1UZFE Billet Heads

[AeroPC]

Guys
Had to make some billet heads to go with our billet block.
300 on intake, 250 exhaust. Flowed for blown alky racing.
Will be machining soon - then testing. Keep you posted.

Gorgeous stuff Paul!

wow, these are beautiful. You dont use coolant jackets/passages for your drag car right?

I noticed the square ports, is there a reason for that as I would have thought a round port would flow more is is this a result of tight packaging?

Doing away with water passages you have a lot more options on port routing.

Did you do anything with valve angles and size?

It looks like the only UZ items left will be the crank and oil pump?

A piece of art there paul, well done i must say

1 thing that zuffen didnt ask?
did you change the size or shape of the combustion chamber

Well done Paul,

I presume the is a billit supercharger manifold in the making too.

I'm off to the shed to go and polish something.

Guys
No cooling needed for methanol. I decided to keep as much standard as I could so cams, rocker covers, cam caps etc could all fit. Intake are 36mm exhaust 32mm - thats to get around 80% intake flow to exhaust - ideal for supercharged methanol. Its not all about flow - its about the gas path around the valve and getting good burn in the chamber. Exhaust is raised 15mm to give a better flow angle - and rectangle to suit the twin valves. Intake is a copy of the Hemi TFX type head - the more air in the better. I am going to try and modify the manifold I have, otherwise billet and billet rocker covers. 10mm spark plugs too that you can't see.
