Sounds nice!

Will you be putting them into production when it's tested?

yes, this is the goal

more info on the shifter? any pictures? of what is in the car now that is.....

[nervas]

more info on the shifter? any pictures?

I will post more info, when I'll get it working

of what is in the car now that is.....

what?

[speeding-g60]

i saw the shifter in the video.... thats what i wanted more info on... the shifter you are running now.

[robertass]

English please

I guess the other cars are not the same power as audi on that vidoe

there was 2 shifters in video, one home made, and the last one Audi Motorsport shifter, that rocks!!!

[nervas]

I guess the other cars are not the same power as audi on that vidoe

power is not the most important figure in racing (bigger engine = higher weight), but all cars from that video is from the same Baltic Open class.

Hello Nervas,

You was posting that you are interested in competing in the Dutch Supercar Challenge, do you still have these plans?

Hello Nervas,

You was posting that you are interested in competing in the Dutch Supercar Challenge, do you still have these plans?

there is such plans, still need to get the right budget for next season

[Evert Thomas]

Yes budget is always en difficult. We have also got the time attack series in the Netherlands. Would you like to race also at one (or more) of these time attack days when invited?

today we blew 2 rear diffs.. in very twisty Latvian Bikernieki Moto track with a lot slow speed corners..

The first one was with V8 torsen and now there is a hole in diff cover..
So we called all Latvians we knew and bought another diff and changed it in 2 hours (with the time that took to get the diff to the track..) it was without torsen and there was a lot wheel spin and bad understeer without torsen.. this new only lasted 2 laps. got stuck and locked both 2 rear wheels at speed 180+km/h... but nothing bad happened just 4wd drift

I gues next HIGH priority task will be to put diff oil cooler (that was on the todo list for next week)..

here is video on the straight made by iPhone, will post some pictures and video later from cockpit..

bu the way, performance stats with low boost from datalogging:

speed - minute:sec.milisec from datalogging:
80km/h - 2:09.39
100km/h - 2:09.99
120km/h - 2:10.39
140km/h - 2:12.13
160km/h - 2:13.54
180km/h - 2:14.82
200km/h - 2:16.90
215km/h - 2:18.3

Do you think that the rear Torsen broke because of diff oil temperature?

100-120 in 0.4s is insanely quick, that is half the time of a Porsche GT2 RS (620ps and 1370kg), Carerra GT (612ps) and RUF RT12 (650ps).
80-120 in 1.00s is also outlandish and would indicate well over 1000hp if in a typical street driven car (1500-1650kg). For example, the 997.2 Turbo S (530ps and 1570kg) goes 80-120 in 1.9s
However, 100-160 in 3.53 and 100-200 in 6.91s is more typical of normal weight road cars with around 550-650hp (Ferrari 458, Lambo 570-4, 997 Turbo S, ZR-1, Ferrari 599 GTO, etc)

What is race ready weight with driver, current power/torque, gear ratios and what is the rev limiter currently at?

I am building a diff oil cooler set-up for my torsen rear diff - using a pump and cooler from a 200sx, these are easy to get hold of and should work well for a street car.

Mocal also make an electric oil pump for this
