Yes E85 fuel and yes 17psi peak - as for not checking the catch can it was checked and emptied between EVERY run - essential with the amount of unexpected blowby in a fresh motor build - ~1l of oil in a single longer session, GT auto installed 2 catch cans to have enough volume to stop the catch can leaking, when I asked about the large amount they said that is how rotaries of this level work, the oil fire however was caused by a incorrect thread for the oil feed into the turbo and coming loose
