One horsepower today. Fine Jona for litt avslapping etter skumle Halloween hopp.

På søndag var vi på Grenland å fikk tuna inn chassi , clutch å motor til MM Motorsport sin Raske Ford Puma. Nye aero pakka fungerte også veldig bra. Endelig blir det turbo lyd , flammer å masse lyd i rallycross kl 3. I morgen drar vi til Trondheim da første nm runde skal te**es med alt nytt. Liten smake bit fra test starter.

Da har vi endelig fått sendt ut mange Bmw Dct elnett til de nye F serie gen 2 girkassene. Det som er veldig smidig her er at de nye netta har ferdig obd plugg med medfølgende xhp obd flash tool som gjør at ikke TCU må sendes hit for programmering. Vi har levert justert Dct produkter som har gått i norsk racing tidligere og det fungerer utrolig bra vis alt er justert korrekt. Dette er en bra og rimeligere løsning en konvensjonell.sekvensiell girkasse som trenger hyppig service. Med økt intern oljetrykk har vi bremsa 900nm uten slur på org lamell pakker.

Christmas friendly colour of exhaust when doing full als adjustment of this mint Audi S1 with our innhouse build 2.2 high rev flex fuel drysump engine with about 840Hp and plated diff set up to tarmac. Offcource loaded with race , pdm keypad.

Happy Christmas and a happy new year to all of our friends, sponsors , customers and dealers. In 2023 we will do some cracy stuff so stay tuned 😀

Vi har blitt spurt om vi kan poste litt av hva vi gjør og driver med her. Beklager dårlig oppdatering av hva som skjer her men idag for 1 time siden ble det laget en kort film rett på sparket uten noe manus. En lang drøm gikk også i oppfyllelse idag da et spesielt prosjekt ble ferdig bremsa.
Et riktig godt nytt år ønskes alle våre venner, sponsorer, kunder, forhandlere og samarbeidspartnere.

Nå som racing sesongen var ferdig var det rett ut av henger og rett i dyno med Audien for og planlegge neste års racing satsing fra Gt3 til Gt1 som er opp nesten dobbel effekt fra vi har kjørt før.

Med hardkamma turbo motor som kan dra 10 000rpm setter det store krav til korrekt turbo med unaturlig stor turbin del. Etter testing av ulike billet turboer fant vi en perfekt turbo vi skal bruke neste år . Bilen må breddes 16cm med tilhørende store dekk og bremser oppgrades. Håper ikke vinteren går alt for fort. 😀

Yes. We are now Norwegian champions in the Gt3 class with our Audi race car with as driver that won the title. It have being a tough season with 18 races, but he manage to pass a porsche 997 cup car in the last corner before finnish in last race Rudskogen Racetrack this weekend and secure the missing points.

We have sett track records on all tracks in Norway in the Gt3 class. 1.26.1 Rudskogen. 55.6 Våler. 1.13.0 Sokndal.

Thanks to our Sponsors that belive in us and help us.

Maxxecu / Maxxtuning AB V1 ecu was the first ecu type that started it all. We have used this ecu in our race car since 2013 without a single issue and change to Maxxecu / Maxxtuning AB race ecu these days. Reason for change is removing old wire butterfly with new modern fly by wire throttle .
A big bonus is also that sechvensial gearbox will be totaly clutch less during racing. It is 18 races this year, 12 races done and 6 races left in the gt3 class. So far P3 in our class and setting gt3 laptime records on all tracks in Norway with this old ecu 😀
Our goal is to win the gt3 championship but it is only 2 weeks to next race, but now our car have big damage in chassi because another car hit us 3 times in last corner before finish last race🤨🤨🤨🤨🤐🤐

Hope we manage to get it ready to next race.
