There are still many questions and data to be looked at from these great runs certainly!
TB I just wanted to highlight that the average lateral Gs from 240kph until 300kph (no gear shifts) was 2-3 times higher in the new run from Jussi vs his last run. Your Vmax run (the one that I have) shows also much less average lateral Gs vs Jussi's. It is my opinion that wind direction, tire pressure, alignment settings(camber and toe) and rake are a very significant factor in the high speed stability besides obviously the bodywork.

This acceleration test failed because of strange reason - you'll see

This is a bit better. Speedo almost stays there

I have also another view angle video from this same acceleration. I don't know how to combine them to same video file as side by side you know. If somebody knows a good freeware program for that, please tell.
Otherwise I just put it afterwards separately.

for example best 100-200 with 2 gear changes was 5.15s / 217m and second best was 5.4s.

Wow, Jussi, wow!
Forgive me if I missed it from your previous build threads, but what brake upgrade, if any, did you do?
Protosport, the tuner I am using, based in New Jersey here in the States, just picked up my car today for "stage 2" work this winter to get me into the 700+ HP range.
They use Protomotive tuning and will install GT3076R (up from 2871R) turbo's (Todd Knighton and John Gulino think for my OBDII setup that these work better for my power goals).
However, I am not doing any external aero work or interior stripping (I still have all that factory leather and power seats-and the passenger seat-still in place
), so my car will still be slower than yours-but probably ALL 933TT's are slower than yours.

They are now the choice of professional tuner as I know..
They would be also my favourites if I ever wanted more power but I don't know if I want
But when you car gets also other parts to support those turbos, like cams, twinsparks?, bigger intakes and exhaust systems and enough fuel=more fuel pumps and bigger injectors you will get that +700 easily and you can have even 800 if you want but your engine must have better internals like, carrillos(or else), ARPs, flame rings, welded heads etc and the most important your ECU tuner must be professional to get all works safely and hope he will use Motronic?
Good luck and return back with your results then
I have Movit's big ceramic front brakes, rear brakes are stock ones but better brakes pads..
I'll also install seats back and do interior back during this winter, so the car will be normal driven family car

Congratulations from your choice. Those GT3076Rs with smaller 0.64AR housing are very very efficient ones! They are "better" turbos than mine and you will get more hp with less boost/flow because of better flow capacity compared GT2871s.

This winter, in addition to the turbo upgrade, Protosport will do additional work as follows:
1. Tial Sport 44mm wastegate valves
2. Larger K&N air cleaners
3. Porsche 993 Motorsport solid motor mounts
4. Brake upgrade from 993TT stock (? Brembo)
And here is what Protosport did for my engine build last winter:

Wow! what a list!
Why do you even upgrade?
What kind of powerlevel and accelerations times you have had?
Can you share any AX run data with me, if you have? I can share mine as exchange..
you will have a truly monster after upgrades - believe me!

There are quite a few fast cars out there like this 9FF, it all depends at what boost levels they are running them and how gutted they are. It definitely is mind boggling acceleration though!
I have the following data run from a 996TT, car weight around 3300lbs:
100-200kph: 4seconds flat, distance 170meters with 2 shifts
For perspective my best was
100-200kph: 5.29 seconds and 230 meters with 1 shift and 220lbs on board.
