Huge thanks to Logan at Defined Autoworks for balancing the rotating assembly and filming the process. Check out his IRpost channel for less clickbait more technical content like this.
It’s awesome to know my engine is balanced to handled 11k but I highly doubt it’ll ever go that high as it’s side ported and will face diminishing returns on power.

Yea uh, getting the rotary to work with the DCT will be interesting to say the least not to mention a 4-rotor is much longer than the LT-2 engine so unless you are planning extensive chassis mods to the C8 i think you're blowing smoke, keep dreaming and maybe one day someone will create a standalone TCU for the DCT then you just have the problem of shoe-horning the 4-rotor into the engine bay but I honestly don't think the 4 rotor C8 project will ever come to fruition.

I watched this whole boring ass video from end to end and loved every minute of it, was awesome knowledge in fact..Dahm, I drive an '04 Cooper S-JCW yet you're making me a rotary nerd all the sudden, I think I like them because ive had a couple of banshees and rotaries remind me of that same uniqueness

was it Norton that won the TTRace on rotor engine every year..till they said the engine as a cheat mod' giving an unfare was smaller and so much lighter than the other engines but still gave out the same amount of power to the back wheel.. left them for dead.. rip

Logan is not only a beast in the rotary world, he is also a super nice guy. Defined is about 30 minutes from me. Really happy to see you working with him!

Logan is a freaking genius. I remember when he started posting on RX7club about his naturally aspirated 3-rotor project. He left no stone unturned from the very start and has never stopped. It never ceases to amaze me when I see the latest iteration of his car. And to his well-deserved credit, he's been sharing all of his knowledge from the very start.

But the rotors rotate with 1/3 of the shaft rotation and slide on the eccentric so that with a fixed rotor balancing is not a real state, right?

A 4-rotor engine, balanced within half a gram and revs to 11,000rpm, built by Defined Autoworks, going in a C8 Corvette with a double clutch transmission. Stop it Rob, you're scaring the Cannonball Runners...:D If you tried a Cannonball run, you might break the 24 hour mark. Just like Mazda dominated LeMans in 1991.

If hes got it on the balancer, why not get it 0.0? I understand its within spec, but why not get it perfect. Another 20 min maybe. I'm not bashing, or down talking as he obviously knows what hes doing, I'm just saying. I know Ron at cedar machine would get it 0.0.

Because you shouldn't is the short answer. Below .2 to .5g the machine generates ghost noise and it cant be trusted anymore. It becomes a phantom weight and will move all over the place. Chasing it down will take hours and just waste your time. Nobody knows the exact oil weight inside the rotor at every rpm point so in a running engine that effort would have no reward at all.

Is ther a reason y people don't take as much weigh as possible out of each Rota and crank and every other engine apart s that matter? I would of fort it would help a lot in how fast you can rev and less engine wher and that

This guy is a really good machinist and obviously a bad ass rotary guy. I laughed when he said it's hard to make a video like this engaging. It might just be me but it's always cool to watch a machinist work who's good at their craft.

I wouldn’t replace that wonderful GM V8 with a rotary engine if I were you! Rotary engines have their own problems as you know! It seems reckless to get that V8 out of that car and replace it with a P.O.S. Rotary!!

cncaliguy09 پیش 5 ماه
You could've gotten the rotors CNC lightened so they rev up even faster and then balanced them. Might even reach a higher RPM with lighter rotors if 11K aint nuff stuff.

Will oil get in those drilled regions on the sides of the rotors behind the apex seals at all? Surely if the end up with oil trapped in them it cancels out the weight removed?
Paul Copeland
