Zed's supercharged BRG 97

[Zed CZ]

Next race was two months away and I had time for doing some rests and upgrades..

My old roof had bad zipper so I was aware of the rain and mainly because of that I've bought a new roof out of ebay some time ago but wasn't brave enough for doing the job, until one day.
Now I know it wasn't job for me, next time I'll rather pay for it than doing it by myself
But in the end I made it and the roof is working properly..

Don't have much photos of the progress, only this one after drilling rivets from the old one and prepared new one for rivetting.

Thank you for all the great photos and video Zed. It is very interesting to read about a true Czech Miata enthusiast.

I've had an opportunity for standalone ECU, DIYPNP MS2 with all the stuff like wideband lambda and MAP sensor and I've thought it will be great next step if I want to do anything with the SC setup and learn something new to me.

One friend with MS turbocharged NB gave me his help on one hot saturday and after a lot of soldering and checking what we've forgot it was ready for loading a base map and the first start, everything was working well and running, success, but we've ended up pretty exhausted and late in the evening.
The tuning part is different story and till now I'm not fully satisfied, it was better with the powercard, but rolling road tune will come soon and I'm looking forward the results..

Next were new coilovers, after many referencies I've chosen a set from BC racing, BR-RS series with springs 6/5 kg/mm, they were lovely and compared to TATechnix looked more functional too.

When I was there I've changed brake hoses from old rubber ones to new teflon hoses and also changed up brake fluid to ATE Blue racing.


All done

The ride quality has improved a lot, they are not as hard and bumpy as TA, but the track will say more.

[Zed CZ]

Thank you guys, I appreciate you've read all that, more will come... And sorry for my english, I know it's a bit gritty

[WASABI]

Great story, pictures, and video so far Zed! I love the new tan top and am excited to see what the new suspension will do for you on the track.

Then there were another two Miatacup trackdays (2nd and 3rd out of 4), both at Vysoke Myto.

At the 2nd Miatacup race I was really struggling with my tune, the car didn't have power, SC was screaming normally, but it was running like a N/A, mostly due to too safe ignition map. I've ended up 4th in my category. In the speech of time I was overall 7seconds quicker than last year, but I could be even quicker..

At the 3rd Miatacup race I did some changes to the tune and it was better, quicker revving up and more power at the peak so I was hoping for better performance. Sadly it has started to rain during the day and the race was wet. I had to change the wheels back from slicks to XXRs on AD08 which were at 30% of life at that time so no chance for a good position. I was 5th in category, but in overall standings I was 2nd after this race for my suprise, many of my "rivals" were worse than me.. First 5 drivers between 7 points before the final race

and a wet carefull onboard - 2nd and 3rd lap had the same time, and at the first turn in 3rd lap I missed my throttle when braking and locked rears a little

[Zed CZ]

Thank you WASABI and as for the new coilovers I forgot to mention. It's more predictable, better weight transfer, but not as hard as TA even on the strongest setting, maybe I should get harder springs in the meaning of trackdays, but I'm satisfied with it. On normal roads it's far far better, more comfortable, not so shaky, with better response and I have to say more fun to drive.


In the meantime before final race of Miatacup I've visited one of our big adult circuits at Brno for my first time (you can know this circuit from MOTO GP). It was public driving so quite a lot of cars and drivers who are learning the track or with the car. But I had a great day out there even with 3hours highway drive in the very hot weather with some traffic jams by the way and I nearly missed my place, but all was good by few minutes in the end...except for the suspension which I forgot to stiffen up, but could be worse...

Your Roadster looks great Zed!!!!!!!!! Nice and Clean...........

[Zed CZ]

And then there was the final race of Miatacup at Pisek, which I like the most of those three tracks, it's just superb (look at the video). As I said there were 5 drivers between 7 points so kind of drama ahead in the meaning of winner takes it all.

I've made my best and... it wasn't enough, by 0,04s I've ended up second and second overall, but I was pretty happy, my first complete season and second overall. Great day again.
First was a guy with NB with MP62 supercharger running on E85 and about 200rwhp, so not that bad to be that close to him.

[WASABI]

That looks like a beautiful track! Did you make it into 4th gear?

[Zed CZ]

No 4th gear on that track, only 2nd and 3rd, same as the Sosnova and Vysoke Myto, as I said, those tracks are mostly used for karting, motards and some car enthusiasts which can't afford to rent a big circuit


It can look like I was driving only at tracks, but I used her for trips too, just wasn't shooting the photos..
It's great to have an opportunity to just sit in the car and drive away from work to clear the mind up in the huge space above and relax.

Finally I made it to the end of season 2013. My goal at start of the season was to drive at all of our circuits and tracks, mainly for personal references and base lap times. One circuit was still missing, it was Most and on one fall day I've reserved few stints at a public driving. Sadly there weren't more of us, mostly I was driving solo, but nevermind, I've been there for the first time, so it was even better to have the track for myself and I was satisfied with it.
It's quicker circuit than Brno with some tricky turns and I liked it a lot.

There is an onboard from second run:




And in the speech of numbers, season 2013 was about 8k kilometres long (about 5k miles), more oriented for trackdays with 8 visits in total and with lot of things in my mind that has to be done.

More will come soon..

you didn't tell me you're starting a build thread here lol

how about some update from last week, huh?
