especially in hollywood ;oP

The finned version from the mini joint doesnt show the finish of the jp samples above but to think the cost was 240 when released here locally, it does show how much of a mark up that Jpn businesses enjoy in a predominantly wealthy country. I will be happy spending 900 for the high port head illustrated in my pic and then can spend money on extra anodised lids in case I get sick of one :)

Rallytwit Tom do you think theres a benefit from higher placed port for NA like the L series tuners use?

benny,
can u get sumps for a-series made from japan too?

cheers

D , sorry for the delay on my reply. In answer to the question, yes I do believe that a modified intake port would bring big benefits. Yamaha has been doing that for some time with positive results.

Tom

works raised-port head for A-series

what does that high port head flow c.f.m

C.F.M. numbers were undisclosed, but said to be "adequate".

that's not the right answer I was after,whats the big secret

I do not know the CFM numbers.

"numbers were undisclosed" cant get clearer than that!

Well it actually looks like the corolla high port head
but for eco-reason corolla chambers dont allow big valves
so although great ports on later heads no reason to be.

Tom, Im contemplating doing it to an early a10 head or
a12 head so can use the small chambers so less welding.
Maybe valves look like will have to come from an L series
head maybe L16 but currently only have L20b head valves.
Also will like to weld up the inlet valve guide area so
I can move the inlet valve out a tad from the exhaust to
get less overlap bigger valves to suit 83mm bore sleeves.
But the sleeved A is the very last project atm.

ok
