Engine rebuild:esmeril, ported, dowl pinned.
 

As stated above. This is a must see for those who are going FI. The build you see is the setup that most of us need! It will hold up and should not "crack under pressure"! DO NOT FORGET THE VIDEO!

The above two do not allow much room, so the side seals wont fall in. The housing were put on a flow bench with very good results! starting point at 67 CFM (cubic feet per minute). AFter they were at 89 CFM.

Hola!

SEE THIS VIDEO!!!!!

This thread is full of WIN! Thank you for sharing this! :)

Porting and Dowels aside. Can this rebuild be done with standard tools? Or does it require a monster press and other machine shop specialty tools?

WOW - that is a lot of Dowels . I thought Chris only did 2 ?

Which ports did you flow test? Is that for the intake and exhaust? 22CFM on each?

It can't be- that would be scary

From what I did with my friend with the shop. We did not need special tool. Knowledge, patience, and socket wrench. This build was not made by esmeril, only the apex seals. Any questions should be refred to Omar from Oj imports.

:dunno: Never mind then. :scratchhe

In other words do the work your self, easy E1 your name says it all. READ!!!!! Things in life are not put on a silver platter. As for the flow test it was done for the intake and exhaust. WE all know it doesn't just take a socket wrench. Just got word on the flow bench. It's a percentage flow rate increase. It pretty complicated to explain. 67-89% was the cfm. The machine is called superflow sf-600. (you tube it)

I think he is referring to the exhaust port which is regarded by many as "un-portable" but we have been "massaging" it with great success for a while now. Omar's (OJ Imports) test are proof of this...its not all just about making it bigger, smoother also works :)


Suay, glad you got it together and that the porting worked (kinda hard to explain over the phone but Omar seemed very knowledgeable which made it easier)...kudos to both Omar and you.

Can't wait to see some numbers. :)

Chris

boricua donde estabas? gracias por todo!


addendum: It took extensive time to do the job!

I asked a simple question. And you come back with a response like this? Your the boy that's suppose to have the answers to this question. Where am I suppose to search? Your information laden post?
All I asked was whether you flow tested the intake or exhaust or both. You were very vague in your comments with the little bit of information you supplied.

And what is this suppose to mean? "67-89% was the cfm" 67-89% of what cfm? Is this an increase over stock? If it is I'm amazed by looking at the barely touched intake ports.

You post a thread like this and people are gonna ask questions. I hope your prepared to answer them. If you want to keep it all a secret then don't put it out for the public to view. And if you do please put up enough information to substantiate the post.

And suay I've been porting Rotaries since 1979. I think I might have a little knowledge in this field. I'll stop asking questions now because I'm getting nowhere.


Thank you Chris.
The exhaust ports can be ported. I've done it. But not as far on the trialing side as this. My main concern is loosing some of the combustion cycle now that the port opens earlier also.

The port does open a little earlier. This doesn't help the bottom end (<2k rpm) but it greatly helps evacuate gasses at high rpm...specially with a turbo. It also has the side effect of spooling the turbo faster as well which is a good thing.

We don't have much exhaust duration compared to a REW engine...this helps with that.

Chris

p.s.I am sure Suay didn't mean anything by his post. I know you are knowledgeable and your questions are legitimate. He probably thought you might be another newbie asking questions without searching, I know that is not the case.

those apex seals have esmeril racing on them? that is pimp.. what is the difference in those seals and stock ones?

Alright, I get the upgraded seals and the porting (despite whatever controversy) but what is the point of pinning a Renesis? What kind of boost are you planning on running? I've never heard of any piece of the engine failing before the apex seals. I'm honestly curious what the benefit will be.

uhhh...mmmm

That is because they are Esmeril Racing Apex Seals.

The only thing they have in common with the OEM ones is the shape ;).

There is a thread on them in this section, search for it :)


Chris

You are right...the seals are the first thing to go always...but if you upgrade to better seals (ours ;)) the next thing to go is the front plate which cracks in the area around the top front dowel pin. It is not immediate...just with apex seals you add at least 100-150whp to the range the engine can take easily but if you already have it open and are porting it why not pin it and add another hundred whp of capability? This has been documented quite a bit already.

You can even cause failure in this area from pure torque if running really high boost but normally it happens from detonation.

Simple, weakest link...first are the apex seals which are addressed with our set and next is the pinning to prevent cracking of the plates...now you have a 5-600whp capable Renesis.

We reached 414 on a non pinned, non-apex sealed engine but the margin for error is small. the apex seals widen that margin by a mile...the dowel pinning further widens that.

Chris

wow nice,

I have first hand experience of this - not nice .

Cool info, not sure why you are being so secretive though.

Nice! I'm certainly looking at the various options for tricking out a Renesis motor if I have an engine failure and need to replace it. No point in swapping in a basic reman, because if the motor is already out I plan to put in some goodies too. I didn't realize the Esmeril seals were resilient enough to bring the survivability of the front plate into question, thats actually very good.

i'm sorry for the lash "easy" i honestly thought you were a newbie, lol! No honestly i am just know what my friend and owner of oj imports tells me. When i write 67 CFM rated in %, I mean it was 67 stock and after the port it jumped up to 89% CFM. I know very little and have read my ass off since I had the car in late 03'., but as we all know this motor is it's own entity. I can tell you this, what you see in front is one of the first of its kind and I am glad to share the info with you guys the best to my knowledge. Questions refering to the port should be refered to OJ imports as stated above. YOu can send your motor and will not be disappointed. Once again sorry for the lash. I just can't tell reactions from typing at times.

ps I feel good about this setup and will have numbers soon.

SWAY (I spell it suay since someone had chosen that name already.)

Thanks again

im helping to do this setup soon:)

Apology accepted.

You will have another hurdle when you crest 500. Easy has already seen what happens. ;)

drivetrain?
