Parity Adjustments Factory Stock Showdown

[Rat Raceway]

The DP car have the least efficient blowers of the group! No one to blame but themselves.

The older 2.9 Whipple is a heat pump in comparison to the Whipple on the Cobra Jet cars, their 3.0L duel inter cooler is much better. The COPO are much smaller at 2.65L but it’s a roots style. (More efficient air pump)


I seriously think they should all have run the same blowers like it was at the start of the class. Then adjust pulley size and weight to make the parity truly work. If they would have just made pulley changes last year like this year it would have been a way different game.
