someone needs to send this to PPRE
I just cant understand how PPRE got this all wrong????....like...how did every other big budget build come out awesome yet this one wasnt so?....
Eccentric Motorsports does top notch work and the Richardson's are all around good guys!
Awesome! You guys are mad scientists!🏎🔥
That’s a beautiful conversion in the front. Flawlessly executed 👍🏼
Love videos like this bro, keep them coming.
1:57 wtf did they do to the front of that poor FD?
I built an RX2 4-Door in 1978 that BLEW EVERY local challenger away; Z28
to 914-6, in the East Bay car scene, there was nothing like it. 510's
were all the rage, and my Brother owned several, but NONE could keep up
with my little fire-breathing dragon, that I welded and bent my own
headers for on Racing Beat Flanges, welded the back doors shut, removed the seat, built a roll
bar for, and after I took the Thermal Reactor off, and re-jetted the
carb. It was pretty untouchable to 135 or so and would tach 13k at
shifts, blowing a two-foot flame out the rear. I lowered it, added
spacers, to the wheels, and molded 510 flares on it with rivets and a
heat-gun, painted it bright orange with a two-foot wide yellow stripe
down the middle, It was well-known as an untouchable car way, way before
"tuners" appeared en mass.
914's are turds lol but i know what you mean, this local guy from around me had a 1st gen rx7 that was all built up done by himself running a 750cc carb with 2 stroke oil metering. it was stupid fuckin fast. he was from puerto rico where they love rotaries
Interesting about the machining differences n tolerances you picked up on
Crazy what PPRE sent was 'a job well done' to them. Hopefully chip or someone can start manufacturing the eccentric shafts.
Bernie Mac if chip makes it will probably cost 100k, he thinks he makes gold bars.....and invented the wheel.
PPRE in New Zealand?
@@dirtyd1886 yeah
If you look at the scans, the actual machining was +-1-2 ° off on each lobe so it’s not the machine that was the issue. It’s the relative tolerances between each lobe. So if all the lobes were off by +-1°, the relative tolerance between the first and last lobe would be +-4°. So because the tolerances stack on each other its very difficult to minimize the difference between them, and easier to just adjust for this on the running as they say in the vid.
Impressed with the blue print of the Eshaft and the improvements over the product you were sent originally.
Hi, can't get enough of Chip,s vid. Good luck with your 4 rotor rebuild. Are you aware of any other 4 rotor eccentric shaft that has different eccentric positions, other than all at 90 degrees ? I seem to remember talk of this on the net. Apparently they don,t have the right sound !
Nice to hear that you get new motor done right! Hope the best for building and tuning!
At first I thought I was looking at two Keanu Reeves. I was like, 'I didn't know that Keanu was into Rotories' and then I was like, 'Hey wait a minute! There's two Keanu Reeves!!! Freak'n government cloning mannn!!!'
So nice, hope I see you out on 280 once it's done 👍
Very informative and the attention to detail is amazing. But of a surprise on our kiwi brothers e shaft was out that much have you told them or the manufacturer?
Trent Giumelli yes they say I'm lying lol
I thought the same too....lol but if THIS is the only known failed eShaft from a ppre 26b build, then thats def a 1st for them. Abit silly that they didn't hv you guys send the item back and have it replaced ASAP. Makes them kinda look bad for business
@@dzmazzei but then its good for people like brent curran 😉😉😂
@@rapidfiremuzik_official I would say CBR Curran brothers racing probably use the same shaft manufacturer
@@dzmazzei Why did you choose a 4-rotor from PPRE and not one from Billet Inc. or PAC?
Amazing gotta love rotary
Nice! I love rotarys and the RX family of cars. Four rotor FD's are god level awesome! Looks like PPRE slipped on some details, shame... but looks like you're heading in a corrected direction now! 😁👍
Awesome video man, looks painful fixin' all that fake news.
Excited to see the progress, incredible work
Can't believe the giveaway is still going. Makes me a bit nervous to buy a ticket for it
Adding nitrous to the mix aswell ! Someone likes to partaaaayyyy 😂 for those that missed the hint at the end 😉 i dont miss nothing, great job guys looking fwd to seeing it perform this time around 👍 best of luck
hell yes go Eccentric Motorsports!! they rock love the build Sir
Why is the crank/eccentric shaft built in multiple pieces?
You wouldn´t be able to assemble the engine if it was one piece. With this 3-piece design, you assemble the two inner rotors first, and then the outer ones.
Rob damns is one piece
Thomas Andersen no it’s not
@@MrLikeaboss2012 his is like a crazy custom 4 piece
that last part made me laugh
Great tech, i was in high school when the rx 6 came out and made corvettes look slow. The rx 6 had a reputation of eating it self. Stronger better parts in the new motors. Nice work and videos. thanks for sharing
sam yeates rx6 don’t exist
Rx 2,3,4,5,7,8 but no rx6
good tech coverage, thanks.
Great info David. Something very important to consider for such an expensive engine build. Keep the videos coming bro.
great explanation of everything! subbed
Gracias david and chip !!!
dude has a whole bag of Doritos in stock
Very good video.. Keep up the good work
More videos!! I love your build!
Seriously fantastic! 👍🇦🇺
damn, was guessing the crankshaft was like 0.5-0.1 degrees tolerance or something, but 5 degrees, that's crazy.
