for a very short time. Just my $0.02 worth.
Coyote (wondering where the other $0.98 from that dollar went.)
the supercharger engages/disengages via the ECU based on 3 factors:
1. Load (throttle input)= 40% or greater and the S/C engages(FYI, it doesn't take much to get to 40% load in these cars
)
2. IAT's= 199 degrees or greater and the S/C will disengage (this is how you know the I/C pump is toast)
3. RPM= 3,000rpm (this condition is if the S/C is not already engaged at this point)
Brian, i will run the numbers and post back up, it is a little late and my brain is a little fuzzy right now...
