What it's like owning and driving a 4 rotor Mazda Rx7

After Building one of the first 4 rotors in the united states in 2012, it was time to make a video about driving it! This truly one of a kind Rx7, built to be fast on the racetrack, is so much fun to drive on the street too. We hope you will enjoy watching!

[@JohnmillerPowerlifting]

that car sounds awesome

[@GTORx7]

John Miller, thanks!

[@precisionlift4230]

FINALLY something different than “others” Very unique, the sound it makes is orgasmic, for a second I thought it was a motorcycle coming... I know time is the best explanation of all things, rob Dahms Build is something that is also respectable a lot of hype though, but this Build, MAN oh MAN I’ll tip my hat to you sir. This build THERE is NO hype no nothing, no one looking for a sponsor but rather sitting in front of your face. Kudos sir keep up the good vids

[@GTORx7]

I greatly appreciate your kind words! Once it is no longer 4 degrees here in ohio I will be breaking out my Rx7 with its entirely new modifications! Should be fun.

[@moisesvaca8125]

I hope one day if i ever become successful i will try to build a car just like this . I no have originally idea but i believe in this

[@alexkersten1964]

Holy f**king sh*t! This is amazing! Congrats.

[@GTORx7]

Alex Kersten , glad you enjoyed!

[@MrDjcamo29]

Logan C I know this video is better 4 rotor but you will you be interested in building a Honda n600 micro car with two or three rotor the similar transmission and roll cage should be a lot easier if you are message me back in the comments or personal message me if can that would be awesome and where are you located hopefully not too far west coast i'm not the real Donald Trump by the way

Love the fact that this engine has that classic 3:3 misfire on the idle, just like the R26B. Most 4 rotor builds I hear don’t have that classic menacing idle. Nice one!

If I ever go down the 4 rotor rabbit 🐇 hole with my FD, I’d want my 13B-REW put in my NB Miata....

[@Drunken_Hamster]

Time for a fully built N/A 6 rotor build.

[@DrVonDeafingson]

Have you seen the rx4 in new zealand with the NA 6 rotor?

[@Bonercondoner]

Drunken Hamster Have you seen the video with the BMW m6 in South Africa. it has a 6 rotor, shit sounds like Godzilla after taking a big nap.

[@lukesimmons3367]

Too front heavy... Would mess up the weight distribution of the car

[@GTORx7]

A 6 rotor is pretty chunky. Even if using all aluminum side housings it would still add 10" to the length of the motor and 100lbs. In this chassis unfortunately it would ruin the handling.

[@TheLemonArmy]

Logan C you could try and mount the engine further back to compensate.

[@flexgado249]

I want to build a 4 rotor veilside.

[@Earache.]

This is a really unique sound actually what are the exhaust mani specs?

[@GTORx7]

I custom built the exhaust from one end to the other. Uses pretty long primary tubes and joins in to a 4" twin muffler exhaust.

[@franticRX7]

If only I had the 100K to build one.

[@MrZachItalia]

Jason Justin check the website. Starts at $30000 for complete engine

[@KevTheHunter1]

Zachatilla I think he's talking about completely building one. Including weight reduction, restructuring, restoring the shell etc. Haha

[@benjaminloscar5890]

Jason Justin what's there website?

[@NormalCredit-21]

@Zachatilla That's for the motor? Pulse Performance N/A quad rotors start around 70,000. granted those are modified and made using all new parts, but still... For a quad rotor, that's cheap. But to my point anyways: That's just for the motor. Now triple to quadruple your price and you've got a 26B powered RX. This isn't a high end V10 or V12, which are rare but in comparison to a 26, shit even a 20B, are like your dads dollar store V8. This is rotary power, and rotary spelled backwards is "Proprietary and prohibitively fucking expensive". 100,00k is a generous understatement for cars such as this one, and Formula Seven's.

