I stand corrected
The Buick Grand National and GNX's History, Told by its Creators
The back story of how Buick's landmark 1980s muscle cars happened, straight from the horsepower makers' mouths.www.caranddriver.com
From the article:
"The next significant improvement was in 1986, when Ron Yuille and the Turbo Engine Group engineered an intercooler for the 3.8 Turbo SFI V-6," wrote Martyn L. Schorr in his book, Buick GNX. With a new two-piece aluminum intake manifold that increased airflow by 10 percent, the engine was rated at 235 horsepower and 330 lb-ft of torque for '86, then 245 horsepower and 355 lb-ft for '87.
. Must be why I got my 87 GN off the original owner in '95 and still have (but obviously forgot the HP differences, lol) rather than an 86. Have a great day.
