if you look at the development of all the high-performance engines you will have to remember that all manufacturers are more likely to trim on space and speed than to tickle out the power with turbos…. I wonder why? what is so steep on a turbo? the load of a 6.3l engine at 7200 turns is also enormous… there’s real mass in motion …. still in the 80s every turbos has installed and jets are almost all gone… I can n ciht really at many cars erin you can forget that in the 80’s the group b has experienced a boom and thus a lot of money in the development of motors with small hubram + tubro flow…. today the formula 1 is the flag ship of racing and there, as you know, engines that get their power from the speeds… what do you think about it?
