Default Nissan GTR R35 by Exelixis Motorsport

Aceasta este aventura unui GTR R35“putin” mai altfel.
La origine masina este un Nissan GTR R35 JDM (Japan domestic market) achizitionat de la sediul NISMO din Osaka in 2008.
Standard masina avea 511 cp si 588 Nm.

Aventura de 8 luni pe marile si oceanele lumii s-a incheiat in Noiembrie 2008 cand a ajuns in sfarsit in Romania.
Odata cu masina a ajuns si evacuarea din titan MINES cu tot cu catalizatoare sport si COBB ACCES TUNER PRO-ul .

Dupa montarea evacuarii, prin intermediul deviceului de la COBB masina a fost softata ajungandu-se la 540 CP pentru o presiune de 1 bar.
Banuind ca e loc de mai bine s-a renuntat la catalizatoarele sport in favoarea unui Y pipe + downipeuri custom iar ca solutie de resoftare avand in vedere limitarile COBB-ului s-a ales implementarea unui soft custom de la Piasini Engineering.
Rezultatul a fost unul excelent obtinandu-se in final 683 cp pentru o presiune de 1,5 bar.

Masina a concurat in cateva curse dupa care transmisia a inceput sa dea semne de oboseala

Unhappy Re: Nissan GTR R35 by Exelixis Motorsport

Ei bine acesta a fost inceputul nebuniei, realizand ca se poate mult mai mult a fost conceput un plan ce implica modificari majore dar si costuri substantiale acesta fiind unul din proiectele de suflet pentru Exelixis Motorsport.

Pentru a remedia problemele de transmisie s-a decis inlocuirea internelor cutiei de viteze cu interne produse de catre PPG (Pfitzner Performance Gearbox), iar ambreiajul ales a fost cel de upgrade 900cp+ de la SSP (South Side Performance).
Piesele sistemului hidraulic al cutiei de viteze au fost alese piese furnizate de catre DODSON Motorsport.
Avand in vedere ca nu era vorba de un mizilic precum schimbarea unui pinion pentru treapta 1 a intreaga lucrare a fost supervizata de Glenn Cupit inginerul sef al celor de la DODSON.
Astfel Glenn s-a deplasat personal din Noua Zeelanda pentru a supraveghea acest ‘transplant’ si pentru a oferi un training extrem de valoros mecanicilor nostri in ceea ce priveste modificarea si upgradeul complet al cutiei de GTR.

De asemenea aditional au fost montate atat un oil cooler kit pentru transmisie furnizat tot de catre SSP cat si un watercooler ‘reteta’ speciala a celor de la DODSON.

In ceea ce priveste motorul s-a optat pentru o configuratie unicat in lume pana in acest moment si anume montarea a doua turbine Garrett GT3563R capabile de 650 cp fiecare.

Pentru a tempera puterea oferita de turbine a u fost alese doua wastegaturi externe Tial de 44mm fiecare putand face fata pana la 550cp.

Acomodarea noilor turbine in compartimentul motor a necesitat schimbarea galeriilor de evacuare si asa a inceput colaborarea cu Mihail el fiind ales pentru manufacturarea noilor galerii.
Astfel pornind de la 0 si sudand bucata cu bucata tot ansamblul pentru un flow perfect al gazelor Mihail a terminat lucrarea in 10 zile.

Urmatorul pas a fost trimiterea galeriilor impreuna cu turbinele pentru acoperire ceramica (in cazul galeriilor atat exterior cat si interior), procedeu ce asigura pe langa protectie termica cat si un flow optimizat al gazelor.

Odata terminata aceasta procedura intregul ansamblu a fost montant pe masina si s-a trecut la modificarea donwpipeurilor in concordanta cu spatiul existent si flansele turbinelor.
Desi excelenta evacuarea MINES cu diametrul de 80mm nu ar mai fi facut fata noii configuratii asa ca a fost schimbata cu un sistem de evacuare GTC TITAN tot din titan dar cu diametrul de 90 mm.
In continuare au fost schimbate injectoarele cu unele de 950cc si s-a adaugat o pompa de benzina in rezervor HKS.

Default Re: Nissan GTR R35 by Exelixis Motorsport

Ca sa continuam obiceiul premierelor pe care le aduce aceasta masina ,ei bine a fost echipata cu jante DYMAG din fibra de carbon si spite din magneziu a caror greutate la dimensiunea de 20” este de doar 7,5 kg si cu un set de furtune de racire din silicon Forge facute la comanda in mod special pentru aceasta masina.

Momentan masina merge excelent cu o presiune de doar 0,7 bar dar povestea nu se va incheia aici.

Targetul final al acestui proiect este undeva intre 900-1000 cp si un cuplu in jurul valorii de 1200Nm.

Urmatorul episod va avea ca actori principali intercoolerele Greddy si sistemul Haltech Platinum Pro dupa care vor urma reglajele finale.

See you next time.

Frumos proiect si frumoasa prezentarea!

Am avut ocazia sa vad masina live in urma cu cateva zile si sa am parte de o prezentare la lumina lanternei unui telefon, dar descrierea de aici vine cu un pic mai multa "lumina"

Multa bafta in continuare !!!

Multumim pentru aprecieri.
Momentan nu am masurat masina in varianta actuala dar o vom face dupa instalarea ultimelor componente si dupa finalizarea reglajelor.

Mihail este persoana care s-a ocupat si se va ocupa in continuare de tot ce inseamna sudura pentru acest proiect, in acelasi timp este si un prieten apropiat al nostru
Beck, nu am inteles exact intrebarea daca se poate sa detaliezi.

Frumoasa povestea.
Dar mai interesant este proiectul.
De asa ceva avem nevoie in RO.
Succes.
