2005 Pontiac GTO Header Install - Bellowing Goat
|
We put the Goat back on the Dynojet's rollers for another round of pulls. To our surprise, we gained 19 rwhp and 24 lb-ft of torque without any tuning. Greg made some minor adjustments to the tune and was able to free up six additional ponies, but torque fell off a bit when timing was added. Thanks to the poor intake system on the late-model GTOs, inlet air temperatures soared. We read more than 110 degrees on every pull. This greatly limited how much timing could be added. Run 1 was our baseline, Run 4 was after the headers, and Run 13 was after the tune. To ensure accuracy, each pull was supported by additional runs. View Related Article
