Randy here is that stuff on the Ellison carb.

----------------------------------------------

Here is some stuff from back in the days we were considering
incorporating the Ellison idea into our stock Teflon slide
throttle. What discouraged us was the cost quotes we received
on the laser cut holes. If you can find someone to cut all the holes
this is a real good way to go.

Hi you Guys

Here are some pics of the spray bar of the Rotec equivalent to a MP3A.
I can dissemble the regulator and post some pics if anyone is interested?
Nicely made and the seals look good has a separate idle fuel adjustment as
well.

Looks like and exact copy of the Ellison.

Price is $976 USD less shipping.

All you need for a P-port is two :)

So far Slide throttle with EFI seems cheaper to me. 4 injectors $400,
slide throttle kit $175, teflon $40, Injector controller (?) well, that
is the only varible left. There's $1400 left for injection control. What
do you think your EFI system will come out at? $100 per board? Another
$100 for MAP sensors? Every system needs fuel pumps.
Am I missing something?

I was joking Craig :) Obviously nobody is seriously considering two
Rotec's or Ellisons as I recall they are about the same price.

Well the 555 system is definitely cheaper but it has not run yet.

Yes Klaus has run one but I am not privy to the schematic.
Yes the Megasquirt will work.
Tracy's system is pushing $925 but you only need one.
Yes it has two computers for redundancy.

I was thinking of incorporating the Ellison principle in the
slide so not much money would be added. Just a long brass tube
with a bunch of tinny holes and a lever to rotate it.
Any low pressure fuel pump would work.

It could be retrofitted to current slide throttles.
