Dyno Day!...Thrills and Chills...
Well folks, the results are in, and the setup performed very well. We saw a bit of extra flow from the addition of the billet wheel. Our last run was at 24psi, and it LAID IT DOWN! In the process, the rear rotor let go. As the official results of the failure are yet to be discovered, my tuner is pretty confident it is a warped apex seal. As the engine is using OEM Mazda 2 piece seals, it is rare for them to warp. Whatever the real damage is, it will be known when we tear it down. Whether the seal cracked or warped, we will see. I am confident that my turbo didn't take any damage. It will definitely be inspected though.
AFR's were solid and it never ran lean. EGT's were also solid as each rotor was within 10 degrees F of each other.
My plans are obviously to rebuild the engine better than before. It will be studded and running a performance apex seal. I want to really set it up this time around.
As I pushed the envelope of my engine, I knew there were risks. Those risks caught up with me. As more time and money is ahead of me, the only real consolation I have is that I made big power for the first time, and I will be BACK!

My tuner said he could feel it let go up top at the very end of the pull.
I have been racking my brain trying to think of what could have caused it. Once the engine is apart, we will know more. I just want to make sure it wasn't something in the setup. I don't think it was, as AFR's and EGT's were solid.... but I want to absolutely make sure. My hopes are that it was an engine build issue.
540whp is a lot of hooche. I'm still using the OEM lower manifold. I considered it being an issue, but my EGT's were within 10 degrees of each other under full boost. The same could be said for my injectors and pump. If I was running out of fuel, the AFR's would have jumped. They were solid, and even dipped into the 10's one run.
Same for my WI system. I'm going to test it, but if I would have drastically lost meth, my AFR's would have leaned out.
We don't want history repeating itself with my new wicked engine!
