u want a good mirror smooth finish? use a cloth type and buff it. don't finish with sandpaper, your surface will usually always mimic the material you use it against.

I used to port & polish intake manifolds. Good on him for wearing safety glasses, but wear a respirator too or at least a dusk mask man, especially with the finer grinds!!

Who would have ever thought that my vespa had something in common with an RX-7 other than burning oil! XD It uses kinda the same principle to regulate airflow

At idle and low throttle, the throttle body keeps the butterflies for the secondaries closed. Air is not being fed to them.

Where's the PPE? I know face masks are a little scarce currently but at the very least a shop vac going to make sure you don't breathe in metal when porting.

Hey Rob, I’ve subscribed for years but I’ve stopped getting your videos in my sub box. I’m super annoyed. I look forward to your videos, but it’s hard to keep up when they are seemingly hidden from me. I don’t know if you have a IRpost Rep you can speak with, but this is disheartening. Cheers on the great content, but just wanted to flag this issue for me. I’m on IRpost hours a day for car content and always check my Sub feed.

The primary injector starts @ 3000 rpm on my 13 b Turbo. Before that it gets its fuel- air - mixture from the secondary injectors higher in the manifold only. I once mixed up 2 injectors ( white - black stripe with yellow black stipe ) . Poor ideling but no problem on higher revs ...

Regarding the secondary port flow, the stock throttle bodies do have staged butterfly actuation and secondary cutoff flaps (that are often deleted) so that the secondaries do not flow air at lower rpms/throttle settings. I imagine this to boost flow through the smaller primaries (to help with lowend torque) and to reduce pumping losses. The 6-port NA engines take this a step further with the Aux port actuators and variable manifold actuator on the S5, to say nothing of the Renesis' intake.

@Rob Dahm I'm the exact opposite, I never got too much into extreme rotary builds. Rather, I built my '84 widebody up utilizing factory engine components pushed to their limits (reasonably). I took the best 1st gen award at SS8 partly because I still had a CA approved, smog legal S5 TII engine pushing 400hp, still sneaking by the visual, functional and sniff tests.

Reminds me of visiting my old rotary specialists workshop. While hand grinding/shaping ports he would periodically test the flow by placing the iron into a water trough and pumping water through it. Such a black art.

@Antti Brax I don't think he showed them out of spite. I just think he didn't see a point in blurring out of respect if he no longer has respect for the man professionally.

More likely because what they did here was no different so there was no point in keeping secrets. It's a bit nasty to go assuming that other people do things in spite.

Gary! پیش 6 ماه
It's not a dremel, it's a die grinder... Also cnc is better for high volume as it can be quicker and more repeatable, but itll be a copy of a hand ported head most of the time, and most still need finishing by hand even after cnc porting.

Hmmm..I don't know Rob..Has this "Port Design" been tested on a Flow Bench??..That rise in the Port was put there to help control the "Pulses" that flow back and forth during the at idle to full throttle operation of the engine..Have you ever checked this with Jim Downing??...He and his Shop are the "Go Too" guys on Rotary's..In my experience with "porting" (don't follow my bad example).."wide open" ports can really screw up the performance characteristic's of an engine..You usually lose Top End or Bottom End with the performance curve making the engine not "streetable" (super high idle needed or going "Fat"..)...I love your channel and follow your "build dreams" as often as you post..Maybe you can "tune" this issue "out" with your Computer...When I was a kid (like you) The only time I would "Hog Out" a profile like that was "WOT" ..Land Speed for instance...Timing that "Pulse" so that there is a Vaccum on both the Intake and Exhaust as the engine "Blows and Sucks" crams more AFM on Intake and Scavenge's on Exhaust..."Port Matching" is a budget performance gain but "Hogging" or messing with "ramp" can bite you in the butt..All my BEST WISHES!!..and I hope it's a Screaming Demon!!🇺🇸

Porting a rotary engine basically where do you want to make the power at and at what power band you are looking to make the most power you can't just go in Port a rotary engine any which way you want every port is different and every port is meant for a different RPM please explain this to people because people are going to go open up their Motors and just start putting the hell out of them and not know what they're really doing
