I wonder how amhp (aftermarket horse power) compares to bhp and whp. I’m guessing:
bhp<whp<<<<<<<<<<<<<<<<<<<<<amhp :headbang:

i think AMHP is a combination of what your car made stock bhp from the factory with the full autozone claimed gain from your mods. i’m having trouble conveying what i want to say. i’ll use an example with my integra. i wanna say they made 130 bhp from the factory. i don’t know for sure, but this is all hypothetical.
130 bhp means i make around 130 hp…drivetrain loss is a myth of advanced automotive theory in this mindset.
i went to pep boys and bought an intake. on the sticker they claimed up to a 15% gain in hp.
130 hp + 15% (19.5 hp) = 149.5
we’ll round up because my install was done really well.
i now have 150 hp.
i have enough money left over from my paycheck for a new muffler. the muffler sticker said i would get a 5-10% gain from this in hp. they are on sale and i’ll get better gas milage according to the sticker, so it’s worth it. i’m a good driver and i’ll put the muffler on really well. we’ll assume it’s a 10% gain.
150 hp + 10% (15 hp) = 165 hp.
my friend told me people talk about cars on the internet. apparently they can do stuff to the computer in the car to make it even faster. as long as we’re on the internet, might as well check ebay. oh look…capacitors.
upgraded ECU’s make as much as 30% more power. now that’s what i’m talking about.
165 + 30% (49.5 hp) = 214.5 hp
obligatory round up brings us to around 215 amhp.
we haven’t even turbo’d the shit out of it yet.
make more sense?
