Decided on the Livernois S975 package plus their CAT delete pipes and oil catch can, already had a JLT CAI and 180F thermostat. Got pricing for “mail order” do it myself and “turn-key” shipping it to them…..decided on the do it myself option. Installed CAT delete pipes, spark plugs, fuel injectors, supercharger pulley, balancer pulley and oil catch can. Had to ship engine PCM to Livernois and then had to wait in line for the Trans tune laptop.
Note - Timers are from the Performance Page.
(BeforePerformance Benchmark)
Before any of the 975 package install I benchmarked the performance at DA 425’ (JLT CAI and 180F thermostat were already installed) using the performance pages and timers.
Timers; 60’=1.48, 0-60=3.1, 0-100=8.0, 1/8et=7.3, 1/8mph=94, 1/4et=11.5, 1/4mph=118.
Per wallace racing calculators and using 5600 lbs the 1/8et=7.3 is 711hp, 1/8mph=94 is 723hp, 1/4et=11.5 is 728hp and 1/4mph=118 is 709hp, all the hp average to 718 hp at DA 425’ = Correction 1.0292.
DA Corrected Horsepower = 739.
(Initial After Performance Benchmark)
Timers;60’=1.36, 0-60=2.7, 0-100=6.3, 1/8et=6.8, 1/8mph=102, 1/4et=10.7, 1/4mph=127.
Per wallace racing calculators and using 5600 lbs the 1/8et=6.8 is 880hp, 1/8mph=102 is 924hp, 1/4et=10.7 is 903hp and 1/4mph=127 is 883hp, all the hp average to 898 hp at DA 2,091’ or Correction 1.0553.
DA Corrected Horsepower = 948.
Horsepower Increase = 209 which is right in line with Livernois advertisement of 220.
Using a pie tape on the pulleys;
Upper pulley went from 3.365” dia to 3.055” dia = 10% speed increase, and
Lower pulley went from 8.015” dia to 8.760” dia = 9% speed increase,
For a total of 19% supercharger speed increase…..the accessary pulley virtually remained the same.