[@itsMC411]

Logan Tanner why does formula sevens sound different with the pulse performance engine? Defined’s reminds me of my Yamaha r6(from the front & flyby), and formula sevens has a different tone. I just watched his new video ‘JDM cruise’ and wondering why. Logan feel free to chime in also.

[@willthetrill4849]

I'm sure you know Rob Dahm

❤❤❤

[@therealpodge]

this is amazing!! I would love this as a road and track car. same power maybe a little bit more refined for the cabin noise. it's an amazing piece of engineering guys! and you are right it sounds very like the 787b. if I wasn't looking I would think it was no.55!! subscribed! also ive noted your number in case I win the lotto as it's my dream build! thanks.

[@GTORx7]

therealpodge, thank you very much. With some more interior sound damping and rubber mounts used on the trans, it would be about there for ya.

[@matthias18]

[@boost3d831]

Mikey I'd even settle for a 3 rotor

[@cdnbluesdriver]

Oh man.....what a machine!! How did you connect the 4 rotor to the Hewland? Custom adaptor plate?

[@GTORx7]

Correct, custom adapter plate to a standard rx7 bellhousing. This winter going 6 speed sequential trans for even faster lap times (should be fun too!)

[@cdnbluesdriver]

Did Kennedy Engineering make the plate for you or did you design/mill it in house?

[@GTORx7]

Colin Hendry, I machined it myself.

[@cdnbluesdriver]

Super cool! Until I'm a machining god, I guess I have to get you to make me one when I buy a 4 rotor.

[@Elnyne]

Really looking forward to your technical video on the 4 rotor parts and sources

[@alicebate6384]

Sounds so good N/A

[@Endisupertramp]

Hi Logan! Can you tell us the firing angles for your car, and do you know if he Scoot or PPRE engines use different firing angles for their 4 rotors. The build is amazing. :)

[@GTORx7]

Fellow Traveler , sure mine is 1,3,4,2. Same as the 787b or 792p. I believe ppre uses the same order.

[@Endisupertramp]

Thanks! The firing angles are equally split I presume, with every rotor firing at 90° angle away from the previous, or? Would that make the 13B fire every 180° and the 20B fire every 120°? Still trying to wrap my head around how the firing angles and timing are done in rotors, there is amazingly little about it online.

[@GTORx7]

Fellow Traveler​​ you have it exactly right. Easiest way to visualize is each rotor= 2 cylinders. 2 rotor =180 degree 4 cylinder, 3 rotor= 120 degree 6 cylinder. My 4 rotor actually is setup in the computer as a waste-spark V8.

[@Endisupertramp]

Thanks for clearing it up Logan. :) Best of luck with the amazing car you've built.

[@joeferreri818]

I REALLY HOPE ROB DAHMS CAR SOUNDS LIKE THIS!!!!!!!!!!!!!!!!!

[@GTORx7]

An Amazing Panda, it will have the same spirit, but turbochargers do not have the induction noise and a softer dampened exhaust note. Just like turbo F1 cars now vs the non turbo F1 cars of the past.

[@joeferreri818]

ok

[@joeferreri818]

Thanks so much rob!

[@GTORx7]

Rob Dahm, exactly. Doubling the horsepower will push massive volume through the exhaust with jet turbine combo. Just two different animals. Please make sure yours does not sound like Mad Mike's! The world will thank you.

[@GTORx7]

Rob Dahm, dang sounded just as bad in person? Well I have no worries on your build, clearly you're a perfectionist with a good group behind you.

[@ElapsusRealitate]

Thanks for the video! Really looking forward to hearing more about your builds. Looking on your website, I'm very curious what a side port 4 rotor would sound like. Would it be more street-able?

[@GTORx7]

The sideport will sound very similar, and be very streetable. But the power is considerably less. Unfortunately the side Port 4 rotor is forced to use very small intake ports.

[@agarcia8800]

now make it AWD and add a 93mm turbo and see what happens.

[@graymatter78-23]

Is it possible to learn how to build these ? I have a lot more questions btw, I'm just trying to keep my comment short
