THE LIST
Created by: Matt
These modifications are only the most common and reliable modifications. There are others out there, however.
All of the approximate horsepower gains are based on a 100% stock motor. Gains will be reduced when more modifications have been done to your engine (that means you simply can't add horsepower figures).
Prices are also approximate, and are based on what I have personally seen or been told about.
** in front of the modification indicates a possible increase in gas mileage.
Horsepower Gains
Substantial Gains (Greater than 50 hp): Typically very expensive and require good working knowledge of your engine and custom modification and involved hands on work.
Supercharger................System Dependent Hp......................System Dependent Cost
Turbocharger................System Dependent Hp......................System Dependent Cost
Engine Swap................Engine Dependent Hp.......................Engine Dependent Cost
Nitrous.........................35-75 hp w/Stock Internals; 100 hp+ w/aftermarket internals $500-$2000+
New Intake...................Would have to be a custom fabricated unit
Very Good Gains (15-50 hp): Typically same requirements as the Substantial Gains category, and are typically done in preparation for a Substantial Gain Modification or just by themselves.
Custom Computer Programming (if applicable)......
Program and Engine Dependent hp...............................15-30 hp......$250-$600

Bore and Stroke................................
Pistons........................................... ..
Crankshaft.......................................
Good Gains (5-15 hp): This is your typical 'Bolt-on' list where jobs can be completed in an afternoon or weekend. A good deal of these modifications are walked through on the S-10 Planet Tech section.

Venom Computer System (works at part throttle only)..................7-10 hp..........$250-$350
Fuel Pressure Regulator (helps mainly TBI engines).....................?-?? hp..........$75-$150
"Gains" (0-5 hp): More 'Bolt-ons', but ones that simply produce less power
**High Flow Catalytic Converter......................................... .....2-5 hp.............$75-$150
**Full Synthetics (Engine, Transmission, Differentials)..............2-5 hp.............$50-$300
Powerdyne's Throttle Body spacer (non TBI or Carb)............... 3-5hp..............$100

MAF De-screening (96+ years)............................................ ....0-2hp..............FREE
PCV Breather Mod............................................... ..................0-2 hp.............$5-$10
Modifications that Simply Lighten Your Wallet (0 hp or negative hp gains):
IAT modifications bought off of Ebay, "Timing chips" for $1, $5, etc.
Throttle body spacers for non-TBI or carbed engines (basically the newer motors)
Casper TPS-TEC for pre-2001 trucks (works, but could be done for free)
Tornado Air Management System or similar amazing swirly system
Granatelli MAF or Aftermarket mass airflow sensors (w/o a reflash on a stock motor)
Special spark plugs (think Bosch +4)
ZMAX
Electric Superchargers
Extra Ground Wire Kits (won't hurt, but won't help)
Porting and/or removing the center bar in the MAF (negative numbers)
Other modifications to improve acceleration:
Making the Truck Lighter:
**Fiberglass Hoods & Body Parts
**Tubular Control Arms & 4 Links
**Drilled Rotors
Be creative -- Do you really need carpet or a passenger seat at the strip?
Aerodynamics (Help out especially at highway speeds, but help out looks at lower speeds)
**Replace stock mirrors...........................$140
**Tonneau cover......................................$200
**Headlight covers (Sealed beam lights).....$20
**Remove Roof rack if applicable...............FREE
Again, be creative. If something can be improved, go for it!
Transmission Improvement:

Here's another vital fact to remember when modifying your engine. I found this on SLP's website, and I think it will help give a more realistic HP gain.
Question: Can I just add up the advertised horsepower gains from each modification I make? FOR EXAMPLE: 10HP From a cold air intake, 20HP From an exhaust (cat-back) system, and 20HP from a header, for a total of 50 horsepower?
Answer: Simply put, not all HP/Torque gains can be added straight up. Though adding up advertised peak gains from each part is not a bad starting point, use the advertised gains as a target gain, then use some common sense. If it is a complicated issue consult a sales representative. Here's an example: If you install a cold air intake and a cat-back exhaust, you can reasonably add the HP gains, because you are modifying two seperate, yet complimentary parts. If you add a cold air intake, heat shield, and MAS without changing anything else, you will typically get something less than the sum of the peak gains advertised by each part. "Forecasting" or "predicting" peak horsepower gains is an inaccurate science. Do not be discouraged if chassis dyno "peak" numbers are not exactly what you expect. Pay attention to gains anywhere in the torque curve. Low and midrange torque gains are usually much more beneficial and seat-of-the-pants noticable than peak gains alone. The total area under the dyno curve is the horsepower that counts, not spikes or peaks!