I’m in the aero space Cnc industry love to jump one the brige port when ever I get a chance nice car man
What are the apex seals comprised of in 2018?
Is there no definitive reason for the lobe offsets not being 90° because even with a 2 piece shaft 5° is a lot, as is the keyway being 0.4mm out... with the length of the ecentric shaft of a 4 rotor is there 'twist' under load perhaps explaining the fact they arent 90° to one another? Was the difference in angles consistently skewed from one end of the shaft to the back the same way? Be very surprised to hear they werent 90° because of inaccuracys in machining, especially if they were drawn in autocad and run on a 5 axis
laurie agnew Asmira If you look at the scans, the actual machining was +-1-2 ° off on each lobe so it’s not the machine that was the issue. It’s the relative tolerances between each lobe.

@@MegaCoolshot thank you for that
I love this video had to subscribe to the channel nice project
Nice video guys, thanks but, the question I have is.... How much does a 4 rotor or, even a 6 rotor cost to build?
Mad Mike and that factory backed Mazda money must get all of PPRE's attention
What transmission do you use?
Here in 2020 and wanted to see if Mazzei had posted up a response from PPRE on why there were faults with their Crankshaft.
Dope rx7 i hope soon ill have a 4 rotor in my rx8
MOAR!! of this
Did you contact PPRE in NZ and ask for a refund?
No refunds, customer is always wrong
Thats fucked up man. Good on you for spreading priceless information about the scanning idea, and exposing an either faulty product, or one manufactured via tremendous ignorance. Nobody should have to redo a brand new crank shaft. Not many 26B builds in the world. So information and know how is crucial for the rotary building community. Thanks
@@dzmazzei true,i had the same problem here in south africa with a 2 rotor motor
@@dzmazzei did you specify a blueprinted 90 degree shaft and a even firing order.show us ppre response to your claim
what was it like at abels shop?
Always interesting to see a 4 rotor built, must cost a fortune to have everything custom made.
Does eccentric have them shirts for sale?
Oh hey, this guy is also making Tommyfyeah’s 3 Rotor
SnoTheLeopard tommy doesn’t have a 3 Rotor
@@connoisseuroftigolbitts he made a video about it visiting chips shop.
Pumps me up! Love the new camera, and smooth jazz. Hope to see you brapping soon!
Really cool car. I can't get over those porshe headlights, just eeww.
Pretty enteresting didn't know some stuff
Jesus rotors performance doesn't do any of this.. customer service is a joke. The owner is a thief. Glad someone is doing it right. Wish there was a good rotary shop in the Midwest..
I can stare at that Peripheral port 4 rotor all day. lol
Only one guy makes a proper 4 rotor crankshaft Xtream rotaries!!!!!!
what’s the name of the first song?
I'd be happy with a cosmo!!
You paid so much for this 4 rotor, and the engine is no good, you should call the company that made the crankshaft to fix the problem, smothing Like that dont have excusses, I Study cnc machines, and doing smothing Like that makes me hangry, because i dont have the Money to have a Nice car, and you now have to pay more Money to some one fix the problem.
cobratoxic not just that. I run a 3 axis and . 5 axis mill, as well as a 5 axis lathe. 5 degrees is a really big tolerence. If it was 1-2 I would understand because not all machines are totally accurate. 5 is too much
Asmira If you look at the scans, the actual machining was +-1-2 ° off on each lobe so it’s not the machine that was the issue. It’s the relative tolerances between each lobe.

Apex seals 1pc?
Unfortunately for you Americans you don't have the same ingenuity that us new Zealanders have why spend big$ blueprint shaft when it can be compensated by the computer for free
Glad you went Murican 👍🏽👍🏽💪🏽💪🏽🤘🤘😎😎🇺🇸🇺🇸🇺🇸
Would it have been better to buy your 4 rotor from Defined Autoworks instead of PPRE?
Melo DEC you want defined autoworks
Robby Henriksen so these issues wouldn’t have occurred with an Defined Autoworks engine?
Melo DEC I know logan carswell personally and he has my fd right now. If I was buying a four rotor I would go with logan in a heart beat. I think his shop and his personal four rotor speak for themselves....
Logan doesnt make his own shafts ,they come from the same manufacturer.
Don't ever diss new Zealand rotary builders in the 70s a guy called bill shiels built first ever Bridgeport's and periphal ports when Mazda found out they flew him to Japan so he could show them. somehow I think you didn't ask for a blueprinted shaft or you didn't follow manufacfuers guidelines why not show what the reply to your complaints was.if he claimed it was blueprinted then you may have had a legit claim
7:54
Hmmm that engine must cost a lot to build
Those headlights look shit.
That's why you don't trust PPRE FOR YOUR BUILDS
Seriously why would you put the ugliest Porsche front end on one of the most beautiful cars ever made?
That front bumper is super ugly bro
The black 4 rotor is nice not that golden yellow rx7 front bumper
looks sexy af to me 🤔
I Am looks like a fake Porsche
we have widely different opinions of decent lol. thats more like scrap imo
Can you be more specific, which part are you referring to? And why so?
@@dzmazzei the variance in love angle.
LOL, at 5:48 they display the millennial rebel non-conformist clothing and hair line. The doofus twins!
And what have you done of any significance?
