What supporting modifications does the Whipple require? - Technically, none, however a stock or close to stock car would not properly utilize the added efficiency of the larger supercharger.

What kind of gains can be expected from installing a Whipple on my car?
This is where the true power of the Whipple is shown. On a stock car using just a Whipple kit Animul Performance was able to pull out a 13.3 second quarter mile pass. It's important to note that the average stock GTP does a ~14.5 - 14.8 quarter mile pass. This is over a full second improvement in ET with just the Whipple supercharger, on the old style Whipple supercharger no less! While we never recommend running a Whipple on a stock car, this shows the true potential of this supercharger. Results will be exponentially more impressive on modified cars.
