Running similar tests with either the AEM or Apex-i solenoids this weekend.

what freq did you run the profec spec2 solenoid atairshifter wrote:solenoid type- Normally closed
50% = 15
60% = 18
70% = 21
75% = 25.5
78% = 28
80% = 31
87% = 34 (full pull duty cycle)
this car has twin tial 44mm gates and made 13psi when duty cycle was 40% or less, and boost was holding within .5 psi for the pulls untill we got above 30 psi(we ran out of turbo)
