Here's a quote from the owner on the South African Alfissimo forum....

"What makes this project very challenging, is that we opted to go with a set of individual throttle bodies. With this setup, you can't make the throttle potentiometer (fly by wire) work with the throttle bodies. Dawie had to design and build a pedal box with two accelerator cables (one for each bank of the V6). This proved to be a big job because you have to remove the dashboard to fit the pedal box. On my brother's GTV, we are running with Alfa's Q2 Limited Slip Diff which has a 70:30 split. With 440BHP in the 156, we couldn't run with a Q2, it would simply be too much power for this LSD. Dawie has fitted a race Gemini LSD which has a 50:50 split."

Oops guys did i say 425... it's actually 440BHP... with no supercharger or turbo......... Dawie is a tuning god. Absolute genius..

I rest my case...
