Blew it up real good. :-) where to go from here.

Yeah.. Did all the fail safe test, all the flow test, pump test, voltage test, etc. I got mine from howerton engineering. He answers his phone or calls u back every time. Super customer service. But we tested everything plus some. The system is absolutely bad ***. I have it setup to go off injector duty cycle, it also can go off boost.

i could envision them taking out a side seal but nothing else. the side seal is the first thing they contact on the way in and the side seals are still brittle cast iron with some protrusion. for apex seals, i would have to hope that a tiny piece of plastic wouldn't harm them when they can hold thousands of psi of dynamic compression.
but i have been wrong before, just about anything is explosive when hitting something at hundreds to thousands of miles per hour.
But, I too have been wrong...twice

Actually, the diffusure would first make contact with the rotor (unless it makes it through the port during full open) not the side seal itself. Even if a small piece got "scissored" off by the closing edge of the port and the rotor, then somehow got wedged in between the rotor and the side housing (past the side seal, in between the side seal and oil scraper), I still can't see it staying there for any real period of time or cause an issue.

most of the time there is neglect to mention that the engine was run previously on a grenaded turbo or had the inlet wide open.

doubt it was timing related or octane related with the AI, sounds like a chipped seal which is almost always caused by a lean condition overheating the tip of the apex seal and blowing it out with a nice sharp detonation cycle. sure he said it was in the 10's but a lean spike can happen before your readout box can even send the signal to your eyes.
The doubt motor leaned out as he stated afr's were always in the 10's..
Pre ignition / and/ or detonation is very easy to do with pump gas.
And ultimately that was the reason this motor went..
It needs a more conserative tuneup and/or a different fuel.

I think it's the opposite.. I'm willing to bet those seals come out looking like banana's..

i suppose we will just have to wait and see what happened. i just figured at that level it would have twisted the motor apart if it wasn't pinned.

Ok here we go.. Tore the motor apart today and i cant explain anything..
Lets start with the info..
motor popped on the dyno.. i drove it home. Next day i drove it for at least 50+ miles. Drove it a few days inbetween before i took the motor out on monday. Car fired up a little harder than normal, but drove fine. The video above is of the day right before i took the motor out..
NOW.. Lets talk miracles.. Ok so every last corner seal is broken into 3-5 pieces. All the side seals were intact and all the ALS seals were intact.. Well on the rear rotor when we took it out there was a chunk missing from the corner of the rotor.. HMMMMMM..
Wait for it..
One or two of the seals look slightly bent to the naked eye. Maybe i could be blind..
Wait for it..
Front rotor dented but seals intact, all corners busted..
And the verdict...
NOT A SCRATCH ON THE SIDE HOUSINGS AND NOT AS MUCH AS A SCRATCH ON THE ROTOR HOUSING.......
WHAT THE FART..

if you went from 100 octane to 93 and 50/50 meth that was a bad choice to lol... your taking a fuel that detonates way more than 100 octane does and fed it way too much meth. Put the nozzle near the elbow with 100% meth. your upping your octane a little keeping it cool as well. and 25lbs is not something you should even consider at 93.
my single turbo car is tuned with 93 + aquamist 100% meth 1 nozzle (biggest one) in the spring it will be on race gas tune which will then have the boost simply turned down on the street and no meth.
If you have any meth questions ive been through it all... let me know

looks like the engine did twist some due to the contact witness marks on the rotors. but yeah... that is just simply too much for the pump gas unless you switch strictly to water and add more of it.
so did the seals warp or no? i see irregular wear patterns but that could be from the housings being worn.

Used housings and the tips of the seals were worn irregular. All seals were intact except maybe 2. What's funny is the slot that had the chunk missing had a perfectly straight seal. I have close up pics of the housings but it takes time for me to load them. My phone takes the pics in 8mb shots and the photo size is to large to upload from my phone, which I do all my forum browsing on. So I have to import them to my ipad, resize them, then post them. Dammit. lol.
