With ya now. :wink: Just make sure the boost retard solenoid will pull enough timing out, vac advance solenoids only add around 8*, you'll need more retarding than that.
FYI - I actually went slower with a T28 running 18 odd psi (15.3'ish) than a T25G running 10psi (14.5), so its not all down to volume like Darren said. Responsiveness and where it makes the power makes all the difference on the strip. :yes:
Oh and BTW, I'm pretty sure 7ke's have CAS's, but still have a dizzy cap for spark distro duties. Maybe look into them. I've actually got a K series hall effects CAS (custom) at home I need to fit, but need 3x more coils and ignitors to use it.
