I'm planning a modest upgrade for my street-legal drag car and I'm torn between adding a turbo/supercharger or sticking with a naturally aspirated engine. Generally, how do forced induction systems affect torque curves, reliability, and overall cost compared to a NA build? Also, what are the typical compromises in weight and drivetrain stress? Looking for thoughts on the practical trade-offs and any tips for balancing power and durability.
Are forced induction setups better than naturally aspirated ones for drag racing performance?

Yep, bro, when I added a turbo, the torque curve just spikes at low RPMs, but if you don’t nail the boost control, it puts way more stress on the engine and transmission. Superchargers give instant pull, but they add weight and kill fuel economy. If your budget’s tight, I’d say stick with a naturally aspirated setup, upgrade to a lightweight clutch and aluminum flywheel, and keep things reliable. But if you’re chasing big power, you gotta dial in the turbo’s boost right and beef up the drivetrain.
