Have had 3 different kinds of Porsches.
944 Turbo, BoxsterS, and 928GT'
These three cars with their different weights and peak HP amazingly enough had the same 0-60 times, 5.4 seconds. But that 0-60 time felt very different in each car.
The 951's hp curve starts low and increased significantly as rpm increased.
This made the 951 accelerate faster as you increased rpm. It kept pushing you back in the seat harder as rpm increased. Making it feel the fastest.
The Boxster started out higher in hp, but did not increase as much as the Turbo as rpm increased. As rpm increase you got used to the acceleration rate and while it felt faster as rpm increased it did not keep pushing you back into the seat as rpm increased.
The 928 hp curve, due to the dual plenum intake is almost perfectly flat. It has more power at low rpms, but does not increase much as rpms increase. The acceleration rate stays the same from low rpm thru high rpm. Once you change gears because the acceleration rate stays the same it feels like it accelerates slower as the rpms increase. Making it FEEL the slowest of the three even though their 0-60 times are the same.
The upgrades I made to the GTS each increased the power band, cams, headers, x-pipe, tuning. They were not peak or low-end, but raised the entire curve. While not getting the crazy peak hp of cars like the Hellcat, It increase the low end enough to make it a bit touchy on initial acceleration. That is why I mentioned when accelerating from 0 to over 25. Like when merging from a stop to 45mph traffic. Below 25 you can eaily accelerate without crossing too much into the power curve. I'm sure that going to injectors that are a little bigger will help smooth out that instant on transition.
