Someone correct me if I am wrong. I was just under the assumption that you could slowly bend that rod (or quickly) form being just past MBT and causing too much stress.
You see other users on E85 pushing 400+WHP on their car and they are still running. I would love to see a comparison of some cars that are and aren't running to see the ignition vs fuel at certain loads.
From my point of view for all i know cf6mech's new motor may just be stronger (or more flexible depending on how you look at it) than the previous one due to the bearing setup and more resistant to the shock of being close to MBT on E85. |
Yeah, very possibly could have been what you state or oil like cf6mech thinks. I'm glad we can rule out detonation since nobody really learns anything there except for bad tune and everybody already knows that can destroy any engine no matter how robust. The whole cylinder pressure without det is very interesting topic though (especially with how E85 allows the tune to be so much more aggressive either NA or FI) as I had not thought of that until it was posted up, I just assumed it was det or oil.
If you want to tune it yourself, get help from the community, and also a little help from reputable tuners a solution like this probably would be the way to go:
