Bumpin it up!
Peter, any flow #'s on the 42.5/36mm valves? Using 7 or 8mm stems? Whos doing the work? I'd like to upgrade mine as well to take advantage of the massive sized ports.

I'm currently tearing my motor down and its getting poked and stroked to 2.2L, all ES goodies I finally get to put to use.

Collin the old school VW wiz

7mm stems... my spare 42/35 head flowed 182 cfm with 8mm stems... As soon as I get the head back I'll have it flowed on the same flow bench for comparison purposes... I've also got the flow #s prior to the upgrade as well...
I'll also be reflowing my custom counterflow intake manifold with the upgraded head as well...
Nice to see another old school Eurospec head being put to good use

Under wraps until Andrew drags it

PS: a 2.2 counterflow 8v is going to rock

I sure hope so.
Should be fun watching peoples faces in the rear view when a "girly" Cabby blows their doors off.

Oh, and I can still say "yeah, its just a 8V".

I think I have been on this list since day one. Had the head for about 5 years & finally getting it bolted to an engine. Stock JH valve size on mine. I did the head rebuild myself, new guides & cut the seats. Nothing special in the way of making it better. I also match ported the intake myself.



Done...

Well sorry

Actually I've heard rumours of the 42/35 Eurospec heads hitting 197cfm or thereabouts... so I'd like to actually flow mine (when it gets back) to put my own curiousity to rest.
My spare 42/35 solid lifter JH hand ported head (182cfm) had ports so hogged out that there was less than .2mm or so between the ports and the head bolt passages.

Can't wait to see the #'s! What max lift are you having the head flowed to? Did you do any additional port work, or is it "as cast"?

Re: Eurospec 8v head rollcall... post if you have one thx... (GLi_Luva)

.55". As cast but with larger valves... new seats, etc...

Hi Folks,
I'll have my head back this coming week but in the meantime thought i'd post some pics of a Eurospec head illustrating some differences between the Eurospec heads and the stockers... and the newer style 42/35 valves... that Andrew S and myself had our heads upgraded to...
35mm exhausts with 7mm stems, 42mm backcut intakes w 7mm stems, undercut down to about 6.5mm... all I can say is that these should really rock


Filled in Lifter "galley":

Can these heads hit 190-200 cfm? Should be interesting to see what the #s are.
 
#121 ·
Re: (MkIIRoc)

hi Kris,
I don't think 200 cfm with the stock Eurospec ports is possible... it does beat out my ported to the hilt 42/35 spare head though... the figures for that are up there, but are with the valve guide completely ground away...
As you can see there is a bit of a gain from the backcut on the spare head...
 
#123 ·
Re: (MkIIRoc)

160cfm at .4", 170 cfm at .45", and 176 cfm at .5" is still nothing to sneeze at... about a 35% gain in flow over the stocker JH head at .4" lift...
I can say though that the original low lift #s in the EC Eurospec head article appear to be bogus...

Re: (Peter Tong)

Re: (dennis2society)

Same company, but the link you provided is for the standard rebuilt heads. The performance heads varied in price with the race heads around $3500 or so.
This weekend during my rebuild, I found I mis-measured when I first bought my head. I have 36mm exhaust valves in mine.

.....man even with the standard hydro head which I got with a G grind/adj cam, I still got my moneyz worth, since in my opinion gave better performance than the oe mechanical head. which cracked between the valves with a mileage of 280k......
