I visited a few websites of Alfa 155 owners recently, and noticed most have made modifications to their cars, ranging from tyresize to chiptuning, etc...

I've compiled a little list of changes I made on my '92 2.0 8v

- EBC gold range groove brakepads combined with Sparco T-51 brakepads, all around. The pads it had heated too fast and never did have the bite I wanted. This combo works great.

- K&N 57i induction kit. I stilml have to modify this a bit, I don't like the location and small size of the filter.

- FK Königsport suspension. Front + rear adjustable in height and hardness... Also a good combo for handling, but detrimental for comfort as was to be expected.

- Supersprint exhaust excluding the manifold (original still) and the last damper (Remus). I made these changes in steps, starting with the cat replacement. Gained 6 HP on the testbank.

- I had a custom ECU made, with the rev limiter 300 RPM higher, and now 164.5 DIN HP at 6200 RPM and 213.8 Nm at 5200 RPM on the testbank, measured on the wheels and calculated back. Anyone else got any figures about his car? Mighty curious....

- A spoiler on the trunk, to keep the back end in line at high speed. It's the standard spoiler from a Ford Escort RS2000 ('92-'94)

- 16" rims and Goodyear Eagle NCT5 205/50 R16 tires. They are actually too big for the car, so next time I'll get 205/40 in front, 195/45 in the back.


What I need to change:

- The steering rack. I want a more direct version. 2.5 sounds good to me. Anyone know a retailer who can sell me this? The one I got has a knick in it, MOT will find out sooner or later...

- The bushes on the wishbones... Powerflex ofcourse.

- Would like to get the flow improved inside the engine as well, together with replacing all the bushes and bearings.

Cuore_sportivo_155, back to work...

Ok, looked them up on the net... Do you think it'll help me reduce the flat spot in the torque between 3100 and 3800 RPM, and the massive fall after 5000 RPM?

Here's a picture of the printout they made when I got my new chip. february 3, 2004. It could definitely be a lack of fuel, surely the drop off after 5000 RPM. Any thoughts anyone?

EDIT: Blue = torque, Red = power on the wheels, Yellow = engine power, Green = dissipate power. Would be best to know...

your power curves look fine to me. they are very similair to the graphs on www.squadra-tuning.com

the FSE valve would help the flat spot. it did on the Silverstone.
was the car run to the rev limiter when on the dyno ??? if the tester lifted off early that'd give the sharp drop at 6000rpm.

My Silverstone reached max power at 6500rpm and didn't drop off as quick as you graph. The FSE wouldn't cure that if it is a problem. if the car was being starved of fuel up there, you'd probably see a flat curve as the car would stay about the same power I would have thought.
