I know that one can gain a noticable gain of HP of about 10 HP by polishing and sanding the intake and exhaust ports. I just wanted to know what you guys thought of that. I would like to know if anyone here has attempted this. If they have could you please what sort of tools i'll be needing and any problems they encountered. Thanks

 

Doesn't seem to me that this would add any noticable amount of horsepower. It'd prolly help a bit but I'm pretty sure its not gona add 10 hp. Doesn't seem like its worth the time and/or money.

 

DO IT !!!!!!!! In any combustion engine the better it breaths the better it will run.
By P & P you are allowing the air to flow through with less resistance, which inturn allows your engine to run more effeiciently.

 

It also prevents ionized fuel from sticking to the (dirty) walls of the intake passageways, which again helps boost power and efficiency.

 

if you can do it or get it done for a good price go for it. but dont drop a small fortune on it

 

i might want to get a fuel controller, that will help to after the port and polish.

 

be careful attempting this as a first time porter... be willing to accept the fact that you will prolly attempt to port and polish about 5-10 heads before you really get the hang of it and start to actually increase horsepower...

ive seen too many people go into perfectly good heads with die grinders and make a mess and actually cause a loss in horsepower (dyno proven) because they had no clue as to what they were doing..

i am an engine machinist and have been working with performance engines for most of my life, and making a living at it for the past 6. any heads that i need ported, i send to a portworking prfessional, with a flowbench.

there is so much more that goes into portwork than just making a smooth surface, the velocity, curves, angles, volume of the ports also have a drastic efect on how an engine performs... and even in some cases ive seen ports that were too smooth (on the intake side)...

 

A fuel controller isnt really worth the pricetag unless you have some decent mods on your car.
