This is educational, entertaining, and calming all at the same time. I'm learning so much and I'm also aroused so much lol

Rob if you were a dog you'd be a pit bull. Lovable and loyal to a fault. Tenacious, and you never give up. When my FC turbo gave up catastrophically on startup back in '96 I couldn't afford to fix her and didn't understand how or why it happened. So I had to let her go. Still breaks my heart to think about that car. I watch these and it takes me back to hear your car scream, although my 13b never quite sounded like the monster you're building 😳🤣 Keep up the great work sir

So much work for a rotor Wankel which was a failure allover the world. This motor has no future if not only for stubborn freaks. Even Mazda gave it definitively up.

Rob, burning a little oil does not hurt in a valve 4 stroke, helps keep the intake valves lubricated, through crankcase breathing.

🚨🚨🚨ROB🚨🚨🚨 SERIOUS QUESTION...Have you checked the fazing on that eccentric shaft, as far as TDC on each, I bet you its out..! Its the way its manufactured, this is what will kill this engine..!
Anthony N

The more I watch, the more I have to comment, the eccentric shift does not push Rob.... the rotors push the shaft, fuck Rob, get with it..!

Nobody's ever run a motor like this before...? WTF..!!! Rob, you are far from the only person to have a 4 Rotor, and there are plenty that have been driven way harder..! Your engine isn't suffering ecause of the 4 link, your driveline is whats coping the pounding..!

Yeah 1400 but the car only went over a 100mph once when facing the hoonicorn which had a ton a problems with fenders an bumpers flying off the car in every pass. Its more of a show car not a performance car to compete with. And the owner needs driving lessons ASAP.

I would love to this awd rx7 race against ken blocks hoonicorn 💪💪💪 #japanesemuscle

Nice, ball bearings are great for oil loss situations. Sure, if you have oil and oil pressure, journal bearings are near frictionless, but have your oil pump crap the bed and things are not good.

Can you please address the EPA trying to kill our car culture and community and some of our lives if you do not know the EPA is trying to ban everything car related including tuning, boost and many other things. We are under attack we need to address this now before it becomes too late. We can counter this if we gain Support for the RPM act the link to SEMA's page on it is listed below.

Build a 4 rotor drag car and make it work I guarantee you your channel will blow up big. Plus that's really exciting unlike whatever that is you got going on because you're just spending mom and dad's money on BS. You went in that thing because that shaft is very expensive.

Us Puertoricans the kings of the rotary engine who you don't like to acknowledge very much, we make upwards of 1,600hp with a 13b. But you build a nice car for what it is.

I just stopped by to say that Ken Block currently has (arguably) one of the very best performance cars that's ever existed on this planet and a team of tuners that knows it thoroughly so you almost had no chance of truly beating him..now that I've gotten that out let me say what I actually wanted to say which is that no one with an opinion that matters gives a FUQ because your 4-R car IS (not arguably) the baddest car currently circulating the internet and I mean, does anything else really matter..that's rhetorical but I'll assist with a "NO"

Rob, I have a question that has been on my mind for a while watching your videos. It always seems like your gear ratio is too high for burnouts and hole shot launches. I’m I way off on my perception? Does anyone else agree with my observations? Thanks, Gas Pump Rob here in Southern California

@Jake O'Shaughnessy Maybe so or maybe it’s because he is running an ultra lightweight flywheel?

Yo Rob, Its been months now and I still don't have my shirt... I've tried emailing you several times and message goes undelivered. WTF man? I'm not a wealthy guy at all but wanted to contribute to the RX7 and now I just feel ripped off. You probably won't even see this and again my message will fall on deaf ears, I'm still $50 down and no shirt! :( FML. Has anybody else bought a shirt and not yet received? (Bought in October)
