NP, we all learned this info sometime through reading or asking questions.
Here is some basic information. If you apply a BOS setup to your SHO,
expect to go from about 220HP to about 250HP. Throw a 3.2L in and you'll
get another 10HP, so about 260HP. To get these numbers you need to
increase the airflow into the engine by using a larger properly calibrated
MAF. I'm not a drag racer so I can't tell you how this affects times.
Cheers,
