Headers / free-flowing exhaust is usually at the top of the "bang for the buck list".

Nitrous?

Fastest way to free horsepower.....

is to shed WEIGHT.

Remember the Caddy Hack article that Hot Rod mag did several years back? they figured each 100 pounds shed added a tenth to the ET.

They took a bone-stock Caddy and without touching the motor, got it from 17 seconds in the quarter down to 14's, just by cutting out excess weight.

Lightweight Weld forged wheels not only cut static weight, but also rotational and unsprung weight off the chassis when in motion. Less effort needed to get the wheels turning or changing direction leads to improved acceleration and handling.

Lighter weight parts may also improve efficiency, in the case of an aluminum intake that flows better, or those headers that flow better and weigh less than the stock cast-iron boat anchors.

Fibreglass or carbon fiber body panels look the same and keep the lines of your ride, but at a bigger weight savings than steel parts. Similarly, it's not too hard to duplicate things like inner panels out of aluminum sheet or plastic, and cut weight out.

Another thing that helps is to move heavy items nearer the center of gravity/polar moment. Some things like engine/trans or rear axle would be difficult to do this, other things like a heavy battery, are relatively easy to move nearer the car's center of mass.

And, while doing that, consider a lighter part in place of a heavier one. If you don't need 1000 amps to start that 4-cylinder rat rod you are building, an aftermarket (lighter weight) battery like for a Honda would be ideal. Likewise for big alternators, heavy sub boxes, lots of extra lighting, etc.

Just some ideas...

Nothing in this world comes Cheap!!

HP costs Big $$Bucks$$ and can cause your engine to blow up!! Drop the weight of the vehicle. A new chip for the newer cars. And here is the really big problem, what do you call cheap? What might be cheap to you might not be cheap to me. Or you might pass up a deal on ported and polished heads that I would jump on.
