what Team said + remember that the side seals are now closer to the actual combustion--which also carries some heat, the rotors have a thinner combustion face which also means more heat to the surrounding areas. Heat heat Heat.
I do wonder if anyone has actually measured the heat difference at the side seal between the two engines?

Once I have the motor apart I "hope" to have a better idea of why the two side seals let loose. Whether it be from the porting (seal catching an edge) or from heat, just hoping it's conclusive evidence, if it's not, I'll have to decide what to do next...

correct me if I am wrong but if a side seal catches a port edge dont you immediatly have problems? But if the side seal has slowly deterioated due to heat issues then the problems are not as severe and slowly become appararent?
I am learning too.
I am asking around about a zero clearance side seal build for the us. People are "thinking" about it. It may work, but it may not. IDK.
One thing I have wondered about---we dont have room to run a double spring set up in the side seals due to lack of room in the groove. Has anyone considered or done any milling of the groove to MAKE room for a double spring?

You may be right, now that I think about it your idea does make sense.
I'll hopefully get a better idea very soon...

DO NOT zero gap the side seals, been there done that, it doesn't work.
Motor was practically impossible to fire up, and then when it did it didn't run for long.
Pulled the motor, gapped the seals to .004" and it fired right up every time and ran until I shut it off.
I used to run double springs in my FD motors, no idea what it would cost or if it's worth milling our rotors for double side seal springs yet.

You forget that OD speaks in obtuse terms. So much so that he doesn't know how to explain himself properly for anyone else to understand.

Thumbs up

Thanks for posting these. Do you think that removing exhaust sleeves is necessary for forced induction?

There is definitely no conclusive evidence that removal of the exhaust sleeves on a FI Renesis motor is beneficial let alone "necessary"...at least not yet.
There are so many variables involved (high boost vs. low boost, fuel type, engine mods, application, etc.) that one general/universal answer is simply just not possible/realistic.

I can tell you this though, it does NOT have any adverse effects on coolant temps...again, certain variables do apply...

what about the dead air space caused by the air injection system between the sleeves and the irons?
Is that something that could be eliminated?

Nothing really to report other than the fact that the motor is finally almost out, I'll post a detailed tear down as soon as I can.

Teardown

Damage to rotor from stray side seal piece that broke off after catching an edge on intake port and dragged through the motor, more pics to come:

/\ which side of the rotor - side or centre ? Any sign of overheating around ports where the sleeves were removed ?

Any updates on the most promising Renesis? How much has your wallet suffered so far?
