Therefore the engine wastes a lot of horsepower just to run the blower, and it gets you your 40% but at the expense of God knows how much it took to run the thing. You can replace the cam in your car with a custom one which will give you more power, torque or both. Speaking of fuel, if you're still running a carb on a street car, you're letting gobs of power escape as unburned hydrocarbons instead of maximum horsepower. Boost builds early, so you never have turbo lag. This helps you achieve “bonus” power at the mid to upper end, where you tend to need it. If you've done any of the above mods already, you owe your ride a tune to maximize its power potential. This takes some time so for the first fraction of a second you get nothing… it’s just motor. I encourage you to check out my other car performance hubs and do whatever research you need, to know this stuff inside out. Using the RPM and torque of the motor, it’s possible to estimate the horsepower.

I plan to spend an entire hub on this alone but suffice to say you can change every parameter in the car and easily add 10% or more just from programming alone. How To Calculate Your Horsepower.

Superchargers, turbochargers and nitrous oxide systems are all well-known mods used in cars today but have you ever thought about combining them? The lobes themselves control 4 things simultaneously. Cold air intakes are easy to install, and work too, as average dyno results commonly show a 5- to 10-hp gain without a tune.

Note: Not all exhaust mods are emissions legal.

What energy is it wasting? Now that we’ve gone over all of the textbook stuff, let’s have a little fun and talk about power adders that you can install on your car to begin that never-ending transformation from a car into a ride. The stock air filter is discarded in favour of a higher flowing cone filter. The result is a higher velocity of denser air reaching your engine. If you're doing forced induction, big cam, or other performance improvements above, your fuel demands will increase.

None of the breathing mods are strictly additive. It accomplishes this with larger diameter tubing and by straightening as many bends as possible. For even more sports car grip in the corners, look to sport springs. So to correct this in 1972, the SAE net standard was set to make sure that all engines were measured using Net BHP. If you've seen Fast and the Furious, then you know all the cars have these buttons in them that make the cars go fast!

Depending on your engine, safe might mean only a 50 or 100 horsepower increase. Maybe you should. Those look neat, but that's about it.

There is no single modification that can radically increase your engine's power output and transform your ride like a turbocharger or supercharger. A turbo places a turbine in the way of the exhaust so that the gas has to go through the turbine blades. Maybe if there was a bulldog in the passenger seat, a shotgun in the trunk and you were drinking a beer at the time… (don’t do that). Paolo Cross from Philippines on April 12, 2013: Now I know what people are talking about when they say HP. It feels awesome, but dragsters tend to favour the Roots super.

You keep much of the sound and all of the flow so there’s almost no restriction and the sound is amazing! That number equals one new unit of measure, which Watt called horsepower. Each mod adds a little bit but if you do everything you get quite a big gain. It’s when you force air into the engine instead of letting the engine suck it in. Nitrous oxide or N2O is a molecule carrying 2 nitrogen atoms and 1 oxygen atom.

The industry is rich, and you can buy a ton of mods for your car. While 5 psi might not sound like much, people often forget that it's 1/3 of atmospheric pressure and that the 8 psi they're running on their conventional supers is being partly wasted just to operate the supercharger. Do it yourself tuning requires a tuning module which is a few hundred bucks but it pays for itself with what you can do with it. No questions asked. When you're serious about tuning your hot rod, the factory fuel delivery algorithm isn't going to cut it anymore. Got big performance mod plans for your ride?

Just a mild cam change can result in 30 more horsepower at the wheels, or match it with intake and exhaust mods for a potential increase of over 100 hp. It looks like a snail. See you on the other side! A complete turbo kit starts around $2,500 and can go all the way to $10,000, depending on turbo size, expected boost pressure, specialized coatings, and more.
