Supercharges produce the greatest amount of bolt-on HP today. Understanding that you’re working on your daily driver I would recommend going with a “low” boost for what you driving condition allow.
I would expect around 30% increase in power for a moderate level of boost.
Forced induction has always been a good method of producing more HP but just as most other modifications it will definitely take it’s toll on the longevity of your engine. I would keep it around 6-8 lbs max and I would have it installed by someone with experience. You’ll be able to sleep at night knowing that your car will start in the morning……
Let us know what you decide.
