Yeah, I may have lucked out losing access to ethanol... The mirror attachment is not very good quality, unfortunately. But here is composite of the end of the camera and a pic in the motor. When I was moving it around and looking at it live the inside of the housing and side plates looked like a mirror...

What kind of premix were you using and how much? FWIW I ran E50 for a solid 3 months with Red Line alcohol premix 4oz per tank, December 2015 to March 2016 (easily a couple thousand miles) and my internals showed no sign of wear like that... But stock apex and corner seals. Not saying I disagree with the findings at all, just adding to the narrative. I think you are likely correct, it might just be the mix of ethanol and softer seals. Remove one or the other and no worries :dunno:

Man this blows :( I feel for ya... What are your plans at this point?
|
First thought was to push car off a cliff ....
Once I got over the initial dissappointment I decided to get it going again. Have all the parts assembled for another engine . Will get it dowelled and have the rotors cut for deeper seals . Still thinking about what fuel /apex seal / power level I want to run. |
Get back on that horse my friend! :) may I dare say try again without ethanol? Switch back to WI? And settle for mid 300's which seem to be pretty safe with the experience we've gained... :icon_tup:

Not sure if I'm clear on your intent.
Are you sending only the end ports to the turbo and dedicating the siamese port for wastegate flow only?

My rotors were cut for full depth rx7 13b apex seals ............... https://cimg5.ibsrv.net/gimg/www.rx8...ed7bb81fc5.jpg for some reason my post are not going in. send us an email and we can help you figure out what happened. thank you |
Where's the Unlike button when you need it?

Those pics remind me of every Big Foot sighting pic ever, :lol:
Glad to see you're back in the saddle Brett. |

Glad to see you're back in the saddle Brett. I tried, was the best I could do. Who knows, maybe mine is disintegrating inside as well. Time will tell and either way I accept it... |

And just like Bigfoot you still haven't seen anything north of 12psi :p:
I tried, was the best I could do. Who knows, maybe mine is disintegrating inside as well. Time will tell and either way I accept it... And I don't plan to either, :lol: I am living vicariously thru you guys while putting around at 10psi. |
How's it going Brettus?
|
Things are coming together slowly .............. no word yet on a finish date .
I'm leaning heavily towards using stock apex seals and reducing ethanol to about 25-30% |
Pullin' for ya man! Any thoughts on seals and whatnot for this round?

RPM seems to be the issue i'm having at the 400 power level . Need to restrict rpm to where power peaks then either drop the rev limit or drop off boost above that point. All the bad stuff I've seen has been after peak rpm .... no sign of any issues before that with Ethanol. |
Stock rx7 or rx8 apex seals?
Also, same here regarding RPM and problems. Both times I blew a motor was high in the RPM. I don't have any logs but I believe somewhere in the 6500-7500 realm... |

Damn, I'm glad I never went for the high ethanol blends. Are the Rx7 guys having this kind of problem, or is there more to it?
