425 BHP Alfa Romeo 156

Built by none other than Dawie de Villiers of Glenwood Motors in Pretoria, South Africa....

Contents;

3.2 V6 GTA engine with 3.8 big bore kit, comprising 12:1 Ross forged pistons and Pauter conrods.
- 304 degree cams
- Solid lifters
- Twin vernier pulleys
- Bigger valves with 3 angle seats and spiralling
- Cylinder heads ported and gas flowed
- All rotating parts balanced
- Individual throttle bodies with bigger injectors
- Two custom plenum chambers (see your picture)
- Gotech engine management
- Powerbrake custom billet aluminium calipers with 330mm grooved and drilled discs and race pads
- Eibach springs and Koni Sport shocks
- Front and rear seats removed
- OMP kevlar seats in red
- OMP race, suede flat bottom steering
- OMP 4 point quick release harness
- 17" black wheels with Bridgestone semi slicks
- OMP strutbrace
- Zender front and rear bumper (rear bumper modified to suit sedan)
- 156 Ti sideskirts
- 156 GTA smoked headlights
- Grille shield made black

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...

Re: 425 BHP Alfa Romeo 156

Surely it would be pretty much undriveable below 30MPH?

Maybe, with those wild cams.. I wonder if the car will even idle?!

Maybe you'd have to stay in first or second to keep the revs up..

Why ya say that?? It has proper quality gear in it forged pistons pauter rods and more. It should be able to be driven to the redline all day long with out a problem. And if the engine was built correctly it should be fine the only problem that would kill the car would be a dodgy map from the engine management but I doubt Glenwood don't know what they are doing since they are doing it for so long.

Re: 425 BHP Alfa Romeo 156

Stephen, i noticed you managed to get all the specs of our Alfa 156 from the Alfissimo forum . For those that asked whether this 156 is being raced, well most DEFINITELY. It was purposefully built to take on the new BMW M3 V8, Audi RS4 and Mercedes AMG's SLK55, E55, CLK63. It is also being used for the occasional 800m drags and track days. Here are some more piccies.
