Any one had their HEAD PORTED?

[Dangerous_dave]

hi,

thinking of getting my head ported this weekend.

got matched inlets and all breathing and hillpower cams



what sort of gain would it give?
is it worth £500 to get it done?


Fred / Revels / iccarus?

Cheers

 

[Fred@BTM]

no, unless you're doing all the fitting DIY etc etc and you know someone who does heads well

 

[franx]

i know someone who does head very very well .. ; the mrs.

she also does the fitting

 

[TooneySonic]

Hi Dave where are you planning on having the work done and what are the % flow increases?

Is the £500 fitted? Hmmm

 

[broster@JAM-Sport]

we have a head going thru development as we speak, should have it completed this weekend

 

[BenR]

This weekend?

£500 isnt going to get you much, and thats assuming your not including removal/fitting costs.

There are big gains to be had on the 172/182 head, however application is more important. If your running the stock inlet manifold setup, then any work carried out on the cylinder head is severely masked and gains are minimal.

As an example, my development program from a few years ago resulted in me being able to attain an 8% raw flow gain over stock with just one of our CNC valve seat jobs (none of this 1974 '3 angle' stuff), which provides great value for money.....however if you stick it onto a stock engine the gains are virtually nothing due to the inlet manifold.

Also the head requires quite some substantial amount of work to make modification worthwhile. The portshape as it is standard flows well enough, but you just dont have the material in the right area to modify it to a shape that provides an optimum port shape. If you just get someone to 'open' up the ports then the flow bench might register a bulk gain in flow, but that rarely is what we are looking for nowadays.

Relying on straight flow gain data is the wrong way to go about modifying a cylinder head.

The F4R is tricky and traditional methods dont work well.

Ben.......need my AGU ( VAG 1.8T ) head sorting out. What costs are involved and whats the turn around ? Thanks

 

[BenR]

As with anything, depends what you want doing.....parts supplied etc.

Best to PM or email me.

i know that CNC heads on stockport do it. They are very reputable. 800quid, but thats just for the polishing/porting. You would have to remove and fit yourself. You will probably notice a bit of a difference, but not as much compared to if you have a turbo/supercharger fitted.

How much does she cost

revels lol? he cant even make his bed!

 

[ben_p]

whos taking the head off, putting a new cambelt on too?

 

[Dangerous_dave]

ye cambelt being changed and dephaser, whilst hillpowers fitted @ Jamsport
was thinking of the head whilst this is all being done

 

[ben_p]

ahh cool

 

[Andyman]

I had my head done as part of a package of mods good few years back. Runs well

 

[Dangerous_dave]

ben_p did you get a stealth in the end?

i just got one from ktec got tired of trying to find one on here or the bay...rather pay the extra few quid and got a brand new one.

PMSL @ Revels! Boy has Angel eyes FFS!

It's not worth it tbh. I got 6bhp for 575£

 

[Dangerous_dave]

i knew he was mod so would assume his knowledge is good...

was that with other mods or just bolt on, i.e if i had matched inlets hillpower cams exhaust itg etc? is the 6bhp right the way through the rev range?

No peak. Mods were

Inlets, headwork, maxogen, Decat, zorst, Remap. 192.6bhp.

BenR has answered your question mate!

Traditional back street with an old flow bench work gaining bulk flow only does not reflect as gains on an F4R, especialy with the standard inlet manifold.

If you're going to retain the standard manifold then its just not worth doing.

flol!

 

[ben_p]

My car has had headwork, cams and ITBs and it made 220hp at faulkland (227 at GDi) and 233 at TDi north in warrington.

Ive just added a catback exhaust and decat, so intresting to see the results of that now!

 

[Gaz_]

-5 bhp

 

[ben_p]

lolz

 

[Icarus]

-10bhp

;-)

Actually, at present, you just have no exhaust...... well, one in a box, but no gains there!:rasp:

Pitot tube and velocity gauge FTW!!!

Even then, the only way to develope a head properly is using an engine dyno. A flow bench is great for velocity probing and checkin cfm figures, but it offers no real parallel to a running engine...flow into infinite volume, static valve position etc etc etc its just not a real enviroment.

 

[Dangerous_dave]

i have deceided against this, despite a very good price, feel my money is spent better in other areas.

Cheers for all the advice!
