and upward we go...

The only reason mine reads 6lbs higher is I extended the top of the table where it flat-lines on f-bodies.
Glad you found the error though sorry about the the way you had to find it.
Here's to bigger and better next time.

Tuning, tuning, tuning is key. Even your boosted car maxing the MAF at 550hp and going way rich is tunable and you have a false sense of the MAF being maxed out when in reality it's your tune.

I bet you never make that same mistake.. Screwing up is how I have learned as well. Nothing like hands on experience.

I'd say the plugs were likely the biggest contributer to detonation and hence the destruction of your ringland(you didn't have sparkplugs you had GLOWPLUGS

Im glad you found out exactly why your engine blew.
This way you wont make the same mistake and you know now it can take more.
Im suprised how much those hyper pistons can take.

It's not the tune (well it kind of is, I'm working through 2bar tuning now) .... I don't have a supercharged car; my boost level isn't bound to RPM. I can make 16psi FAST at 2K in 5th gear, and will be out of first before that psi is made... Once the MAF reaches that peak, all you can do is cheat numbers in PE.
That's the point I was making. There is NO automatic adjustment of fuel once it's maxxed, only what you have preloaded into a table.

your 100% correct robert its ALL in the tune.. i run my car VERY rich on the big hits and a good amount of octane..
but i won;t be doing all that anymore..
i'm going boosted..
