I want to take about head porting what is the limitations of are heads.How much can I bore the intake and the exhaust.I want to bore them for as much power as I can get for non-turbo but still be able to put a turbo on down the road somwthing like stage 2.

Most pocket porting jobs give very good results when less than 5 cc's of metal is removed. More than that, you need a flow bench to see if what you're doing is helping or hurting.

word to the wise: dont fuck with it if you dont know what you're doing.

Ok frist off let's not get off the topic.And secend I would not be doing the porting myslef Iam good but not that good.realy all I wanted to know is what are the limtits of are heads being ported.As far as how big can I port be for I strat haveing problems like not being able to run punp gas any longer thing like that.I have done a full rebuild and i have an exta head that i want to have work done on.and if there is anyone that has had there heads posted let me know what sizes and what kind of gains you guys have gotten

It's as much of an art as it is a science. Shaping and polishing the ports. Do a gasket match and work from there. Just get the intake manifold ported and polished as well.

Our ported heads even get different work depending on NA or turbo. Just a little trick or two to help the two flow different depending on the situation.

I agree. Porting for a turbo application would be much different than porting for a naturally aspirated application. It also depends on how fast you intend to go on the head, as an extensive port job will do wonders for the top end, and you'll be wondering what happened to your bottom end.

I wouldn't take more than several mm of material off, any more and you're probably not going to accomplish much. As you already know, a a flowbench is critical to this type of work.

hey, well i had a full port job done by http://www.chrracingproducts.com

my car would be the one on the front page (=
go to http://www.chrracingproducts.com/Justpictures.html
look under my caar those are pics of the ports

i had the valve job, porting, the works, i did gain some good amount of HP, i need a dyno first tho....

but i have my flow charts here u go i hope it helps

this is all stright from the flow bench

Thats awesome. They are local for me. I will have to give them a call. I didnt know they were a Denver company.

-Chris b.

yea he does great work and he always keeps in contact, takes pics of the process, he really knows what he is doing, he hooked me up on upgraded valve springs...hope that info helped

Sweet! Are you Denver also?
What was his turn around like. I am going to call them when I get my MP throttle body and see if they can do some work on my intake mani and match it up to the MP.

he did all that work in under 2 weeks, then he shipped it over night, for free...

hes awsome he emailed me everyday with the work he did and pics
