Fast Intake Port - Anyone?

[Filipe_500]

Hi all!

I would like to know if any of u guys know something about Fast intake porting!

I took my GS500 head to get some work done by my mechanics, and he sugested to enlarge the ports, but after i read this article (topic 16 to 20)
http://mototuneusa.com/thanx.htm,


I´ve spoke with him and he found it interesting and he said that he could try to do something like it.

What u guys think? should I enlarge the ports, or should I try this Fast intake ports?

Anyone here hav tryied it b4?


Thx

try making them fast first, less you need to add, the if it doesnt work, you can go large.

Read "Scientific Design of Exhaust and Intake Systems"

by Philip H. Smith
with John C. Morrison

You can't just "restrict" the intake port and assume that it will perform as advertised.  At the same time, widening and polishing them isn't necessarily the best.  There is a happy medium. 

Read the book before you go at it with a die grinder.  It has a section on optimum exhaust port velocity.

damn, you went a ruined it. i wanted to see the pictures of a dude augering out the ports and him coming back and asking why the engine didnt start or even run very well. THEN we could have asked how his knowledge in Intake and exhaust Dynamics.

I just find it funny how people are so willing to go at their rides with die grinders, torches, and big wrenches.  Yet a scratch on the gas tank is the end of the world.

Cliffs notes version for those of us with ADD plz... Are they talking about porting and polishing or something else?
