why do honda engines make so much more power with less boost

i'm just curious to ask this question
why do honda engines make so much more power with less boost. you can built a low compression b seris motor like 8.5-9 to 1 compression about the same compression an the 4g63, but they always make mosr power with less boost. i mean with a 9.1 compression b seris you only need like 12 psi to break 400+whp on a gt35 or simmular size turbo.
also why can evos run so much more boost on pump gas?. evos always run like 20-23psi on pump gas and built low compression hondas always run like 12-14psi max on pump gas. why can we eovs run 22+ psi on the 8.5 compression and hondas run less than 1 bar on 8.5 compression

Because most hondas have a higher compression ratio......

Some dude i just met over the weekend runs 30 psi daily with a gt35r on straight pump gas in his GSR...

ready, set, KAAAAAAAAABOOOOMMMMMMMMMM.

unless his compression ration is like 7:1 in which it the car wouldnt run idle or even start for that matter. or he is running meth?

Dont believe what the honda nerds tell you, it's all lies. Extremely hard to make 400hp at the front wheels on pump for a honda. Every one of those honda junkies have some BS up their sleeve, and they will NEVER tell you exactly what they run. When someone tells you they run a certain compression ratio, ask them to prove it. On normal motors, I'm pretty sure every psi of boost = 10hp, so do the math, the honda dorks are lying to you.

I always noticed that they have good horsepower but the torque is weak, usually like 100 less then the HP output, on a 400whp car.

i'm talking about built low compression hondas. with the same low 8.5 compression like the evo.

why can we strap on a gt35r and boost 22psi and make 400whp on 91 octane

they can have a gt35r and make 400whp on 12-14psi 91 octane

both assuming they are running the max allowed boost for 91 octane

They probably aren't loosing near as much power through the drivetrain like on an Evo or AWD DSM. So they read higher when dynoed maybe?

i am cominbg from the honda world. i own a 500whp integra and now also have an evo.

and let me tell you that you are worng
built honda motors can make 400whp very very eaisly. much easyer than evo motors even if you take into the account of drive train lost from awd they are still making more power easyer.. espically at much lower boost levers with the same low compression ratios as the evo. i am just asking why?

and you are so wrong about 1 psi = 10 hp. that make be true for the stock evo turbo on evos. but not with bigger turbos. with bot evos and espically hondas a large gt35r size turbo can be more than 20 whp per bound of boost. a stock evo turbo make make 300whp with 20 psi but will make about 400whp on 20 psi with a gt35r sized turbo

No meth. I thought the same thing, he gave the indication that he knew it wasn't smart though...

even if you go past the more awd drivetrain lost they are still making way more power per pound of boost at the same compression ratios as evos.
i'm just asking why

just about everycar that doesn't come stock with a turbo runs low boost.

dont understnad why either.. i have a friend with a camaro running 7 pounds. i think he picked up more than 100whp at that low of boost.

and another friend with a turbo mustang running 11 pounds and picked up massive massive hp as well

cheers!
