The examples being lets say BMW E46 M3 and the new BMW G80 M3. The E46 has a 3.2 i6 NA that makes 338hp, the G80 M3 has a 3.0 i6 twin turbo that makes 510hp.
What technological advancements have been made, other than the turbos and 20 years, that separate these 2 cars?
If you know something really technical feel free to share.
Yeah, all of this.
I used to have a Skyline with a built RB25, made 450-500hp, and beyond that it was either too laggy or too peaky. Just using a modern turbo and E85, it’d be just as drivable and make 550-600hp now, quite easily.
Nowadays, my stock M3 makes 450bhp, and with not much work will make 550bhp… times have changed
