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?

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

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

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?????

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.

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...
