How To Bridgeport A Rotary Engine

[@neiljborja]

Nothing inspires confidence like opening the video with a dude using a pair of pliers as a hammer . . . .

[@richs5768]

Could have been a crescent wrench lol.

[@redrhino1911]

I about pissed myself reading this 😂😂

[@Thee_Sinner]

Omg that fast forward shakey cam was hell.

[@MrErikw26]

What kind of effect will this have on the longevity and reliability of the engine? ( all things being equal of course)

[@JoshRex7ven]

any porting will reduce engine life. A bridge is probably the worst due to how close the "bridge" is to the water jacket

[@anl5370]

@@JoshRex7ven will billet bridge port plate solve the problem?

[@MyMIXmedia]

7:52 Uneven clearance between the oring and bridge. Thats to close in my opinion.

[@trash3570]

So when the rotor is spinning the side deal runs across the "bridge" and doesn't fall in to the intake

[@mynameisdarrenc]

please invest in a tripod...

[@DrSlay1313]

Please!

[@KennyatHumble]

I have a tripod, just not on this day lol.

[@Drunken_Hamster]

Questions. What about an Extend port? And why not just cut the port to be as wide as the bridge adds to it? Or rather, why not just cut out that metal in between the slot and the regular port to make a "super port" or something??

[@KennyatHumble]

All your seals would fall into the port. Your corner seal and apex seal rides on that material .

[@Drunken_Hamster]

Rotors Magazine I pretty much figured that out as I watched your other videos, lol. I tend to ask questions a little quickly. My other questions on the other vids still stand, though. So, answer those whenever you can???

[@r.five.3]

3:15, thats how you snap bits

[@jza80king]

He's talking shit on the "other guy's port job" but it was probably him

[@capt.k8577]

ever heard of oil on your drill bits?

[@roachboy97]

Dont need oil on cast

[@monk3yman1997]

its a rotary he is used to having no oil

[@adamwest2130]

@@roachboy97 it doesn't matter if its cast. Oil stops the bit from burning up.

[@roachboy97]

@@adamwest2130 Nah the carbon in the cast will actually lubricate the bit enough

[@LOSTINTOUCH30]

@rotorsmagazine I am researching on what it takes to build a rotary drag car. Can you give me any pointers on where to get car from?

[@KennyatHumble]

Anywhere. Craiglist, RX7 forums, RX7 Facebook groups, depending on your goals, it might be beneficial to start from an NA chassis and find a turbo motor separate.

[@n1cholas.w]

should I Bridgeport my 12a Streetcar? it's stock with a full exhaust and weber 48ida.

[@KennyatHumble]

Depends on what you want for an application. If you want an easily streetable car that gets decent gas mileage, no. If you want a racing application and don't care about MPG (~8-9mpg in my experience) Go for it. Make sure it's done by a skilled builder, otherwise you be eating side seals!

[@n1cholas.w]

could I do it myself with the correct templates and knowledge of tools?

[@ChiefStyn]

Yes

[@cheesmastr5303]

Nick White if you have to ask that, no.

[@galaxy1113]

where u located I have rx7 street port but I want brige port but I'm in n.c I haven't find nobody that deal with that

[@TheLoca215]

Do you still sell your templates

[@frankperez9949]

do you have to do te chafer in the housing right

[@powdere4donuts]

How much does a 13b longblock weigh?

[@KennyatHumble]

~200lbs before turbo depending on which block it is

[@justmeokay8253]

His own custom template made out of a shingle.

[@meca13b]

Is that a flex shaft dremel ?

[@jimlondon1]

HOLD THE FUCKING CAMERA STEADY! GOD DAMN IT.

[@ashleyparry2470]

i thought the bridge would be prone to cracking over the time with heat cycle of the engine ?

[@jerseyrotaries]

That was the ugliest job I've ever seen 🤣🤣

[@MegaDragge]

How to make the seal snap off even more

[@dman1049]

Why would you Bridge port it Vs opening up the entire port and making it larger...?

[@calebfox6038]

If you are talking about cutting out the bridge itself (the part left over in the middle) you will break your side seals because they fall into the gap catch the edge and break off (side seals are the ones that seal the rounded edge of the rotor)

[@elanzobesai6906]

Real close 2 d seal

[@casterdell94]

Please get a tripod. Good video but good lord I’m dizzy

[@MrNightware]

Doesn't that hurt apex seals?

[@KennyatHumble]

Your intake ports barely touch the apex seal. The bigger concern is side seal longevity.

[@MrNightware]

Alright, just thought that seal or metal bar/line on tip of rotor would slowly get eaten up by that port hole you made as it shifts to sides over time. Why else factory shifted intake hole more to middle instead having it from edge. :/ Just curious and bit worried about that.

[@SFFRACING]

I would like a template of your bridge is that a posibility

[@KennyatHumble]

We do not give out our bridgeport template, sorry!

[@ut5av]

Rotors Magazine but would you sell it? I'd buy it!

[@gerhardengelbrecht9679]

nice hammer!! and bridge port not on spec.. doesn't curve correctly with the the flow of the iron.. sorry

[@weepy...]

Bruh keep the camera straight 😭😭

[@alexanderwaphardt8714]

So this will make my car brp brp brp brp???

[@rustymarine929]

Get yourself a hammer and a tripod next time

[@VertigoGTI]

I'm surprised you're using a drill press. With a decent mill, you probably would've cut your dremel time by 90%.

[@AlikaSEOULROK]

OCD KICKING IN!!!!!!!

[@ameerramchand5606]

careful you get iron poisoning from using that dremel

[@proventure307]

not true

[@loganrickman5243]

Don't do this... go to Atkins. I was thinking about it but David Atkins worth every Penny

[@MegaDragge]

Bridgeport zero horsepower bye bye corner seals. Do you even Know how a Rotary engine works? Me and Mazda do. Do you?

[@deeganmckinley8644]

Bridgeporting actually increases hp due to letting more air in therefore using more fuel and also causes the rotor to be at the point where it lets air in and exhaust out at the same time (that’s where you get brap brap brap brap) and “corner seals” are apex seals. Do you even know how rotary’s work

[@proventure307]

go to speedacademy on YT they are doing it a lot better

[@kaslogan5597]

XD wtf... This is NOT Bridgeport this is rough asf bullshit

[@Sparky210-11]

Worst Bridgeport I’ve ever seen
