^ WHAt fred said ^ i tried to make that post short and sweet having little time. i actually ended up wasting more time editing trying to find the right word to use. at least it got the response from RG that i was hoping for

guitarjunkie28

the leading edge of the corner/side seal is supported over the duration of the travel--all except for the very closing edge of the exhaust port. the one i've got apart right now has absolutely NO damage whatsoever. the side seals weren't rounded at the corner-like you'd expect from that kind of damage, the closing edges of all the ports were fine.

as far as the clearances go, i'll just have to take some pics so you guys understand how the new style side seals meet up with the corner seals.

Mazda also claims that this shouldn't be a problem, as they beefed up the side seals and went to the keystone shape to help protect the edge as it passed unsupported, albeit briefly.

mmmmm pictures. Haha, anyway hows the port job going with Snoochie? Or did you not start it yet? I've been kind of slow lately so I apologize if this is a silly question. Snoochie, will you be there while Guitar rips the engine apart? And if so do you own a digital camera? If you answered yes to both of these questions do you think you could take some pictures for us along the way? You guy are awesome, good luck.

Snoochie

We already ripped alot of it out today. I think we stopped after taking out the upper intake manifold and he's going to finish it off 2marow morning. It only took us like 2 and a half hours to do a whole lot of work (then again I didn't do much but I unscrewed a couple things :D ). It was very fun though askign him a thousand questions and semi helping out.

I do have a digi cam but I forgot it today. Besides, the stuff we did today (just ripping it out) is really basic and anyone on here can rip theres out and take their own pictures. It's when porting time comes that pictures matter and he has a camera as well as i do.

Aoshi Shinomori

That's what I meant, mostly pictures of the actual porting. Thanks for the quick reply and I hope all goes well tomorrow

Snoochie

I won't be there 2marow because I work all day but I'ma go up in a few days hopefully before he ports so we can have some stock pics. Even if I'm not up there he has a camera so it's no worry. We'll keep you all updated we aren't hiding anything.

It's funny but I made the EXACT same comments about side seal support before I saw one that did in fact hit. It can happen.

guitarjunkie28

did the engine i've taken apart get a different set of irons or what? closing edge of the aux. intake port, right? the side/corner on the leading edge of the rotor was totally supported.

i've heard rumors about that, so i checked it extremely closely. but even so, i radiused all the closing edges, it helps flow out.

IcemanVKO

Guitar, please clarify that last post for us rotory challenged morons out here

Did you take out the other engine and fine it was different?

guitarjunkie28

no, not yet.

but the one i have torn down looks like the corner/side seal junction is supported on the closing edge of the intake ports. i got a disposable camera--which takes 10x better pics than my digital, so i'll put my template on the top and snap off some pics. it'll just be a couple weeks before i'll get to post them though.

i WILL admit if i'm wrong-i'm not a prideful person.

IcemanVKO

You know, while you have the engine apart, its a shame not to replace the flywheel.

mysql101

do they need to drop the tranny and take it apart to take apart the engine? The flywheel replacement isn't something they can do in 30 mins.

rotarygod

The side seal isn't an issue on all engines. They typically only hit in forced induction applications. This isn't to say that they will destroy an engine if they do touch though. The one Racing Beat had apart was a blown engine and it did have the mark. It was a pretty deep mark too. However, the engine didn't blow because of the side seal impact.

IcemanVKO

Good point, I guess I didn't think about that.

Its just the flywheel is a relatively cheap part, and adds alot of performance, just pop the tran off and take it somewhere with the new flywheel and have them swap it for you.

G8rboy

RG- is there any meat to the theory that the side seal damage you witnessed at RB was a result of blown apex seal shrapnel getting lodged between the side seal and port?

What????????/ The man has the whole engine apart and he needs someone else to change the flywheel??????????

ranger4277

They don't want to change the flywheel at this stage, the objective is to dyno the engine post porting to see the effect of JUST the porting. If they're undertaking an operation like this, dropping the transmission for a new flywheel won't be a big deal anyway.

**update**

engine is sitting in my driveway . i gotta go make some room for it in the garage (i'm doing 4 motors right now).. it should hopefully be torn down by tonight--tomorrow morning at worst. i'll get the exhaust porting done and welded up tomorrow, then take my time over the weekend for everything else.

it's a lot warmer today then it has been for the last week, so i may try that port mold tactic. so anyone know where i can get the release compound, or would wd40 work?

i shop i talk to said you should see anywere between 40 to 50 hps they done about 4 of them.

zoom44

what shop did you talk to that said they had ported a renesis? or at least where are they?

ranger4277

Yeah.. I would have thought we'd have heard about it by now if somebody else had ported a Renesis.. 40 to 50 would be very nice!

smokinjoeracing ,they will be doing my car as soon as i get my transmission checked my 2 will not go in on high rpms , they only work on rotarys

Well, I just found this thread and have been reading every single page/post so far. I wish I was closer to help out as well and learn some stuff. ALl I can say is that once this has progressed a little more, if at al possible during the holidays (when I have 10 days off) I will be buying a motor lift :D

Hell, my engine warranty is more than half gone already anyways :D

BTW, if you want, I have my ODB scanner (canscan) that I aint using right now since I already pretty much tuned my car to where I want it, so I am willing to loan it out if you need something for the EGT's, as well as everything else the engine reports through the port.

Let me know and I'll gladly post that out. all I want in exchange is RG's home built flowbench setup :D

guitarjunkie28

thanks for the offer, but i've got a scanner. i bought it when i was working in a "real" shop. lately though, all i've done are the rx7's so no scanner is available (or usually necessary) for them.

i'll go ahead and plug it in when we get it back together just to monitor the basics. it does datalog, but the sampling rate is just dismal and unusable for what we'd like to do.

anyone know of a cheap obd2 datalogger that does more than 10 frames/sec?
