So do you think a supercharged gen III is slower than a gen IV n/a to 60 mph?
It depends on how the cars are equipped and the driver. If the Paxtonized Gen III has the stock run flats and the Gen IV is stock, the Gen IV, because of the much improved shifting, the improved differential, the fact that it does not have to be shifted before sixty, and the PS2's will achieve a fast 0 to 60 time with less driver skill input required than an equivalent run with the Paxtonized Gen III with run flats and the older tranny, shifter and differential. However, assuming the driver has practiced rolling into the throttle with a Paxtonized Gen III and is skillful with the old tranny and shifter, a faster 0 to 60 time is possible.
My '06 had run flats and stock '06 tranny ( the shifter springs were tightened up a bit ) and differential prior to the end of this January. In January I had an '08 tranny, yolk, driveshaft, differential, and PS2's put on the car. I also had a prototype ( at that time ) MGW shifting mechanism put in. With alot of practice and concentration I could do 0 to 60 runs pretty well with the car the way it was. Now, it is much easier. I can shift with complete confidence and the traction is much better. I also have Racelogic traction control but I have set it so that it really does not come into play with respect to this issue. It can be set with slippage from 0 to 25%. It can also be completely turned off. It has a launch function but i do not use it.
I recently had the opprtunity to drive the '08 at the SRT Track experience. On the cone course they set up they let me stay in first a bit more because I was an experienced Viper driver. I was able to throw the rear end around a teensy bit before the ride along told me to stop it. The bottom line: my car is much faster than an '08. And, since I am used to 743 HP, the '08 seemed tame.
