1991 Pontiac Firebird Formula - Dyno Diagnosis, TPI Style
|
Stock initial ignition timing on a TPI 350 is 6 degrees BTDC, and that's where the Firebird was when we checked it, though it had been retarded to that point to accommodate nitrous. Charting the advance curve on computer-controlled cars is difficult, since many won't advance properly in Neutral. Instead, we made another pull while Tom Habrzyk kept the dial-back light on the timing tab. With 6 degrees initial, total timing seemed to be 34 degrees, a bit aggressive for nitrous pulls. Good thing we checked...after running the juice. View Related Article
