There are a few things that can cause that.

What oil are you using?

a b/t 20v is 1.6 l right?

so its flow is....CFM =( L x rpm x VE x Pr) / 5660


CFM = (1.6 x 8000 x 100% x 1) / 5660

CFM = 226.15

use the caluclator on this page to get HP rating for that air flow dont mind its a turbo calculator

scroll up and put in 226 in the cfm box and click calculate 8-)


u get 150.77 hp :P

and thats using 8000 rpm and 100% ve eh :|

the only way to get more air flow is: to rev higher , change VE, incerease displacement or raise Pr (forced induction)
