1997 Chevrolet Corvette

Great question! For your 1997 C5 Corvette with the LS1 V8, here are the most common and effective performance upgrades:

Bolt-On Upgrades (Best Bang for Buck):

• Cold Air Intake: +12-15 hp, $300-500 - Easy first mod
• Long Tube Headers: +20-25 hp, $800-1200 - Biggest NA gain
• Cat-Back Exhaust: +8-12 hp, $500-900 - Better sound + power
• ECU Tune: +10-15 hp, $300-600 - Optimizes everything

More Aggressive:

• Performance Camshaft: +40-60 hp, $400-800 - Changes engine character
• Ported Throttle Body: +5-8 hp, $200-400 - Better airflow

Forced Induction:

• Supercharger Kit: +120-180 hp, $5000-8000 - Massive power, but expensive

With just bolt-ons (intake, headers, exhaust, tune), you’ll see about 85-125 hp gain, putting you around 430-470 hp at the crank. The LS1 responds very well to these basic mods!
