I did a bunch more porting today and used some of Gregs suggestions on having sharper edges. Intake is noticably louder now.

 

when i modded the tb on my gsl-se it ported the **** out of it, i never noticed a louder intake, with the afm you cant even hear the intake on rotaries. its lame.

not calling bs on your louder intake comments, but im going from my experiences

 

ya the afm makes **** hella quite

 

I only noticed because of how it sounded with the hood up when i was adjusting the idle. Going down the road I haven't noticed a difference, only when the hood is up.

 

yeah my new gsl-se when it idles i can hear the ssssssssss of the intake, but the exhaust overtakes the intake above idle

 

whatever trever....
