I would say it all depends on your intake and exhaust system. I run mine with stock headers, nismo duel rai and 60mm invidia n1 exhaust...runs great with stock headers.. remember, just because it is aftermarket does not mean better...
Headers are aftermarket replacements for the exaust manifolds. They are the parts bolted directly to the heads on the sides of the motor. They channel the exaust from each cylinder down to the exaust pipes.
This isn't a very well phrased question as you could mean how much horsepower does adding a turbocharger produce, or you could mean how much horsepower do you get from replacing a factory wastegate on a turbocharger with an aftermarket one. However, neither of those questions can be answered concisely without specifics of the application.
Depends on the engine that is turning 1,000 rpm's. A larger engine develops way more horsepower than a small engine at 1,000 rpm's.
In diesel engines, yes. In gasoline engines, not much.
3 to 8 maybey 10 but not likely
309 bhm
2005 - 287hp
400 hp :}
The exhaust extraction on the S2000 is near optimal, precious little
10hp
0 horsepower.
Too many variables, could be less than 5 hp or more than 50.
depends on the size of the headers and the size of the carb. low end.... 650 carb, small tube headers, you can expect about 275 horsepower
The A/T have about 287hp, and the M/T have about 307.
There are too many variables that determine what hp increase headers will give. Engine size, carbed,f.i.,stock,hi perforforman ce,car weight,the list goes on and on....
It does depend on the engine, but I'd shoot a little higher and say headers will give a good 15-30 hp 3 or 4 hp depending on the engine
adding headers will allow engine to breath better and boost up horsepower but not by much, headers also make you vehicle louder with pipes.
