I just saw this one being towed in to the shop a few days ago. And he was taking about the Renesis shaft that bent. Now if it's the same car I don't know. If it is the owner waited a long time to get it into the shop. But hey what do I know? Obviously nothing.

Hey don't you have a Turbo install to finish Dave?

 

Oh look! My popcorn is done!

 

Still....its a combination of TQ and RPM that breaks/bends E-shafts not just a hp level. Rew Engines make considerably more tq than renesis engines of the same horsepower because the Reni holds tq higher and therefore generates more hp. A typical 13b with 550whp will have like 440-450wtq...A reni with the same HP can do it with like 380-390 but holding it longer.

I am not saying the Renesis E-shaft is not weaker than the REW..it obviously has to be since its lighter and of the same material, I am just talking about what I have seen in person done with a full Renesis engine not just the internals from one.

I'd say it would take north of 650whp and 9k+rpm to break a renesis e-shaft due to it being weak....and this is based on seeing one at north of 600whp and past 9k in a race car in PR running on methanol...there is no certain proof that this particular one broke just because it was from a Renesis. I've seen people snap the 13b ones at different hp levels...

Also, did he use RX-8 rotors also? Counterweights? if its not exactly the same as its in a Renesis it would introduce variables that make it hard to pinpoint the reason it broke/bent.

Anyone else want to elaborate?

Suay! Im so glad your car is coming together :D I should stop by OJ Imports to check it out. That thing was beast when it was out the shop on cruise night ;-)

 

I never said you knew nothing, stop getting butt hurt old man!

He was not using RX-8/Renesis rotors, as far as I know those are not compatible with FD housings and plates due to apex seal height and side seals. The only Renesis part he was using was the e-shaft which was found to be out of spec....I'm not claiming anything, hell I didn't even bring this subject up

 

Oh I see...now I get it.

I apologize if it seemed as though I was talking specifically to you chicken...I wasnt, you were just the one that pointed out the link.

This actually proves my argument. The Normal 13b has heavier Rotors etc...these put more strain on the Renesis shaft. I will say that the Renesis rotors do work in older engine, I have seen it done....how long they last due to the shorter apex seal height contantly running over the exposed exhaust port? I don't know but I am sure it has to have an effect of some sort at high RPM.

Best regards,

Chris

 

all good stuff guys - good reading but it's about time we all had a hug

 

Dave take a chill pill. Can't you tell sarcasm when you hear it.
If I'd have known about the thread on RCC this wouldn't have gone the way it did.
So stop getting butt hurt. Unless you like it.

 

I'm with Brettus. Good reading, and hugs all round.....

 

I with CAli style, too. Its just that reading what people typed can be read wrong. For example when chris stated "I apologize if it seemed as though I was talking specifically to you chicken...I wasnt, you were just the one that pointed out the link. He actually sounds hes calling him "CHICKEN" as in back to the future "chicken". I kid I kid. Any who back to the subject. Chris will you bringing out that intake manifold on your build, for sale?????

Sway

 

Thats what I hate about the internet sometimes... without tone its really hard to tell sometimes what people are really saying. Sarcasm, irony, and such don't carry over with written words well. Good thread though regardless.

 

Do you sell engines that have these new apex seals with pins?

Something tells me I will need a rebuild in the next 12 months.

 

you can send him your motor or you can buy one from him.

added the icon, looked cool

 

^^^lmao
icon looks cool


sway, i cant wait for your car to be back on the road again!
you and bobby are making me want an rx8


hoping?
or helping?

 

so at what hp do the plates start lifting off from each other? The studs have to fail (overstrech) somwhere around the 650HP range dont they?

 

looking good Suay

 

This is an amazing thread.....it's taking time, and will take more, but it's clear that the Renesis has the potential to make some sick power. Even if at this point the bolt-on turbo kits available have maxed out at around 400ish whp (the esmeril kit), a few different engine internals and we're seeing 600hp+.....that's awesome. (In my opinion if you're going for crazy high power you should be inspecting/rebuilding the engine first anyway, so once more data is available we'll start to know the limits of what the stock block can do and at what point seals and such need to be changed out). But the power potential is definitely there....

Keep up the great work guys...

 

how much for a rebuild? and if i were to buy a motor from you how much?

Thank you

 

he dose really good work, i just got fc and im gona do 3 rotor swap. and rebuilt my engien and port it out with Esmeril Racing and pin it...

 

check the website or call them for quotes and stuff like that..

dont forget you need porting with flow bench test.

 

check the site.......

 

We still giving out hugs? I want one XD

 

 

sorry if the video sound funny my speaker bust i think
but this way it sound when his car was done
