Hey Rob,

Was nice meeting and chatting with ya for that small bit of time I had on my lunch break! I got tied up with work later on so I couldn't stop by. Would love to see the car next time!

crashunit007 03-27-17 03:26 AM

Dude I know I've been out of the 7 game for a long time, but never did I ever dream u guys would be dropping 4 rotors in the FD. You guys are fucking nuts, I fuckin love it. Love your vids too Rob, makes me want to sell my kids and get another FD!

Ha - I'm a deleted member, awesome! ��

That's actually quite ugly. Reminds me of a Cadillac

Care to elaborate on which parts of it you find ugly? (The Furai part?)
..If so, you'll have to get with the Mazda design team on that one.

I think Rob has a Cadillac CTS-V daily driver so he might actually like that aspect if true, but I'm not seeing Cadillac anywhere in the Furai design myself.. (They have been doing great with their latest designs though, I must say..)

Yes; here's a see-through fade to show how it lines up with the actual FD front end:

To each their own, but I think it’s ugly like I think the veilside is ugly lol Yes mazda screwed up on the front. I’m aware it was it’s design. People are. Trying to take simplicity out of lines. Pretty lame.We all have our own tastes for sure.-Nick

The front end is ugly. What is it trying to be, the bat mobile?

Dude seriously.. I think your opinion has been made known. Your 2 cents have been registered

Agree with broke a baller. That shit is ugly as sin.

MattGold 01-02-18 09:14 AM

I personally like it. Good call back to Mazda as well.

If you guys aren't familiar, the Furai was a three rotor concept Mazda put out 10 years ago:

jojodotcom 01-07-18 07:47 AM

LO7 can you photoshop the RX-Vision front end instead? I think it would look even better than the Furai~

Any Mazda or Rotary or FD nut needs to know about the Furai. Simply amazing and jaw-dropping, and I still haven't forgiven the goons at Top Gear:

Here's a modified nose version with extra intake ducts, plus sideskirts and some extra finishing touches, as well as an RX-Vision version as per (edit:oops) Jojodotcom's request:

top rendering reminds me of an Aston Martin. If there was an actual grille opening on the bottom rendering i think it will look a little more realistic, but by god it does look sinister! :icon_tup:

ptrhahn 01-08-18 08:45 AM

The Vision 'shop actually looks pretty good... better than the FEED front in my mind, based on the other changes Rob made (rear flares, longer hood. The Furai was neat, but it was basically a modified ALMS car.

True piece of art...

photoresistor 01-09-18 08:27 PM

I love the look of the furai... but I don't think it fits very well on the FD (nice photoshop tho).

haha i questioned the time at first then i just hit 181 without a tach last week. I just posted a dyno video of the 3 rotor. We detuned it from that for reliability in the desert. about 860 whp.

The 4 rotor is progressing nicely. Slow A F, but progress nonetheless. The entire drivetrain is in. Ill get pics of it out of the chassis, its just beautiful. Finishing the rest of the tube chassis finally.

Still waiting on a machinist to install snap rings in the rotors. Paid for the service in August and have yet to receive snap rings. We will be dynoing the engine outside of the car. Partially for BHP insanity and partially to measure how much the drivetrain robs horsepower.

Gilgamesh 05-04-18 09:19 AM

I could live with the furai look...

This project is getting so far away from an FD that you might as well call it something else.

I always wished I had an engine dyno for my own experimentation. Can't wait to see the results!

Oh yea, did you get your 4 rotor e-shaft blue-printed? Monsterbox had inconsistent phasing issues with his and his e-shaft may have come from the same place yours did if it came from New Zealand. His was + or - 5° off on each rotor loan.

The Spyder 05-08-18 01:05 PM

Rob,

On the 20b, did you upgrade injectors from the 1050/1700 combo before the 950hp pulls?

TwinCharged RX7 02-28-20 01:18 AM

Doesn't get much better than this.



pjr 02-28-20 06:11 AM

Watched it yesterday … following for quite a while; despite all the detractors and naysayers and issues, he's made tremendous progress and I can't wait to see that thing with fenders on it rolling on the street!

Zepticon 02-28-20 06:13 AM

i think this worklog needs more updates and dedication from everyones favorite hairloss restoration peddler ;)

chino_rx3 02-28-20 11:32 AM

Best Rotary You tube out right now 👍🏼. Way to go rob, snapped a pic of Rob’s comment on my IG 👍🏼

Congrats on surviving the car's first big race.


In case you're thinking about Bonneville or El Mirage soon, I've heard their tech inspection is very tough. Good idea to get in touch with some experienced land speed racers before building bodywork, to avoid tumbling like the Racing Beat car did back in the day.

We should be fine once we get a few more upgrades done. I will have to look up the new rules as its been a long time( I did tech inspection over a decade ago for a big event).

Hey Rob, I have some connections down in FL with the import drag guys. They can fix all the issues you have with the hood and the body panels. Just send me a PM and we can talk!
