5 italian tuners.
That's a valid example on how to evalute power delivery compared to the power peak.
Crispi74 1y ago @196ss
Ok I see.
I posted these scans because we found in past so many similar situations were the power delivery affect chrono more than how really the high top power do.
I suggest to try to translate the article.
It's interesting to read that the "Orlando" Sierra was the powerful car because they used +300 PS road power kit + harder cams profile and turbo but this doesn't affect acceleration like the "Vaccari" Sierra that produce better low power basically with just a 270 PS well ECU map tune.
This is just to say how Marelli IAW was functional using the ability of overboosting.
That example is very helpful imo.

Thanks for the article, that's very interesting topic indeed.
Curiously, that Orlando, while accelerating from a standstill about as fast as BMC and Vaccari and having an even higher top speed, seems weaker when accelerating in gear. It would be very interesting to see the torque curves of these tuned engines. Won't be surprised if Orlando motor is tuned more for top end power than low end torque.
In general, from what I've seen, we have to be careful with hp numbers claimed by tuners. It often happens that a car with less claimed power goes faster. Probably it can be explained by different conditions and approaches to the power measurement.
