I think he means the exhaust...

 

likely either the front and/or center iron plate, but hard to say

 

this seems more likely actually, when the engine mounting snapped it took the housing/iron with it?

 

more likely ..... it had a massive ping and cracked the iron and broke the mount at the same time .

 

oh, i got the impression from the post that the motor mount failed first, that must have been one hell of a ping

 

Exactly what I think as well. The comments that followed on that post were also gold.

 

Took a long time to get the info out of him.

 

Also hello, its been a while.

 

too much boost or too much timing ? so the engine ping'd, or just snapped the mount and launched the engine breaking the front cover?

 

Something like that, dude never admits to his failures. His engines are made of pure magic. I am sure the apex seals enjoyed the tumble.

 

I know a few people like this. if you can't admit defeat then you can't proceed on a better course of action. it's counterproductive.

I like the magic engine comment

 

Sounds like too little engine mount to me....

 

Nothing indicates that the engine blew. With E85 or race gas it's not too much boost. It might be too high AIT without the proper IC or airflow. Have seen an REW make mid-4xx whp with the same turbo/boost on C16 race fuel.

 

You would be surprised how violent it can get if things go badly wrong .

 

You of all people should no better then to compare an REW to a Renesis...

 

i've seen a few pispot engines pop rods and blast through pistons from a ping but didn't think it could be violent enough on a dorito to crack the housing/iron.

 

I wasn't making a direct comparison. My estimate for the Renesis was lower than the REW as documented in the thread. Just the same, the end goal here is not using pump gas. Running that dyno number should be entirely possible if everything is done properly.

All the dodo birds squawking their big beaks and flapping their little wings on Facepalmbook are bad enough. We don't need it here too.

 

Based on the last comment from Lester, I still don't know if it was the front cover, front iron, or front housing,

 

Many things should be possible, and many look great on paper. I have yet to see any renesis engine taking that much boost and running long enough to talk about it.

 

No ..... very confusing commentary there . The OP needs to wade in here and give us the full low down .

 

Done been done. Not everything revolves around this forum. Quite the opposite actually.

I would still choose an REW conversion though.


.

 

I've never seen a renesis hitting 20 PSI on any turbo lasting longer than 10k miles.

Anyways, yes an REW is the ideal choice.

 

Pretty sure my current setup would last at 20psi no problem. Once i modify it for faster spool ...probably not .

 

Yes, its said quite often. But I have yet to see it in practice.

 

It's a shame I'm not going to be able to prove anything on this . But what i can say is 20psi was a breeze to reach (tuning wise) and there were no issues . Timing needed to be conservative and AFRs did need to be kept in the 10s however.
