i just want to no how much hp i will gain since the extractor comes from a mivec 4g92

if ur expecting an increase.. expect a max of 10whp on a dynojet. if u get more than ur lucky...

but since this is a rojak case... be prepared to actually lose power as well... so do a before and after run for proper comparison.

why will i loose power

 

[wajunk]

maybe lose ur low or high end torque..
but increase either one..
just my 2 cents.

why will i loose power

u may lose power bkos the header was designed for a different engine with different characteristics

just a header I dont think it will make any difference thought? what about a proper exhaust system?

 

[D7zul]

only a dyno test can confirm an increase/decrease in ur hp
