Boy is hustling!

Anyone know if he’s on here or have details on the car?

 

It is so real it almost seems to be AI.

 

the ring dorito .......

 

The Ring Dorito is the car owner/builder, I follow him on the gram. The driver seems to be a pro or semi-pro with lots of ring experience. I'm pretty sure that's the owner in the passenger seat, which makes it even more impressive that he's carrying 150+ lbs of extra weight.

 

he is on the forum, spoke to him a couple of times but i dont recall his username

 

Found him on IG. Another Kostas
He has some fun clips there.

 

these friggin greeks are everywhere 😂😂

uncommon name in the states, too common within the greek societies haha

one day i will bring my fd over there and definitely the Spa… life long dream

 

do it! Yolo

i know lots of Greek and Eastern European Kostas / Costas

 

I wasn't sure what "ring" meant besides some random track. After a few seconds I realized where they were. That time is seriously impressive on that track. That time is close to GT3 series times at speeds above 150MPH in sections of the track, from what little I know about that track. Someone please correct me if I am wrong.

Considering, at least one person held him up, the start is at the beginning of the long straight-away and the extra person in car.... wow, amazing run. The first time the car hit grass is a section where some wreck, too. That track will bite you when you least suspect it and even if you expect it it still might get you. An amazing driver, drive-train, and suspension setup.

Cheers to more safe laps around the track!

 

Found an earlier session at Spa Francorchamps - 2:38:

 

Hello everyone!

Thanks to @pgavras for pointing out the thread.

Indeed a member of this forum since sometime but i do not get to post very often as life hasn't allowed me to drive the car as much as i would like!
Got two babies over the last 4 years and developing work means zero time available really.

I am really happy to see that the lap is inspiring as it really is such a magnificent car we have and drive.
It is really mind bending stuff that a 25 year old car can be so good and drive like this. MIND - BENDING!

I am indeed the owner of the car and also the driver at the same time
The passenger is a friend/mechanic who was tagging along on the day.

Just to put some more fuel to the fire this lap was one of the 6 laps that i managed to do on the day and it was a reconnaissance lap, as i hadn't driven the car since i think two years in general, 4+ years at the Ring and actually first time with the Ohlins suspension there.
So each one of the previous lap it we were coming in to adjust the valving on the suspension, check on methanol consumption (as it had an issue on the valve and we had just replaced it) and have a look at the car.
This was the only lap that i actually stayed out for a second lap in a row which meant that the tires were immediately switched on from the beginning of the lap.

By doing some simple time deductions based on experience i would say the car is low 7 as it is now, just from the weight of the passenger, the Porsche, the GTR on the fast back part of the track and also from the two corners i tried passing with 4th gear instead of 3rd to see if the car could do it (it couldn't :P )
When the suspension gets re-valved and on stiffer springs (so it doesn't bottom down in all the compression zones and allows to stay flat until the braking point), the braking will come much closer to the corner as for now the car pitches quite a lot and moves, putting the ABS in play very easily. That alone is a lot of seconds gained as it multiplies by a lot of corners that i now need to lift and coast in order to survive.
The splitter needs redoing and it was also a limiting factor in the drive as in some places it caught air and i had to lift to stop it from oscillating and eventually braking (like it did on the 6th lap). So that is time gained there as well.

And that is with the setup of the car as is right now.
If we talk about a more efficient low end setup with an EFR turbo instead of the 362SXE that i am currently talking then we are talking about a lot of time everywhere as the gearing of the car is super long and it is suffering at the low end.

Anyway, i will stop nerding out with all this because i could go on forever!

Stay tuned as today i will be posting the same video but with data overlay from the ECU which if i judge from myself will be VERY interesting for many people from here as it really offers an insight about how the heart of our car works in such high loads and under so much stress.
I don't know how many times i have watched the video already looking just at the data instead of looking at the drive!

Take care all!
Konstantinos!

 

I have a new PB and video to post for this as well!!

