It revs UP quicker and DOWN quicker. I spend a lot of time with my left leg stretched out pressing the clutch to the floor and just coasting. I accellerate up to about 5 MPH over the speed limit when I do this. I'm going to have to document the gas savings a Viper gets by just coasting and then ask for my $3,000 gas guzzler tax back. When it's time to re-engage the clutch very little gas is needed to get back up to the correct RPM of the gear I'm going to be in. Ease the clutch to full engagement and take it easy with the snake pedal and accellerate smoothly.
If I'm real easy in engaging the clutch I can go forward in first gear up a slight incline on my driveway at idle. Reverse in idle has always been with the clutch partially slipping since I go backwards for only very short distances. I haven't tried cruising at idle in first in parking lots yet, though.
Bear in mind after 35+ years of driving this is my first manual shift car and I'm still learning how to be the expert people expect the driver of a Viper to be. This is also my first Viper. Also bear in mind that I have some "neccessary" mods - smooth tubes with S&B filters, Belanger Headers, Random Tech Ultra High Flow Cats, and a Corsa 3" Cat Back with 4" Tips which probably gives me different power over stock Vipers at the extreme low end.
