You might have me on that one. It could be run off of the airpump.

Yes it would affect low speed power. It would increase it. The turbo makes up for the top end. It would be a nice braod power curve.

If you blow up an engine at only 5 psi, it is really quite simple, it wasn't tuned. Period. I don't buy into the it was the side seals crap. They are sheltered around the side of the rotor. They may cross over the exhaust ports but the exhaust gasses do not directly cross the seals. Look at a rotor or a picture of one sometime to see what I mean. The side seals are much thicker and stronger than the previous seals as well. I find it interesting yet strangely disturbing that one shop could blow up more than one engine. If it wasn't one shop, they do know the people who have done it. Since no one here knows of anyone who has, it is easy to see that they are affiliated in some way. If I blew up 8 motors, I'd find a new line of work. Don't be afraid to tells us who they are. You'll do us a favor by letting us know who to avoid. I won't use them anyways so no harm done here.

Just some food for thought. If someone were developing a turbo kit and knew they had competition, they could very easily claim that the engines blow up with forced induction. That way they would discredit their competitors systems. Then when theirs hits the market they can claim to be the ones who have solved the problem. Not everyone falls for it but some do. We see it here on this forum from time to time. Some people still claim the engine can't be boosted. It can.

I concur. A broken side seal, I believe, has nothing to do with the actual combustion process. From the looks of it, the side seal might be the last one to be compromised. I hope someone will be able to answer this question:

see i should have said my piece first and then had rotarygod back me up. side seals breaking seems to me like it would be more of a oil injection problem than a boost problem. also another thought. how did they get 8 motors to work on? did they buy in bulk? or did they break the same on over and over. what's the going price for a renesis? somewhere close to $6,000 right?

shelleys_man_06

Don't feel bad Zoom44. You did make a good point .

Is it possible to buy engines in the bulk? Seems kind of like a Sam's Club deal . I hope whoever broke eight engines didn't use the same one over and over. IMO, if it breaks once, there's no point in re-trying. I would imagine that a 13B-MSP new would cost $6,000.

zoom44

but i think if a "good" rotary shop( think Atkins Rotary) toasted some seals while tuning a new FI component they would pop it open fix what broke and put it back together. they would also know exactly WHY they toasted those seals. so they would not repeat that mistake. if for some reason those seals broke again they would be replaced with much stonger ones. there is no reason for someone to burn thru 8.

Guys,

I am not sure if you are aware that a turbo has been sucessfully added to the renesis engine. They claim increased power with low boost. Try the following link for more information. https://www.rx8club.com/australia-new-zealand-forum-37/rotor-master-turbo-30526/

I understand the system is for sale.

thanks for the link. i should pay more attention to the aussie forum since they are well know for their rotary madness. i have posted there for more info.

This is what I get for avoiding the Australian RX-8 Forum .

In rex'es side seal only usually break if you clearence them bad, or the rotor hits the side housing, or super bad detonation or soemthing else catastrophic. It is possible though that the side exhaust ports are stressing them much more, or maybe the new keystone side seals are weaker? or maybe it was a fluke....

shelleys_man_06

What are the keystone seals made out of?

Beer bottlecaps!

I just tried calling you! Check your messages!

Sorry about that. I was at work.
