Kent aluminum head???

cboggs · 25 Nov 2003, 15:51 (Ref:794138)

Hi Gang,

What's the word on the aluminum head for 1600 kent getting approved for use?????????

I'd like to talk to some UK engine builders if this happens, .. .. since we build the aluminum head that won the US FF championship and the Canadian championship, ..

Why on earth would anyone want to allow a new ally head?

What's wrong with the current one?

Based on recent debate re: weights and dampers etc. I can't see anyone wanting to change the FoMoCo engine regs surely?

interesting - I hear Ford are going to nothing with Zetec or Kents as to replace either would cost money and some form of subsidy from the mighty FoMCo...and they have nee cash and nee committment to the cause at the moment..

Its already in use in the US I believe, basically an Alloy version of the existing head - no help to engine performance but helps car weight, and C of G. Not legal over here - and easily spotted !

yes, it's used in the US and Canada as I'm one of the porting shops that builds them. My port design won the US & Canadian championships in 2003.
The port design is just like the standard Ford head, .. just an aluminum replacement.

Some-one told me FIA is going to approve the aluminum head as a replacement part, .. .. that's why I asked.

I tis available over here, Burton sell them

I'd dissagree with the performance advantage, LAlly dissipates heater better doesnt it? its also lighter (although unless you incorporate it with an ally block surely negligible?)

If the castings are midified slightly, surely it could lend itself to better porting also.

I'd like to get hold on an Ally precrossflow head, but I guess thats unlikely!

spearce · 26 Nov 2003, 11:28 (Ref:794910)

Curtis, its not an FIA decision, the FF1600 regs come from Ford - unless they give it the OK the ally head can't be used over here.
There still seem to be plenty of standard cast iron heads available, but blocks and cranks can be a problem sometimes!

zefarelly · 26 Nov 2003, 11:44 (Ref:794932)

I'd say blocks are the biggest problem . . . .arent you restricted on over bore size?

I dont know what the crank spec is, heads either for that matter, but I've just got rid of 3 or 4 std GT xflow heads for relatively little money

cboggs · 26 Nov 2003, 14:56 (Ref:795093)

Humm, .. I was told the FIA was involved in this.
You guys know some one I could call or e-mail to get the full story????

I think your engine regs and the US regs are close to the same. There is a slight performence advantage with ally since it can be ported a little different.
The casting is the same as the ford iron head, .. just a little thicker.

We are restricted to stock bore size so we end up sleaving the block every other rebuild, .. I hate that.
Blocks are a problem.

The SCCA has a nice crank made, .. so no problem there.

Your not supposed to port your heads at all over here !!!

I think that the porting regs are the same for both sides of the pond - the ports can be opened up to very specific sizes (essentially the maximum that you'd ever find in a stock casting) with the flange end of the port a specific maximum also.

The higher heat transfer rates of the alu doesn't necessarily mean that it will produce any more power - in fact, the reduction of heat in the combustion chamber from the draw-away will mean that LESS power is made.

cboggs · 26 Nov 2003, 15:56 (Ref:795159)

Yes as I understand the regs, .. you can port the head but the port opening and the valve sizes must meet a spec in the rules.
Also you can not add to the head, .. welding or epoxy, ..
Same as the US regs, ..

The Alu head does take heat away from the chamber faster, .. but there are things that allow it to make a little bit more power then the iron head, ..

True on your last statement. I should have stipulated "all other things being equal".

cboggs · 26 Nov 2003, 20:50 (Ref:795462)

MA2,

right, .. ..

sooo, .. again I wonder if this is just a crazy rumour or if the aluminum head is going to be allowed???

well no ones making new iron ones . . . .so why not

maybe my old iron ones will be worth something !
