 $50 each plus $15 shipping for up to four at a time.
 Lots more machining on these than on the manifold.
 Sorry about the bad pics. My camera had sanding dust
 on the lens :) will fit both Mazda (Nippon Denso)
 and Lucus injectors. Also I think Bosch but I am not
 sure because I don't have one.

 Send checks to me at:


 830 East Santa Maria St.
 Suite #303 <<<<<< very important.
 Santa Paula CA

Paul,
I will take four, putting check in mail today.

The picture did not come through for some reason.

OK Bill.
There were two pictures. I do believe there is some message size limit set
somewhere on your end. Here is one of the pictures. Please let me know
if you receive this one.

Did anybody else miss receiving two pictures with the above message?

Paul Lamar

Paul, do you use the Mazda injector diffusers in these runners.
IF yes, do you use the primary or the secondary injector diffusers.

Thanks

Rino

No injector diffusers. My thinking on this is they are not needed.
The fuel should have plenty of time to vaporize. More injectors
are coming on the market that claim a finer spray pattern. Lucas
is one of them.

Paul Lamar


Thanks Paul, I think I will try that.  The diffusers would be right in
the air flow and I suspect they would create a lot of drag.

Rino

Yes, with this runner design the injectors are not in the way and
yet they shoot straight down the pipe. That is one reason for the S turn.
the other reason is to get the fuel rail down below the cowl line
and still make it easily serviced.

I notice MSD came out with a ball valve injector. The Nippon Denso is
a needle valve and the Lucas is a disk valve. I wonder what will be next? :)

BTW I am going to weld these flanges together to make one wall
of the intake plenum. The rest of the plenum can be bent up from
sheet aluminum riveted or welded together and then bolted to
these flanges with small machine screws. With Tracy's EFI system, 
that does not use a mass air flow sensor, or a throttle position
sensor, air leaks in this area are of no consequence. 

Also BTW  use as large a throttle body as you can fit in as aircraft engines
run WOT the vast majority of the time. The idea is to minimize
the pressure drop through the throttle body. If at all  possible
use just one butterfly as that minimizes the pressure drop
for a given throttle body intake area. I think the Ford V8 has
a single 80 mm (3.2 inch) but I notice there are some 100 mm (3.9 inch) 
throttle bodies on the market now. Chuck Dunlap has about a five
incher on his :)
