What kind of car was the 1989 Pontiac Trans Am?
And so, it was rather a big deal that, other than lights, safety gear and radios, and yanking the A/C compressor, Pontiac’s 1989 Turbo Trans Am was said to be the first Indy Pace Car in the history of Indy Pace Cars that did not require any mechanical modifications to lead the field.
What’s the 0 to 60 time on a Pontiac Trans Am?
Zero-to-60 times in the 5-second range (Car and Driver posted a 4.6-second 0-60) and low-14-/high-13-second quarter-mile times were common in period road tests. Turbo Buicks had a 124-MPH speed cutoff in order to stay within the rating of their Eagle GT tires.
What kind of exhaust pipe does a Pontiac Trans Am have?
A pair of short-runner, equal-length stainless-steel headers handles the exhaust; the old Buick block’s twitching was band-aided with flex couplings between the headers and 21⁄2-inch exhaust pipes. A traditional Trans Am crossflow muffler crowned with stainless exhaust tips completes the exhaust.
Why was EGT important to the Pontiac Trans Am?
Pontiac discovered that exhaust-gas temps (EGT) were a key to reliability, with fuel-flow management–bigger injectors and fuel pump, primarily–used as a means to control EGT.
