What happens with your injection quantity above 2600rpm? It drops from 89mm3 to 80mm3 instantly?!? That must be quite noticeable drop in torque...
Also your turbo control could use some tuning... It over-boosts over 3bar quite badly. You are requesting too much boost in lower revs. Requesting too much boost in low revs (below 2200rpm) always ends up in big over-boost.

Anyway your question was about power. If you didn't alter the injection duration maps in a "bad way" and the 80mm3/inj is "real" number. Then my bet is 180HP. And around 380Nm below 2500rpm.

But there is quite some reserve left if you ask me. In the area between 2600 and 3500rpm you are running with AFR above 20:1. You could drop that close to 17:1 quite easily and still have very low amount of smoke.

If you will succeed in raising that IQ then you could be close to 200HP with 90mm3 @ 4000rpm. And probably around 450Nm @2500-3500rpm with 100mm3/inj.

Around 2 secs faster than my previous 147 JTD 8v with 160 Hp:

So I guess 180 HP for your car seems realistic.

I think you are a bit too pessimistic here JS.
Easily 20% shorter time of acceleration and only 10% increase in power? I'm quite sure that his car is producing more than 180BHP.
AFAIK he is injecting 100mm3 through most of the rev range. At least from what I have seen in his ECU map... I havent seen the logs yet.

Under 8s from 100-160 also speaks for itself... AFAIK there was a Dutch fellow here with hybrid turbo on a 16V engine with measured 190BHP (at squadra dyno) and his car was timed just under 9s from 100-160. Right?

My guess is that he is around 200BHP.

I see around 3 seconds faster than yours 100-160 (7vs10) . The real inyection is +90mm3 the data log not show a real values beacuse a "bad" tune. Next step 110mm3, 2bar boost, 1750bar rail without inyectión limiters.( Thanks Gregor)

Well ofcourse it's hard to say based on a movie.
If he indeed has 100mm3 up to 4000 rpm I believe he's close to 200 hp.

The Dutch guy (Gino) indeed did around 9secs 100-160, but in 5th gear!

This Punto only has 5 speed gearbox... compared to 6 in 147. It is harder to compare, because 4th gear on 5speed is somewhere between 4th and 5th gear on a 6speed.

But in any case it is very fast punto. And hopefully it will get faster when Victor manages to fix the mess inside his ECU

6speed box is only a few km/h shorter in first five speeds comparing 5speed box (at least on C530boxes). See my gearbox table - https://www.alfaowner.com/Forum/tunin...ml#post3843547

Yes, but is the Punto gearbox the same as in 156/147 ?
If not, then it's very difficult to make a good comparison since the rpm band is different.

But Punto is much lighter than 147. Respect, it´s very fast. My GT makes 100 to 160 for 10s. But I run lower IQ in low rpm and peak is 90mm3/inj. OEM turbocharger.

in case of alfa 1.9 jtd 5 and 6 speed, the first five gears are identical and you gain a 6th gear.

Only the 2.4 has a longer 5 speed box, going to a 6 speed increases the rpm in the first 5 gears by about 10%, and 6th is about 10% shorter than the old 5th.

Final drive is a bit different between alfa 5 and 6 speed boxes... so the first 5 gears are a bit shorter on a 6 speed box compared to 5.

Just found this movie of a 147 GTA:

Alfa Romeo 147 GTA 0-200kmh acceleration - YouTube

Looks like it's not as fast (100-160 kph) as your Punto, so well done Vic_O_O !

Yep!

I think currently runing about 210-215hp, this punto is more faster than GTA whit the same power:

Next week new remap and new logs (showing real inyection values)

Untill you need to brake or go round a corner. You will also be missing out on the sound that the V6 makes.

But 200hp out of a GPunto is a nice figure.
