fair enough

[Excursion]

It looks like a child has been let loose with a Die Grinder! The ports aren't even symmetrical.

thanks for that but you are wrong im no child and you can clearly see the pic is not straight,i could take the same pic of that port and make it look off to the other side.

[Ruishy1]

mark, i thought a man of your calibre could see the photo was taken at and angle

[crazycage]

just taken a new pic of that port but you will prob just find a new fault with it but here it is anyway, seems some people dond believe in diy tuning.

[Excursion]

It's nothing to do with the angle of which the photo was taken; an offset angle would result in more shadow on one side, not an illusion of greater width. This is basic stuff. Photo's show nothing other than what effect your tool of choice had on the surface of the port, which is largely irrelevant to flow.

I'm not out to pick fault with what you've done, just there was some good advice earlier on in the thread which you advocated, but now seems forgotten.

It can benefit us all if you post the flowbench results from your experiments rather than pictures of the ports themselves.

[crazycage]

ok so why do these two look so off set ? if its got nothing to do with the angle? there the same port from both sides ,i cant see the pic on the lcd screen before i take the pic as its to dark in the port.

ill let my times do the talking this year

your trying to bait the wrong man mate, have you seen marks work

But flow bench results will help settle any argument, that and get a decent camera

im not trying to bait anyone my times WILL be better than last year mate expect to see me running in the 11s on the 1/4mile and sub 10sec's 0-100.

p-s ive just made the valve opening tool for the zetec head

[Ruishy1]

but will it be down to the head work, or are you doing any other work ?
head work in a FI isnt as big a deal as an NA,

just head work the rest of the engine will be as it was ,done a few things to the car to help put the power down but they wont make any difference to the trap speeds thats all down to power your right about the camera tho but its not high on my list lol.
will have some flow results before and after at different valve lifts on monday and i will put them up good or bad that head is only a practice one like i said from the start.

[Ruishy1]

Its all about practice mate
what are you using for porting ?

ill post some s**t pic's of what ive been using tomorrow lol

[crazycage]

that looks nice mate i have two st170 heads to do when ive had a bit more practice ,you got any pic's of the exhaust side ?

[freak power]

Looks massively polished but its not ( camera and light makes it looks like it is )

[crazycage]

cool looks like i have taken a lot more metal out of my exhaust ports but mine is for a turbo'd engine and the exhaust side is a big restriction on my car.

[freak power]

A friend that does heads wants to machine the Zetec head and fit some standard size inlet valve in the exhaust size and match the ports for the valves to increase spool for the turbo

i was thinking that the other day , have you seen the flow tests of the evo heads?? they flow the same inlet and exhaust side and are good for 600hp standard. there about 135cfm the same as the inlet side on the zetec head thats why ive gone so big on the exhaust there only about 100 cfm

I seen that trick with the inlets in the exhaust side before on the zetec so its nothing new that i have seen

Not seen the any flow tests of the evo b head but i'm sure Ian Howell will be doing some soon

Do you know what lift is for that figure? 10 thou?

was at .500 on the evo and .462 exhaust and .424 inlet on the zetec

ill take a head down to my machine shop and see about putting inlet valves in the exhaust side

[freak power]

Sorry didn't mean 10 thou meant .500 as you said

Not 100% sure of what was needed to fit them but i think it did need new seats fitted and valve reliefs in the combustion chamber around the valves to help with flow

yeah it would need inlet valve seats as there a good bit bigger but im in rush to try this yet

[crazycage]

not finished but here it is so far, this head will be ported till it is f**cked just so i know how far you can go

[freak power]

Whats the size of the exhaust ports?

What sort of tools are you using to port the head?

[crazycage]

25mm ports on the exhaust side. a few metal cutting tools and a porting kit from tweeks why?

[freak power]

Don't get the porting kit from tweeks as they as so dear.

get them from here

http://www.cromwell.co.uk/YRK2059800K

I would rather use this stuff myself

http://www.cromwell.co.uk/NOR2012408H
http://www.cromwell.co.uk/category_page/090412

I use 60, 120, 180 and 400 grit cloth

[dangerousdave]

if i were to get hold of a spare head would it just be a case of setting up on an angle plate on the vertical miller and stick a slot drill down it or ream it followed by a good polish?? i always thought there was far more to it than this....??

lol, so how are you removing metal accuratly then buddy??

with a die grinder by hand mate

[dangerousdave]

ha ha ha lol! well if it works mate.....

[crazycage]

ha ha ha lol! well if it works mate.....

apart from cnc ported heads thats how its done mate.

[dangerousdave]

i can use a cnc but its only a small ( 1m bed) 4 axis one, so would prob be unsuitable!... im on it next week making my inlet adaptor ive spent the last 2 nights drawing up
