Why I will never go back to a 2.0L
Its no secret that I prefer large motors and turbos together. Every 2.0L I have driven, including mine with the 3586, was never as much as fun as it has been with the 2.2 and 2.4L. When you have the 4k rpm powerband not start until 5k its amazing how differently you have to drive the car for it to "feel" right. I had to stay a gear lower when I needed to pass, it seemed I would drive around town at 3500 or so to keep it fun, just not what I wanted.
So in 2009 I switched to a 2.2 and it was good. It picked up better than the 2.0L but it still lacked some of what I had hoped for with the larger motor. It was about halfway between a 2.0L and a 2.4L (2235cc) but it really still seemed to favor the 2.0L side of the family. It was 400rpm faster but that wasnt enough, then came the LR2.4 and I finally had found what I wanted.
My 3586 made 21psi at 4200 now (vs 4900 for the 2.0L), I could drive it like I stole it and it felt more like a 2.0L and FPBlack to me than ever. We have been building 2.4s regularly since. Today I tuned a newly born LR2.4 and the difference from the 2.0L to LR2.4 is intense-
Spool is a minimum of 550rpm faster, reaching 24.8psi at 4186rpm vs 4729 on the 2.0L. There is 100 ft lbs more everywhere under 6k now and 140 ft lbs more at 4500. For a pure street car a big motor is the right answer. Gear it right and the 2.4 isnt even a bad choice for more aggressive usage.

So I got a brilliant idea and decided that since the pulls are the same gear I would show the difference in time it takes to spool and make the pull, the extra response from the 2.4 is not surprising to me but may be to some. You will notice there was about a 1sec delay from the time the pull started until it was really at 100% TPS.
Its about 2 seconds difference.
