Headers with a supercharger
I'm thinking about getting a set of headers for my '97. But $1000 for a 10 horsepower gain doesn't seem worth it. Since my car is supercharged and making over 500 horsepower at the crank already, will there be a gain from them? I'm thinking long tubes would benefit me more then regular length, but honestly, will it be worth the money? Also, what would be a good brand to go with? Thanks!

Re: Headers with a supercharger (QuickSilver97)
I'm sure you would realize a gain because you could get more air out of the engine faster. This mod might cause you to have to reprogram the computer, considering the supercharger and all: something to think about. Maybe Carroll can give you come insight or the other guys on the forum who have supercharged cars. Sharp car....

Re: Headers with a supercharger (QuickSilver97)
You'll gain more than most with headers. All forced induction engines love zero backpressure, more so with turbo cars. You may need a smaller supercharger pulley though, when you free up the exhaust, you lose boost because your engine is running more efficiently.
On my Regal, right now I'm running 12# of boost, but when I remove my muffler it drops down to 10#. Even though I see 2 less #'s of boost, the engine runs stronger. I see more advance, and less knock retard because the same amount of air is flowing through the engine, it's just not heated up as much. Plus when I remove my mufler, I can change my pulley and bring the boost back up to 12# for even more power. I usually only do that with 100 octane though.
Good Luck,

Re: Headers with a supercharger (BLOWNGS)
Thanks guys! I'll give Carroll a call tomorrow and get his opinion. I hadn't thought about needing a reprogram and truthfully don't know if I want to get that involved for a mere 15 or 20 more horsepower. Who knows though, maybe it would be worth it.
