difference between HP & BHP (horsepower)?
958842
Horsepower is defined as work done over time. The exact definition of one horsepower is 33,000 lb.ft./minute. Put another way, if you were to lift 33,000 pounds one foot over a period of one minute, you would have been working at the rate of one horsepower. In this case, you'd have expended one horsepower-minute of energy. \n\nBrake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump and other auxiliaries. Thus the prefix "brake" refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less.

They are not proportional.  Watts are units of power, volts are not.  Similarly, you can't ask "how many kilometres per hour are in a kilogram?"\n\nIn direct current conditions, the power expended in a device (in Watts) is equal to the voltage across the device (in Volts) times the current passing through the device (in Amperes).

You should size the turbos based on your horsepower goal:\n\nA turbo helps support about 1 horsepower per 1.345 cfm airflow (that the turbo is rated at). Take the cfm rating of the turbo you are considering and multiply by two (to get the total cfm provided by the two turbos).\n\n\n----\n\nWhat I referred to was the cfm ratings of the turbos themselves. Those are usually specified by the turbo manufacturer in the form of a compressor map. The 1.345 figure I gave is the most commonly quoted estimated. For example, if you wanted a 250hp car, you would need one or more turbos rated a combined 336 cfm.\n\nAnother factor is making sure you have enough exhaust flow to spool the turbos quickly. In other words, don't oversize the turbos or the turbo response will not happen until a high rpm, thus reducing drivability somewhat.

Is it a gas or a Diesel?  Thie easiest way to think about HP. is this:  You need either air to go faster into the engine...or faster out of the engine.  Easy inexpensive fixes could be a cold air intake or a throttle body spacer.  These would allow air to enter your engine faster.  Another option is a more free flowing exhaust...sucking air out faster.  If you want to spend more money..a computer chip or programmer (you have to run premium gas if you have a gas vehicle)..or supercharger or turbo.  These are more expensive than the options above

they really need to keep kids from answering questions, since the previous dipsh!t has no idea what he is talking about.\n\nan intake manifolds rpm range refers to what rpms that particular manifold is best suited to make power at. i.e. a dual plane intake is generally good from idle til 5500-7000 rpm, a tunnel ram is in the 3500-8000+ rpm range.\n\nbut to answer your question, you either have an older manifold or you have your second number incorrect, is it possibly a 36 instead of a 35?

One "Bar" of boost is equal to one atmosphere of pressure at sea level (or 14.7 pounds). Boost was used of course because as piston engines gain altitude (less dense air) they loose horsepower. Originally with aircraft the idea was to just maintain the horsepower that the engine had at sea level. It was quickly learned however that an engines output could be greatly increased with both turbo charger and super charger technology.\nBoost technology can best be defined by the development over several years of just one car, the Porsche 917. First built in 1969 the normally aspirated 12 cylinder engine was about 650 HP, in 1972 the turbocharged 917-10k had 850 HP, and in 1973 the intercooled turbocharged 917-30 would produce 1,500 HP with qualifying trim boost, or nearly double what it was without boost.

British horsepower is also known as just horsepower.\nOne horsepower = 745.7 watts\nSee the howstuffworks link for an interesting look at horsepower.\n\nTo find the rated electrical input power required for a motor knowing the horsepower:\nkVA = (hp*.7457)/(eff*pf)\n\nwhere kVA = rated input power in kilo volt-amps\nhp = rated output horsepower\neff = motor efficiency (Pout/Pin)\npf = power factor of the motor\n\nIn general, a generator can take a load that is equivalent to the input power times the generator efficiency.  After all, a generator just converts energy from a mechanical form to electrical form with some losses in the process.  I admit that it isn't quite as simple as that, though, so I recommend further reading.\n\nTry Wikipedia, howstuffworks, etc for a start with general reading.  Those should lead to the more in-depth stuff.

Probably around 15-25 hp.

Ok, so you have two simple equations to keep in mind:\n\n1)  KE = (1/2)*m*v^2\n(kinetic energy equals one half mass times velocity squared)\n\n2) Paverage = E/t\n(average power equals energy divided by time)\n\nFirst you find the kinetic energy (convert that km/hr speed into m/s).  Now you have the kinetic energy for the car after the acceleration period (in Joules) which can then be divided by the time to get the average power (in J/s or Watts) required to get that car up to the given speed.\n\nThen we sometimes like to convert mechanical power from Watts into horsepower.  The conversion happens to be 745.7 W/hp.\n\nI will leave the calculations up to you, but those are the equations/concepts you need to know and apply.  Also, take note that this is an idealized solution that does not take into account wind resistance, rolling friction and various other factors that would require more power output from the engine of the vehicle.

EHP what the 99 is rated, BHP you gotta do the math on that

Turbo is a good way to increase your car's power. Also, a bigger intercooler as well as new piping kit will help moter breath better. A new air filter will give you some extra power. A good exhaust and a new ECU program will help you a lot. After these your power must be 500+ PS, believe it or not. I have seen M3 over 1000 PS.

you won't notice a difference with 5 hp gain, you want top end or bottom end speed, i suggest changing rear end gears for big torque gains, can make a little 4.6 boil those tires but not mess with factory engine components that are set for optimal engine life. e-mail me for  furhter help, jsconyers6401@charter.net

It would help to know the year model and any other model specific info.\n\nHowever, the 352 looks to have been used in the 1950s-1960s, and maybe up into the 70s.\n\nIts horsepower ranged from 208 hp (2bbl carb) to 300hp (4bbl cop). Beware that these are GROSS horsepower numbers, as opposed to NET horsepower which has been reported since the 70s.

First, know what your talking about. How can you have "turbo" headers if your running on motor? Turbo headers is known as a turbo manifold, which sends the ehaust to the turbine. \n\nAre you looking to go all motor or boost?

1 kilowatt = 1.34102209 horsepower\n\nIf you want to convert anything, go to http://www.google.com/. Type in, for example, "convert 20 kilowatts to horsepower" and Google will do the conversion for you.

power to weight ratio = power/weight.\n\nIn quoting it, you must give the units, e.g.\nhorsepower per ton, watts per pound, kilowatts per kilogram...

Headers decrease back-pressure which increases horsepower.  Dual exhause allows for free flowing exhause - to increase horsepower.  One thing with more modern cars, you would need to add a second o2 sensor (some v6 or v8 cars have a single o2 sensor at the end of the crossover pipe).  Dual tail pipes is way more common than genuine dual exhause - you do need two of everything (o2 sensors, cats, ect).
