Mr W will know for sure.

thats been skimmed then


balidey - 29/7/09 at 02:59 PM

I know what it is, I've been asking my wife to give me it for years


ss1turbo - 29/7/09 at 03:00 PM

Thats a HUGE set of valves...


wilkingj - 29/7/09 at 03:02 PM

Its a part of a fuel convertor.

It converts Hydrocarbon Chemical Compunds (Usually found in a liquid form) into heat and mechanical rotary energy.

This part is the Flange Pump Thrasher Unit and comprises of a complex valve assembly which you are looking at on its operating face.

So there... I know what it is

Where do the other 8 valves go?

Looks very heavy to me hope it makes a huge difference to pull all that weight!

Looks like the head off my old 1.6D tractor Astra.

That's a decent sized set of valves for an xflow, who did the work on it?


DRC INDY 7 - 29/7/09 at 06:57 PM

jpindy3 - 29/7/09 at 09:03 PM

nope.

standard GT is 34.0mm/30.5mm (ex/in)
these are 34.9mm/40.6mm but can go to 36.0mm/43.7mm - the last would need offset guides.

head was 150 off ebay, reasonably well ported but I opened it out a bit more, 320 for unleaded exhaust inserts and new guides plus opening valve throats for larger valves. plus cost of valves, about 80 soon adds up.....

spent last night and this morning blending in the opened out throats as there was a step. Used a piece of wire in waterways to figure out how much metal there was as didn't want to break through

in process of repainting then fit valves and slap onto engine after I determine TDC and make a timing marker to be able to use different pulley.