The car has so much potential with the Ohlins on!!!

Video will be coming shortly as well

 

Here it is!

The lap including all data readings from the ECU.

 

@Nabu you are LEGEND!

Re ABS, some have started retrofitting the MK60 ABS. See the later posts in this thread: https://www.rx7club.com/3rd-generati...ne-fd-1156049/

The Engine Coolant Temps and Oil Temps are remarkably stable. Looks like the v-mount setup is working well. I guess there is no thermostat....

 

Nice car and great driving! It's nice to see a well built and driven FD turning laps out there!

 

We need more details!

I assume your boost units are wrong, since 2100 Kpa is.... quite a lot of boost.

Is it running 2.1 bar? Even that seems overly high.

 

I am not sure about the being a legend part but thanks a lot!

The car indeed is not on stock RX7 ABS. We had this switched with a system from a Honda S2000, which i new i liked how it works as i owned one for 9 years and the switch wasn't difficult.

As for the temperatures, i have to admit (between us rotary users here) that it was the perfect day for the car. Ambient temperature was something like 9 degrees celcius so there was LOTS of cool air flowing through those radiators.
Should this be a day in August, i am not so sure where temperatures would be sitting.
We do have the fan starting to blow at around 85 degrees celcius through the ECU if memory serves me well.

 

Thank you! It feels very nice feeling the passion with like minded and passionate people!!

I feel proud to be part of such a strong community

 

Ask and you shall receive!!!

Kpa is actually absolute pressure. The means it includes the standard 1bar of atmosperic pressure which is what we breathe.
So basically from whatever you see there, deduct 1bar and you got your answer!!

I would love to be running 2.1bar though! But i know something that wouldn't at the same time

 

An FD RX-7 approaching seven minutes around the Green Hell IS legendary!


Thanks for popping back onto RX-7Club - proud to have you


Please keep us updated on your progress

Stay safe out there - cheers!

 

Far too kind! Far too kind!
Will definitely try to keep the flag up there for all us addicts here!
Good and bad thing is that everything closes here until Mid March. At least i have some time to decide how i wan to rebuild the front splitter and what i should be doing with the suspension.

 

@ZumSpeedRX-7 I forgot to mention that i like the car i see in your signature! You have a build thread somewhere?

 

Thanks - my build thread picks back up here

All my bells and whistles, and amateur competition licensed time trial racer skills wouldn't get me anywhere near your lap time


Do you have splitter bracing (something like Racebreds) or splitter brackets (something like AJ Hartmans)?

 

Do not underestimate the power of training and the power of a simulator!
I cannot comment on your driving skills (yet ) but i can confidently say that putting the time down to train for something will definitely reward you later down the road.
Its like coding!
The more information you put into it, the better your end result is going to be!

The splitter indeed has some custom bracing we have done. It doesn't have the bracing sticking out to the front but the ones like the racebreads you have linked above.
I think the problem that caused the splitter to break was twofold.
First there was a part on the side of the splitter and in between the lip that allowed for air to sneak in. That created downward pressure to the splitter as speed increased.
The second was ( seeing this in hindsight) that when the welding between the bracket and the sandwich plate in the splitter was made, the AMPS on the welding machine must had been lower than needed and the weld itself stayed on the surface and did not actually penetrate the lower plate.
These are not my words but of a person that had a look at the car and splitter after. I am completely clueless about welding! I am good at holding a steering wheel

Would love for the next iteration to go longer front, longer at the back, more ducting and channels at the front and maybe do something a bit more quick to detach.
It would be nice if the material was more high tech but as the car is still in trial and error mode, i think wood is a good compromise as its more disposable.
For example the splitter broke at around 5KM in from a 21KM lap. I wouldn't be as easy scrapping a carbon splitter for the remaining kms as i was with the wooden one bringing it home.

 

You can increase the strength of a plywood splitter blade without increasing the weight or cost too much by putting a layer of woven fiberglass on top.
