girl at school has a redline, turned it on all the time with a tech 2. the svt lightning at school is not on all the time from the factory either. the supercharged LSJ's intercooler sucks anyways, by the 3rd pass on the dyno it was completely ineffective, due to its fmhe being only 3/4" thick. i will be doing this when i throw on my 3.0 pulley with my phenolic ic core. im having the solenoid to the switch that controls my pump on/off, when i hit the ic on button, the solenoid will block off boost to the bottom of the bbv diaphragm, giving full boost. when its de energized, it will allow a metered amount of boost to go to the bottom of the diaphragm, keeping boost around 8 psi.
