I have changed the wheels of my alfa, in this case fitted a Sparco Assetto Gara, it's a light wheel compared with the 7 spoke horseshore. This ones weights 9.12kg and the alfa 13.16kg each.

Because lightweight wheels make diference in acceleration i decided to make the exact same tests and show here.
It's doing good.

Only issue is your not using either Dragy or Vbox for those measurements.
They could be slighly downhill, and more than likely stopwatch not started at exact km/h, since speedo will always show incorrect.

So yours "non validated" best times is:

60-100 km/h 3rd: 3.06 secs
80-120 km/h 3rd: 3.65 secs
80-120 km/h 4th: 4.86 secs

Vs the validated Dragy runs from my old K04 TBi:

60-100 km/h 3rd: 3.08 secs
80-120 km/h 3rd: 3.31 secs
80-120 km/h 4th: 4.38 secs


You should really get hold of a Dragy or Vbox to confirm your runs.
Then do an a additional 50-130 km/h measurement and post fastest time possible.
The 50-130 km/h time gives a really good indication of a cars power.

My K04 159 TBi
50-130 km/h : 6.66 secs

Wifes old Alfa Romeo Giulietta 1.4 MA 170 TCT
50-130 km/h 10.4 sec.

My new stock Giulia 2.0 TB 200 hp
50-130 km/h : 8.88 secs

why don't you measure 100 - 200 times?
Easy :)
Nowhere to drive 200 km/h in Denmark legally. Max allowed is 130 km/h.
Try the 50-130 kmh and you get addicted to it. It's a really good way to measure power.'

In Dragy you simple go to "Custom Mode"

Let us know what you got...

Which gear for the 50-130?
Whatever neccessary. You could do a 0-140 and then measure the 50-130 km/h time.
Much easier would be coasting at som 20-30 km/h in second and using gears to get to some +130 km/h. Then grab the 50-130 km/time.
Using stopwatch and speedo will not be valid (but give an indication)

It's not legal to have a bigger turbo also haha :D

I borowed dragy from a friend, did a few runs but only one alone and at the end I had upward slope...

at least do up to 150 ;)

my car spins 235 19" tyres in second if I slam the gas so no point in measuring...

It's another discussion but actually - yes it is (at least in Denmark)
You're allowed up to 20% perfomance increase from most powerfull version, as long as brakes and wheels are same.
159 3.2 makes 260 hp so up to 312 hp on the TBi as it have same brakes as the 3.2.

What are you driving?
100-150 km/h in 4.35 that's pretty fast. Much faster than even a modded Giulia Q4 280hp

My TBi did that in 100-150 km/h 5.99 (dragy)

Good for Denmark :D We have shitty laws for car regulation...

I drive a Giulietta QV with the 240 turbo, FMIC, open intake (AEM), full open exhaust (Ragazzon), Turbosmart diverter valve, quaife, remap, etc....

yes, it's pretty fast ;)

Did you make some other tuning since this video?
In this video 100-150 km/h seems more like in the 6.0-6.5 sec range

if I look at my tacho - 100-200 is 11-12 secs ;)

Yes please post a video of your Giulietta doing 50-130 km/h and 100-150 km/h incl. dragy results.
Just to compare:
I beleive 100-150 @ 4.35 sec in your Giulietta would be faster than a 450hp Audi RS4...however your Giuletta does 100-200 kmh in 12.72 sec where a Audi RS4 does it in 10.4 sec..
