Whats the reason behind dumping supercharged engine?
Obviously a car with individual throttle bodies will respond quicker, with almost a hair-trigger like TR. Some cars have a sport button which different programs for how quickly the throttle bodies open. RS4 is one of them as well.
But I feel a car with a lighter drivetrain, has less mass to rotate & will spring open the throttle quicker than a car with a beefier drivetrain. Does that make sense now?

I know all of these. Shall I share them with my friends?
Troll elsewhere, or be prepared.

I'm on my laptop now, the boomkark is on the PC.
Stay tuned...

If it's public information that can be obtained by anyone here, then it's fair game. Sorry for any misunderstanding.
Rock: I'm not meaning to be a killjoy, but if you had some information that wasn't public, would you want people to share it?
Grumpy, that is one of the funniest posts I've read on here
How does the mass of the car affect how quickly the throttle opens?

Should get three results; click on the one from the RS6 forum, or the cached version of the other two.
There's this one too, by a different dude:

What an idiot....look at all of the posts he changed to ".". Clearly, he was scared ****less, but when I point it out here he starts with the name calling and chest thumping. Fine...have it your way, M&M.

Ohh then we have post #4 and it goes down hill from there.

I've been reading this thread and understand your point. I think however that there is more than just TR that you are describing. Throttle sensitivity maybe be a better description.
In the M3 there's a switch that changes the amount of TR compared to the input made by your foot. I put this on whenever I drive it. The default setting stinks.
My Vette used to be a bit sluggish in regard to quick revs until I put a less restrictive intake (lingenfelter) and a light weight (30#) single mass flywheel. Revs come right now compared to stock. My Vette's TR is so much quicker than the current C5s that they feel like snails even tho the performance numbers aren't that much difference.
As far a whether or not TR is quicker in a NA car vs FI I think all factors have to be equal, ie.....check the difference between a E500 and an E55. I think that you will see that the only difference is the time delay of the SC clutch engagement. This makes it a bit less controllable in a track situation but certainly the gains of the SC are worth it. Smoothness of the throttle to engine response IMO is definitely better in the E500 compared to the E55.
Just my 2c.
You feel it in sport mode where the throttle butterflies open up instantly you prod the throttle. My wife turns it off when she drives 'cos she says she might back up into the wall

I drove a modd'd S2000 once it was even more sensitive.
