I have been a fan of Autodelta for a long time, they make Alfa Romeo into beautiful sexy beasts.
This replica is based on Autodelta Alfa Romeo 147 GTA 3.7 Selespeed version with 1st stage power 328HP.
I researched quite a lot to get as accurate as possible replica. My aim is not only to replicate the specification, but also the handling and behavior on the limit
Power is at 328HP, with torque at 266lb-ft, the real one is 260, so it's as close as I can get. Weight at 1383kg based on real car weight tested by auto magazine and weight distribution of 66/34, it may sound bad, but this car is still superb.
Suspension is Autodelta Sportsline Corse Coilover Kit, with front 130N/mm spring and rear progressive spring from 42.5 to 60 N/mm, in GT6 - 13.26kg/mm front and 6.12kg/mm rear. Damper has been setup for maximum traction under heavy braking and balance on mid to high speed cornering. The real Autodelta suspension kit uses INTRAX HDA Kit as their source, which offers outstanding performance and reliability.
LSD, the horror of massive torque FF engine, torque steer, with this in mind, Autodelta made special LSD which offer progressive action near the limit and 30% maximum lock. This gives minimum torque steer on low speed, and still offers good traction and maneuverability.
As this is Selespeed version, I have to correct the gear ratio, the Autodelta 147 GTA should be able to replicate the real car top speed at 280kmh.
I tuned and tested at Tsukuba, Silverstone GP, Brands Hatch GP, Nordschleife and Fuji Speedway F.
When tested at Tsukuba, it was capable of 1:06.3xxx lap on comfort soft with ease.
Below is the car in action, driven by Jano Djelalian, the owner of Autodelta, who owned and built the car.
ENJOY
