The rev hang is on purpose for emissions reasons. They have been doing this to cars since the 1970's. A tuner can program that out of the mix.For some reason I could not type in my OP without losing the pop up keyboard on iPhone 5 ... Mods should look into this.
Anyways, i was thinkig about how the FiST sounds when revving the engine. I suspect that either the ST has a heavy crank and/or flywheel, or the boost blows by in the cylinders through the valve overlap. I'm not sure if anyone follows me, but have't anyone noticed how "uneagerly" the revs drop off while revving the engine at idle? Its almost like it resembles the R32 sound (VW R32 with 3.2L V6). The revs jump up fast, yet stay up and don't fall off as quickly.
Have any of the tuning companies looked into this?
By lightning the crank and/or flywheel, I suspect more throttle response and minimal hp can be gained.
The downside would be unless you shift very quickly, you would drop out of boost.
Let me know what you guys think.
With Hill Assist, that last part is much less a concern.I had a turbo Subaru with a lot of mods, one of them was a billet flywheel that was about half the weight of the stock flywheel . It made a noticeable difference to the way the vehicle accelerated and responded to throttle inputs and increased horse power. The negative aspects were it would stall easier and was harder to get off the mark on a hill or with a car load of people, especially both and care had to be taken not to smoke up the clutch in those situations.
