"I need to know how to be a better driver in order to dictate how to be a better builder" people can trash talk you all they want, but they can't trash talk your mentality. You might take some wrong turns along the way but you never waste an opportunity to learn and do things better yourself. Well done!

Typically trash talkers are lazy people who have time to trash talk because they have nothing else to do. People who achieve anything fail more then they succeed. They get back up and try again learning from their mistakes which will lead to success.

This thing is relentless… never seen an RX7 move so quickly without being 100% drag-focused. With a full time attack spec aero kit this thing could be a record breaker (if it isn’t already)!

There are no words for this car, utterly speechless how crazy this thing is

Soften your front suspension and it won't understeer nearly as much. You really want the nose to drop into a corner to the point where it's almost touching. That maximizes your front air dam, and it transfers weight to the front tires. With good geometry, it will also increase camber and effective pivot offset. Even with sub-par geometry, the weight transfer and additional camber/pivot will help alot.

And just think that it can get so much better from here. A scary thought😏

Couple of tips from an old track rat: who tracked highly modified FDs for many years. Def need aggressive sway bars and urge you to go very high on spring rates. My 2750 wet FD back in the early 2000s was running 1000 front/650 rear rates. Chassis came alive when I went to high rates. Other FD track friends followed suit. About brakes, we ended up totally bypassing the Mazda ABS pump and went full manual with bias-barred twin primary cylinders. Hope this helps your thought process. Love the build.

@nicolelongneckergallery

Replying to my own post... lol... ALso, your comment about no ducting reminded me that I hand-fabbed very tight radiator and twin oil cooler ducts on my nose to help cooling AND add front downforce. I ran the Mazda GTC front end (bodyworked out the square license protrusion) and a flat aluminum nose tray splitter. As you can see, your car is nose up at speed... you can fix that to reduce understeer. This chassis is very neutral by nature.

@x808drifter

Жыл бұрын

But since this thing no longer runs anything close to stock style suspension the rates are gonna be completely different. It'd be closer to an open wheel suspension at this point. Him being on drag slicks isn't helping either.

@jantorep

Жыл бұрын

Agree on this. Get some penskes or somethig like that built for the car with correct springs and valving. Then add adjustable swaybars. And make sure the chassi is reinforced under the tunnel as well. And ofc proper slicks or street slicks will make a huge diffrence. And the car should be abit higher in the rear to add more weight forward when braking. Also the massive wing will give you understear. So make sure to work on the suspension and geometry to give you a good balance. Once you get the hang of the car with awd you should be able to go much much faster with a slight oversteer.

So cool to see it taking a full beat down! The MT tires are a HUGE disadvantage. I realize you're worried about hooking up the power, but drag tires don't make lateral grip. So that is making your understeer issue even worse. The Hoosier A7 would have been my choice for this. A couple laps to get heat and they would have blown your mind. Looking forward to seeing you keep shaking down the car!

This is amazing to see!! I would like to say. Next time you tune, if you have the time, tune with the throttle at intervals of 5% so you can tune light throttle advances.

I think they already are. Atleast under all rotory guys, everybody knows this car. There are other great 4rotors, but not everybody knows them. (Mazzei Formula for example, who is now building a new awesome project)

I'm just gonna point out the elephant in the room. Rob you are an excellent driver, and the 4 rotor has incredible potential I just think at times too much time is spent on the engine and drivetrain and not enough time has been spent dialing in suspension geometry etc. To get a better feel for the car I think you should detune it to maybe 500-600 and really get it set up at a lower hp so you can get everything feeling good then slowly ramp that power up🔥

First words out of my mouth on the intro pull..."Oh my fuck." Rob...it's happening. It is coming to fruition. It's beautiful, love to see it.

I’m so happy to be able to witness this transformation. Rob you are rollin with the big boys. Amazing clip.

First thought that hit me though, as I got nervous every time you took your hand off the steering wheel to shift, have ya considered paddle shifters?

There is so much progress over the years, good job guys. Datalog from monitoring tire temps across width of thread could help with tuning up correct camber too. (understeer could mean it needs increase of front camber?) And ofcourse as Rob mentioned ARBs(swaybars) would improve handling masivelly too and increased tunability of suspension for tracks.¨ For that power it handles decent. Keep going sky is the limit. 👍

Rob, be proud of yourself man... that car is a beast and you built it yourself, I think most of your fanbase are proud as hell to see the car doing what it does, the fact that the show matched you up with the car and driver they did speaks volumes... take a step back for a minute and look at what you have created through hard work, endurance and sheer tenacity. I'm a wheel aligner, wind as much castor on to it as you can get, then give it another turn, -3 to -3.5 neg degrees of camber and 4mm toe out up front and it should grip up bit more, or.... you being a big old nerd could look in to ackerman angle, bump angle, and corner weighting, and you would have a much easier time in the seat, but it looks and sounds like a blast to drive.

An earnest passion for motoring, and the guts to keep going through growing pains will keep fueling the fire for this rotary beast.
